Ordered a Marks 4WD hydrobooster kit yesterday.
Earlier in the year I did the DBA slotted rotors, new master cylinder (same as 4.8) and all stainless braided lines to go with the ECB Yellowstuff pads I already had but I was a bit underwhelmed by the result.
I didn't want to go the bigger rotors/calipers route with bigger rims, etc
