I am not sure if you need to be registered to read the threads, but if you are the info contained within is definitely worth the few minutes it takes to sign up. There is info on engine oils, tranny fluids, and gear lubes that pertains to all cars, not just S2000's.
You summer-only and race-only guys should really look into a product called LE-607 (read articles at link above to learn why), all the testing shows its a better choice than the Redline Shockproof stuff for both the street and track. Redline techs recommend against using the Shockproof in street cars due to odd viscosity behavior at low(er) temps.
