My r34 is rwd and holding 600bhp at 1.6bar so getting power down in low gears is abit of an issue at the moment.

At the moment I'm running pirelli p corsa zeros at 30psi and can't get any power down on full chatter below 4th.

I used to run rsrs on my s15 but torn between the ad08's or rsrs.
Anyone has experience with both?

Also running a nismo gt pro 2way at the moment so don't know if that has something to do with the issue?

Help is appreciated :) thanks!

I have driven a trackday with a hired Scirocco R on Federal RS-R and found that they went off quite quickly and needed to cool down again before they could be driven hard. Generally they have a good reputation for lighter cars, but the heavier the car the worse the opinions get. So for your R34 GT-R I would go for something different which can take more heat.

Set your cold pressures to about 22psi and once up to temp they will get up in the range. Also on a rwd car, try and be progressive on the throttle don't just mash the pedal and expect it to grip with 600bhp. Your car is not an F1 car. ;)

my supra ran a hks 3.4 stroker and a t51r spl bb at 2.1 bar of boost, 788 hub hp.
Pirelli pzero 305/30/19 tyres 0 - 100 mph in 9.7 seconds
changed to toyo r888 295/30/19 0 - 100 mph in 7.3 seconds





and a vid at 1.6 bar of boost up my drive, about 700 hub hp




it was night and day changing to the r888s for me ;)

I've fitted some 265 rsrs. Amazing compared to previous grip!

Still struggling abit in second but LOADS better!

Nice to finally feel full boost properly :)
