Default 2008+ Perrin Master Cylinder Brace

http://www.perrinperformance.com/sub...8-brake-stiffi

I purchased this item over the Father's Day weekend because I had a coupon and it was on sale too. I had long been planning on buying the Grimmspeed part, but had decided to give the Perrin part a try. (I admit that I am partial to Perrin parts, they have always worked well for me. I know others aren't so pleased but I have had only good luck from all of their stuff.)

Install: You need little hands! (I don't have them) The instructions sent with the part were clear and easy to follow. I didn't jack up the car as they recommended but found that this was not an issue, I have long arms and was able to do everything I needed to do inside of the wheel well with the wheels turned fully to the right.

Unlike the Grimmspeed part, you actually remove some fuel line brackets and relocate the evap canister, but that is what the "stamped, powder coated steel piece is for. I think in their design process, this was/is used for fuel line support and location support of the main bracing piece which is a huge chunk of aluminum! I am certain it ads to some of the bracing ability of the part, but I feel the most substantial part is the aluminum brace.

Install took about 2.5 hours, to my defense, I did it alone at night with only a small florescent light and a flashlight. In the day time I think you could do it a bit faster. I also would recommend having on hand some metric hex bit sockets.







Impressions: To make this fair, I also have stainless steel braided brake lines from Technafit, but I think the immediate improvement of breaking response will be felt across the board. Pedal has been improved to nice and solid and all of the mush from the OEM system has been eliminated! Breaking response seems to have been improved as well. I think this was/is a good upgrade, and I think Perrin has done their homework on this design.

I would recommend this product!

Looks good man I saw the one about your pitch mount install. Would you recommend just doing both of them at the same time, or would it not make a difference?

Pitch mount is according to a friend of mine, "the best mod" he has done, for me it certainly reduced some of the drive train "slop" but increased the NVH a lot! I would recommend the pitch mount with bushings: subframe, crossmember, differential, and better transmission and engine mounts. With the MC brace, do stainless steel braided brake lines and better brake fluid, and maybe a pad with a bit more bite...

the perrin is a better design than grimmspeed...
is more direct bolt on from the looks of it.

Grimmspeed requires some moving around to fit it

Not to be a dick but, just because the Grimmspeed isn't a 100% bolt on the design, it's not as good or better than the perrin brace? Ill admit I did have to slightly move the fuel lines but its not like your doing heart surgery lol. If anything I feel like the Grimmspeed brace would be stiffer/stronger though since it bolts closer to the actual master cylinder on the side of the strut tower rather the front like Perrin does. Regardless it's evident that both of these do their job, and it's nice to have an alternate option.

Im just speaking in my point of view thats all.
But yes the grimmspeed might be more strudy compare to perrin.
Is just my situation, the perrin seems to be easier for me to put on.

I've had both (I had the Perrin in my 07 WRX), and the GrimmSpeed is more sturdy than the Perrin.

The Perrin.

I had to get under the car to add the final bolt to the GrimmSpeed brace. The brake line runs right over the bolt holes making install a bit more hard.

Thanks. The Grimmspeed brace is the only part that's beat me so far. Maybe I was having a bad day or something, but after a while I just said screw it and sold the part. Seemed like no matter what I did I couldn't hold the part in place and get the bolts where they needed to be. Didn't think about coming up from underneath though. I thought about taking the PW intercooler off to give me a bit more room, but the damn IC to throttle body hose is such a pain to secure. Thinking about giving the Perrin a try, but from what I can see it also bolts into some holes on the inner face of the shock tower.

If you are willing to drive to CT, I will show you how to install it easily.

Did you remove your intercooler?

No I did not. Because I have an STI, it took me a few to figure a good way to re-secure the fuel lines. The install on a WRX is easier.

It was easy for me on my STI. Fuel lines weren't too hard to re-secure. Removing the intercooler makes for an easier install. Just use a long extension, and then some trade secrets to attach the bolt to the socket. Get it started by hand first and then finish it off with a socket wrench. Easy peasy.

So after watching videos of Perrin and Grimmspeed, i decide to go with Grimmspeed.
i have a 2011 WRX with a Process West TMIC.
So to begin with i have way less room than the stock TMIC wrx came with.

I kind of got annoyed while watching the Perrin that the design is so much different and one of the perin guy said u have to jack up the driver side to get a bolt through, so i was like whatever i will go with Grimmspeed.

I just yank and pull on the fuel lines before i could fit that brace in, the first bolt was hard for me because i have to hold the brace and fit my hand to thread in the bolt.

But once that is in, the other ones are easy, the 2 lower short bolt is right next to the brake line, but mine had enough space for the bolt to sit flush on the strut tower wall.

I figure out a good tip to help thread the bolt in.
I used a 3/8 socket extension with a deep wall socket, i put the bolt in the socket and put a tape over the socket and bolt to keep it in place while i find my way to the hole and thread it in by the socket.

Oh yeah I saw the videos and I understood exactly what I was supposed to do. For some reason I just couldn't get my hands to do it. Seemed like not enough room and all the wrong angles. Not saying it's a bad design, just lamenting that it kicked my butt.

Yeah its pretty meticulous but if you do slightly move the brake lines over it can be done. I did it by myself but having a second person is always helpful regardless of brand.

i would most likely agree just by looking at each respective designs. looks like the Grimmspeed is 1 piece while perrin is 2 pieces. i am sure perrin's does it job beautifully as well.

I still like my Perrin one...The bracing itself seems to be done by a large machined part made of aluminum versus what is seen on direct observation in the engine bay...agreed, both do the job, both are good designs...

as to having to jack up the car to install, I didn't have to do that at all, I just turned my wheels sharply to make access easier.
