Please help me, I'm trying to find the correct rotor (13") to mount on my rear to still keep my E-Brake functional. Does anybody have this information? Rear rotors for a late model Silverado came close but were 2mm to small on the inside diameter of the "hat". I have a challenge from a CF Vendor that if I can supply the correct vehicle rotor to accomodate the swap that they will supply me a set of 4 new drilled/slotted/cryoed rotors for free so I can do my install. In addition they will sell this as a set for others that would like the front calipers that say "Corvette" at all 4 corners. Any help will be much appreciated

Give porterfield a call.
I'll bet they can do it

Call Wilwood they have it already. The vendor should do the research themselves as they want to sell them all and hand you 4 rotors. They should atleast install them for you.

I'm new to this section and do not know yet who Porterfield is. Can you provide link?

They did some research but could not find the rotor match....man, I would be happy with 4 free rotors if all I have to do is post and ask a question

Just purchased an 02 ZO6 for track car and have some calipers from my C5 coupe lying around that I thought I could put to good use. For now I will be driving the car to events and as funds become available I hope to purchase a trailor. I did the "Spring Mountain" test before I purchased the car just to make sure I felt the excitement,......It is definetely there

Thanks for the info guys

Just spoke to Wilwood and they said they do not have the fix. Do you have any part #'s ?

I am all ears on this one

NemesisC5

I found them "on the left" ...thanks

Does Porterfield have anything? I didnt see anything their paper catalogue.

NemesisC5

I'll call tomorrow. Has anyone tried C6 Z51 rears?

Won't having the same calipers on the front and back throw off the bias in the rear?

I would be interested to see it will work though.

I believe I read that a bunch of the RAFT cars have fronts at all four corners, and do so without a M/C swap.

RC45

Good question.

The C6 Z51 rear rotor is 13", the C5 front 12.8". Hmmm.

NemesisC5

I've been told that although people have thought that in the past, it actually works quite well. Randy at DRM told me that they have experience with non E-Brake rotors on the rear and the system worked fine. He said the pedal travel increased slightly but not enough to bother you. Maybe he will chime in here and give us some insight about his experience. I hope I can find time today to talk to some people to give me a conclusive answer

Scroll down to post #8, there's a PDF on a "How To"

I don't know if they had drum parking brakes or not, but the 88-96 with HD Suspension had rear 13" rotors.

Actually only 12", and no drum setup. HD FRONT is 13".

my bad, I was thinking of something else I had looked into.

John Shiels

The pedal will be longer with front rotors on the back. I have 13" rotors on the rear and bias is no problem but I have a SL4 from Wilwwod on the rear so piston volume is the same as stock. LG had front calipers on the rear and said it was a longer pedal. Racerafter likes front on rear.

Thanks Hohn, good info, makes me want em more.....I know this is not much of an upgrade but even a small difference will be nice if I can use inexpensive replacement components to keep my operating costs low. Does Racerafter use oem calipers & rotors?

John Shiels

I believe so PM him
