I track a 97 M3 that is moderately modified and sees both street at track time. In the M3 world the best results with suspension have tended to come when using aftermarket coilover suspensions. The coilovers use matched springs and dampeners (non, single, and dual adjustable) as well as correct dampener piston travel. When using mix-and-match struts and coilsprings, usually the spring rate will be too high for the dampeners and the travel in the dampeners will exceed the coil.

I have been researching doing a 944/951 as a dedicated track car b/c of the light weight, 50/50 balance, and cost-effectiveness(?).

I'm thinking of a super-light CSL version of an E30 M3 with a turbocharged E36 M3 engine. Now THAT would be quite the track car, eh?

If you are in So Cal I would rethink the forced induction for the track. Of the 2 M3 turbo set-ups, Active Autowerke's if far more complete and dialed in than the Mech-Tech. Both however may develop significant heat-soak problems. Both are starting to incorporate the RMS water-injection units now.

For a really bullet-proof monster, I would use the E30 tub and drop the inline-six in, have someone like Chuck Stickley (cssmotorsports.com) build you a 370hp N/A E36M3 motor for about 12k and drop it in. On pump gas he could do a 330hp motor for about 6-7k.
