hey guys...i know that dropping your clutch is probably the worst thing for a car (along w/ donuts) but i need to get of the line quicker. I have only done it a few times around 3000-3500 i let it out and i get wheel spin and then im off. last night i was racing a w8 and i was watchin his fingers cuz he was counting down and before i knew it i was almost redlining and my tires were spinning like mad all the way through 1st. and i know that my 328is doesnt have that much power. anyways, i have heard people talking about slipping the clutch instead of dropping it. if some one could hook me up w/ the right way to do it that would be sweet so i dont have to go and get a new clutch anytime soon. peace guys

Slip it.
Dropping it will torque just about every undercarrage & suspinsion part very hard and very suddenly. Sudden, sharp and very strong forces are much more damaging than a very strong force spread out over a little more time.
It's the difference between getting hit by a bullet traveling a thousand feet per second and one traveling 10 feet per second. One hurts, one kills you.

You'd much rather have a worn out clutch than torn up gears.
Clutch replacement is much easier compaired to fixing a gear.
If you tear up a gear, you gotta find out which one you tore up... your diff gears, or some in your tranny... Or both. Then, you have to disassemble the entire unit, replace the F'ed up gear, and examine the rest of it to see if any other gears have been damaged by floating metal shavings or chunks. Lots of labor.

Or, if your just trying to slide around, start normally or kinda hard, get some momentum, say 20-40 mph (once your in the torque band), and jerk the wheel to one side and then back to create a large weight shift, and stomp the gas. Wala, not so stressful on the driveline and the rest of the car.


Doughnuts arn't as bad, stright out burnouts while you are holding the breaks not only can tear up the gears (if you dropped it), but it will WEAR OUT your rear breakpads and rotors, and if the heat gets really high (which it will, really fast) you can boil the brake fluid and then you got air in the lines and your brakes will be all messed up until you bleed them.

First off, if you want to race then spinning the tires is not what you want to do. Sure it looks cool, but if your spinning your tires then a larg percentage of your HP is not making contact with the pavement (ie: you are accelarting slower then you would if you weren't spinning the tires)

Dropping the clutch is bad idea. The key to your launch is to get your engine into your powerband before you let out the clutch... that way you are making maximum horsepower as quickly as possible from the launch.

I've have yet to drag my 328, I doubt I ever will, but you'll want to rev err up somewhere between 3K-3.5K for your launch. When launching, your gonna slowly let out the clutch (like you would in normal driving) while at the same time you basically put the gas peddle all the way to floor. Its gonna take practice to get it perfect, but your goal is to get as power ready for your launch as you can, then using a clutch/gas combination that gets all your power to the pavement without spinning the tires.

If your not good at it, you might want to try having a friend timing your launches:
1. Without ASC-T on (with your wheelspin)
2. With the ASC-T on (ie: no wheelspin launch)

I bet that the ASC-T on launch will be quicker then non-ASC-T launch while your learning.... once you get the hang of keeping the wheelspin down, then the non-ASC-T launches will be quicker then with it.

Good luck

For a 328 it will be different then for me. First you need to find your peak tq. Then you want to launch just above that. For me it's about 4500 rpms, that's a little high so I ussually go at about 4k.

Bring the revs up and hold them steady at whatever rpm you desire. Then you let the clutch out so it starts to grab at the friction point. Quickly let the clutch out all the way but DON'T just sidestep off of it and at the same time quickly squeeze the gas down. Don't just stomp it all the way down because it's hard for the computer to adjust quickly enough for all the extra air and you'll bog the launch.

If your tires break loose keep the gas to the floor but feather the clutch to regain traction. It's tricky and takes skill but eventually you'll get the hang of it.

By the way, this method is VERY VERY hard on your clutch.

so all in all, dropping it is way worse, which i know, and slipping isnt that much better for it. i just hurts the clutch. thanx for all the input, i have to go out and practice now. i was jw because i had the huge wheel spin incident . thanx again
