Big Brake Kit
Hi, I am working on a Gen 1 RX7 and couldn't find any big brake kits so I made my own with some help from Wilwood. Machined down the stock rotors on my lathe to hold the new 300mm Directional vane rotors. The conversion was actually pretty easy. Haven't had it on the track yet but hoping it works well.
Thought I would share some pictures. https://cimg7.ibsrv.net/gimg/www.rx7...1f3aba2108.jpg New Vs Old https://cimg0.ibsrv.net/gimg/www.rx7...6c9ef551f8.jpg Used the stock rotor and machined it down on my lathe to accept the new 300mm rotor https://cimg1.ibsrv.net/gimg/www.rx7...ee6553284a.jpg The conversion was actually fairly easy. https://cimg2.ibsrv.net/gimg/www.rx7...402e85fef3.jpg |
Nice work!
|
Nice , any problems with a pulsation or shimmy from balancing issues. What calipers did you order
|
As I mentioned above I have not hit the track with the new brake system yet. Really don't foresee any balance or pulsation issues but you never know. The rotors are Wilwood GT36 series curved vane design.

The new 15" x 7" wheels just clear the caliper.

I really like the look of this!
|
Did you have to make a bracket for the caliper to bolt up.I'm interested in this set up:)
|
Yes, I did fab a steel bracket that the caliper mounts to.
It turned out really good. The true test will be at he track the last weekend of January. :nod: |

Good stuff man! Looks awesome.

I thought about doing that too. But had decided that being a casted metal (seeing a few rotors come apart) it may not hold up. Then found that KC Raceware makes aluminum hubs and a brake kit.
7's Only ( Home )makes a couple different brake set ups too. Along with A Strut with bigger tubing for a real shock. I have the 7's only Strut/brake on my car. I ran a smaller rotor so I could use 13in wheels. I know this is a little late. But you did a great job on it. Looks like it should work. |

What group are you racing with?
|
I will be racing in the STL class in the SCCA Major series. Hoping to qualify for the runoffs at Mid Ohio in September. Doesn't look like I will be ready for the first race at Auto Club Speedway with the RX7. I will be there helping my son who will be racing in the Formula Vee class. Hopefully I can get in a test day before round 2 at Willow Springs in mid February.

Wow this is really cool! Also interested in which wilwood caliper you chose! Looking forward to news on any balancing issues, which is also the first thing that came to my mind. Nice work man.
|
Thanks for the nice comments. The folks at Wilwood were really helpful with the engineering on the correct combination of components.
The rotor is factory balanced so I don't foresee any issues like that. Could be others though..... just have to wait and see. |
