As per an earlier post AP used to (and may still) make a big brake kit that
is designed to fit under the 8" Ronals.
I enquired about them with one of the local dealers a few years back and
they were still available. These are the ones that Dave Eaton put on his
real 20v UrQ, and was really happy. Should still be in the archives.
They did however disqualify themselves on the basis of cost.
My experience with the SQ fronts was very positive on the track although it
is essential to adjust the bias. The 200 conversion to the rears also
really helps balance things. I would not recommend them for street use
based on my experience, but this could be a function of inappropriate pads
(Pagid orange). The rotors are also extremely heavy. I will be trying to
find one of the ECS products as a substitute in the coming months.
At risk of stating what you all already know, choice of pad material makes a
huge difference, both on track and road. Track pads on the road are a real
formula for problems (Duh).

>> The question for many is what will work with 15" rims?

>> If that is not a question, then the A4 line

>>
>> First they can use A4 calipers with TT brackets

>> urq.
>>
>> Boxster over A8 is next upgrade, or ECS special rotors.
>>
>> There are so many A4 brake upgrades...take your pick;
>> from 25mm to 32 mm thickness, and from 276? to 314 or larger
>> rotor sizes, just depends on how much wheel you will stuff

>>
>> Brembo or Stoptech are the ultimate front brake, but will require

>> 16" rims.
>>
>> You mentioned rear 200/urS4 rears. Be careful here.
>> 200 rotors have a different offset (hat dimension) than
