Russ - to chuck in some idea's for the "street class" concept when it comes to tyres - back when I set-up the rules for the SAU Vic club championship we nominated a UTQG rating of 100 and lower to equal R Comps and anything over 100 were classified as street tyres.

This meant tyres like the Federal 595RS and Azien RT215 and RT615's were eligable for street class but they were about the best tyres available. But by using a UTQG rating you don't have to worry about tyre lists etc.

There definately would be a street car class, on street rubber(no semi's), this class is important, full interior & no cage, with a/c( if original equipment)

This will cause endless debate. But to me the street class should be on certain tyres, sure. But to say it must have full interior and no cage? So you are ruling out a safety measure such as a cage, inviting ppl to run crappy tyres with no grip and giving them the seal or approval to go crazy with hp mods? I personally think the street car class should be std panels (bonnet, boot, doors etc) with the option to run front bar and rear spoiler. The interior must retain std door trims and functioning glass etc. But should be encouraged to remove rear seat and install a cage.

Food for thought :D

Why don't you link the thread so everyone can see the discussion? You need to build a bridge.

Be warned Russ, if ppl don't like the rules and feel cheated by the result they may threaten legal action against you!!

Thats why you run under CAMS wqith CAMS officials and that way the Clerk of Course handles it all for you, using CMAS forms and usual means of lodging a protest etc :D

hehe! it was interesting in japan , we could run open class with all mods and no cage, heaps of freedom - not real wise but heaps of freedom.

the other thing i thought was funny, was watching gt500 race cars and lemans cars racing around mount fuji with full size tourists busses full of people also on the track!! haha that was classic stuff :D

You have hit upon an inherent problem. One of differentiating safety improvements (Which you want to encourage) from go fast improvements (which you want to delineate to help set up the class structure)

Over here in WA the sprint series is divided into outright & then a bundle of classes (eg 4WD, under 2000cc etc etc) The problem being that some people (eg me) turn up with a road car on R compounds. With a full interior, stereo, climate control aircon. A road car. Others turn up in a "road car" (well its got plates) on the back of a trailer with no interior, a full road cage, no ventilation etc etc.

So maybe you need an outright class & a road class.

But the safety aspect is a big problem. Personally I wouldn't worry too much about big hp cars with no grip. They just go slow anyway.

As for street tyres - well IMHO if people don't want to shell out for a half decent set of boots then they probably aren't interested in giving an event/series their full attention. Road tyres on a race track don't live long so it is a false economy you don't need to encourage. If it is DOT approved it is a road tyre. End of story.

LOL..yeh i dont think we shoudl be looking to the Japanese when it comes to running an event orcar safety. Their motorsport scene seems to do its own thing whilst the FIA go in other directions, most notably with cage design and requirements

top effort on your trip guys!

And with the classes there should be a 'street class', where full trimmed road registered cars can compete, we have no chance against the likes of giant!!!!

Haha, street car that turns up to the show and shine on the back of a truck?! You have the perfect set up to strip that car right back and make it a track whore.

I think this sort of event could lead to something big here. It would be great to get 'sprints' out there even more.

As for tyres, i think there should be no class for 'street' tyres for a big event like this. Simplify the classes to drive type and a levels of tuning. Semis arent THAT much more than some good streets anyway. however, i can see there being a clear advantage stepping up from semi's to full slicks. hell, just make it Re55's as a controlled tyre.

look forward to seeing this happen!

Edit: djr81, you are on the money

I can hear what you are saying but disgaree with some of your comments. :)

Its not a matter of the big hp cars being slow, its partly a safety thing. Think back to Tod Wilkes when wing nuts run events and dont think enough about the safety of entrants. :D Todays premium road tyres are no bad things and can still generate large amounts of grip, and cars can still go damn quick. Hp never hurts, but tyres are a great equaliser :)

Also, back when i ran road tyres they laster forever. If i locked up a brake? No problem. They never really flat spotted. They woudl get slick and greasy but tyre wear was never worse then i get with a semi. It was actually a lot better. I made the mistake of running practically new road tyres once, never again. They sucked and they did wear a lot initially.

I think there shoudl definitely be a list of tyres that are able to be run in a street class. Using the UTQG is an idea. But it means ppl at the budget end of the spectrum will be tryign to do with $1560 tyres what otehrs are using $550 tyres for. A list of tyres all with good performance and within a certain dollar figure means that the entry level class is entry level. Its critical that this class appeals to many as there simnply woudl not be enough serious cars to fill the ranks otherwise.

Ok I hear what you are saying, but the Wilkes thing is a fairly singular example.

The few times I tried road tyres in my R they just chunked. So maybe it is a weight thing.

As for tyre regs over here what it has meant is that you run RE55's, Toyos or other R compounds. Yes you need to fork out for them. But to be honest as I said if you are in any way serious about winning anything you are going to have to. I burn more money in fuel/fees/brakes/broken bits than I do in tyres. So I don't think people should over emphasise their importance. If they have to porper "road" tyres (not sure how you define that) then people will end up settling on something like a Federal or a Falken. So it will have much the same outcome.

As for safety - well I reckon this will be an increasing problem. 600hp is easy to get nowadays. Used to be damn near impossible. I mean, crap my thing will do over 200km/h at Wanneroo which starts to get me all puckery if I stop & think about it. Hill climbs are getting harder & harder to get approved & they tend to end up with more bloody chicanes, year on year.

But to be honest as I said if you are in any way serious about winning anything you are going to have to. I burn more money in fuel/fees/brakes/broken bits than I do in tyres. So I don't think people should over emphasise their importance.

I spent $4500 on semi slicks this year. I know ppl that have spent more. But that figure killed me this year and the cost of them really limited the track days i did :)

I dont think the serious = semi slick thing need be the case. If you dont need to run $1600 tyres because other competitors arent then? Even better is that a street tyre from a designated list will still probably serve you well as a road tyre for another 10,000kms :)

Anyway....i just want to help someone build a quick track car... :D Making them fast is more appealing then driving them. Its also cheaper :D

yes really like the Tsukuba format so it would be the basis.

hey chris, thats good as we were giving him plenty of shit!! :D

hey annie!! make sure you tell darren to fit that passenger seat or you'll be driving his car! i 've seen your driving to and your ascrazy as mark.

F**k the passenger seat!! I want to be in the drivers seat... without him sabbotaging the boost either...lol

Haha, street car that turns up to the show and shine on the back of a truck?! You have the perfect set up to strip that car right back and make it a track whore.

Unfortunately I was working Saturday morning hence why the car rocked up on the back of the truck.

I would never strip the car out, i won't be able to enjoy it on the street then. If I wanted a race car I would have built one..

My 2c on proposed event:

- Roy has a valid point, street cars should have original body panels (excl. bonnet/bars/wing), although they should also have an interior and a/c, cage optional. Tyre should be whatever the rules allow, if you want to be competitive then street tyres are obviously not a wise choice, if you can't afford semis well that's bad luck.

- No shit box challenge!!! Last thing we need is $1000 barges with engines that will most likely 'disassemble' themselves leaving oil and bits on the track.

- Tyre rules will make or break the event, there should be a strict policy, I reckon Snowman is on the money.

:D

    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.   
    • If you are Ecutek tuned then these TCU tunes are anywhere from $550 to $700 usd. If you are not ECUTEK tuned, then it gets costly!    
    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?
