Z1 Motorsports 350Z / G35 Brake Master Cylinder Brace

starstarstarstarstar_half 4.9/5 - (46 Reviews)
Fits models: 350Z / G35...

Product Description

Z1 Motorsports Brake Master Cylinder Brace is the premier and most affordable brake upgrade you can buy for your 350Z, G35 Coupe, or G35 Sedan. It is effective for Z's and G's either on the track or in traffic.  Increase brake response and driver confidence with this elegant mod.

When pressing the brake pedal, the force applied is transferred through the pedal assembly and unto the firewall. Although reinforced, the firewall is still easily manipulated. Z1's Brake Master Cylinder Brace provides a halt to this flex by securing the Master Cylinder against a series of solid aluminum brackets fastened through the false firewall and directly to the driver side strut tower.

If you are not convinced of the need for such an accessory, grab a friend and pop the hood or your Z or G. Remove any covers around your brake Master Cylinder. Have your friend sit in the driver's seat and press hard on the brake pedal a few times. Watch the Master Cylinder move towards the front of the car with each press of the pedal.

Unlike similar products, Z1's Brake Master Cylinder Brace is a simple bolt-on solution (no machining required!) and eliminates ALL of the firewall flex, giving you the quickest reaction time from when you press the brake pedal to when pressure is applied to the rotors. Couple this brace with high temperature fluid, braided stainless brake lines, upgraded pads, and rotors, as found in Z1's Brake Upgrade Packages, and completely transform your braking experience.

 

Features:

  • CNC Machined Billet Aluminum Black Hard Anodized Base
  • Precision Investment Cast Aluminum Black Stopper Arm
  • Yellow Zinc Coated Custom Hardware
  • Integrated Clutch Master Cylinder Reservoir Mount
  • Installs in less than 30 minutes!
  • Detailed Installation Instructions

As you can see from the installed picture, the bracket fitting the clutch reservoir has been eliminated and replaced by the cast aluminum arm. Z1 includes all of the necessary hardware to mount your reservoir to this arm.

Note #1: Since the 2007+ G35 Sedan shares the same body as the G37 Sedan this Master Cylinder Brace does not fit. For those with '07-'08 G35 Sedans, please take a look at our G37 Master Cylinder Brace.   

Note #2: This brace can NOT be used with any aftermarket strut mounted chassis brace.

Bought to replace a competitor's product. The other product was in interference with the top mount adjustement of the front coilovers and had to be modified. Great product and no more interference.

Noticeable improvement in braking feel and power with the master cylinder brace. Machining is high quality and looks great under the hood. I first used it for a few months with stock G35 brakes, base model, and could feel a nice improvement. I later upgraded to the Z1 stainless lines and the performance of the Z1 combo is superb. Glad I got these!

Superb product quality and fit. Like factory. Made a definite difference in the brake feel. This, combined with stainless steel brake lines and MOTUL DOT 5.1 brake fluid, help tremendously in improving the feel and responsiveness on the track to the point that the tires become the limiting factor in your confidence. The instructions are good, but it pays to read and reread them a dozen times while watching videos on youtube and then closely examining under the hood and test fitting. But when it's on, it looks like something Nissan installed.

IF YOU LIVE BY, "IT'S THE LITTLE THINGS IN LIFE" THEN THIS IS THE ONE FOR YOU! I HAVE A 2004 G35 AND APEX EVERYTHING IN IT AND I LOVE THIS SIMPLE TO INSTALL UPGRADE. MY BRAKING COMMUNICATION IS NIGHT AND DAY FROM WHERE IT WAS BEFORE. THE VEHICLE IS ALSO EQUIPPED WITH Z1 2 PIECE ROTORS FRONT AND REAR AND HAWK 5.0 PADS BEING SQUEEZED BY OEM BREMBO CALIPERS. THE Z1 MASTER CYLINDER BRACE WAS THE MISSING LINK. THIS IS A FANTASTIC LITTLE BIT OF ENGINEERING. THANKS Z1!!!!!

Didn’t really believe it would make a difference, my buddy convinced me to get it and I was not disappointed. You could actually see the firewall move before installing the brace and it not move after installing it. It is a noticeable difference under hard breaking.

This brace definitely changes the brake pedal feel for the better. My only complaint is I had to source some new hose to make the clutch reservoir fit the angle of the brace mounting point. I believe it's because I have a wildwood master cylinder but I can't confirm that.

Simple, cheap, does what it says it does, helps give more pedal feedback. Simple upgrade and makes a large difference with the 35th Anniversary edition Brembo brakes we have the car. Don't over look getting things that help bring out the 350Z's true personality.

This made a noticeable different on a 2004 350z, base model. Firmed up the brake pedal and got rid of some of that "sponginess". I had someone sit inside and press the brake pedal with and without this brace installed, and the false firewall doesn't flex at all now. Thanks Z1 _3

Brace is strong and made well, and it makes the pedal feel better. Didn’t give it a 5 because the brace touches some of the hard lines and due to that I can’t get my clutch reservoir perfectly vertical. I’ll have to grind it down or cut some of it away to get it to fit without rubbing the lines.

This part really makes the brake system solid. It's made with high quality, removes the soft pedal feel, and it's much easier to heel toe and brake without applying too much brake. With a big brake kit, this piece will truely benefit the brakes even more!

Finally had an opportunity to install the brace before the Ultimate Track Car Challenge at VIR this weekend. It really is a big a help in firming up the notoriously vague brake pedal in these cars. No more feeling the need to jam your foot through the firewall. I'm very impressed with how such a simple piece can make a substantial difference in overall feel and confidence. Highly recommend for street and track cars alike.

There is no single word that can describe how great this brace is. Upon un-boxing initial inspection reveals a very well machine and packaged brace, with beautiful gold zinc plated hardware neatly packaged in box. This brace comes un-assembled in box with install instructions, however the simplicity of the install meant I did not have to look at the instructions once. This was completed with basic tools in under 10 minutes and didn't interfere with the stock strut tower brace. I participated in the Santa Run at AMP this last Sunday for my first track day in my '07 Touring with nothing but base 06+ brakes, Motul 5.1 fluid, and Hawk HPS pads and it was felt great, but the brace was just icing on the cake. I ran one session with the brace loose to see how the car felt on the track with/without to compare the pedal feel and it was a night and day difference. With the brace tight I gained an unshakable confidence in my brakes. The pedal was quite a bit firmer, especially under hard braking allowing me to brake later and gain higher exit speeds at the same time! I improved 5 seconds between the two sessions under the same variables with no cars ahead. I even found myself out-braking C5 Corvettes, S2000's, and BMW M3's after settling into my car. After 5 sessions I checked the brace adjustments to verify everything was tight and didn't have to put any tools on the car. This brace is a MUST HAVE for track cars, and an added bonus for street and daily driven cars! I can't wait to see how this performs with Brembo's and Z1 2-piece rotors when that finally comes along.

First off let me get started by saying that: 1) the install takes literally 15 minutes!! 2) I honestly think you can run just about any strut tower brace. It clears the greedy bar and the stock bar!! Installation was a breeze. All you need is (2) 10mm wrenches 19 mm socket and a 12mm socket 6 inch extension and a ratchet. Comes with instructions but didn't even need them that's how easy it is. Performance: night and day omg! This mod right here goes fanfreakingtastic with my akebonos and SS braided lines!! I recommend everyone to buy this kit. I impulse bought this during Black Friday.... Best idea of my life :D

The last piece of the puzzle when upgrading your brake system. This brace was installed on my 2007 Nismo 350z w/ ARC strut bar and I had zero issues with fitment. In my opinion this is a great upgrade for both street and track applications. With A++ build quality & clear and concise install instructions I couldn't be happier with my purchase. Hats off to the Z1 team for creating another great product!
