Ok, so now that we have stepped up the game and have found more lateral cornering G's I am in lifting the inside rear tire again.
No rear sway (of course) High rebound rear shocks 200 lb rear coil over. high rebound koni race shock and 21mm torsion bars in front with 22 Weltmiester bar. set as much as I can before the car pushes. So looking for advise on LSD what's available and what's the difference of each in an autocross application. |

Especially when the frequency of ordering and installing the wrong parts for a certain application is signficantly reduced (IMG:style_emoticons/default/beerchug.gif) I was watching a honda do the sweeper last weekend, and his best was when the inside rear tire was lifted (and locked-must be trail braking) for about 140 of the 180 degress (IMG:style_emoticons/default/huh.gif) |

I was watching a honda do the sweeper last weekend, and his best was when the inside rear tire was lifted (and locked-must be trail braking) for about 140 of the 180 degress (IMG:style_emoticons/default/huh.gif) That's actually ideal for a car like a small Honda or VW. The suspension dynamics for a FWD car are a lot different than a RWD. For the Honda, the only purpose the rear wheels serve is to keep the gas tank from dragging on the ground... Okay, an exageration, but the rear wheels really don't _do_ that much in a front driver. The front wheels are doing everything (steering, acceleration, and braking). They've exchanged the roll stiffness in the rear, for roll stiffness in the front, to keep the inside front on the ground as much as they can. Like when a 914 or 911 lifts an inside front, but with even less of an impact on the handling of the car. As for the wheel stopping? Try spinning the wheel of a car while it's off the ground. It doesn't just spin like a bike wheel. It'll stop pretty quickly once there isn't a load on it. That rear wheel will stop rotation pretty quickly once it comes up. That was a well driven Honda. A1 and A2 VW's are the spookiest, with the torsion beam rear axle, you can sometimes clear a beer can under those wheels... BTDT, and went too far... -Josh2 |
