I have Iroc rims on my 87 sport coupe since 2008. NO spacers...everything seems fine. I am now going to put on factory size tires 245/50r16...do I need spacers for the back? I do not have them and had never encountered a problem. SOme people say you don't need them ? TrUE or FALSE?


thanks!

 

No, those .187 thick spacers are not required. They were first installed to cover a Engr. Dept, error and when the original stock was used they were discontinued.

 

Not sure I can buy that explanation. The spacers were used on any iron drum brake rear with 16" wheels up through the end of 92.

They aren't really necessary, but if I had them laying around I'd probably run them.

The Engineering error was the .187 difference between the aluminum and iron drum brakes. So the use of the useless spacer.

 

THANK YOU! For you help!






I've had them on my Sport Coupe and never had a problem since 2008 with 215/60r16. Now I'm changing to 245/50r16 and I wanted to make sure there would be no issues with the rims and tires rubbing anywhere. Your thoughts of 245/50r16 on a sport coupe, should be no rubbing eh? I did have 235/60r15 long ago on z28 rims and they never rubbed.
