[The HACK]

I keep the same rotors on but bed in the track pads during the first set of orientation laps.

I've found that with my driving style this chassis does not like different pads front and rear. I drove for about 1 year with Cobalt XR3s up front and Cool Carbons in the rear and the combination SUCKED. Well, suck is a harsh word, but when I swapped for Hawk DTC60s all around, despite the Hawks not having the same initial bite as the Cobalt, I was having far more consistent laps and time with the Hawks. What I found, was that while having different compounds for a handful of laps were okay, they became a liability in the later laps. The front brakes will require the front tires to work harder and I would end up with the front tires being anywhere from 4-6 psi higher than the rears, and the harder I pushed the quicker the onset of "understeer" due to the fronts being overwhelmed. With equal compounds front and rear, I've not seen anything even remotely approaching the same weird issues with uneven temperature and pressure increases. The fronts and rears are never more than 1/2 psi apart (depending on what track and how 'frisky' I feel).
