My car is a 600ps comp pack and in 2nd gear on a smooth road I get grip just fine with the 305/30r20 PS4S tyres.

For 1st, if I smash the throttle off the line it'll spin the wheels so instead I go to about 50-60% throttle to get it moving, then floor it. As boost starts to come on at about 2500-3000rpm I'll shift into 2nd. That will normally result in no wheel spin at all or perhaps just a tiny bit in 1st and will regularly result in 3.7-3.9 seconds to 100kmh.
Brad,
Thanks for the reply, and thanks for the description off the line. I’ve never owned a car with this much HP and Torque before. All will be well.
I have 265 305 set up now. I will change next spring 275/305 set up. There r many articles about tire size and under over steer etc.
who cares? Im not professional driver. Just floor it at straight line. Also i thin i can handle 50% amount of car ability at cornering. So cant feel anythinggoing wrong on corner. Just can noticeable at straight line. Feels more confident and stable. If possible, i like to put 325 on other rim. I hope this help u
Appreciate 1
