Guess is that you need both OE (non-sport) shocks and springs, which is prob. a $3000+ US parts and labor job (do your own conversion). I would doubt that just a height adjustment would accomplish much, but you can always try that first if the shocks are adjustable (at prob. $500 for labor). Jack up one side, remove the wheels, then look to see if the lower spring mount on the shock/strut has an adjustable height mount.
Another idea would be change the 18" wheels for 16".

Your best bet is to take it to a decent independent who can tell you what is on it now and what needs replacing to get it back to standard.
When it was lowered it could have had the following parts changed
4 dampers (aka shock absorbers in US)
4 springs
Front anti-roll bar (aka front stabilizer in US) and front drop links.
Rear anti-roll bar (aka rear stabilizer in US) and rear drop links.
If its had a proper sports suspension installed then all the above will require replacing to revert back to original. My guess on parts would be about 1000 pounds and then say another 800 in labour to do the reversion (off the top of my head guess - get an independent to give you a more accurate price). Just upping the ride height (if the current setup even has this facility) will not change the harshness.
Oh BTW you should then have a proper 4 wheel alignment done.
Changing the wheels back to 17" does make quite a difference. I had 17" on my car, put 18s on and immediately took them back off again because it made the ride harder.

Since you're down in Brighton, you're not that far away from Porsche specialists, Parr, up at Gatwick. I'd give them a call as they have excellent facilities and reputation for doing suspension work and frequently race and track-prep customers' cars. They would probably have a set of 17"s lying around that they would be happy to trade with your 18's including cutting you a deal on the other bits that IanUK mentions. Are the 18's you have turbo twists?

Are you certain it's the suspension and not the seat? I can ride in a nice sedan with a really soft suspension and come out with a sore butt and back if the seat isn't adjusted well. I've also driven 500 miles (San Diego to San Francisco) in my track car with a really firm suspension and been fine beacuse the seat was good.

Must have been written in another time... nowadays Brighton is England's Cape Cod.

Dear Zoom Zoom,
Yes they are 18's turbo twists alloys, they are 265/35 rear 245/40 at the front. I have new rainsport tyres fitted all round, have only covered about 3K. I have heard the P Zero's are the ones to go for, out interest what have you got fitted to your blue 993?

By the way someone did suggest that I put a pillow under my bottom while driving, I am 6'3 and the head room is just about ok, so thats not an option, as the the seats, the 993's are very comfortable. I must say that my previous car was a Porsche S2 944 Cabriolet and the ride and seats were in a different league to the 993, of course performance was not on this scale. Handling in the 944 because of the 50/50 weight distribution, gear box in the back and engine in the front, and of course all this weight between the front and back wheels!!! meant for very close 10/10 driving.
Someone did say to me that you hav'nt not driven a 993 until you have had the backout.... Anyway I am drifting again... My girl friend has bought me a birthday present - track day ticket to GoodWood later this year, has anyone been?

I have the 17" Cups with 205/50 P-Zero Direzionale and 255/40 P-Zero Assimetricos. So far, no complaints except that I would prefer more front end bite (the C4 understeers more than the C2). If you are planning to get a set of 17" and looking to sell your 18's, I know of someone who is looking to buy a set dedicated for track use. If you are interested in selling up, I can PM you his details.
