Rear brakes

[Markh]

I need to replace the rear discs on my 99 Chimaera and was wondering if there is an upgrade available , I have 305-mm AP discs and calipers on the front, the rears are standard size but drilled and grooved but are scored on the inside, was looking at some Cosworth units with 4 calipers ,was thinking of getting discs with separate bells (need these as I would like to fit motion sensors for my traction control set up), was also looking at fitting a brake bias control at the same time, any thoughts?

I believe there is very little choice when changing/upgrading rear callipers if you want to keep the existing hand brake arrangement. I recall TVR Car Parts were looking into it a few years ago so it may be worth calling them - I've seen a HiSpec one in their reception. HTH.
