'01 M3 axle hop
Hi All. What can be done to reduce or prevent axle (wheel) hopping during a
holeshot start? It's pretty bad through first gear on my 2001 M3 Couple. TIA |

The DSC is switched off. The holeshot I am talking about is a drag racing
sort of start. Rev the motor a bit and dump the clutch. When a lot of throttle is used and tires start to spin, at a certain point the rear wheels will begin to bounce. Sometimes it will actually shake the trans into neutral (from first gear). In the old days, "traction bars" were used to control this sort of thing.

I think you need anti-tramp bars - should be available from your local
"hop-up kit" store (sic) And letting the tires (sic) down a bit might help ... Why's it called a holeshot start??? "Planar1" > wrote in message ... > The DSC is switched off.

TIA Is your goal to prevent hopping completely so you can get off the line faster, or are you only worried about the shear torque produced damaging your differential? Have you already got good tires on? Is your positraction working? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Are you using slicks? --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

The posi works perfectly. The tires are Goodyear F1s (I think that's what
they are called). I'm not running slicks. Not looking for a true drag racing set-up. All I want to do is have "fun" a little more safely so not to damage the suspension or anything else.

I don't want the DSC on. I want to play! Isn't that one reason we drive M3s?

No that's the reason one buys US cars with huge V8's and pathetic dynamics.
