Good call although it is difficult to establish what the weight of a car should be. Wet or dry. The other thing is to get a good gain you need to do some fairly substantial surgery. 5% of a GT-R is about 75kg which starts running you into the list in your second paragraph.

Actually it is legal because it is only a restricted (rally car basically) licence. Just one of the multitudes of loop holes if you are going to try & enforce road regulations or versions of the same. I reckon that a list of mods be put up then competitors can pick say 3 (for want of any other number) of them.eg Set 1. Brake upgrade to A/M kit or ABS deletion. A/M suspension. Gutted interior. Gutted HVAC. Panel/spoiler mods. Upgraded LSD's/locked diffs. Gearbox upgrades/changes. Plastic windows. etc etc Set 2 (stuff that puts you into outright no matter what) Fully locked diff. No mufflers etc. Engine change eg V8 in a Skyline. Free Roll cage (bolt in) Seat Harness/seatbelt Engine mods to factory engine (Obviously changing to another type would put in in outright) This would allow people to bring & run most things in road car class but put the serious people into outright.

This, then is a street car? http://www.my105.com.au/classified.asp?id=7814

Well if you are satisfied you have removed the pads & the fluid as a source of the problem the next step is the rubber hoses next to the callipers, the master cylinder & then the callipers themselves. In that order. But I would still make doubly sure it isn't fluid related.

Don't get me started on group B for gods sake. Check this if you want one. http://www.anamera.com/en/find/list/index.html?no_cache=1 Do a search for Fords. there are a couple there for US $225,000. Cheap so stop sniffling an buy one.

Yes. For the vehicle to be complied on importation it needs to match the information sent in by the workshop in their compliance package. Invariably this means stock exhaust/intercooler/intakes etc. Ofcourse you can modify and have engineered all sorts of stuff subsequent to that.

Well here is hoping it will be a little less ignominious than the last time they tried to run a GT-R in a production car race at Bathurst.

It is pretty straight forward. Mods that may affect ADR compliance need to be removed. Irrelevent stuff can be left alone.

Well if you can afford $5k you can afford a Porker I guess. Those times are damn quick. Has anyone any links to some photos? I just want to pretend that was me there in my GT-R. However briefly. Please don't judge me.

Cmon fellas, someone in this world must have a V-Spec and a camera.

Some people remove the ABS others not. It is heavy, slow cycling & to be honest not the greatest unit ever built. But it is better than nothing. If after heating up the brakes go away either your pad compound is not up to snuff or other components (less likely) are suffering (eg rubber brake lines).

Here is the template for the 6 pot calliper on a 343 rotor. 6_3.pdf

Where abouts did they clash - on the diameter of against the spokes of the rim?

Thanks, that's champion that is.

Can I just recommend the following: DO NOT USE DOT 5 FLUID It is horrible, non compatible stuff that should stay on the shelf at the shop where it is offered. If you use the dot 4 - 600 fluid you will get better pedal feel whilst having a HIGHER boiling point for the fluid. Dot 5 is not better than dot 4 just because it has a higher number. It is, IMHO, rubbish that should not be used on any Skyline.

Stop it all of you. You are getting you categories & your cars well confused. The RS500 Sierra Cosworth was a longitudinal engined rear wheel drive car built for touring car racing. It was the evolution version of the Sierra Cosworth (hence the RS500 tag) and was introduced at the end of the 1987 season. In rallying the appropriate antecendent for the Escort Cosworth was the Sierra Sapphire RS Cosworth. Which had the same engine but with an AWD system. It was a rally car. It was introduced AFTER the track version. The Escort Cosworth shown in the first post shared a great deal with the Sapphire - basically the entire drivetrain with an Escort body shoe horned onto a cut down Sierra floorpan. The Lancia Delta Integrele first ran in an 8V form in the 1987 season - so it predated both the Sapphire & the Cosworth Escort.

My point was simply to show that it was possible, indeed common if you are looking at something like an early RX. Alot of the GT wings sold for cars would be illegal under those rules too. Hmm 3.13 certainly reads that way, but nayway. My point is that if you can generate a list of modifications that would constitute a race car then it is possible to allow a road car to have, say 5 out of a list of 20 (for the sake of the argument). Other things may be mandatory, yet more may not be allowed at all.

I agree, but there is probably a transverse vs longitudinal engine installation argument. You could reasonably argue the Audi arrangment is a bit of a blind alley. Also who is that twat from top gear?

Rather than go through all that again, have a quick look at this: http://www.camsmanual.com.au/pdf/3category...203J%20Q407.pdf Check items 3.4, 3.5, 3.6 & 3.13. The reason I would seek to allow street cars to run R compounds is that they are common as muck with people who already run their cars in hillclimbs and sprint events. Thinking back to the last one I entered there was not one car on road tyres. So the people who may be interested will already have appropriate rubber. As opposed to having to get whatever street rubber is closest to 100 hardness.

Cough, what would the Stig say to that?

Two things. 1. Stock parts are designed to work together as a whole. Rb26's don't suffer from valve float like say a Ford straight six - so the stock valves are good enough. It is common not to upgrade the springs when you upgrade the cams anyway, so not much point on stockies is there? 2. You can test the springs to see if they are still the right spring constant. So maybe do that before spending large on stuff you don't need. Oh and think about reshimming the valve train if you are pulling it all apart.

Some things I would do if my car was a race car, not a road car. Lightest wheels I could lay my hands on. Proper brakes. Proper suspension adjustment (ie large amounts of -ve camber at the front amongst other things) Ditch the HVAC system. Chuck the ABS. Chuck the interior including the stereo, seats, carpets, roof lining, door trims etc etc etc. Chuck the mufflers/cat. Stick a proper roll cage (ie one that links the suspension towers as opposed to a bolt in) Seam weld it. Run seriously offensive LSD's at both ends. Run lower diff ratios. Dump the stock body work for such things as vented carbon bonnet, new front spoiler. Proper gearbox eg close ratio gear set. Lexan side & rear windows instead of glass. Install CAMS required items eg 2 litre catch can, proper fire extinguisher. Thats just off the top of my head. Surely there is enough differentiation between a road & a race car to make a judgement call without too much controversy?

All GT-R's came with rear wings.

By struggle town I mean the unequal strruggle that is making a road car behave itself on the track. Why limit the cars? Why not have an open slather open clas? Then place limits on the lesser categories?

No idea, probably not. But my point is that a track car is an entirely different animal to a road car & also that they tend to be away in their own land anyway. Those of us in struggle town don't appear on their radar so having a class structure doesn't affect them. Yeah, except for the "Here's my time & here's yours, below mine on the time sheet" usually brings things to a halt pretty quickly.
