I've gone through a few variations over the last year on my '87 SC to get a brake setup which can cope with regular track use.
First trackday ( Elvington ) was done with standard pads and disks - lots of fade toward the end of each session ( 10 - 15 mins ) and a very long pedal by the end of the day
2nd day ( Anglesey ) was done with grooved disks from WMS all round, EBC greenstuff on the front and standard pads on the rear. Also fitted Goodridge hoses and filled with DOT5.1 fluid. Still a little fade, especially at the hairpin ( 95mph down to 30ish )
3rd outing ( Anglsey again ) had swapped to Pagid pads all round. Much better with very little fade. Kept this setup for another day at Elvington, when mega fade set in during the latter half of the day. Turned out the front pads had almost worn out - after only 500 miles
Replaced the front pads with EBC Redstuff, and was amazed at how good they performed during two visits to Croft and another trip to Anglesey. An outing to Oulton Park finally finished them off, along with the Pagid rears.
Decided to try reverting to plain disks to try and reduce the wear rate - a day at Cadwell Park last Sunday showed that braking performance is unimpaired by losing the grooved disks, with no fade apparent from the Redstuff front pads and Greenstuff rears. Too early yet to assess wear rate though.
