I put in a Valeo when I swapped a 6-speed Getrag
for the failed Midlands into my previous MINI (2003 R50).
I found it to be a very good street friendly clutch/flywheel set.
It is said to be very reliable, perhaps even more so than the
Stock DMF. It has none of the problems of lightweight sport
Clutches, and is only a couple # less in weight than the DMF setup.
Maybe not the best choice if you’re going to
go up over 220-240 hp, but neither is the stock DMF.
I do have a 2009 JCW R55 with the stock DMF so I know how
both feel and work.
The DMF has the springs in the flywheel and a solid clutch disc, whereas the Valeo has a solid flywheel
And the springs in the clutch disc.
we started fitting solid conversions years ago back when the first wave of failed dmf's started to appear noticed a pattern, big diesels eat them, mapped diesels eat them, and above all driver style kills them fast,, by driver style i mean picture this you buy a diesel because it will do 70mpg but only may to do 70mpg is drive as low revs as poss under 2k everywhere trouble this causes max rotational torque load on the flywheel all the time, this keeps the springs in side under max load then every gear change they release and go the other way..
this all said we fitted a lot of smf to these cars over the years and rarely seen them back again and owners just slogged them in to the ground while getting good mpg,,
now the other cars that got driven high revs everywhere on smf hmm they had different problems with vibrations and gearbox breakages .in fact remember a builder with a transit tipper went through 4 gearboxes until went back to dmf then it was just dmf every 50k , as gearboxes are made weaker with dmf designed use,
so to sum it up its all about how its driven and what use is expected of it,,
one mod i would never do again is a solid flywheel with paddle clutch on a road car, the best solid flywheel kits and they also do a 400bhp plus twin plate conversion is produced link below CG Motorsport Twin Disk Clutch Kit - 184mm Sintered Drive | CG Motorsport
