Hey Guys,

Looking for some advice on Brake replacement.

I am hoping to upgrade to 6 piston fronts and 4 piston rears.

My headache seems to be around the rears, being a M6 and parking on a sloped driveway. I need to have a working handbrake.

What options are available to myself and any recommendations for a complete setup: (Daily Driver mostly, Mosport track sessions 3-4 times/year) looking to spend $3,000 or less for a full turnkey.

Cheers

Chris

Somewhere I heard about using the HSV rears allowing you to keep the parking brake. This is the reason why I haven't upgraded mine either. I need that parking brake, and parking in gear isn't my idea of fun.

Before you sink any major bucks on calipers. Do a "performance" pad upgrade first. Nothing from the parts store. You will be amazed at the difference getting rid of the stock pads makes.

I can't speak for the price of the HSV rotors (I've heard they're rather steep!) but with careful shopping on Amazon, you can get a 2nd gen CTS-V setup for a tick over 2k, with all new GM parts (save for Hawk front pads, and Russell braided lines). Yeah I've been doing some research lol. Also, between the colours I found available, silver rears cost less than yellow ones, but yellow fronts are cheaper than silver ones. Oh and a buddy of mine has a powder coating business in Bolton, if anyone's interested...

You missed the part about needing the parking brake. Which I think is the draw back to upgrading the rears currently if you use the CTS-V setup.

I didn't miss it. You mentioned the HSV option in your initial post. If they do work, there's your (somewhat expensive) solution. I'd guess you'd still be under 3k total for everything going that route.

You could just keep the front calipers and upgrade to a better pad and rotor combo. Then do the HSV rear rotor and ctsv caliper. Done. Way under your budget. Install some front brake coolers since you do track days. Brake coolers are gonna be your most noticeable upgrade for track days since you have front brembos already. Cuts your fade in half. Just my opinion. No reason to spend the big money on 6 piston Vs. unless you want to.

No kidding! I didn't realize I actually did buy a 4dr vette. Now I have to pick and chose which one I'm modding this month.

Wildwood kit is 2k for everything for the rears and works with the parking break. You can easily get it done cheaper however

Are these the same part numbers as pace performance?? Is it true that with the 6 piston calipers you have to drill the bolt holes to a bigger bolt????

For a working parking brake you do have a few options. First, you can switch over to the Camaro rear (Zeta 2) setup, If you Autocross or track the car this will be cheaper in the long run, and will also improve the suspension geomentry. Option 2 is get a set of Squash performance rear brackets and then contact Specialty Group in Detroit, MI. Send them a set of G8 rear ebrake shoes and they can reline them to fit the larger factory Camaro rotors. Option 3, go with the DBA rotors, no brackets, Camaro or CTS-v calipers and pads but you will need to trim the rear brake pads to fit with the slightly smaller rotors.
