MX-5 ND Stoptech STR-40

Post by MaximeP725 »

Hello!
Here is my first publication. I'm quite proud of my little project. Over the last 10 years I have built a few racing cars and I have always used stoptech ST series brakes. They are very efficient, robust, durable and I have total confidence in these brakes. I was a little disappointed that stoptech didn't make a set for NDs. I then designed brackets and hats in order to install STR-40 with 328x28 Girodisc floating rotor on my car. Bracket are made of 7075-T6 and hats of 6061-T6. All components have been tested under FEA simulation. For those worried by the red color of the analysis, I used in my calculation that 150% of the total weight of the vehicle braked on a single wheel while shortening the braking distance by 25%. This version is the final prototype. The only remaining upgrade will be aesthetic (machining finish and anodizing). Very open to your comments!
Thanks!
