So I'm already hemoraging money all over the suspension bits of my car. Why stop the bleeding so soon when there are so many parts to buy... (IMG:style_emoticons/default/happy11.gif)
When the car goes back together I'm lowering it as far as practical for an AX/street ride (my driveway may be the ultimate constraint). I've already experienced the near complete elimination of bump steer by installing washers under the steering rack so I never want to put up with bump steer again. So I'm looking at my options and see two. The first is to install a ERP bump steer kit (hit page down a couple of times to find it) so I can dial out the bump steer no matter where the ride height is set. The second option is to go to the Tangerine racing raised strut spindleswhich appear, looking at the digipic, to have the control arm bent to a corrected position to eliminate bump steer while resetting the ride height via the relocated spindle. I suppose the raised spindle also has the advantage of not using any of your suspension travel to achieve the lower chassis height. Whata ya think? The price is a wash. Anybody done both or one or the other to provide and comparison/comments? Oh this all assumes that the dreaded bump steer will show up with a vengance as I crank the car lower... Thanks, Kevin |

QUOTE(TMorr @ May 29 2003, 12:09 PM) <snip> Raising the spindles also has a positive effect on restoring some height to the front roll center which is adversely effected by lowering the car, also exacerbated by larger Ø wheels & or tires, which fortunately allow additional space inside the rim to raise the spindle to recover.... Hayden PTBT Is lowering the front roll center undesireable because the rear roll center is going to be higher than the front no matter how low the car goes? What does this all mean in terms of handling taking two different and extreme roll center scenarios and all other things being equal: 1. Front roll center is crazy-low from lowering the car and the rear is where ever it is from that lowering. 2. Front roll and rear roll centers are at factory (let's say european) spec height. I've just started looking into this stuff (I've got Puhn's book) so any prospective, especially pratical prospective is appreciated. Thanks, Kevin |
