Well.. on stock 156/147's, when you upgrade the 284mm system to 305's all they recommend is an upgrade of pads for the rear..

On my TS, I got Ferodo ds2500 on the stock rear calipers, and some crappy red dot pads on the 305 brembo front.. ive found that on full braking and when the brakes are well heated(talking trackdriving here)
then the car becomes twitchy!. Feels very unsafe actually..! This problem springs from the back brakes having too much power.

I would have thought the ABS system would compensate for something like this. but it sure feels like it is not doing a proper job!

Under normal driving conditions, the car feels well balanced, but, as the brakes heat up, the Ferodo works better and better compared to the Red Dot pads, and as a result it becomes twitchy. Untill i get my Ferodo pads for the front, my car is actually very limited on the track.. Amazing how big a difference a set of pads can do!

So like you say Trailbraker.. you really need to think about how you set up the distribution front to rear!
