Rear camber - can I adjust it to zero?
The title pretty much says it all. I want the tire patch to be even down the strip, and I'm wondering if my camber is adjustable enough to get to zero or +.

I doubt anyone ever tries, but my guess is that it can to zero or very close to it. The limitation on getting max camber in back is actually the toe adjustment: you get a to a point where more camber forces toe out because the toe adjusters run out of range. That might be an issue going trying to get to zero, but in that case it would force toe in, and a little toe in isn't a bad thing for drag racing. So I think you can get there.

Note that this is a terrible idea for anything but drag racing, and will actually give you less rear lateral grip and make the car more prone to spinning out!

Sounds like you've got a pretty serious car with some serious goals. Get some SPL Arms and dial it in.

+1 on adjustable arms if needed to get to zero camber.
Also, for straight line traction, bigger diameter is the answer. Larger tire patch longitudinally versus larger patch laterally.

Agreed. My Mickey Thompson ET street R 305 45, 17 Is the tallest 17" tire I can get on it at 28+ inches. Their 315 will not fit.

I sent your SPL arms to my mechanic who came back and said he has these adjustable upper arms from AN Performance in stock. Have you seen them? They have been popular on Mopar. https://aadperformance.com/products/6th-gen-drag-pack

So I've read through this and has the original question been answered? Can it be aligned to zero with stock suspension?

You should be able to get to at least 1.0 with the factory arm. My passenger side is at -1.0 and the adjustment cam is in the centered, neutral position. That tire wore perfectly flat over it's 26K mile life. The drivers side is at -2.4 plus (going off memory here) and it wore the inner 1". I need to re-align it with the new tires, but just haven't got around to it yet.

The OEM rear is currently at -0.9 and -0.8 after being adjusted by a reputable local suspension shop. They told me there's no more adjustment left. My performance shop says they can get it to +-0.0 or even slightly positive with one of the arms I've mentioned. I'm thinking, is traction really affected by such small fractions of a degree?
