    Another quality part from Perrin 1 year ago
    5out of 5stars

    I had recently upgraded my brake system with the StopTech sport kit and stainless steel brake lines. While these upgrades greatly increased the responsiveness and stopping power, the brake pedal still felt a little spongy due to the excessive movement of the master cylinder. This part definitely solved that problem. Pedal feel is firmer and inspires a lot of confidence in the brakes, even when braking hard. I chose the Perrin unit for a couple of reasons. The first one being that I already have a few Perrin parts on my car and have been nothing but satisfied with them. The second reason being that this particular brace is made out of one piece of solid billet aluminum, unlike the others that are multiple pieces welded together. And, of course, it's cheaper than the alternatives. As with every Perrin part, the instructions were very clear. Install wasn't difficult, probably took me about 15 minutes. 10/10 would recommend.
