Hello, I really need more traction with over 575hp and saw the Falken Azenis I tried at earlier and much loved..very good quality/price

The problem is very high ratio, 4.8% vs oem is 2.4% if I take the 255 / 40R18 and 295 / 40R18 for maximum width fit on my Enkei RPF1 9.5 & 10.5 with 15mm offset..i know it was in my fender but for the vDC, has anyone tried?

You have something else to suggest to me?

My other choice is Kumho XS 245/35R18 & 275/35R18 but the road here (Quebec) aren't like yours and would like more sidewall for comfort
