Thanks guys.

So to narrow it down for discussion purposes, lets say I plan on using 7x16 front and 8x16 rear Fuchs.

Now, I admit not doing or even venturing a guess as to how to do the math, but I wonder if stock calipers and rotors, with judicious use of venting, would have trouble keeping up with a car 200+ kgs lighter than new? The car will not run slicks, but r888's or similar and the longest track stints will likely not exceed 20 minutes.

So I guess I'm saying I'd still like to see what options are out there that are lighter than the stock ATE anchors, fit under 16" fuchs, fit or can be adapted to fit Bilstein struts and fit or can be adapted to fit stock or carrera rotors or aftermarket alternatives.
