zredbaron Posted September 8, 2005 Share Posted September 8, 2005 I have Ross's coilovers with his honda wheel spacers (4x100 if my memory serves me). I currently run 16"x7.5" wheels with 225/50R16 tires on the street (works wonderfully). My only body mod is a motorsport polyurethane air dam. I'm looking into getting a new set of wheels/tires for autoX / road racing use only. I was thinking 245 tires would add some grip. Surely some of us have tried this with these wheel adapters...results? Anyone have >= 16"x8" wheels and/or >= 245 tires? What's the limit without rubbing fenders? (I'm sure 245s up front would cause problems with u-turns, that's ok...race use only) Thanks in advance. Quote Link to comment Share on other sites More sharing options...
zredbaron Posted September 12, 2005 Author Share Posted September 12, 2005 Bump. I know, this topic has been in many threads before, but all my searches yielded results like "a buddy of mine has such and such tire with stock springs" or "yeah, that *should* clear" or "rubbed fenders, but i think that was because of ___." I am looking for solid experience, not just speculation. I can speculate with a ruler, but we all know that doesn't always work. I know that several of us have Ross's honda wheel spacers/adapters with coilovers. I know that my 225/50R16s fit. Does anyone KNOW if anything wider than that fits, front and/or rear? Thanks again.

zguitar71 Posted September 13, 2005 Share Posted September 13, 2005 Check into the regulations of the racing you are getting into, you might not be allowed to run that type of spacer/adapter. You might need to get a set of wheel that fit properly. Quote Link to comment Share on other sites More sharing options...
zredbaron Posted September 13, 2005 Author Share Posted September 13, 2005 A valid concern. I have looked into that. My mods unfortunately put me in the class FP for SCCA autox, which if competition is present, I should be in over my head. I autox in the Washington DC region, and for local events, no one minds that I run my NA 71 Datsun in the SM2 class. After all, Z06 Vettes and 300hp Miatas can run in it, so no is really worried about an old Datsun. Right O. So...not really worried about class restrictions, just fender restrictions.... But thanks!

Z-Gad Posted September 13, 2005 Share Posted September 13, 2005 Although I have not run the adaptors, my 16x7 0 offest (I figure +40mm offset on your honda wheels and a 40mm adaptor still yields a 0 offset) wheels have 245 width tires on them and I had to roll the lips in and slightly 'persuade' the wheel arches out to allow for clearance.

WickedWild Posted September 13, 2005 Share Posted September 13, 2005 I run the spacers/honda rims. Currently have 225/45/17 all the way around. With a little fender roll the 245/70/17's will fit if you have the proper coil over. If your conserned about the fitment, call a couple local stores to see if they have any of the 245 size in stock and if you can come in for a test fitment (tell them you'll order the tires thought them). *edit* Keep in mind that there are differences in 245 sizes from brand to brand.

zredbaron Posted September 13, 2005 Author Share Posted September 13, 2005 245/70/17 will fit? I assume that is a typo...did you mean 245/50/17? (or 40 profile? 70 would be huge!) thanks, though. i think i will ask local shops for their help as you suggested... Quote Link to comment Share on other sites More sharing options...
