I just completed the rear 944 suspension swap on my 924, but it looks like I have a bit of positive camber in the rear. I had adjusted the trailing arm to lower the rear a bit and I don't see how that affects angle. Of course, I did just set the car down and haven't driven it yet, so the tires are expected to be tucked under a bit. But it seems excessive.
Is there a way to set the car for negative camber in the rear?

Sure, I run 2.15 deg neg camber in the rear of the racecar using the factory adjustment.

Make sure you haven't confused the camber/toe adjustment (3 small bolts that attach the trailing arm to the spring plate) with the ride height adjustment (2 large bolts on the spring plate itself). This is a common mistake.

What size wrenches did you use to make the adjustment???

Vaughan, thanks for the info. I think I adjusted the ride height by messing with the toe/camber adjusting bolts. I looked at another subframe I have and see the offset bolt for ride height.
Now, how does the toe/camber adjustment work? If I loosen the three bolts, I only see the trailing arm moving up and down a little. Is that actually changing the camber as well?

Yes, moving the trailing arm up and down at those 3 bolts does affect the camber - pointing the arm all the way down gives you max positive camber (about 2 deg), and all the way up gives you max neg camber. Be aware though, that you can also move the arm forwards and backwards at that spot, thereby changing the toe. Moving in one direction also usually changes the other. Change the toe without paying attention, and the camber will usually change on you, and vice versa. This is why you really need it done on an alignment rack. Additionally, there's an inexpensive ($1 tool from the factory that fits into the trailing arm that allows you control of the toe setting (it's an eccentric). I have it, and use it, but I also have access to an alignment rack at work!
