Someone call?
Yes I have the 16" AP Racing brakes on my car. Here are a few of my thoughts:-
Peformance - they stop the car very well although I must state I have never driven an Elan with standard brakes so cant really quantify in terms of improvement over standard. I have owned previous cars with 4 pot set ups such as Brembo's etc. and these compare in braking ability on the road but havent tested them to extreme on a track.

Maintenance - while they might not need as regular fettling as the standard set up they are not fit and forget. The car had been stored in a dealers warehouse for some time before I bought it and there was some imbalance, I possibly could have got away with just changing the seals but got them fully rebuilt with new pistons & seals.
Costs - expensive to buy new but were already fitted when I bought mine. Parts also expensive, I had to fit a new disc when I first got it as the dealer only fitted 1 new one to get it through the MOT, price was around £220 per disc.

Would I buy again - Used - If already fitted to the car, yes I would be happy to buy a car with these fitted and refurbish if necessary. New - If replacing standard brakes on a car would probably go down the Hi Spec/PNM route as a more cost effective upgrade with very little difference (if any) in performance.
Hope this is of some use.
