Greetings all,

I’m looking to install a whipple on my 26 GT, do I need to upgrade the rear brakes to brembos? I have it in my plans to upgrade down the line, but is it mandatory to do it before I get the Whipple?

thanks

I'd start with tires, than move to brakes.

Your brakes are only as good as the contact to the road. If you're planning on tracking the car, then having beefier rotors and larger calipers will certainly help with heat soak to the metal, as well as distributing the brake pressure across the pad more evenly.

Eventually you def should upgrade the brakes, but tires should really come before anything else.

your front brakes do 75%+ of the braking

Tires help, a better pad can add stopping power without the huge cost of replacing calipers and rotors

Not at all, the base brakes are PHENOMENAL, matter of fact a lot of boosted cars run even smaller/lighter brake setups to save weight/rotational mass.

Once you've driven with great brakes you don't go back. Adding 200 odd HP makes them a must for fast road or track driving.
But I wouldn't just do the rears.

What's the purpose of your build?
Drag racing or road racing?

For drag racing....your stock brakes are more then good enough... I have friends in 10 second cars with much worse brakes then what comes on new GTs with standard brakes

You can put a Whipple on without modifying the brakes. It just won't stop as good. I can remember blown cars on drum brakes back in the day.

I just put a Whipple on my '25 DH. I wanted the Brembos so the DH was a logical choice. I also put on a Steeda Stop-the-Hop kit, a Lethal double H pipe, Vapor catch can, and a double fan intercooler with high flow Bosch coolant pump. Those Brembos are incredible, but for straight up drag racing, you could put on drums and be just fine.

The Mach 1s (and I think Gt350s) had single piston rears same as the non PP S650. There was absolutely no problem on the track.

And for the record, non PP brakes are still Brembo's and do a great job. If you aren't tracking the car there is nothing to be concerned about.
