John---I have found the "flat fingered" B&B pressure plate to be
lacking in clamping force. The "cranked fingered" and Blue Dot is up to
the task
The small difference in frictional area should not be a concern.
Apparantly there are many TRs running with a mixed set of Laycock and
B&B, with no problem because of the mix.
The circular groove seen in your old pressure plate (fingers) is common,
and caused by two things:... The throwout bearing making initial contact
with the spinning clutch, and the wiping of the fingers as the clutch
dis/engages. Installing the Gunst with the preload strap and spring
will minimize this wear.
You should be fine with what you are planning to install.

Clutchs Laycock & Borg & Beck
Hi All-
(clipped).
...I was out the the garage b.) The clutch plate is a Borg and Beck with
the straight fingers. There is a pronounced circular wear groove on the
fingers. c.) I may have had some oil leakage on the clutch and plate.
....It seems to me that the new B&B clutch has nearly 5% less frictional
area than the Laycock. Am I splitting hairs here?
My new B&B pressure plate has cranked fingers and a blue spot. What is
the difference between a blue spot and a yellow spot clutch?
Thanks
John Cyg.
