also snowy just on regs. wat tyres are allowed for the track days... am i allowed to use my cheater tyres or do i have 2 use semi's instead?

mate your signature is the best i have ever seen.... Had me in hysterics... Ho[pe i dont get fired form work... Bossess hereard me laughing... Oh well it was worth it.... Your a legend!!!!!! :D

:angry:

They can do the full FIA approved cages but if you are after a simple 4 point rollover hoop with tags to the B pillars they quote to do that for only $1050 fitted.

:)  <- I'm so glad this is back!

Cool. will have to be quick though as i understand CAMS are about to introduce new guidelines for roll cages (minimums) and some of the changes will mean a small increase in cost.

Any idea of price for a Chrome moly 4 point cage with harness brace? I cant really call them at the moment.

...and i dont think all this talk should scare you off, hopefully make you respect the speeds you do, but shouldnt scare you...i have done over 5 years of days now with only that one stack in the wet....which was as 1/3 brain fade, 1/3 bad luck, and 1/3 having no idea how to slow/stop a car in that situation :)

Great comments guys. A fantastic thread for all to take note of.

Since this regs change will affect a lot of us in 2006 I have spoken with Toby @ Meridian and we have setup a group buy on harnesses.

MotorQuality harnesses in red, blue and black. Group buy price of $329 for the 4 point & $365 for the 6 point harness -

Minimum group purchase of 5 harnesses

See here - http://www.skylinesaustralia.com/forums/in...howtopic=102480

Just cross them over on the way to the back fastenting points...and people then run the strap throught the middle of the headrests..but it is very dependent on the std seat...around the head restraint will suffice provided the seat shoulder isnt too cured...actually check with Meridian :P

Note to self: Never get in GTTR34s car as a passenger. It seems passenger have a tendency to piss their pants :(

Cool seat too...you dont find the Bride too tight everywhere? Though the angle of the harness is pretty accute. I dont know if mine are much better, thats part of the reason why im looking to change where my harness is secured to.

In an accident, the belts will want to straighten as you move forward in the seat. This puts a bit compressive force on the back of the seat. If your tall enough that the straps sit on your shoulders rather then the harness hole in the seat, that means your poor back gets the compressive forces.

Worst case scenario if you are using a dodgy Non FIA approved seat etc then the compressive forces have been know to damage fibreglass seat backs, causing them to fail....Just a word of warning if you are looking ta getting a cheap and nasty 2nd hand seat. Im even worried about my seat in a big acco as its now about 5 years old and FIA compliance has expired?!?!?!?!

haha actually that's what motul RBF600 brake fluid does to a seat :D

The shoulder strap angle is not less than 45 degrees downward from the harness holes, and I'm not tall but I'm taller than snowy :(

I wouldn't even bother with a cheap fibreglass bucket seat, I've seen them floating around for sale and even sat in one and they flex like all fcuk! I'd prefer a solid steel frame stock factory recliner than one of those things.

The Bride Gardis III seat feels solid, but it's very lightweight, as it should for a seat that costs so much :lol:

Once your seat expires, sell it off and buy a new one, get a fresh 5 years of FIA approval goodness :(

LOL...my seat has expired, but it still means i can use it at Sprints etc provided there is no obvious damage to the seat...which there isnt. And at over $3,500 i wont be buying another one :( Next seat will be a Velo or Racetech.

Yeh, the 45deg thing is a good guideline, but if your parcel shelf is well enough desgined, or can be gusseted to accept the harness, it is much more ideal...so thats what im hoping to do.

You are meant to look forward when driving onthe road, not behind you :D

Some would say its a bad habit, some say good, but i rely on my mirrors when driving, so never need to look over my shoulder..but the few times you need to it does suck..ie, last year at Calder at night when i had to reverse of the dummy grid, i couldnt see a thing :P

Denham - i dont usually wear the harness when im cruisin around, only sometimes when im doing a late night high speed touge run :lol:

but yeh the harness really does lock u in place.. i couldnt even twist my torso to shake Rod's hand thru the window at the sau meet the other night haha

I found two issues when fitting the quick release harness from Meridian into my GTR.

1. The eyelet bolts are a different thread size to the seat mount bolts at the back of my front seat. The back left bolt is needed for the lower left strap.

2. I was told by a scruitineer that installing the shoulder straps into the seatbelt clasp mounting position on the rear seat is illegal. It puts the belt on a fairly steep angle, close to 45 degrees.

They say that in a front on accident, forces will move your body forward and cause the driver seat to crush down and inturn, severly compress your spine.

Therefore, they only allowed harnesses in cars where the rear straps were mounted onto the parcel shelf or onto the roll cage at an angle to the shoulders of no more than around 15 degrees.

I know plenty of track day organisers don't pull you up on this but it is worth noting. I will be rigging up a mounting plate in the parcel shelf for the rear eyelet bolts.

After much deliberation....whether or not I wanted to lose the rear seats (still have enough kids at home that rear seats are useful), relative safety of harness v's 3-point std belt with/without roll cage, nasty photo of WRX rollover with uninjured driver etc etc etc. I decided to go ahead with the 4-point harness. Initially I mounted the shoulder straps to the rear passenger seatbelt mounts but likewise, found the angle was too acute. A trip to Meridian yesterday resulted in a very neat installation of a harness bar under the rear parcel shelf, with just the eye bolts poking through. If anyone is interested, Meridian took some digital photo's of the install and I can post them here when they e-mail them to me. Tried out the harness at Calder today and it felt much much better cornering with it on (hope I never have to find out how much safer it is!).

Cheers, and thanks to everyone for their contributions in this thread.

Please post the pics and how much???

Please post the pics and how much???

For manufacture and installation of the harness bar (which took several hours) it was just over $600. It's an extremely robust installation and all you can see of it once the parcel shelf is back in is the eye-bolts. Meridian haven't e-mailed me the photo's yet - I'll post them as soon as I get them.

    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out. 
    • Wife and I are still looking for a new home. One condition was a large enough garage for a full-size lift in one bay. Now if only we could find something... We've been looking for almost a year now.
    • Thanks everyone for the ideas! Sadly, ramps are a no go for me. With young kids at home, I do most of my work late at night while they're sleeping. Starting the car multiple times wouldn't be a great idea.  I'll go see one of those new long reach low profile jacks and take a couple measurements to see if they will fit.
