For those running lots of caster…

Who’s had issues when running 5* caster with the struts striking the strut tower? I had that happen the other day and it rolled the top, lipped portion of sheet metal up. I’m not super low or on stupidly soft springs like sportlines. 800lbs 5.5x12” springs for just under 27” floor to fender ride height, but think I’ll be going up to 900lbs-ers. My question is just how much material can be removed without compromising anything and does it need to be welded or otherwise reinforced after removing said material? I ask because there is a stamped lip that will add significant rigidity to the circumference of the factory hole but with that cut out I’m losing that engineering feature. Thanks.

You shouldn't have to be setting the strut mount that far back to achieve 5 degrees unless something else is messed up.

As for a fix, I doubt flattening a small.portion of that lip will do much. Worse case, bend it back and hammer into the origonal shape.

Flattening will solve nothing. Metal will have to be removed. Simply flattening the lip will still have it in the way and getting smacked by the strut next time I full-stroke the front suspension. As for anything “wrong” with the car, it is straight and nothing is wrong with it. I was a little off on my caster, it’s 5.5*.

The damage and where the strut resides to get that 5.5*.

Alignment specs.

Probably needs new bump stops if that's hitting. The suspension is simply travelling too far.

Re: For those running lots of caster…

+5.0 castor shouldn't even come close to having struts hit the chassis.
you can run +6.0 or more in a lot of cases.
I'm gonna guess here since I can't physically see the car

1. The alignment place put the tool on the wheels wrong.
2. Something is bent in your suspension
3. Steering stops might be bent or broken.

Pick is my completely out of alignment 92.
no strut contact.


Alignment WAY off
