Given my personal high-perf BB C3 street machine experiences:

First, quicker gear changes, particularly downshifts, as you can match RPM's between engine and transmission easier. Plus, the consequences of a mis-match aren't quite as bad.

Second, less driveline breakage. Before I went to the 15lb. flywheel, I was constatly breaking something, from transmissions to stub axles. I beefed up everything from 1/2" wheels studs and HD stubs to a 12-bolt IRS package. Once I broke my T-10, I got rid of the millstone.

Third, better traction. Being this car isn't on slicks, the reduction of rotational mass actually improved my ability to put the power down. Sure, it may fly in the face of convention for some (stop thinking mouse motor), but when you have enough torque, high shock loads and street tires don't add up to a very good launch.

The downside is that funny car style burnouts aren't quite as dramatic as they used to be, and I'm sure if I were on slicks at the strip that I'd pay a penalty coming out of the hole. But, this C3 isn't for that.

I like the plus side so much that I'm considering still further reducing rotational mass by going to a small diameter Tilton SFI multi-disk clutch setup. Anyway, that's my story and I'm sticking with it. So, let the opposing views begin...
