I know there is whole section of the forum for brake kits but I thought I’d keep this in the competition section as I need some feedback from the racers.

production class is finally looking at allowing aftermarket brakes and allowing us to ditch the stock setup.

right now I don’t have an issue with fade and with the tilton master setup I’ve finally got balance and pedal pressure where I want it. I’ve got full ducts front and rear and that’s been helping with the rear temps.

running dtc 70 on front and rear (sometimes 60’s)

rotor life is a big issue. Cracking rotors etc.
pad life is horrible.

Looking at stop tech kits, wilwood kits etc etc. front kits all look decent. Rear kits seem to be horrible.

I started working with revolution brake to see what they can do and he’s got a setup that uses a 12.75 x 1.25” thick vented rotor front and rear (single piece) with a wilwood forged superlight front and rear. Kit pricing is pretty good and I’m thinking this is the way I’m going primarily because the rear kit would make keeping pieces and parts much easier as they are same rotor and caliper front and rear.

anyone have any feedback on the other kits from a full competition standpoint.

Anyone out there have feedback on revolution?

 

I'm assuming you dont' need the e-brake, right?

You can do the Stoptech C43/C42 kit front and rear. Replacement rotor rings are $100 as opposed to the standard ST40 kit, which is about $250-$300 per rotor ring.

 

Any front big brake kit is an improvement over stock, but I would suggest going with Urge Design's rear vented rotor setup. Their rear brake rotor setup is cost effective, utilizes stock pads and allows you to keep the parking brake, which is a must if you trailer your car to the track.

 

I’ll take a look at the c43/42 kits. Our new rules look to have maximum 4 piston calipers so that kit would be good.

I already have the parking brake gone. I’ve looked at the urge kit but it doesn’t get rid of the stock caliper which flexes and gives weird of wear.

Where'd you see them for that? The ST40 rings were even more than that when I was looking.

 

This is where I’m I’m struggling on this. A fully floating rotor would be nice over a solid single piece rotor. But can I justify it for over twice the price!

 

Found my invoice - circa 2018 - still a steal at the time. just gotta spend time shopping around and searching by part numbers - it pulls up all sorts of different vendor options.

 

The heat capacity and ability to shed heat is amazing and totally worth it. Going out on a track day and not ever having to worry about or really think about your brakes because you have the same consistent pedal feel all through out a ~2hr track day (split over 5-6 sessions) is totally worth it. Keep in mind this is on a 2700 lbs. track/street setup with full aero and NT-01s. Pad an rotor life are increased at 10x fold - 3 track days for OEM replacements versus 30 to 50+ with the ST40 kit.

On your car at probably 2200 lbs (less??) I bet you could go a full season without changing brakes if you select the right pad (of which you have a billion compound options from every manufacturer).

My philosophy with modifying the car is there are places you can cheap out and cut corners, and there are other modifications where you should pay money. Brakes are definitely one of those places, even above suspension. If there's one thing your car always needs to be able to do and do as reliably as possible without compromise, it's stop. It's both a performance and safety modification.

 

So I’ve been at this car for 4 years now and it’s been interesting so far.

production rules have limited us to stock brakes but pads are open. I’ve been through 7 different compounds before arriving at the dtc 70 with the stock front and rear rotors and pads.

im not doing track days, it is SCCA club racing and I’ve not had fade issues, but rotor wear and pads wear are pretty bad. With the new rules we are at 2636 for weight, but I’ve got a boat load of ballast and 49/51 weight split with 50 cross.

the revolution kit is using 12.75” rotors front and rear at 1.25” thick but they are single piece with a wilwood forged superlite so it would be a big benefit over the stock setup. But I’m wondering if going to the stoptech or wilwood kit would save some unsprung weight.

so now I’m looking at options with a 2 pc rotor to try and save that weight.
