Taller sidewall always give better traction. Itās the same reason guys go to a 15 inch rim with 60 series sidewall. I make 9xxhp on the street on a 305/45/17, but all my suspension has been done. It still doesnāt hook sometimes depending on my road conditions and how warm I got the tires before...
Mickey Thompson Et street r is about the only thing your going to get hooking on the street at 800 whp. Also if youāre using the car on the street I wouldnāt go past 650 cause it makes the car less fun imo but itās ultimately up to you.
Iāll give you 20k for the car problems and all. Just kidding. Iād send it to a reputable shop, if you donāt know where to start diagnosing. Pm me if you want suggestions.
