I just flared out my fenders and also about to buy some spacers. On a 16 inch rim, what would be the widest tire that I can get and still get the best performance for drag. 245's will fit but I dont know if that might be too much rubber for my setup. I have a '94 hb with a H22 swap. What do you guys think? I like the nitto drag radials 555r. They make 'em in 245/50/16.
