Cusco Brake Cylinder Stopper Subaru WRX / STI 2015-2021 | 6A1 561 ALHD

One thing I didn't love was the inherent sponginess of the brake feel, this brace helps take the flex out of the master cylinder and def firmed up the feel. Build quality up to Cusco standards, would def recommend

Nice Cusco upgrade

Super quick instal and instant difference in stopping power!

I order the CUSCO BCS for my 18 FXT and I must say I noticed the difference right away just by driving my kids to daycare. The brake pedal feels nice and firm, unlike the way it comes from the factory. I recommend this item to anyone that hates the way the brake pedal feels.

The Cusco support brace was exactly what I was looking for. Bolts up easily with 5 supplied bolts to existing holes. The color matches WRB cars spot on. The instructions are in Japanese so they are useless but I did see you want 30mm between set nut and the pressure red stopper from brace to master cylinder about 1 3/16" length. The pedal feels so much more stable now. When you press the pedal the brakes don't have the "sponge" feel any longer. A much better feel of no movement. This is a small but awesome upgrade that you can feel forsure. Under 100 bones for an easy install and upgrade is a no brain purchase. I would recommend to anyone looking for better brake feel and response.

Cusco makes quality parts we know this big getting it the next day or 2 later with free shipping is the game changer and this is really the only place that can get it to you that fast just make sure you get the right part bc ships set do fast by the time you call and let them know your setting up a return bc the vendor shipped it already lol

First time buying a Cusco product and I’m impressed by the overall fit and finish of this brace. Installation was straight forward and took 20 minutes. Brace color matches my car which is cool I suppose. Post installation, braking feels much more responsive and immediate when initially depressing brake pedal. Nice upgrade!

Good fitment and definitely does what it's intended for. One thing to note is that the lower bolt that mounts to the frame will be quite tricky unless you have small hands. Other than that great product!

First off the price is great, the shipping was fast. Best customer service there is! The brace fit perfectly and took only minutes to install with the included hardware. Great fit and finish.
