Jason,
Have you looked into using longer ball studs for mounting the front dampener? I've also switched to long ball studs and now the dampener has considerably more travel as the suspension moves which has improved my cars' handling.

Really? So just replacing with longer ballstuds so the tube sits higher up on the lower arm somehow changes the 'effective movement' of the damper tube producing better handling? Someone please explain this....

The longer the ballstuds the more damper movement with the same amount of movement of lower arm. Effect is the same as thinner lube in damper tube.

Quick couple of questions about the effects of various options on the new front end (basically more / less front end and where in the corner!)

More droop / less droop?

More Castor / Less

More / less Camber

Thinner / thicker oil in damper

Raising the standoffs?


Thanks!

More droop / less droop? more: better on bumps but will reduce on power steering. Less:more on power steering but hard to plant front on bumpy tracks.

More Castor / Less More:Will give you more steering. Less: Will reduce steering.

More / less Camber Same as Castor

Thinner / thicker oil in damper Dampening will smooth out the front spring rate. If you increase dampening, you slow the reaction of the spring. This is a nice tuning option as it can help you mellow the car down if it is irratic.

Raising the standoffs? Raising the standoffs will lower your roll center and lowering them raises your roll center. When you lower it, you increase chassis roll and when you raise it, you decrease chassis roll. We have been lowering the roll center because it makes the car more smooth by reducing side bite. When the car rolls, it absorbs the weight instead of transfering the weight to the tires and making them dig harder.

Higher ball studs will make for longer lever arms on the damper...thus more travel on the damper.

the damping is proportional to the square of ball stud length. if you double the length, the travel doubles (increasing the viscous force in the tube, and the tube is acting on longer lever arm, so the damping increases by 4x's

speed-e is a clever fellow..

It would be interesting to see what he could do with the full Copperhead, though his R5/BMI is plenty quick as it is...

Will the lowered pod plates for the DB12 (DB1054 and DB1055) fit the Copperhead?
