another diff bites the dust (long)

Most cars will break their differentials and drivetrain components if subjected to high RPM clutch drops repeatedly.
The reason they don't is that it is actually faster to do a "clutch slip" take-off at mid to low RPMs then to do a clutch drop at high RPMs.
This is why cars like the lude and the R aren't breaking anything. Have you ever had the need to do a take-off with a clutch drop at 6k rpm in your lude??????????????
The reason we do it in the s2k is because our clutch won't grab unless the wheels are shocked into spinning at higher RPM.
Thus, change the clutch for a strong one, and you will eliminate the need for aggressive clutch dropping.

On a seperate note, the FAQ says if you have a flat in the rear, move a front tire to the rear and use the spare on the front. Did anyone who fried their diff have flats?
I think the diff failures might be related to the torsen... In my experience, the torsen starts to give a lot of resistance as it wears out. That resistance might contribute to excessive strain on the casing. That's just my guess tho.
BTW, I have had two rear ends go bad on me. I've had one blowout a few days after I first got the car. I used the front tire on the rear like the manual says and drove very slowly until I got home.

The f-bodies Rev about 2k-3k on grippy asphalt in order to launch, anything more and they will spin and loose time.
The problem isn't only the torque, it's also the following.
At 2-3k RPM, an F-body is forced to go from stop to 14 to 24 mph.
At6-7k RPM and s2k is forced to go from stop to 29-37 mph.
It's puts more stress on the parts when you have to accellerate to a higher speed.... I don't know if i am explaining this well...
Also, on all VTEC cars i have driven including the lude, slipping the clutch propelry yields better 1/4 mile times then dropping it.

Someone also posted that we use Miata Rear Ends? If so, we can definitely see where Honda cut corners. A Miata has 140 hp, the S2000 has 100hp more!
I just don't see a clutch helping that much. Sure it may save it for awhile, but there are also diffs breaking that were not abused. They need to fix the diff even if they change the clutch as well.
service manager called me today. honda NA will do a one time goodwill warrantee repair, very reluctantly. part is about $3k. i will have the opportunity to take pictures once the new part is here and the old one is taken out.

The reason the mags don't do it is because it would take too much time and practice with the particular car.
Just dumping it is easier and more consistent for all cars.
Slipping the clutch in a practiced way yields "controlled wheelspin".
controlled wheelspin = good times.

1. Dropping the clutch and modulating the gas pedal.
2. Easing the clutch out while having the gas all the way down (or at one point) while inducing wheelspin. At the same time feathering the clutch to get wheelspin and grip with the gas on. (This is what I do in my Prelude)
So do alot of Camaro owners just dump it cause its easier? Still, there would be some clutch dumping cause it is easier than slipping the clutch. It took me awhile to get my Prelude right where I can launch well. Still I get beat alot by RWD cars who just dump. But mine is FWD.
I just think that regardless, people will still be breaking differentials even if they had a strong clutch. I've heard alot about pre-loading the drivetrain before dumping. That seems easy. Do you all do this that have had broken diffs?
