The car magazines put the 0-60 times at like 5.6 or something, fast has to be well under 5 seconds in my book without driving like you want to break it. I am sure you have surpassed the car mag's times, but my butt dyno says this isn't an Evo, STi or 911. The fact that the clutch is so weak, says where Honda intended and spent their budget on. It's much more a car to go fast when already moving.
ok, so name another roadster you can buy for $30,000 that can do 0-60 in under 5 seconds? oh that's right, you can't.
hell, hardly any of them can even do it in 5.2-5.4 like the S2000.
so if you want to be comparative, why compare cars that aren't even in the same class as the S2000?
and complain about the clutch all you want. well over 500 dumps on my original clutch already, and I'm at 60,000 miles. if you know what you're doing, the car will be fine, and so will the clutch.

actually you have this exactly the opposite.
you're confusing load with the sudden change in the drivetrain/diff from zero movement to higher rpm movement.
if you dump the clutch, your drivetrain and diff only takes an initial "quick shock" or jolt as it jumps to life. yes this puts some wear and tear on the car, however, the LOAD is lighter on the parts if you properly spin the tires on the launch. this is because the tires are spinning, so there is some freedom of movement to the drivetrain and diff, as the rpms fluxuate under the spinning of the tires.
if you slip the clutch or bog the launch, what happens is the rpms go from being up to way down very quickly, and rather than your tires spinning, they are solidly planted on the ground. this puts the entire load of the weight of the car squarely on your drivetrain and diff. this is more than likely how many suffer the bearing cap flex under heavy load that causes diff failures. (at least from what I've seen, read, and researched on the site)
so it IS better to do a full tire spinning launch. the tires spin allowing the LOAD to be gradually worked into the drivetrain and diff. bogging/slipping does the opposite and puts the greatest strain and load on the drivetrain/diff.

I've been practicing since I saw it and it's definitely a big help. I must admit, dropping the clutch at 6K is still harrowing. I'm still getting used to the fact that I have 3K more to play with

you will get off the line faster AND have a faster time if you launch with some wheelspin.
if you just bog or just "go" you will run actually a MUCH slower time. if you don't believe me, feel free to go test it at a track and you will notice your 60' (60 foot) time and your ET will be much slower without a proper launch.
if you get the tires to spin, you DO have some traction, and what's happening is you have the car in it's power band, so it's providing the most power, moving the car forward, and getting the car out of the hole quicker.

lack of a proper launch can put heavy strain on the diff. IMO, from what i've read and seen over the years, this is likely one of the more common reasons diff failure occurs. driver error or improper driver skill.
and yes, all 0-60 times posted by car mags are with a launch, as all production vehicles need to be launched to get the best times.
