Is it a problem to have almost twice as much camber in the right front wheel as the left front?
Update by David S. Wallens to the
Porsche 911 Carrera project car

The Porsche awaits its turn on the alignment rack.
Turbo tie rods deliver crisper handling.
Final result: better steering plus a slightly lower ride height.
The stock 911 tie rods feature a rubber isolator. The Turbo pieces aren’t so hamstrung, so they provide crisper steering.
Our Porsche received its new Turbo tie rods plus the required alignment. It’s nearly impossible to replace the tie rods without having to do an alignment. Since we didn’t feel like trailering the car to the shop for its alignment, Geoff at Andre’s Automotive handled the job. He has performed the suspension work on many GRM project cars and always knows exactly what to deliver.
First, why the work? The stock 911 tie rods feature a rubber isolator. The Turbo pieces aren’t so hamstrung, so they provide crisper steering. This swap is a popular performance update. Also, one of our outer tie rods was looking a bit tired. The new tie rods plus the required boots and spacers set us back less than $200.
Geoff also lowered the nose half an inch as it was a bit too high in the air. (Dropping the nose a whole inch gave the car more negative camber than Geoff was comfortable with.)
Here are our alignment specs:
Right front: 7/8 degree negative camber
Left front: 1/2 degree negative camber
Front toe: 1/8 inch total toe in
Right rear: 1 1/8 degrees negative camber
Left rear: 1 degree negative camber
Rear toe: 1/8 inch total toe in
Verdict: We’re idiots for not doing this sooner. The front end shimmy has gone away, and steering response is much sharper.
Downsides: none.

On a road car, Geoff, who did the alignment, likes a little bit more negative camber on the right to compensate for the crown of the road. The Porsche does go down the highway nicely. (Coincidentally, that was the max negative camber he could get at that ride height.)
I hope to afford this when you guys are done.
Ah, I didn't think of that. Clever clever.

Neon: Wow, cool, thanks!
PS: My tree guy does awesome work. If anyone in the Daytona Beach area needs some tree work, let me know. He's an artist.
