Hey guys, I have a theoretical question and hoping to get opinions and thoughts on it. I've always had a pull to the right under hard acceleration that I had thought was due to the lunchbox locker in the rear. Alignment is good. All bushings and joints in the suspension are good. Cruises straight and drives great while not accelerating hard. No DW or bumpsteer. Like you have to really punch it to make it pull. When you give it gas hard and it pulls, you can kind of feel the front left lift up more than the right side.
I was watching Roadkill and a light bulb came on when they were talking about weight distribution of drag cars. What if my Shittybilt XRC spare tire bumper (35" KM3 mounted) puts more weight on the passenger side of the bumper than the driver side? Out of curiosity I measured and sure enough the rear passenger side sits a little more than 0.5" lower than the rear drivers side. Makes sense to me since the hinge is all of the way passenger and the striker is about a third of the way in from the driver's side...which would put the tire weight slightly towards the passenger side of center assuming the hinge and striker take half the weight each. Seems like the hinge would take more than half the weight though. Also the gas can sits on the passenger side of the tire carrier. My adjustable shackles are the exact same length and the turns screwed setting the length were the same side to side.
A) So has anyone else noticed something like this with a spare tire bumper, specifically the XRC?
B) Would lengthening the passenger side shackle back to level help or hurt anything? At least it would be level but the weight would still be offset...
