Default What do I need for a proper rear alignment for lowered 996tt?

Well I'm on my third set of rears on this thing since I've owned it... all wearing out the inside edge of the rear tires EXTREMELY fast, while the remaining 80% of the tires look nearly new. I finally got my head out of my butt and researched that it's probably a toe issue due to the camber and toe not being able to be set with the lowered height. So what exactly do I need to get for the rears? Just an adjustable toe link kit? What brands should I look closely at? I'd like to take care of this sooner than later... wish I would have realized it a couple thousand miles ago. (mad face)

You can add adjustable parts but I still think you can get a good alignment with stock parts. I'm extremely low heightwise with coilovers/sways/adj. links but everything else is stock. -2.5 camber in rear and decent toe in. I have very even wear. This is all street driving... You might want to get a good shop to do a good alignment

Setting wise, check here: https://rennkit.com/rennkit-home/996...als-brochures/. After measuring new ride height and setting up alignment, perfect rear tire wear without aftermarket parts.

If you are lowered you most likely cannot get both camber and toe set properly without a toe link solution. Ether new adjustable toe links or installing eccentric bushings in your current toe rods. Call the guys at Elephant racing, they are smart and happy to help.

My solution was adjustable upper dog bones. I removed a rear wheel and an upper suspension link, took some measurements. I then sketched one that was adjustable and made from common sourced race car hardware like rod ends, threaded tubes, jam nuts. I used the 'net to source parts and made my own. I did a drive way alignment that was good for a quick hands off the wheel at 130 MPH, then 2 weeks later had a pro align. Car handles terrific and wear is acceptable, with the negative camber the tires will still wear on the inside edge. Same with my stock ride height previous C2 and with my current Boxster.

the "squat" of a lowered and moderately higher HP car will exacerbate this issue. while it will always be an "issue"? it will be mitigated dramatically by these http://www.torquesolution.com/product-p/ts-por-003.htm and a proper gt2 ( or x73 ) alignment. + or -.

I just installed H&R RSS coilovers with an adjustable toe links in my 2003 996TT, but found out that the camber was out by -3 degrees (was looking for -1 degrees). Tarett adjustable upper control arms (dogbones) did the trick, allowing me to gain more camber adjustment. I also replaced the LTCA bushing with their solid bushings. Not cheap, but it's now aligned to GT3 specs/height, and performing brilliantly.
