Bit the bullet over the weekend and ordered some SVE Drifts. Only thing is, I didn't order the tire package. I figure I can piece it together and save a few $$. On the Brembo car, I have the stock 255/40 tires and on the Drifts, I'm considering 275/40s and 275/35s. I was leaning more towards the 275/40s, but by far the best deal I've found is through a guy in a local club of ours. However, through his shop (NTB), they supposedly only carry the 275/35s (Nitto 555). I'm curious with that being a lower profile tire that it will A. Throw my speedo off a bit. But this can be corrected through my SCT tuner right? B. Make the car ride a little rougher. And C. Make the fender gap a little bigger than the 40 series tires would. Is there anything else I'm missing and are all my concerns valid? As it is, I've narrowed my search down to the Nittos and likely the Hankook Ventus V12. I really wanted the Continental Extreme Contact DWs, but that increases the price significantly. Anyway, thanks for any insight you guys might be able to provide.
