hhmm stock launch, best launch is smashing limiter and slipping the clutch, isnt good for the clutch though.
dial up say 6000 and release the clutch and your away. best shift point is around 7k. -------------------- ST205 Group A Rallye GT-Four, #61 of 77............600hp GT3582r

this makes me cringe how long the gearbox/diff will last haha, my friend had a wrx and launched it all the time and got 400k out of the engine and the gearbox was still going, the way he did it was let the clutch slip, rather than dropping it, so all the wear went on the clutch rather than the gearbox, I don't know how true this is.

he didnt mention what is the best for gearbox longevity
 when im drag racing i "preload" the gearbox, basically as in staging i pull the handbrake on, then release the clutch ever so slightly so it "loads" up the gearbox ever so slightly, so when you do drop it there is no heavy CLUNK as everything meshes. -------------------- ST205 Group A Rallye GT-Four, #61 of 77............600hp GT3582r

I've never dropped the clutch on my st205, scared I might break it... I don't really get to thoroughly enjoy the car like I did with the st202
I hope to throw it down a track some time and check out the end of my 3rd gear aswell as a limiter launch (maybe just once) and hopefully get a 14.0 or something?

Launch control is set at 4800rpm on mine, seems to do the job. 6500rpm is the best shift point as power tends to start dropping off after that but each and every car is different...just get the feel for the car and shift accordingly, there us no hard and fast rule as to when to change gear.
