bloody f1.8 prime lenses and their soft focus really irks me!!!
ANyway 4 pots on the back are for show rather than go most of the case
S3 calipers are all that you actually NEED combined with a decent ttrs setup up front
340/345mm on a ttrs caliper with the aks adaptors and whatever the s3 is (i forget is it 303 or 310 or 308 blah blah) will give you a lovely pedal and good even braking force which will hunker the car down into the ground.
Issue is after this master cylinder and long pedal
you'll need 6/8 pots up front to compliment a 4 pot rear. That's a lot of fluid
and a lot of cost
Once you go above the ttrs / s3 - front / rear setup the improvement tails off very quickly at great expense for that extra 5%.
even for most people on the track or in light competitions its not necessary.
notice how nearly all of the multi piston rear setups are on show cars that never go more than 30...
