Hey, wondering if some of you could give me some advice. Got a local 1/4 mile event coming up soon and want to know does the size wheel you run make a noticeable difference to the times.

My S2 has 17's with Toyo T1-R's, last year when i took part in the event i used standard S2 wheels on the front with low tyre pressures.

All i need to know is will it be better to use the 15's again or should i just stick with my wheels?

Cheers
