Stiffens brake feel
pr0file 3 months ago
Bought this cause of the issues, in some cars, that arose through heavy braking. It improves the feeling of the brake and it feels more solid when depressing the brake pedal.

2016 Hyper Blue STI
HyperBlueSTI 2 years ago
Ordered this piece from RSD and installed it in under 30mins or so. STI has fuel lines I believe along the driver side where the master cylinder brace is. Made it a pain to maneuver my hands around, but there were absolutely no fitment issues on the 2016 Limited Series Hyper Blue STI. Cusco paints this piece in their signature blue color and it definitely catches your eye in the engine bay. Drove around some after the install and it helps a tad bit. I think combined with stainless brake lines the brakes on the STI would probably be a decent setup. I do recommend this product and RallySport Direct is there to help every step of the way.

2014 Subaru XV Crosstrek is COMPATIBLE with this part, SIGNIFICANT BRAKE PEDAL IMPROVEMENT
AWDfreak 3 years ago
Installation was not too difficult. The immediate improvement was as dramatic as installing stainless steel braided brake hose. It's a night and day difference that helps reduce the firewall (now called a bulkhead) flex that's common amongst newer Subaru models, not just the WRX and WRX STI. I would highly recommend this to those who wish for their brake pedal to be stiffer. This mod will probably apply to GJ-chassis and GP-chassis Imprezas as well as GP-chassis XV Crosstreks and of course the confirmed fitment of the VA-chassis WRX and WRX STI models.

A welcomed addition, but not a must have part.

Build quality is outstanding and sturdy. Install was straight forward but a bit meticulous on my WRX as a couple of the bolts were tough to reach with my big hands and arms. Slow turns on a 10mm closed box wrench were required which took some time. Install instructions are all in Japanese, so watching YouTube videos is recommended. This ended up firming up the pedal at the bottom of its travel. There is still a small length at the top of the pedal's travel that still resides, but I can definitely tell this part is working as intended. Snugging down the bolt against the master cylinder only required about 1/2-3/4 turn after the initial contact. I didn't want to wrench it down too much, as the cylinder is only aluminum.
