I'll put up more info on here as I find out more myself as I continue to research this to death.


Cobra Calipers should be seperated into 2 groups. (94-98 and 99-04).

Dimension wise they are the same. The difference between them is simply the size of the pistons.

Cobra 94-98 = 38mm Pistons
Cobra 99-04 = 40mm Pistons.

Here's a quick link to one example:

So it looks like either will work, just a minor change in piston size.
