Iroc wheels

[custom442]

Anyone have pictures of a G-body with Iroc wheels?

Also, how well will those fit an 86 cutlass with 255/50/16 tires on them? Should the fender wells be trashed and shave up some steel?

255's are a no go on the front as far as I know, and I have rolled front lips on mine. Also, only the fronts will fit without spacers as F bodies use a staggered offset which is different front and rear.

I think the ones they sale on that site (and most to be honest) are all the same backspacing for all four (they're not OE stuff) ... so I'm pretty sure you wouldn't have to worry about front vs rear like you would with real IROC wheels. If you notice it's a 16 x 8 rim with a ET of zero, which according to their tire calculator comes out to a 4.5 B.S. which should be find for a g-body.

Still, good to check before you buy.

You can tell the after market from the real ones easy.
The real ones will have front and rear stamped on them.

should I run 245/50/16's in the front and 255/50/16 in back? or the skinnier ones all the way round?

I'm running 4 FRONT IROC rims on my '84 Monte SS with 235/60R16 tires on them. I installed a set of Suspension Techniques springs which lowered the car approximately 1", and the wheels & tires fit fine. The inner edge of the front tires will rub the front frame and sway bar at full lock slightly, but I've never had any serious issues because of this. I alsi used the factory GM rear wheel spacer from an IROC Camaro or Trans Am from the late '80s (approximayely 1/8" thick) in between the rear brake drums, and the wheels, just for a bit more peace of mind. I went with the 60 series tires, because I wanted to fill up the wheelwells to visually lower the car a bit more without sacrificing any more ground clearance. The 16" wheel & tire combination that I'm running is about 1 1/2" taller than the original 15" wheels & tires that came on the car, so there is a bit of speedometer error that I have to keep in mind, but I really like the overall look of the car this way.

I am going with 245's front and 255's rear on my car. Just know that the 245's will rub on full compression in a Cutlass. How I solved the problem is in this thread: http://gbodyforum.com/viewtopic.php?t=5110

Sorry for posting another IROC question. When I got my Bu, she came with 15” IROC rims. Well, it’s been about a year, and I need new tires. The tires are 225/70R 15 all the way around. I notice that they rub up against the frame and inner wheel well , but I wasn’t sure if it’s a tire or spring issue sense my car bottoms out when going over dips. How do I find out if they are real IROCS or after market? Are they worth keeping, or would it be better to go with 16 X 8 instead? Can anyone give me some suggestions on what tire will work out best? Here are some pictures..

argh!

riddle me this, batfolks. WTF is that little symbol on the wheel in his second picture? At the outside edge of the bottom spoke? That looks like a similar (if not the same) symbol on the aluminum wheels on both my Mopars (the Mag and the wife's Pacifica).... is this a 'maker's mark' or something from the casting place? Just saw that and was like, hey!!

I would use either 235/60/15s all the way around or them with a 255/60/15 in the rear. No need to change rims. Naturally 16x8s are better but how hard are you pushing the car and how important is it to you. For most people its more about astetics. If its worth it to you to change the look a bit only you know.

On the 16x8s I have a buddy with a GNX which came stock with that size. He uses 245/50/16 up front and 255/50/16 in the rear and it looks and handles killer.
