Hotchkis tvs system questions

Excellent information everyone. I am questioning the leaf springs from the kit now, I certainly do not want to lower the rear any at all. I have 15" x 235 on the rear and they rub easily if any weight was on the back like if I had a passenger in the back seat.

That's a backspacing problem, not a tire size problem. 235's in the back are tiny for a Dart Sport/Duster/Demon body.

I fit 275/40/17's on my Duster bone stock, no modifications at all. I now have 295/35/18's on it in the back, although that's with a 1/2" spring offset and some trimming of the inner quarter lip.

Sounds like you have the wrong rims on that bad boy.
