Lifted Alignment....

[Simplespirit]

I have an 09 with OME lift, OME UCAs, OEM 18x8 +60 wheels, 3/4 spacers (taking offset to +41), and 275/70R18 tires. The 1" KDSS max relocation kit has also been installed. At this point I have very minor rubbing on the inner most part of the front fender liners (drivers side when turned right and passenger when left).

Front hub to fender: 22
Current alignment spec (most recent one I have anyway)
Camber L -.2 Camber R 0
Caster L +3 Camber R +3
Toe L +.14 Toe R +.14

If I add more caster, is that going to increase the rubbing at the front? Should I have some removed? Or leave it at 3 and massage the liners?

I am going to ask for camber to be +.1 on both sides and ask for toe to be reduced to .06 on both sides.

Much easier (and potentially free) to just mould the liners with a heat gun. No cutting necessary, and although it's a "permanent modification" nobody will ever look at it and be able to tell that it's been messed with.

Reducing caster could potentially move the tire rearward in the wheel well, depending on how it's adjusted with the eccentrics, but it will also make the truck less stable and more prone to wander at highway speeds. Worse, if you move the tire back far enough it rubs in the rear, then you've got much more difficult clearance issues to solve. IMO, it's more important to get the alignment right and then adjust for clearance as necessary.

For a lifted truck in particular, you want as much caster as you can get. I would not reduce it. I also would not want positive camber. Zero or slightly negative is best for handling. Positive caster has no benefit, real or theoretical, for your truck's performance. I would agree that you could reduce the toe-in.

Copy. I meant -.1 on camber so I'll leave caster at 3 and reduce toe.
