Anybody running 17" Cobra Bullit rims on a Duster

To get big stock-type or MP bars down to a lowered-looking ride height (lower than stock by a good bit), there may be very little or no preload on the adjusters. I've got 1.14" bars and only enough preload on the adjuster to keep things from rattling. I suspect I could remove them and be OK with the ride height, but I drive this car on real streets, so I'm a little higher than "race".

For alignment purposes, you want to be low enough that you're on the compression side of the movement curve. That may help a tad with the alignment setup, but you'll be close to or on the bump stops. I personally don't think that's a big deal, as the bigger bars don't need as much suspension movement, and a stock rubber bump stop acts like a variable spring as it compresses. FWIW, I have NO compression bump stops on my car, and I don't think I've made any LCA/chassis contact. I'm not doing any Duke Boys maneuvers, either.

I agree, dump those fat stock rubber bumpstops. I'm about 5.5" from the ground at the back of the K-member. I've run 1" (.99) T-bars since 1993 and about 60K miles. I'll get you a top of fender lip distance on Wednesday night if I can remember.

Driven all over hell with it that way. The car was even lower when I ran Pirreli P-Zero 225/50/15 tires instead of the 245/50/15's I run now.

When I ran the 225/50/15's the K-member would NOT clear a parking lot concrete bumpstop. I drove across country with those tires. They suck in the snow BTW. But with 180? treadwear, they didn't last a long time.

If you really feel you have to have bumpstops, check Summit for poly bumpstops and the thinnest they sell is like a 3/8" round one that will bolt rignt into the Mopar LCA.

OK, what is everyone's ride height? how far is the lower control arm bump stop from the frame, and how far is the middle of the K-frame from the ground? what is the average/normal ride height?

Reilly is telling me that:
"1.0 inch torsion bars are WAY too stiff for a small block car and that with a ride height that high, geometry sucks. It will still wander all over the place, and since those bars are totally unwound at ride height, the ride quality will be miserable."

So, now I have the ride height down, and the LCA bump stops are just touching the frame...The torsion bar adjuster bolts are almost all the way out...Is it possible I installed the torsion bars wrong? can I clock them a different way? does it matter?

Here's my LCA distance with no bumpstop installed.
