iroc rims

phantom_mia · 07-18-2008, 07:36 PM

ive been searching for an hour now, does anyone have a idea were the "how to" thread on grinding or cutting the center out of a iroc rim (16incher) to make it fit a 1st gen is? ive seen it, and its i need to check something out but now i cant find it. please help. thanks

I did not realize you need to grind on Iroc wheels to get them to fit. I know for a fact the earlier Z28 five spokes bolt right on. I also know that you need to take off some material on second gen S truck wheels to get them to fit on first gens.

mine fit perfectly, but only prob i had was the inside of the rim hitting the control arm, i added a 1/4 spacer and problem was gone..

phantom_mia · 07-19-2008, 07:39 AM

youve probably got 4 rear rims thats why it hit the tie rod at least thats what ive read.

well i'll go ahead and try to mount them on the truck but i could have sworn ive seen were guys have had problems with the centers being to tight to fit over the hub and axel. the rims i got were on a 85 el camino

Nope,IROC's fit perfectly,even the z28's from 82-92.
You just run R/F F/R on the S-Series,or all 4 fronts.

phantom_mia · 07-19-2008, 01:47 PM

well crap mine wouldnt go on they need some grinding, with the added bonus i discovered i need a pinion seal and a axel seal what a great day this is turning out to be

MadMikeZ28 · 07-19-2008, 04:49 PM

Thats odd. If they were already on an 85 El Camino then thye should go on a S10. Do you just have some rust build up on the hubs

I have a set on my 2nd gen, and you do need a 1/4 inch spacer to run the front wheels (mine are '85) on the front of the truck with drop spindles. Otherwise, the rim hits the tie rod end. The rear IROC wheels need an adapter. I used a 1.25" topline billet one.

here are mine....i am aprox. lowered 2.5 inches upfront and i needed wheel spacers for mine since the tie rod grazed the inner rim and would not get past the wieght on the inside. I have like 7/32th wheel spacers on. But i would assume if i lowered the truck a bit more it would not need thespacers anymore. But anyways , heres the pics....

same ones i have, mine bolted right on. the zq8's and xtreme wheels were the only ones i thought you had to grind down.

what drop do you have upfront? I personally hate how mine is, the front wheel sticks out too much vs. the rear and i dont like running spacers anyways

88dimepa · 07-20-2008, 01:01 AM

What about Rs or z28 wheels. Which years directly bolt on a first gen?

jman · 07-20-2008, 01:02 AM

i have a 4" drop in front. my front wheels stick out a tad in the front as well. i don't know if running 4 front wheels would fix it or not.
