I've pretty much decided on 17x8 torques in steel grey with some sumitomo HTRs in 235 40 17. Will there be rubbing issues with these on a stock height 05 wrx? Thanks.

 

Probably. They are both wider and taller than stock tires, plus the Rotas put them closer to the edge of the fender.

 

225 40 17 the safe choice then?

 

225/45 actually.

 

Here you go...



17x8 Hyper Silver Torques
235/40 Sumitomo HTR Z II
AGX Struts, set on 1 all around
Espelir ASD Springs (~1.3"front/~.8"rear)

Cranked a full U-Turn(full tank), no rubbing. Got about 3 fingers of space in front and maybe two in rear. Enjoy!

 

You'll be fine I am running 235/40 on my stock 04 STI wheels and have ProDrive springs and no issues.

 

Without rubbing, those must be some awfully narrow 235s.

 

i got my car a bit lower than traffic's car on coilovers running 235/40/17 and have no issues with rubbing...if I were to go lower i would have to roll my fenders ..17x8.5 on 235/40/17 bridgestone so-3's

 

wont rub..

 

Gonna chime in here and ask if anyone has run 235/40 r17's on a wagon? I am thinking of getting that size in a used toyo ra-1 for pretty cheap to put on my Rota SDR's for track days. My suspension is stock.

thanks in advance.

 

I know you didn't ask so I apologize if my advice is unwanted but it is not a great idea to run R-compound rubber with your stock suspension. R-compound rubber creates much higher loads on all parts of your suspension because it grips so much better. As such, running it with you stock suspension will improve your handling drastically but will also bring out the weak points and softness of your suspension. You will neither be able to take full advantage of the tires nor will your car handle very well at the limit. Lots of grip and a soft suspension equals lots of understeer and severe weight transfer. And going fast is all about controlling weight transfer...

 

Thanks for your response. I welcome any advice to this as I'm relatively new to tracking cars. The only reason me asking was because I could get them really cheap. I spoke to some instructors at NASA and they didn't mention anything about the suspension but pretty much mentioned how it hides mistakes and is harder to learn how to drive correctly starting out on R compounds.

Looks like I'll have to find a used 215/45 r17 Kumho ecsta 712 to replace the one with the plug so I can track it. (anyone have one?)

 

Yeah, the more difficult learning curve is the better reason to avoid r-compounds for now. I'd get something decently sticky that will hold up to the high heat cycling and abuse of tracking. That's more important for a beginner.

 

It depends on the tire and the offset. Under normal conditions I don't rub with 235/45s. WIth my MX's sitting in my garage... I'm not so sure.

I also missed that it was an STi. You can tuck 245s without rubbing on those.
