Question about IROC's with 15" wheels....
So I've seen a few super low mile IROC's lately that have the factory 15" wheels. So I got to thinking..the 16" wheel IROC's have a different steering box than any other 15" wheel cars. The 15" wheel cars have a tighter turning radius. So are 15" wheel IROC's the same way? Did they get the RS and sport coupe steering box?

Re: Question about IROC's with 15" wheels....
I had one of those for a very short time & I just might have a picture of the SPID decal if that tells anything at all? Funny, I was just last week talking about those wheels on the Irocs with a friend of mine. I still remember driving past the local Chevy dealer in 1989 & seeing one parked out front & instantly knew something looking amiss.
Was told later that not everyone liked the harsh ride, but wanted the Iroc look. Any truth to that? Why did they make that change / option?

It's always been my understanding that the 15" wheel Z28 box and the 16" wheel Iroc-z box was the very same unit. The ONLY difference was the internal steering stops in the boxes were tuned for each wheel size.
Also it's worth noting, the base Iroc-z in '88 used the old 15" Z28 wheel, as the standard Z28 model had been discontinued. The "smaller" 15x7 Iroc-z wheel didn't come along until the '89 model year.
