c5 brake upgrade?
I have stock rims on my 89, will the c5 upgrade fit inside the stock rims?
Did a search only saw an issue with sawblades
Thanks

I think your going to have to run a 1/8" wheel spacer, I did on my 92 with the stock wheels but the 92 wheels are different.
It will work with minimal effort thou, as there are a couple of guys on the forum that have those same 89 wheels and the C5 front brakes.

Nice car dave!
Your 89 Charcoal Metalic convertible is the 3rd one that I have seen in the Twin Cities area.
Maybe are paths will cross.

I have an '89 coupe with the same OEM 17" wheels.
I asked the same question a few months back and received many "no it won't work" and some "yes it will work". One poster claimed that some OEM '89 wheels will clear the C5 brake upgrade while others will not depending on the casting numbers found on the wheels, but no casting #'s were posted? I still don't know if the C5 brake upgrade will work with my '89 OEM wheels.
Please keep us posted as to what you have done to upgrade to C5 brakes with those '89 OEM wheels. I'm still waiting to do this ~ if I don't have to upgrade my OEM wheels as well!
Keep us posted! Thanks.

I've got the C5 upgrade and 88/89 rims in my '91. You'll have to grind a little off from the cooling fins/ribs/(or whatever they might be in English). What I mean is that the inner diameter of those 88/89 rims won't have enough clearance without grinding a little material from the brake calibers.
You probably will also need to use some thin spacers (0.1 - 0.2 inches) to have clearance 'sideways'.

The link you posted is for someone looking to do a C5 brake upgrade on a '87 C4 not an '89 totally different animal!
'84 -'87 C4's are not the same as '88 and up C4's different spindles different fitment issues!
