New ERA Project...

Not sure they are a big improvement but there are these GM caliper replacements for the front.

I think there may be some Sierra brake kits to step up even further for an increase in rotor size.

The Jag suspension works fine in most driving - I would think that the more you beef up the front brakes the less the rear brakes will be doing. But tucked in under there they don't get much cooling and they are running fairly thin, solid rotors. There are some ways to modify the rear brakes by installing spacers in the Girling calipers to fit a wider, vented rotor, but from memory it's fairly expensive.

Basically, if you are really going to run the car hard on a long track, you are going to need big brakes and the ERA suspension is the most straightforward way to accomplish that - but at considerable cost. If you end up going that direction then you might as well really open up the pocket book and get a 6-pin conversion for the front as I think most if not all ERA rear suspension have 6-pin hubs.

Post some pictures of the car when you get a chance.

As Dan says, if you are really planning on running hard on a track you probably want to go with the outboard brakes on the ERA custom suspension. Not only do they give you better stopping power, but also if you are driving hard you will be replacing rotors and pads more often and that is a LOT easier to do on the outboard brakes.

I did the standard to ERA outboard swap on #755 and big front brakes as well. All parts came from ERA. It was pricey.

The swap is pretty easy. Setting bearing preload on the hubs is a bit challenging, if you have never worked on a Jag rear. I'm sure ERA would do that for you if it concerns you.

I did recover some of the costs by selling the old ERA rear, front hubs and brakes to a guy that was building a new ERA.

As others have said the standard brakes are plenty large and designed for cars that weigh much more than your Cobra. The fancy ERA parts are for cool factor or racing.

Well, you can't put a price on the cool factor! I would wait on the rear end swap, see how I like the standard Jag unit over time, but the issue becomes getting 5 pin or 6pin FIA wheels...which I want to do ASAP. Anybody out there building an ERA? I got a rear end for you!
