Paul,

The Skyline calipers are not perfect as they do not have a very large pad area, also no external balance tubes or any decent strengthing type ribs or material to stiffen them up. But my brother runs them on his Cobra with 300mm rotors and they are more than capable for regular track work. Enough in fact to win multiple Cobra Nationals with. But you have to use the right pads and rotors. Skyline calipers are great value.

With Wilwoods you have to pick the right caliper for the right application. If you are going to do track work, you would be using the larger calipers, SL6, SL4, GNIII. I wouldn't be using Dynalites for the track in a Cobra. Personally I'm a huge fan of Wilwood calipers, very capable and very good design. My GNIII's have external balance tubes, significant strengthing ribs and a nice pad area. Wilwoods are used by some very big players, they are very capable for track use if sized right.

AP racing, Cameron uses AP calipers front & rear on his Superformance. I think his rotors must be around the 280mm size, similiar to your Jag ones. He runs 15" wheels. Maybe he can chime in, if he remembers which model calipers he is using.

With any of these calipers you will need to find someone to make the adaptor brackets for you and confirm the calipers will fit. Or find an aftermarket kit that will fit, but run the risk of complications in your particular Cobra setup.

With your current setup, you could just swap to better pads for track, maybe better fluid, maybe better rotors and see some significant gains for track use. It might mean, swapping in pads just for track use. Have you got some professional advice in this area for your existing setup?
