<VV> Clutch Pressure Plate

[Larry Forman]

Hi Andy,
Some people machine the 140 pressure plate to reduce weight.  I have heard that the 140 pressure plate is made out of different material in addition to being heavier and might make for a better long term solution, but more work and expense.  I have had some 110 pressure plates built up with 140 heavier springs to retain the greater frictional grab.  You might try that, since it would be easy to take a 110 PP and a 140 PP and disassemble them and rebuild the 110 with the 140 springs.
