Factory powerful cars have a more ideal control arm arrangement that doesnt camber in another 3 degrees when you floor it.

I agree - the camber gain on the car is quite high. Of course, we are set with the pickup points we were given, so we gotta deal with it.

I think most of the traction issues can still be solved with a linear, slowed boost ramp-up and proper suspension set-up. Maybe switch the compound in the rear to a Toyo R888 or equivalent? If it were me and it was a drag event, I would even consider a positive camber setup for the rear. But either way, my car is just going to be a 500-550~ whp street car for myself, so it's nothing too competitive.
