I've got some 275/40zR17's... hoping they'll fit on my 89 RS. Anybody know? It's ok if they rub a bit

 

What did they come off of? 4th gen or something? If kind of depends on the back spacing. Do you know what they are?

 

I have a set of 17x9.5s im trying to fit as well. what ive found by talking to people is i should need 5.5 bs on the rear and 5.2 bs on the front. my z06 wheels are 7.5 bs, leaving me needing 2" spacers for the rear and 2.3" spacers on the fronts. please dont go by these numbers as im not sure they are correct but see what you come up wiht and let me know. I can feel confident if we both find the same #s form different places. i think for now untill i beef up tranny and rearend im going to run 245 45 17s on the rear and 215 45 17 on the front n ot sure tranny and RE will hold the new 383 stroker and i need to get a set of sfc and lift bar before i fold the car up.

 

The wheels are welds, not sure about the spacing. They're on my 88 s10 right now, the pic's below. I've seen lots of guys put IROC wheels on their s10's, so I was thinking/hoping the backspacing was the same. Let me know what you guys think. (taking the wheels off cuz the s10 is gunna sit for a while, puttin a new small block in it)

 

Do you have some other pics of those wheels, what kind of welds are they?

 

I don't know what model they are, I didn't buy them new. All I know is that they're discontinued. Haven't been able to find extras on ebay, either.


These are just some old pics i had on my comp, I could go get some close shots if you want

 

got replies form several spacer companies they seem to think for my 17 x 9.5s with 7.5 offset i need 2" spacers all around making it an BS of 5.5 all around... you guys figure anything out??

 

I still don't know if they'll fit, so I am going to just try it and find out. Check this post in a few days and I'll let ya know. Later
