Default Master Cylinder Brace

Is this a decent upgrade? will it make a noticeable difference in brake feel? Or should i just make my own?

Brake "feel" is greatly improved and it certainly helps to modulate the brakes if you disable the ABS while tracking. I wouldn't really advise making your own as there are some interesting fitment issues you will encounter already. People have their own preferences as far as brands go but the more attachment points the brace has and the stiffer the material the better. I would take a 3 point steel unit over a 2 point aluminum one if you get my meaning.

The Cusco one I just installed uses four bolts to attach to the side of strut tower. I already have Stoptech fixed calipers with stainless lines and the brace made a noticeable improvement to brake feel, but don't expect any performance benefits. This mod really depends on the preference of the driver, so people with brake fetishes will definitely think it's worth it. Install took less than 30 minutes. Don't waste any time messing with the bracket that holds the battery cable; remove it 'cause it won't fit with the Cusco brace.

Very noticable upgrade, (unlike braided brake lines which didn;t seem to make any difference.)

I got the Perrin one. Not a huge fan of Perrin products, but the Perin MCB is certainly the nicest one out there in terms of looks,..and at $60-65 is less than 1/2 the price of the Cusco one.

There are 3 bolts that hold the Perrin brace to the strut tower,..I suggest a big washer or a short length of angle iron to help spread out the force on the rear-most bolt.

One of the members over on rs25 made some up for us GC boys. It stiffened up the brake pedal and made it "feel" much nicer. It's much easier to modulate the pedal during mid-corner adjustments now too. Worthwhile upgrade IMO.

I will also note the level of flex you experience from the firewall is directly correlated to the brake pedal effort you must physically exert to slow/stop the car. From this idea, we can see that using a grippier brake pad will require less pedal effort and have less sidewall flex. Less pedal effort also means less line pressure and less need/influence by steel lines vs oem. I would assume there is also less strain/wear on the entire brake system as well.

This is something to think about when deciding which upgrades you might want to opt for.

I will also say that you get improved braking feel from suspension bushings as well. Well, you just get better feel from the road overall. This correlates to better feel of the tire and feel for the the braking is actually doing. Plus, it will get rid of some of the suspension twist/flex associated with braking forces, so the braking force is more quickly and efficiently used.

This can also be applied to suspension, dampening, and the physical dynamic behavior of the car. If the car is stiffer and with less roll, braking and steering actions will occur more quickly and more precisely. With the very soft stock suspension, you get a lot of physical dive associated with the car. In this sense, you're braking but the car doesn't stop right away. It has to travel through this full range of movement until suspension compresses enough. This slow and ungangly process is also existent during small modulation of the brakes, making everything more delayed, vague, and less precise. So, bushings squish AND the car twists and bobs around to your inputs making everything a sloppy mess.

Again some things to think about...

I can't say anything specific about the master cylinder brace as I don't own one. I may in the future at some point, but I have opted for the above mentions for various reasons and have found positive results when correlating their influences towards braking as well as braking feel.

I'll say many people, well probably most everyone who's installed a MC brace seems to say they work very well and is a "noticeable" upgrade, unlike the mixed results from the brake lines. In this sense, it's more of a sure thing.

I'll say this - we use them. We like them. And we don't even sell them.

Will that work for folks?

I wish Tom, Clint, Tony, Myles, and Shane made all the goodies we needed for our Scoobs, then I wouldn't have to deal with all the asshats that just sell parts and can't answer my tech questions.

Well i just bought the Perrin Brace, They failed to mention the fitment problems when i purchased the brace. I have to remove the fuel filter rentention bracket to install the brace, they told me to just install an inline fuel filter and ditch the OEM one. Anyone done this? Will just ANY inline due? Im hesitant to switch the fuel filter to an inline one. Anyone have advice on what to do?

I've tracked a lot of Subarus with all the aforementioned braces.

The CUSCO piece is my personal preference because it really does
offer the best pedal feel when you are hard on the brakes (i.e. if
you prefer ABS ENABLED).

If you go NO ABS... not much difference in feel between the braces.

And yes, Myles, Clint and Tom ought to get into the Mcly brace
business... they actually understand the difference between
functionality and bling-BS.

but i read that the cusco doesn't fit the 2.5i's...

would the perrin "fitment" issue be a problem with an rs?

Cusco piece ftw! nice secure mounting.

Or you can get a carbing strut bar that has a integrated master cylinder brace.

Not a fan of theirs as I don't think it does a think. I have seen it in place before and was able to move the brace with my hand. Definitely not going to keep the NM from moving.

where would be the cheapest place to buy a cusco brace? does it get any cheaper than $85. I'm replacing my rotors/pads/and lines so i'm thinking of installing a brace while i'm at it.

If you get the Perrin, use a bigger washer on the rear bolt to spread the forces over more area to reduce flex. I have no experience with the other ones.

Umm...it isn't doing anything. The Cusco brace completely stops the MC from moving.

Agreed. I've had this discussion before, but I haven't seen video evidence that any cause less flex. (I'm a see-it-to-believe-it kind of guy).
