Jersey Posted August 7, 2003 Share Posted August 7, 2003 Hey all. With my current setup - L28ET, T5, 3.54's and 215/50/15 Dunlops that measure only 22 1/2" tall...it's time to get some taller tires/drag radials for the track. I need something like a 25" and as wide as possible. Does anyone know what offset i can use that will sit the tire in as far as possible without hitting anything under HARD launching and also, just clear the outer fender lip so it will tuck under without hitting? I put a set of 205/70/14's on last night, which measure about 25" that are mounted on stock ZX 14x7 zero offet star rims and i think this is really going to help my 1/4 mile time. 1st gear was actually usable and it built boost unlike the shorter tires which did not creat much of a load. The only thing is that these 205/70's are super skinny and with the zero offset, they just clear the outer fender lip when the rear is dropped due to launch sag. Anyone with suggestions/experience about which offset i can get away with or a 2.90 R200? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted August 7, 2003 Share Posted August 7, 2003 I run BFG 235/60/15's DR's on the stock turbo rims in the rear on track days. I made the mistake of driving with them on to the last Reynolds meet in the rain and ... NEVER AGAIN!! It was a white knuckle ride once the roads got a little wet. From now on I will bring them with me if I go to any events further from my home. Quote Link to comment Share on other sites More sharing options...
BayAreaZT Posted August 7, 2003 Share Posted August 7, 2003 I have 235/60/14s on 0 offset wheels. That will give you 25.1" tall tires. I haven't had any problem rubbing but my fenders are slightly flared. Quote Link to comment Share on other sites More sharing options...
Jersey Posted August 8, 2003 Author Share Posted August 8, 2003 Thanks guys. Z-Gad - are your fenders flared also or do the 235/60's squeeze under the outer lip? Those are pretty tall in a 15"....about 26"? I'm wondering if i can get away with like a 25mm offset 7" rim, and go with like a 275/50/15 or maybe a 265/60/14. That would give me a little more contact with the strip. Quote Link to comment Share on other sites More sharing options...
Z-Gad Posted August 8, 2003 Share Posted August 8, 2003 Yes, they are pretty tall !! I too wanted better rear end gearing than my 3.70 LSD, but until the unit has to be rebuilt, I'll run the 3.70's. I went w/ the largest tire that would work w/o any other modifications... My inner fender lips are rolled in (up into the wheel well), but that was for a 245 50 16 street tire I was running that would rub over bumps. You could just roll the lips in if it is too close for comfort. Quote Link to comment Share on other sites More sharing options...
