I didn't think Porsche did such a kit as an option, or retro fit, but may stand corrected ??
Other than that, you've got the likes of techart and Gambella etc.

The TT can be lowered 20mm from the OPC.
This makes it the same height as the GT3 (which is 30mm lower than a C2, the TT is by default 10mm lower than a C2).
I have not tried it, but it will make the ride hard. It is worthwhile if you spend lots of time on track, but for lots of road use, I would suggest the standard setup is pretty good. Losing the compliance will make it more nervous when "pressin on" on minor roads.
It will also make speed bumps and entry/exit ramps more of a challenge.
From an aesthetic perspective, I think the lower the better, but in the real world compromises are required.

Thanks Guys,
Yes Glen, OPC do a retro kit now, it lowers the front by 10mm (4 shocks and two roll bars)
The most expensive part of the change is resetting the PSM as the CofG has changed.
Its just that sometimes when I turn in to a corner, the front end seams to take an age before is reacts.
Mind you it could be my right foot .
Thanks again

James,
If that's one of the main reasons, then i would look into whether the car can be 'set up' better.
I know this can be done on GT3's etc but not sure whether turbo suspension can be adjusted ??
Anyway, if it can, then just by changing the camber of the front wheels can make a massive difference to turn in.
Having said that, this can also have an effect on the road manners of the car in general.
Are you specifically talking about track work or road ??

The code for the short springs would be different for the TT since they are stiffer than for a GT3/C2, since there is more weight (intercoolers, turbos, plumbing).
I don't know about a 10mm kit. Maybe it could be a reasonable compromise? Hard to say.
Are your turn in problems recent?
I've had a couple of times the last few days where the front was sliding due to the greasy roads (low speed T-Junctions). The salt has attracted the dampness and a few corners struggle to dry.
I'm also struggling to use full power in 2nd without spinning the wheels, but that's a different issue.

Its more for the road than the track. but I will have the suspension checked out, and find out if it can be adjusted when I have the rear tyres changed.
A little bit of history Stuart, Reg in Jan 04, 4000miles plus on the clock.
I have been to the skid pan at MIRA, and 4hrs at milbrook, the rear tyres are ready for replacing.
From what I can recall the car has handled the same from new.
I think that I have adjusted my driving style to suit, so it is only sometimes that I notice the slow response when cornering.
It was suggested that a front strut brace may help, but I have no idea if these make a difference. hence thiking about a suspension change.
I was told the other day that instead of upgrading the car, it would be better if I spent the money on some advanced driving lessons, its a thought!.

How do you mean James, is it understeering, sliding, rolling?
It could be worth having your geometry checked to see if it's to spec., TT's do run a fair degree of toe in to help keep that heavy tail in check, but I'd be careful about playing with set-ups too much for that very reason...going backwards through hedges isn't fun!!!

What tyres have you got on it?
Some have stiffer sidewalls than others.
At the risk of stating the obvious, they are at the correct pressure?
A strut brace would make it stiffer, but I'm not sure that there is that much flex in the car anyway.
Similarly the suspension bushes and joints can all be replaced with metal ones, but that will make it noisy. It may be quite expensive as well. The turbo has improvements in this area anyway over the C2 (sorry I can't remember the exact details).
What are you comparing it to, by the way?

Hi Suart,
The tyres are Michelin Pilot Sports ( N1) tp 2.5 3.0bar.
I had a 993 turbo on Bridgestones for two years, and a C4S on Bridgestones for two years as well.
I have been trying to source Michelin Pilot sports N2 as I believe they have now been recommended by porsche for road use, the report I read said that the N2 were a different construction,with a stiffer side wall.
Thinking about it you maybe right it could be the tyres as apart from being a different make, these have a lower profile than the tyres on the 993.
