I have an 89 IROC currenlty with the 15" IROC rims.

Anyone Running 17's???

Im looking at the Edelbrock wheels by Ultra. Their '409' series rims looks pretty tight.

Will a 17x8 rim with the back set 4.25 and offset -06(whatever in the hell that means??) fit on my car?

Also what does the bolt circle measure on these cars?


And where can I get some clear lenses for the blinkers in my front bumper cover????

Do they make clear ones for the fenders to?

Any help is appreciated

 

Yup, I'm running 17 x 9.5 (I believe) Artera 4th gen Firehawk knock-offs. not sure of the backspacing, I made some 1" spacers out of 6061 aluminum for all for corners. Fronts actually needed another 5/8" but they aren't rubbing so I'm not worried about it. I dont have any photos right now, but I just took some yesterday do I should be able to post them in a few days. I also have Hotchkis lowering springs, and it looks badass now.


oh, dont know if you wanted to see them on any particular car. I've got a '92 RS

 

you also have lowering springs on 17's, that awesome, just what i want.

When you bought the springs how much lower did they say the car would be?

 

Aren't IROC rims 16"?

 

Yes, but there were 15's too starting in 88.

 

Do the IROCs with 15s have the wonderbar?

TexasLT1, we have to see your car !!! post pics !!!

 

what is a wonderbar? And post some pics i wan to see the 17's.

I think these cars should of came stock with 17's.they look better

 

All IROCs with 16s came with a wonderbar (a steering box brace, which fits under the front sway bar and attaches to the frame on either side. There are after market versions from Spohn, Top-Down Solutions and Global West). I was told recently that IROCs with 15s didn't have the wonderbar. I'm curious.
