Check out the master cylinder brace I made. I used the existing holes on the strut tower and the other end just rest on the strut tower to give some additional bracing. I like this route cause there is no drilling in the strut tower. Check out the short videos and you will see that there is definitely a need for a brace. It probably wont make much difference on the street but for the track, seems like a must.

Check out the pics and let me know what you think.

My thoughts - eventually the soft aluminum of the master Cylinder will be pierced from general vibrations and also being pushed against the steel bolt.

 

Definitely something I will keep an eye on. I might destroy an extra master cylinder I have laying around to see how much material there is at the end. I beat it is thicker than you think.

 

I bought one of the braces some time back off Ebay and tried it out. Noticed zero difference with or without it. Seems like something that would make a big difference but it really doesn't.

Without the brace you could see the master cylinder move in the engine bay with hard brake application, with it it stayed still. But, it just didn't really make any noticeable difference.

Yea I cant stop thinking why?? I see no need for this. Just because something doesnt stay totally in place does not mean something is wrong.

Props for thinking outside the box though and good work on a nice clean install. Dont think its hurting anything just dont see a real purpose.

 

As I mentioned, there probably isn't much of a need for it on the street. For the track, I figure it will offer a little more firmness of the pedal and possibly more pedal feedback. The thing is probably flexing 1/4"-3/8" under hard braking, that is a lot IMO. It definitely makes the pedal feel stiffer.

 

It definitely makes a difference... if you did the mod and you didn't see a difference, then i suggest that you flush your brake fluid and replace with a hi-quality brake fluid, swap out the rubber hoses for steel braided lines and put on quality brake pads

 

I've done this mod, have had it for about 2 months and it does work (and very well) but I didn't use a bolt to put pressure on the MC. If you have done it and you haven't felt a difference, then...your doing it wrong.

Also if you want to be balla, you can always buy the over priced cusco version.

Does that work on LHD cars?

 

^ I have no idea. Best bet would be to contact RHDJapan.com and ask them.
