It still handles well and the tires won't come off, I think, under extreme cornering, but it might defeat the purpose of the performance tire. A.K.A. I might not reap the benefits of such a great performance tire. Also, with the lower side wall height of the Sport Comp, the sidewall deformation might even be exaggerated.

Yeah, I might not see a lot of benefit from an LSD, and certainly wouldn't be worth the hassle and expense of installing one on this auto trans, although I believe there migh be one available. I know though that I could improve my 0 - 60 time without the amount of wheel spin I get. I'd really love get close to 6s, pipe dream, I know. I'm pretty sure that 7s might be attainable with the right launch as the car sits.

I don't remember the exact specs of the factory rims but I cannot imagine the BFG's in the above size should cause any problems even under extreme cornering. Realistically the tire will start to give way before the bead and rim do. It is only a 340tw and even though it isd a sticky 340 it will not perform anywhere close to Hoosier slicks.

a 6sec 0-60 would be pretty nuts in a Yaris, but at the end of the day it's all a balance of cost and what it would cost to do a 6sec 0-60 would likely be quite a bit. Only you can make that decision but if you don't have plans to run the car at a drag strip or race it that price can be quite steep just for the sake of knowing it can run that fast. Like I said that is a decision only you can make as the owner and person who is actually paying to do everything to the car. It would be pretty wild though
