to lower the front coil overs are the trick.They do not screw up the front end settings or handling Did you use their upper control arms also?
Hotchkiss is the only ones that I know of that have the bracket to reloate the upper A arm rear attachment point . This sets the plane of the A arm shaft to what would be parrell to the t bar. This helps eliminate the front end changes during travel.

I thought the front end changes during suspension travel (bump steer) had more to do with the steering links following the same arc as the upper and lower suspension arms so that the steering linkage isnt pulled when the suspension travels up and down...causing the car to missalign throughout the suspension travel causing the steering on the car to wonder all around while the suspension travels.
I dont see how coil overs would do any better than a torsion bar for adjusting the height. The suspension components dont care if its a torsion bar or a coil over that holds the suspension at a certain level. nor if its a coil over or a torsion bar that makes the suspension travel a certain range...
the only way of lowering a front suspension without messing the concieved geometry and range of motion that it was designed to work at is by installing a dropped spindle.
what im asking is if, with the Hotchkis relocated upper A arm, the suspension was designed to work at factory height or at a 1" lower height than factory to work with the 1" lowered leafsprings that the Hotchkis TVS system comes with.
If the hotchkis system is designed to work at stock height, then in order to match the 1" lower height at the rear I will need to get some 1" dropped spindles.
I guess Ill just have to bolt on the front suspension , put the car in the air and see how bump steer reacts throughout the suspension travel....
or call Hotckis and ask, if they ever pick up the phone....
their website's FAQ doesnt say squat about this!

The question is: does the hotckis stuff alos make possible to lower the front suspension to match the rear suspension drop by just loosening the torsion bar or will it mess up the suspensions geometry?
Do you have to buy a 1" drop spindle elsewhere??? or is it no needed??
Yes, their system allows you to lower the front end via turning down the t-bars without creating a mess with the geometry. While droing the nose down this way will alter the geometry some, it will not "mess it up" so to speak, any worse than it was to begin with.
The biggest benefit to the Hotchkis layout is that it reduces dynamic caster changes during suspension cycling. THis creates a more linear change during bump which helps reduce some of the impact of bumpsteer that is inherent with the mopar design.
If they provide you the spacers to correct bumpsteer, definetly use them. You may not totally eliminate it with their kit, but it will help.
BTW, no one makes a 1" drop spindle that is widely available from retail vendors. I have seen 1" drops made from standard spindles and the 2" cast steel units that are sold through several reatilers, but that's it.

Domingo – Thanks for your purchase. Sorry you did not get an answer on the phone. Did you leave us a message? We were giving our employees a much-needed Holiday get-together break on Friday. You can definitely lower the front suspension by adjusting the torsion bars without messing up the geometry when you’ve installed and adjusted everything to specification. In fact it's best to lower ride height by adjusting the torsion bars that's what we base our geometry design on. We suggest lowering the ride height. Stock ride height will work too, but lowering the car will get better weight transfer and center of gravity with optimal geometry. This is due to the Hotchkis adjustability and design which has incredible bump steer with less that 1/32 of and inch during suspension travel. If you install an aftermarket spindle you could throw the geometry off. http://www.youtube.com/watch?v=VzxPWrdPlt0http://www.youtube.com/watch?v=FZX7jINa_hoYou can see how low our E-Max Challenger is with stock spindles.  These other two cars are using stock spindles and use torsion bar adjustments to lower the ride height and they perform and ride great! http://www.youtube.com/watch?v=MQ_ja6nfVYwhttp://www.youtube.com/watch?v=VX-B0AtfobA

When are you guys coming out with your own steering upgrades (hotchkis steering box and coupler)????
Domingo – That’s a good question. We have been working diligently on suspension parts for many different applications that other manufacturers don’t produce. We’ve had great luck with the steering components we have on the E-Max Challenger (circle track style steering quickener in the column along with a Flaming River Box) and didn’t have to re-invent the wheel.  If anything changes we'll definitely let everyone know.
