Pending your spring and rebound rate and how hard you are forcing your car through the turn. I ate up my Hoosiers at Ft Myers during Pro Solo and my car has stiff suspension but the instructor and I were hard on it non stop.
Also your tire pressure comes into play. Not to mention the surface you are dealing with.
As for the paint chips the cheapest investment is tape it up. You'll see you aren't the only one. Heck omgwtfbbq makes designs out of tape.
just my .02 . there are def some better and more knowledgeable people on here that can assist you further.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
