I believe that the Ferodo DS-11 pads are no longer available new, and
Joe Alexander has acquired rights to all old pads.
We have been using the Hawk Blue compound. They work just fine but must
be warm so I warm them up on each pace lap. They are pretty aggressive
and do wear the rotors. They also shed a compound / metal dust that, if
left on the wheels after it rains, is nearly impossible to remove.
Because of the above disadvantages, we are going to try the Carbon
Kevlar linings for both front and rear that are supplied by Ted
Schumacher (TSI Automotive) at the next change.
By the way, I don't find front pads listed in anybody's catalogs for
TR4's. They are nearly identical to Datsun 240Z's, however, which are
listed. We always have to grind just a little bit off the ends of the
pads so they slide in the calipers properly.
