Message: [QUOTE="euroford, post: 1523792, member: 17667"] on clutches... i've stuck with south bend, i've been happy with both the units and the customer service. You can stick with a single disc if you want, but if you go with those 200cc injectors you'll have to be cognoscente of the fact that it won't last all that long. maybe you drive easier than me (i do some drag racing and enjoy driving it hard in the mountains), so that will help but you'll certainly be on the edge of a single discs capabilities. After going with some swamps hybrids (great stuff!) my single disc put up with that for about 15k miles (and about 20 passes down bandimere). then i went with south bends "street" dual disc. it lasted about 20k miles until i lost the front main seal on my ZF6 and got oiled down. This clutch was doing well, but after about 10k miles and a visit to the drag strip it was feeling pretty funky and i had a lot of drivetrain slop. when i pulled the clutch out i found that the damping system added to keep the "street" dual disc quite was totally destroyed. both the little rubber dampers on the center plate and the rubber dampers in the clutch plates. so for my 3rd clutch, south bend set me up with what they call the "super street" dual disc. its the same as the regular street dd except the damping system is eliminated, it uses a solid center plate without the rubber bumpers and the clutch plates have all steel springs. yes, you can hear it just a bit when you push the clutch pedal in, no it doesn't bother me at all. this is a no cost option, but you have to call them to get a custom unit assembled. highly recommended. having rubber dampers in your clutch is a dumb idea, they heat up and get destroyed. its like having a failure point built into an otherwise solid setup. a dual disc does shift just a tiny bit slower. adding new hydraulics, the heim joint mod on the clutch pedal and Redline MT-90 oil in the trans all helped keep things shifting smoothly. the tiny bit of slowness in the shifting only bothers me when drag racing, for normal driving and towing it shifts perfect and smoothly. you'll have a pretty solid setup, mine is very similar. i just dropped in a KC38r 63/73/.84 (one of the first for e99) and initial impressions are GOOD, so count me as a fan of KC Turbos.
