Performance Wheels And Tyres, Ideal For A Track

[Rosie]

I have the Nissan GTR34 18 X 9'S!

The Stud pattern is the same, but you need to run a Whisker off the inside of the Centre to Accomodate the Ford Hub!

And they weigh bugger all!($500.00/Rim from 'Just Jap', Kirrawee- Second Hand!)

As for Brakes, you can't have big enough on the Fronts!

- Rotors and Calipers!

All this sounds rather familiar.

Rays Engineering (Volk) was my choice based purely on the fact that they were the lightest wheel I could find and the reputation for quality. From a weight perspective the difference is huge and it can be felt driving the car far more than people imagine. I think Erko had or has the Work CR Kai..an equally good lightweight wheel and frankly far better looking than the Rays CE28N in my view.

I have run them from day one with Toyo RA1 semis which actually deliver reasonable mileage for road use, are road legal and grip like a b1tch on the track.

You are definitely on the right track though...unsprung weight is your enemy so get rid of as much of it as you can afford.

Brakes on these are a joke. My first upgrade was to the performance PBR calipers with DBA 4000 series rotors and DS2500 pads. I ditched the DS2500s in favour of DS3000s within a month due primarily to the fact that the DS2500 was struggling at the top end of its temperature range...beware though that the DS3000 is less than useful when cold. All in all a pretty respectable package that would be fine for track days etc. Most on here seem to have good results with the DBA rotors and a good pad combination...but dont be fooled into thinking a good pad is something like a Bendix Ultimate. Good pads cost money!

One of the cheapest upgrades in the braking department that shows its stuff in track use is a decent set of braided lines and high quality fluid....worth every penny, inexpensive and far better feel through the pedal.

Some well placed ducting would also be a huge help and once again inexpensive.

My journey through handling hell (let's face it these things are a barge) started with a BA with 70ish kms on it and to my suprise EVERY suspension bush was rooted. Rebushing the whole thing made massive changes, initially on a Dobisport/Bilstein combination which resulted in predictable handling and a far more sure footed car. I later upgraded to Tein performance which netted even better time reductions on track although I would question the need for them for purely road use.

Thanks guys, this has been heaps of help.

Im still having trouble with the forum, cant see what im writing lol, not sure if there has been any more progress on this?

I will definately start looking around for a good set of wheels to chuck on as im looking at doing a hillclimb at haunted hills in the near future.

Thanks again!

ive used many types of rims for track rims.

personal fave are my Rays Volk TE37s very light. 7.6kg for one rims (no tyre)

I would recommend buying some 2nd hand 18" FPV wheels that clear Brembo's, especially if you are looking at upgrading brakes in the future, and save your money for good R rated tyres.

Tyres to consider (not R rated though) are Falken Azenis RT615, Kumho KU36 or Federal 595 RSR.

If you want something even stickier but a lot more expensive look at Toyo R888 or Bridgestone RE55. I don't think the Yoko A048 are load rated for Falcons but I think they have a new range out anyway.

For rims:

If you have the $, Enkei have a new lightweight track rim out called the PF01 which is very light:

Enkei Wheels : 2009 Race & Tuning Series

The RPF01 and RP03 should also clear Brembos too but are a few hundred grams heavier.

Cheapest option and if you are very lucky is finding some Porsche Cup front slicks. These will probably have had too many heat cycles but will still probably stick better than anything else.

You could get some second hand slicks for about $800 in really good condition and they will absolutely flog any semi slick on the market.

My best time at Phillip Island on A048's was 2.03, with slicks it was 1.56

35R from the Skyline forums and LS1 runs the same tyres and he says at least 1.5secs a lap quicker at Wakefield then brand new RE55's.

The RE55's or anyother decent semi for that matter will cost you at least $2500 as well.
