Can you confirm that the MRT BBK uses C5 Corvette calipers? If so, did the calipers require brackets?

I am trying to put the pieces together here, so that I can release a "DIY BBK" for the Ralliart. The C5 Z06 had the same sized rotor (as far as I know) as the Evo IX Brembos. I just measured them. As long as the bolt pattern is the same (C5 vs. RA), then this should be a direct swap.

Great idea but i dont think the bolt pattern is the same. Pretty sure the c5 is 5x4.75
I think thats 5x120 in our terms lol
Would have been awesome because the rotors for a c5 are dirt cheap! its amazing how cheap it is to track that car.

But we definitely need some kind of brake solution for our RA's that wont bust the bank.
Thanks for doing what you're doing!

I was going to start trying to do a DIY brake cooling kit.

I know that it is. I have a set of Evo IX Brembo rotors sitting in my garage that I plan to use. I had them on the car earlier. I know that they fit. The calipers have a specific bolting up pattern, as well. That has nothing to do with the hub size.

Thanks, though.

Sorry! I misread. So you plan on using the rotor from an evo 8/9 and you are asking if the calipers from a C5 bolt right on or if they need brackets?

yep, it is indeed the C5 callipers (made by in pbr sydney) to confirm, i went to a brake specialist here in adelaide for different pads to use and the new ones installed were designed for the C5 and it was the perfect match.

as to brackets, im not sure - i can take photos with the wheel off on the weekend if you like?

Interesting! Does this mean the 17inch Enkei will fit with this BBk? Im assuming it will....

the stock 18" rims just fit with the mrt (C5) kit, so it might have a tough time with 17's... by just i mean i had to take off the wheel weights to avoid them touching

That would be helpful. I have a sneaking suspicion that the C5 calipers are the same mounting pattern as the stock calipers. However, they may still require basic spacing brackets.

I am almost positive that they bolt on. We already tried the Calipers from a CTS-V, and that didn't work. Those work on older DSMs. This pattern is really weird. I am thinking that it is the some one as the Corvette. For what reason, I am not sure.

Good info can't wait to see what you guys find out brakes are on my to do list next.

I have a set of C5 Z06 Calipers coming tomorrow. These things are DIRT cheap. It was $150 with shipping. That is absolutely insane. We are talking about full BBK in the front for $500-600. I will get working on the rears if the fronts work out. I have a sneaking suspicion that there will be a similar situation back there. Happy dance!

The C5 calipers require a bracket

You can see photos of the bracket here:

Darn! It would have been nice to be able to run a 17 in wheel at the track.
Oh well, ill trade 17in wheel for BBK any day! Hope this budget BBK works out!

Ooh im subscribing, this looks amazing guys, please do let us know what the outcome is to this, as i have wanted to do this for quite some time. The RA brakes kinda suck. Heatsoak i assume, really really bad if you try and slow down alot from high speeds
