Wanted suggestions how to create low drag Wilwood brakes
 
Guys,
I'm looking for suggestions on how to create low drag brakes. I have Wilwood 4 piston caliper brakes front & rear on my Gen 3 GT/DA 92 Camaro. Is there a kit one can buy? The TDM brakes are out of the question.
Thanks for looking,

I shim the caliber with spacer to make sure they are centered
on the disc properly (usually they are not). They still have more
drag than the more expensive brands that my son runs on his cars!

As well as making sure the caliper is center I have small stiff springs I put between the pads so the cotter pin holds the springs in place.

Or Lamb brakes ….There are always budget minded racers that will take the Wilwood’s off your hands ,,..Lamb brakes = $$ well spent ….:):)

there's good reason why you won't find wilwood brakes installed on any car built for drag racing by a professional chassis shop

Doesn’t Wilwood offer a low drag “ o” ring to replace the square cut seals in the calipers?

Making sure the calipers are centered is a no brainer , but switching to drilled rotors was the best thing I did. No more drag. This and the right pads.
Mine are Wilwood.

Ed,
What have you been up to? I have seen you post in a long time. Do you still have the Firebird?

You ain’t a poor boy if you race. You maybe be a cheap boy though:D

Other than the front wheels turning during wheelstands have you folks with the low drag brakes seen any real improvements in ET?
Thanks,
Bill

For the hub, use the DRP front bearings, with their spacers and low drag seals. You will be a big surprise.

Honest Ed,
I wouldn't ***** 💩 you. I'm a POOR BOY. I haven't race my MPR 92 Camaro in 27 years. My car has only 20 to 25 runs on it. It still has the New Race Car Smell. I parked it when I got married in 97 and started my Family. So, with a little Luck and a few dollars. I might get a chance to race next year. And make some improvements.

Hi Ron,

The bearing kit is P/N 10585BR
The spacer is P/N 10521s
The seal is P/N 10577
Get also their low-drag bearing grease.

Call them.
They are some of the nicest people to deal with.

This is a link to their catalog.

Changing the square ring to a round ring helps. Still not Lamp but it is better. Then install low drag bearings with spacers. Remember when doing all this, it is pepper in in the fly sh.t stuff but all is worth something in the end.

Pull your brake pads off and check them to see if they are worn on a skew. I checked mine with a vernier caliper and found they were worn on a skew. I ground them flat again with a right angle grinder. That stopped the dragging. If you are too heavy on the brake pedal it will wear the pads unevenly and they will drag like crazy. You have to be real easy on the pedal with light weight brakes.

I fought with Wilwoods for a couple years before throwing in the towel and ordering Lamb/brakes/spindles/struts. They were so pretty I wanted to sleep with them. 15 years later when we sold the car you could STILL spin the tire with over a minute of 'free wheeling". My first pass with Rodgers brakes, brake pedal, master cylinder set up I actually slid the tires after using what pedal pressure I had become used to with the Wilwoods. Those things are a real piece of engineering. It was worth it just for the ease on your back when pushing through the pits. Had to be careful on little grades as the car would roll into the ones close to you. We think the car was a hundreth or 2 faster, but how do you prove it......

A Very experienced NHRA tech man told me years ago that cars that run WAY under the index are very easy to push in the staging lanes. :):)

Dirk, Thanks for the reply. LOL, I like Pepper and Lots of it. When I get done with the Pepper shaker, my food looks black. The only way to tell whats on my plate is to send it out to a lab for DNA.
