Toe in REAR will give you that straight line stability and toe neutral in FRONT will be the best for accomplishing what you are always looking for....NEUTRALITY. The last thing you want is understeer in these cars. The front end is already light and the design is inherent to understeer. Exacerbating those inherent characteristics makes ZERO sense.

Set up the car as you wish but you will be chasing your tail all day long trying to get the "proper" setup if you start with toe in up front.

My car is set with zero toe front 1/4 toe in rear which is the way I like at the track. Just saying all manufacturer's set up for understeer which is safer for the general public versus a neutral or oversteer set up. I understand what u are saying- my car is not set up for streets. Mike

it's my first set of nittos so hard to tell but based on thill times i would say mpsc are prob good for .5 to 1 sec at outside but more likely around .5.
my nittos corded at rear after just 5 days (3 at THill 2 at SP) however i had too much rear camber so i think 6-7 days is possible. Fronts are still fine.
