What's the advantage of using the GKTech brake master cylinder stopper?
This small but effective stopper ensures there is no flex in the firewall, which is super noticeable under hard braking.
What modifications are required, is this hard to fit?
No modifications at all, the bracket simply bolts up to the OEM M6 holes in front of the master cylinder.
Is there anything else needed for installation?
No, the kit does come with all accessories and will arrive as shown in the product photo.
Can I install this myself? If so how long will installation take?
Yes, you can. This is a super easy and effective install, which should take around 15 minutes.
I'm running a bigger brake master, will this still fit?
Yes, the brake master cylinder stopper will fit providing that you're still running the standard brake booster.
Does the firewall really flex that much?
Yep, it sure does. It's actually very noticeable under hard braking conditions. The brake master cylinder stopper truly does make a difference and is one of the good value for money mods.
NOTE: #2: Will NOT fit with the standard KA24 EGR equipment in place

Install was a breeze, brake feels great. I’ve always seen these items floating around the market and always thought it was a gimmick. Boy was I wrong. If you’re on the fence about it, just do it. My brakes feel 80% better!
One of the most over looked upgrades when you drive your car hard, I road race and this definitely helped achieve a more solid pedal!
5 minute install. Eliminates all firewall flex.
