Geometry Check
Discussion
No good for Andy, but can highly recommend GT1 at Chertsey (01932 569911) -ask for Peter or Craig -mention my name.
I have this done annually on my car. They also know how to tweak the settings to improve handling for road or track.
They don't do corner weighting, but if you want to go this route, take your car to Parr in South Godstone.

Melv,
I know this may sound like a a silly question, but what should the 'lay punter' look for when an outfit does the geometry (in this case a 993). I know the generl answer is 'the car should feel better, etc', but is there any way to tell how bad a car is out of alignment?. I remember reading in 911 & Porsche world about some bloke who builds/rebuilds porsches saying that he could do a geometry setup with not much more than a piece of string. Anyone have any opinions/tech tips on this?. also what is 'Autolign'? and corner weighting?

Veewhy...there are geometry settings for different models of 993.
they measure both camber and toe in & out.
Ideally a decent alignment will be done using laser from a pick up mounted on to the road wheel, data from all four wheels will be shown on the computer display.
Once set up with the measurement equipment, readings will be given, these are then compared to the manufacturers data and adjusted accordingly until they are in line. You will see how far out things were as hopefully you will be given a before and after printout to show how far out things were.
If you have RS suspension or a fancy PSS9 set up you will also be able to adjust for ride height.
here is a link to what the alignment specs should be on a 993 http://p-car.com/susfaq/alignment.html
I have had my alignment specs checked with string and it is suprisingly close, but I get paranoid if the suspension gets a few minutes out. So well worth having it done properly as i will again next week!

arwebs,
if you fancy a drive up to edinburgh, there's a guy who does it for £47 to check and adjust all four wheels.
He did my 996 recently and does all TVR and Lotus stuff in the area too.
He used to do all the Porsche OPC work up until they got their own geometry equiptment.
If you're interested i can provide contact details.

I am very interested as I am up that end from time to time, was there a few weeks ago. Does he have the kit?, or is it lolly-sticks, rubber bands a little bit of Jedi moonlighting?. Can you mail his details to me?
Club: thanks for that. I was wondering though, how a layman could tell how far out things were, the reason for this question, is because it will go out of line gradually and apart from the bleeding obvious signs that may be 'communicated' just before I start to explore the somewhat daunting outer regions of under/oversteer, it would be good to know by how much, in short are the settings at/beyond their threshold. It will be an interesting thing to do for an anorak like me, who whistfuly stares into the engine bay and wishes he could change those plugs buried down there somewhere, if only he knew what he was doing. So when people talk about pieces of string for 993 geometry, I'm thinking, well if Barnes Wallace could manage it with rubber bands and glass marbles...
G force in Aylesbury use the 2 forty gallon oil drums and a length of fishing line for a full four wheel alinement but it is in no way a cheep option it is very time intensive and usualy reserved for exotics ,neurotics or race cars.
I will probably be corrected but I think that most race teams still use this as the most accurate form of setup.

Depends who & where etc etc but round these 'ere parts its in the £100 to check & more to adjust sort of area.

there is a guy called ninemeister on this site who does the full job on 4 wheel alignment.
I have an s2 and it was all over the place on uneven road surfaces untill I replaced the tyres. Check for uneven wear before you do anything else. Porkers are delicate sensitive machines engineered to high specifications. I woud never have believed uneven wear on tyres still easily road legal could have such an impact.
I'm getting the alignment done in a couple of weeks. As far as relying on specialists only is concerned, if a laser system is used then you'll get the same result from any decent mechanic. They all love to get their hands on a porsche and take pride in doing a good job on a top motor.
