I went with BfGoodrich g-force t/a KD's on a whim. They were cheaper than michelens, or something like that, I dont remember why I got them. I have never used a stickier tire on my car. They are noisy and the ride is harsh, but they grip like nobodys business. I used the Michelin pilot sports, some Falkens(garbage I think), and the Pirrelli P-zero Assimetricos, I like the BfGoodrich tires a lot. I get a lot of people who think they are cheap crap, and cheaper version of Michelins since they are owned by them. The tire companies design there tires seperate from eachother, and though most Bfgoodrich tires are more affordable, its not because they are a lesser tire. Anyway, you may want to check them out. I also recomend checking out the Article they have been boasting in there ads, its a true testimate too how good the tires are. Using a g-tech I was able to pull .92 with those tires on 16" rims and iebach springs, and no that wasnt peak. Im using 215-50-r16's for the tires, so a 215 might work, but you also might get some rubbing, I do on sharp turns with an incline. K, thats my bit.
