ooh,an extra gear!!

At low rpm(under 1000) there is more vibration, at higher rpm no problems at all.
My car revs quicker and accelerates faster especially in lower gears with the smf,maybe not much of a weight saving,but the weight is nearer to the middle of the crank so is easier for the engine to turn. . . . .a bit like an ice skater when they pull their arms in and spin faster?I am only guessing about that,but the engine does spin up faster!
I have heard of the theory about crankshafts breaking,but I have never actually seen one.Not saying it doesn't happen,but there are a lot of smf conversions(on different makes of car/van) about that have been trouble free for many many miles.
Clutch cylinders don't need changing,but the clutch bite may be slightly higher up because the smf/gta clutch combination doesn't stick out as far as the dmf/clutch does.
I don't think the flywheel will need lightening or balancing,but if it is not a new flywheel,it may be worth getting it 'refaced' just so the new clutch works on a new,flat surface.
