Mines still CVH and it is a bundle of fun, The standard brakes don't really cut the mustard though, and if you plan on upgrading do this first, I have gone down the Sierra 4x4 route with TAROX disks and changed the pistons to stainless!

I warped the standard cosworth 4x4 disks round castle donington and I found the original pistons rusted then got sticky so making this likely to happen again, stainless = no rust = no sticking.

I would also look at track day tyres too for the front!
