1″ Master Cylinder Brace



Designed to work with our 1" master cylinder upgrade kits. This brace eliminates firewall flex. It supports the end of the master cylinder and is braced from the stiff upper shock mounts. Under braking, the firewall will flex, allowing the booster and master cylinder to move. This flex makes modulation under hard braking difficult and inconstant pedal feel. The brace will reduce travel and offer a firm, constant pedal lap after lap. Powder coated in silver vain gray.

Adjustable to fit different size booster, both NA and NB, with our Master Cylinder Upgrade Kit.

Perfect upgrade

Perfect fitting upgrade for my ‘90 NA with the wilwood 1in master. Bolted right in, easily adjustable to tighten up to the master. Build quality is excellent. Was a perfect upgrade!

Does the trick

I run this on my 2JZ Powered NB racecar. Fits under the intake perfectly and mates up to the Wilwood MC. I was having soft pedal issues, I know this helped it.

Perfect Fit

Had a brace on my OEM master and thought I’d try the wilwoods master as is. I noticed the pedal feel about equal but saw the firewall flex almost half an inch. This brace fit perfectly and made the brakes perfect! Easy to modulate and confidence inspiring.

Perfect Fitment

I ordered this brace because I upgraded to the Wilwood duel master cylinder. When I had my stock master cylinder I had a brace on that and love how it felt. This one is bigger and modular, after dialing the it in, the feel on my brake pedal is consistent and stiff. Great product!
