Post Clutches, Gear Sets, & 4,000 rpm Launches

First off I did a search about the above and read what was available.

With my mostly stock WRX I like dropping the clutch at 4,000 RPM when doing a dragstrip launch.

Now a question for all of the Scuby transmition gurus and racers here...

- Am I doing damage to the clutch/flywheel and/or transmission? Or just quickening the wear of the clutch/flywheel. I'm not hearing anything "bad". Just spinning the tires a tiny bit then hold on!

- Can anyone recommend a clutch that can take this "abuse" and last? ACT seams popular.

- Do I need to upgrade the gear set?

FYI- My WRX wagon with everything in it and a 1/2 tank of fuel can do 14.5sec 95mph 1/4 mile times all day long according to the G-tech.

AWD is made for 1/4 mile bracket racing.

Dropping the clutch is BAD!
there is a 1,700lb or so pressure plate on the WRX so it will hold that shock and transmit it all the way to your gears, which DON'T like that!
Don't get an ACT that will only make matters worse...(more shock)
I have had my fastest launches with slightly slipping the clutch at the right rpm and give gas as you finish letting the clutch out (It took time to get this down)
I still spin all four tires and get shoved into my seat... (and it doesn't bog)
First rev the motor to get exhaust gases up and spooling that turbo... then time the rest and hold on!

Question

Does anybody know what is different between the RS and WRX transmissions other than the gear ratios?

Is the WRX gear set stronger than the RS? I thought I read that the STI gear set is stronger than the normal WRX.

Deduct about 2 mph from the GTech mph and youll have a number closer to what youll see at a track. The ET given by the Gtech is usually fairly close (within 0.2 seconds) assuming its installed perfectly. Sometimes bumps in the road also provide erroneous readings.
