    No I dropped the car on the ground to tighten the rear shackles. I talked to Hotchkis today....they told me to check the rear for level. If it isnt they suggested reloosening the rear then tightening back up. He told me if the pass side rear is high, it will lower drivers front.

    Quickie alignment check- put your level on the rear wheel, note the bubble position, then check the same on the front. Bubble should show the top of the tire leaning in slightly compared to the rear, if you are "in the zone" of correct.

    I ran 245/50/16 on 16x8 with 4.5" BS, and 275/40/17 on 17x9 with 5.0" BS. Both are same basic height and put the outer edge in the same spot as yours, and I didn't have any rub... barely. I would scrape the test blob of toothpaste off, but no noise of contact. Didn't take the paint off, either. However, I had the Z28 bump stops (bump stop with 5/8" aluminum spacer underneath). This limited suspension travel to prevent the rub, but also meant that with my 420# front springs (Moog 5610), I was sometimes bouncing off the bump stops on big dips. It was a slight tradeoff... one that I got rid of when I switched to 17x8 with 5.0"BS, along with 707# springs.:)

    What's the wheel center to fender lip distance? That's the "universal" measuring standard for us, since it takes out the tire height as a factor.

    Todd80z28.......the measurement from center of the hub to the fender is:

    Pass side: 13 1/8"
    Drivers side: 12 7/8"

    That is pretty dang low, especially for the offset you have. Will you hate the look if you raise it slightly with some spring isolators/spacers?

    Same EXACT setup I have. Hotchkis TVS
    Except I also had SC&C UCA's and HPS1000's (Bilsteins) installed with the system.

    Mine actually sat too high so I cut one full coil out.......and then had your issues.
    I ended up having to raise them back up with coil spring isolators.

    I ordered a 3/8" spacer from Global West tonight which they told me would raise the drivers side 5/8" and said it will raise the pass side by 1/8" (i dont know how, but thats what they said).

    That stance shouldn't be rubbing a fender, but I can't tell for sure.

    My front tires were actually sucked into the fender too deep when they rubbed.
    I have a picture here looking eye level to the fender lip.

    This was eye level after I reinstalled a 3/4" (iirc) coil spring isolator to perfect my stance.

    I copied Todd's 4th Gen wheel install data, but do not have the Z28 bump stops.

    Drivers front : 14-11/16
    Pass front : 14-3/8

    Drivers rear : 14-3/16
    Pass rear : 13-11/16
