I will be LMAO.. motor build in progress!...
I guess it is all a preferance the rs3 has a tread wear of 140...the R888 is 100.. I dont have any issues with traction! but for the work the op wants to do I feel either tire choice will do.. the R888 is wider and taller..the Rs3 is CHEAP...money wise (never driven on them before).. Either way I say spend the money on the turbo kit, or build instead so he can make the 400Whp mark possible!

Tread wear isn't the issue. I'm talking about the chemical compound of the tread, and what the operating temp is for it. A cold UHP street tire is faster than a cold race tire.

If you're dealing with 400whp you likely want a 225/50/15 drag radial.

225/50/15 will work perfectly, or a 205/50/15 R compound.
I currently have 225/50/15 RS2s on all corners now and they rub a little everywhere. But they work. 225/45/15 would probably be better. When I am under power they rub like mad in the back. Also don't expect to get full lock when on a hard turn because they will bind in the front wheel well or somewhere in there. Not bind and make the car do flips in the air but you just won't be able to make full lock.

I nkow this will throw off my speedo, id there any easy way I can compensate for this? Does this sound retarted? lol Either way it will be different and I will have good traction. share your thoughts....
Details on your build?

How about you pay me a fat consulting fee when I put down 11 billion horsepower on thursday, buy some tires, and tell you what works? Or you could just do what has worked for others IN THIS THREAD who have already run over 450+ hp. Hint they did not run 5 lug bullshit.

This one?



I didn't fab it. Joe who is a fabricator at Altered Atmospheres (GT-R shop) did it. If you want one send me a PM with your cell and he can hook you up.


That's quite a build. What are you doing to it? Is it tuned? How much powa?

It's not finished...should be done late spring early summer. Motor hasn't even been cranked. Like I said, shooting for a reliable 400 whp if thats possible but we'll see. Everything is approx. rated for 550-600 with the right turbo.
