Thanks for the ideas from all of you. The issue of a longer push rod =
(which I have, 4.5 inches) is that you can only go up against the throw =
out bearing just so far. Right now I=E2=80=99m touching the bearing =
(which I don=E2=80=99t want of course). Today I received my order from =
S.S. (new kits for the master and slave) and it seems to have improved =
the issue, I=E2=80=99ll try driving the car tomorrow to see if it=E2=80=99=
s livable. I let someone talk me into a RAM clutch, should have gone =
with a Centerforce maybe? Rick from S. S. said people have had good =
luck with them. I=E2=80=99m now of the feeling if you aren=E2=80=99t =
racing, a standard Mustang clutch is more than enough for the Tiger. =
The idea of a higher volume (larger dia.) master also suggested by Rick, =
is that it will make the peddle force higher. Another issue is how far =
can one allow the slave piston to travel without coming out of the =
cylinder (mine does not have the retaining clip like it shoes in the =
manual). Mine has a max movement of around 1.350, The piston could come =
out another .300 ,but that would have the front of the piston .300 past =
the end of the cylinder, probably not a good thing!
Thanks again for your responses! Jerry
