<<... moving along (too slowly) in my resto project, I'm looking at the
various clutches used in the TR4: the original style (9", I believe)
which I currently have in the car, and the later TR4A diaphragm type
(8.5") which the competition prep manual recommends as an upgrade. Is it
worth it? Also, of the latter there are two manufacturers commonly
available: Laycock and Borg & Beck. The Laycock is somewhat more
expensive.
Any preferences out there? I would appreciate any feedback, good or bad,
on any of the 3 possibilities (or others), in theTR4 or other models.
When completed, this car should be 150 to 160 hp, 4.1:1 or 4.3:1 rear
end. It will see some "vintage" track time, but mostly for fun on the
twisty, windy 2 lane backroads in the N. Calif. sunshine.

Hi Alan
I tried the diaphragm clutch once in my TR4 and didn't really notice a
difference (must be snappier though and I think is was Borg&Beck). When I went
to replace it a few years later though, two or three of the fingers were
broken off and some were bent in so I went back to the original heavy duty
design (never had problems with the mechanical levers construction vs. spring
diaphragm design). With the increase in horse power I would go with a good
strong clutch whichever you choose.
