Any good tire company makes tires for your car, you just need the size, which you have. Toyo, Goodyear, Nitto, Yokohama, Michelin, B.F goodrich etc all make tires that will fit. 45 ZR tires will be expensive, but worth it for the performance you'll get from them. Ask a good tire shop, and find magazines that rate all the tires against eachother, or ask others who have bought the same size tire (45ZR) from different manufacturers and see what they say. I bought 215 40 ZR 16 Toyo proxes for my stock SVT rims, and they are good.
