try driving a corvette or s2000, the Z is nothing. Heck, the 350 was more prone to spins than the 370...

True. Actually the z seems to have too much understeer from the factory. And my aftermarket tires seem to have made it worse. I'd like to modify the suspension and dial out some of that irritating understeer.

you can get a lot of it out by getting the same size front and rear tires, no need for suspension unless you really want to take it to the next level or you just want to spend the money. also the diff most of the time will do a one wheel spin a lot of time instead of getting into drift mode

Really! Do I get wider fronts or more narrow rears? I already played with my suspension so maybe it is too late, the understeer is gone already.

Wider fronts / narrower rears.

You want to increase the amount of front grip relative to the rear

DO NOT RUN WIDER FRONT THAN THE REAR. I tried it on a stock 350 , almost $hit my pants and crashed my car.

Whatever you run in the back, shove the same ones to the front. The car can take 295 in the front if not 305.

I believe I might still have a video of the car with the VDC on and off around the same track, the difference was 5+ sec. I still love the VDC light kicking on at 120mph because a crosswind hit the car.....
