IROC owners
My knowledge of IROCs is very great but
I wonder if I might be wrong about this one.
I contend that IROCs with 15" have exactly the same suspension as 16" equiped cars,
am I right??
FE2 is listed in my glove box and computer selected springs are;6ZW,7ZW,8NL can't find the other one. Can someone with an IROC with 16" wheels verify the same RPO code/spring
codes??
thanks

88 IROC the best RS ever made!

My 87 originally came with 16" rims. Codes for it are.
6ZX, 7ZX, 8NL, 9NL
All are listed as "computer selected" so even though they have the same RPO the spring rates may be different. Only part numbers will say if the spring is the same or not.
