The PERRIN Subaru WRX and STI Master Cylinder Brace prevents unwanted movement of the master cylinder, allowing for increased brake pedal stiffness.

The PERRIN Master Cylinder Brace significantly reduces flex at the firewall, so you get solid brake pedal feel with every application of the brakes. This is very noticeable while under heavy braking and even slowing for a stop sign. The difference can immediately be felt after installation.

Your brake pedal is connected to the thin sheet metal firewall which flexes as you apply the brakes. The firewall is not stiff enough to deal with the constant and repeated forces while applying the brakes. The PERRIN Master Cylinder Brace creates a bridge between the firewall, master cylinder, and shock tower, significantly reducing flex in the firewall while braking.

When possible we try to design Master Cylinder Braces in one piece to improve rigidity. The PERRIN Performance Master Cylinder Brace for the 2015 WRX/STI is CNC machined from a large piece of 6061-T6 billet aluminum for extreme stiffness. With stainless steel hardware and an anodized finish, the PERRIN Master Cylinder Brace will look great and last the life of the car, even in the harshest conditions.

The PERRIN Master Cylinder Brace is design to attach strategically to multiple points on the shock tower. This helps reduce flex in the brake master cylider by creating a solid connection between it and the chassis. To further aid in stiffening or tightening up this connection, included is an adjustable screw that allows tension to be preloaded on the master cylinder.

Comfy and supportive
Love it! Very snug and supportive. I am 5‘6“ 188 pounds. I am wearing a 34H and it fits perfect. Will definitely be adding more colors to my collection. Hopefully they add the HSIA Delia collection that are similar to these, but have printed options.

Very Good strong material
I love the bra but story time, I initially got a 38DDDwhich is or was my size however I wore the 38DDD all day at work (RN) and the bra did hurt my sides like the sides were possibly too tight and digging into my ribs BUT the support was amazing and the minimizing was PERFECT I looked almost 2 cups sizes smaller in my opinion but I figured something was off so I ordered a 40DDD got those and the side digging wasn’t there but I lost a little bit of support maybe or I could have just done the straps wrong because it was a quick try on but overall I love the slimming effect and the material is soft and I truly appreciate this bra. The material is STRONG not cheaply made very beautiful over all. This is a good quality bra once I figure out the correct size . I ordered another 38G to see if I noticed a difference and a 40G to see if my cup size is wrong all together (which is what I think it is more so than the band size) I tried another brand and the 38 band was find the cup was too small in 3 different brands. Guess I’ve gained some weight but overall even with the pain for the side digging I could tell this was a GREAT bra. Just measure yourself correctly lol
