Jag big front brake conversion

I knew you'd over engineer Mike, it's just that fleeting thought as you dive into that nice right hander on the GOR for example, with the sheer cliff on the left......

These sort of questions go through my mind every time I look at some part of the car. With my rear arms I'm thinking about what tha fatigue life of the 4130 tube is going to be like? Will the welds become brittle and crack eventually? Are the rod ends I've chosen strong enough? The things that give me confidence is looking at cars already on the road (especially production cars) and the types of components they are using. Take what they have and add a bit of over engineering to be safe.

I was comforted after seeing the arms used in the MoTec Daytonas and see that I'd used larger diameter tube with a thicker wall and larger rod ends. As a car with similar weight and performance to our Cobras I figured I'm probably on the right track.

It's not really feasable for us to do the level of testing a big auto company would do but we can use some sound engineering principles when designing a part. A bit of over engineering doesn't hurt either especially if you aren't chasing every gram of weight.

Cheers
