Coilover owners (lowered) and computer alignments

[logray]

If you've had your car aligned on a computer, what did you tell the shop the car was most setup like? GT2, Turbo? I'm assuming the alignment computer is going to crash if you tell it that it's a stock 996.

I'm going in for an alignment tomorrow, just for toe, camber and caster. I mistakenly installed a steering wheel one spline off, and had a cheapy alignment done, now that I've corrected the wheel it's off.

It's also off because I had my engine out and also removed many suspenion components during the restoration (both front and rear). I removed one of my coilovers to repair a broken bolt, so I'm sure that is contributing to the bad alignment. I wasn't happy with the front ride height so I setup the car at 26" from ground to wheel well on all 4's (yes I know CB would change that).

I would go in for a CB but can't make it to a good shop in the bay area right now, have to settle on just an alignment.

The last good alignment I had done included a corner balance (ALL done by hand) and the car was 100% perfect.

I'm taking it to the dealer and am wondering what I should be telling them as far as specs (or what car to mimic).

I would use GT3 (996) as that would be the closest factory settings - based on weight and drivetrain.

As your car is a Mk1 - use the RoW GT3 settings.

Perhaps a silly question, but unless you are going to the track, why would alignment spec's be different for coilovers than a stock suspension? I have PSS9's and plan on an alignment next week, so this thread is very timely.

Thanks!

Aftermarket coilovers change the ride height so usually the camber cannot be adjusted to standard suspension ride height, in other words it's generally not possible to align a lowered car to original specs.

There are other suspension packages from Porsche which do allow for more adjustment and lower the car and thus the reason for my question.

And thank you Loren, GT3 seems to be the resounding answer.

Got it. Thanks Logray.
