A few years back, Bruce found that we can mate the e39 540i JB/UUC lightweight flywheel to an m52 clutch kit, and the e34 530i zf310 trans. A few of us did that, using the Clutchmasters fx100 m52 clutch kit. However, mine started slipping after 12k miles, so now I'm back on the hunt. Clutchmasters doesn't have anything above that stage one kit. SPEC makes an m52 kit, and they rate their stage 1 at 345 lb ft, which should be plenty. It's an organic disc so it should operate like a stock clutch. Some other people have done other combinations... but I've yet to see any results after long term and/or abusive driving.
However, I found that a company in the UK, TTV Racing, has began producing a steel single mass m60b40 and m62b44 flywheel designed to be used with an e36 M3 clutch kit (it has the correct locating dowel and PP bolt hole locations). This is great news, since the e36 M3 uses the ZF310. The flywheel is 16lbs and the price they quoted me was $530 to my door (very cheap compared to UUC/JB, and the same weight). They claim they've sold 40 of these special flywheels already.
As far as I know, all e36 M3's clutches are the same; Euro vs US, 3.0 vs 3.2, doesn't matter. The Euro e36 M3 has a 321hp engine, which makes around 280whp, more then any stock m60 has made that I've seen. I'd think the stock e36 M3 clutch would hold the m60's torque with no issues. If not, there is a much bigger aftermarket then there is for m52 clutches, so there's plenty of options.
I haven't decided what I'm going to do yet, but this seems like a very good solution, and I just wanted to share.
