Hi guys, I'm new to the forum. Don't jump on me but I've already searched high and low on Honda-Tech and really need an answer or two on the difference between 13" and 15" drag slicks.
I'm currently using 15" BF Goodrich semi's, but realise alot of dragsters go the 13" slick route. Would my time improve if I opt 13", and if not, would 15" (24.5x8x15 Mickeys) slicks be a better proposition? I'm running a B18 box (with a 4.4:1 final drive) off a turbocharged B18B motor and cross the line in fourth gear at about 5000-6000 odd revs.

Damn I'm clueless...
