Track Report: Rota Rims And P-cup Slicks..

[nick33gtr]

just run 20's with toyo semi's

Personally I would not keep pursuing with 18's or 9's for that matter.

Nissan designed the vehicle specifically for 20's and Brembo suggest a minimum 3" clearence. Is that not enough reason ???

As for Rota's...your experience with them says enough.

Nick,

with all due respect, do you have any idea how much faster 18" options are vs the 20" toyos?

I would not be competitive in what i am doing on anything in 20", simple as that.

20" is just NOT an option.

I'll stick with the enkei's for now, my experience on the 18's does in fact say plenty.

Have you considered having a set of wheels made to your specs? I am sure there are still custom wheel makers around that will build you whatever you want for whatever purpose.

Funnily enough i actually spoke to simmons wheels a while back about doing this; went to go down there for a measure session.. just before they closed their doors forever! But handbrake (on these forums) just got some from ccw wheels; i may go down that path as soon as his reports experience with them (they are 18's fwiw, and he's running slicks too). They are probably the "best" option, with far superior clearance vs any of the rays stuff.

Fair call, I just stated toyo's as they were the first to release 20" semi's.

I understand that your experiencing faster times with the 18's but at what cost???

You have spent alot of time effort and cash pursuing 18's and I applaud this but surley efforts could be made in other areas such as weight savings whilst still running 20's to improve and maintain consistent lap times ?

Im not having a go just interested in your efforts.

My philosophy is this: Tyres are No. 1 - the car is almost secondary.

When the r35 was released; the first question i asked was: what semi-comps can fit under the car?

Answer: 295/35/18's RE55's (thank god)

As soon as i had that answer, i purchased the car.

There were no 20" semi's available at the time, and over a year later the only 20" semi available (R888) is significantly slower than the RE55 still.

I would not have bought the car if more affordable/faster rubber was not available. Further, I won the 2009 NSWSS championship (by a single point) using that tyre, albeit last round on slicks. I simply would not have won on the 20's

FWIW, the RE55's are roughtly HALF the cost of the 20" OEM tyre and 2/3 the cost of the Toyo 888. The 2nd hand slicks i use are a fraction of the RE55 cost again believe it or not (GT series throw aways). So it may be counter intuitive to some but in this case the 18" semi and 18" slick options are far cheaper than 20's and much much faster (several seconds per lap) and just more apprioriate really. The tyres allow you to get so much more out of the car. And i have saved many thousands by using 18's - In this market, cheaper is often faster, more appropriate and more robust (despite the cost argument people throw at say rotas for example, you need to experiment somwhat). Anyway if you want to go quick, my belief is that you select the tyre FIRST and find a capable car that can accommodate the tyre second. I spent years with commodores etc with serious power and some setup that just couldnt fit a decent tyre under the car; it just didnt work. The R35 i reckon will probably fit a 330mm slick under there without too much additional work, the times we are going to see in the coming two years will knock your socks off if we can make that happen.

If you want a nice road car that can run good lap times for the occassional track day - the 20's are probably good enough. If you do a lot of track days (go through lots of rubber) you need a better option. That better option happens to be cheaper vs OEM (as it often is).

Never the less, after all that's been said, I still intend to get a set of Rota P-45R, which are similar to the Grid Drifts but with only 5 spokes, which means they'll be weaker.

I'm only running an R33 GTS-T , with sports suspension and street tyres.

I'm not interested in super fast lap times, just a bit of adrenaline every now and then.

So in my case with 350 kg less, less speed, heat, inertia and traction, I'd expect the Rotas to hold together.

Last but not least, there's no way in hell my wife will let me spend $3k on rims alone. I'd get kicked in the nuts so hard I wouldn't be able to drive anymore anyway.

these are the the rims i eluded to in my earlier posts that failed at symonds plains, its also interesting to run them up without tyres on a balancer after a few track days (or pot hole hits) and find out how out of round they become.....

makes perfect sense.

So your a Rota nazi but have love for ROH wheels? Your just well, strange!

[handbrake]

I have recently purchased custom forged mono block 18's from CCW in the states (Complete Custom Wheels is the company name)

They fit very well with the custom offsets and have good brake clearance. they have been in use in the states for time attack and similar Motorsport series for many years, and for over 18 months on an R35 GTR

I have the same second hand slicks mounted on them as Duncan has. Will be testing for the first time on Tuesday.

Duncan is aware of all this but as always he is carefully considering all the best options before leaping into any purchases, which is well advised considering the costs.

These rims are US$700 each ( which was better value when I purchased them a couple of months ago thankfully)

[LSX-438]

those looks good Mark. When you get a chance can you get a shot from the front, i need to see if they protrude from the guard (cams requirement).

Duncan here are some shots from the front and rear, maybe a few mm out of the guard but will probably tuck in with camber and lowering. John at CCW will make any offset so room to move.

[LSX-438]

that looks pretty good Mark, is that with the custom arms on? Camber on that top photo looks about 3* (much more than you can get with stock) but i might be seeing things?

[handbrake]

Stock suspension/control arms were on in that pic. Maybe a bit lower than stock though as the wheel was taking disproportionately more weight with a wooden chock under it

in that case, the wheels look great. much better than Wills (which stuck out a lot)

nice work, i reckon these are the best option for r35 in 18 avalable.

[handbrake]

Will had his offsets the same all-round to suit the rear, so therefore about 15mm out at the front.

This set up is to suit the front, as a result the rear will be tucked in a bit but surprisingly not that bad to look at, will wait to see how they perform Tuesday, weather permitting.

Maybe put a 10mm spacer on the rear?

I'm not sure why people are attacking him for buying ROTA wheels. I gurantee all the people crapping on have some form of rip-off or copy item on their car or in their house.

mm, my 2 cars, go for ur life:

probably worth noting i didnt build the 2dr myself. i have some cheap stuff, no blatant rip-off stuff tho.

Have you considered having a set of wheels made to your specs? I am sure there are still custom wheel makers around that will build you whatever you want for whatever purpose.

see my sig. if you have a set of centres i can make the inner and outer sections. our wheels are used by some of the cars in the sports sedan series.
