Lowering springs on this platform kill the ride quality. If you actually drive the car vs a weekend car, you will regret the money spend in labor and parts cost. Your mechanic isn't the one driving the car. It is jarring. A small pot hole will toss a drink out of the cup holder! When the shock travel bottoms out, the suspension is on the bump stop. And this will occur in every drive.

Save your money and purchase a used set of coilovers. I'll get off my soapbox..

obviously, that isn't my experience with the H&R springs, and i drive quickly a lot, albeit on some very tasty fresh blacktop, so that must be factored in when assessing my assessment of the ride quality of a 996t on lowering springs. i do also avoid pot holes whenever possible. that seems like good advice too. but i've NEVER bottomed out, yet.

I'm by no means an expert on this topic, but when I was researching my suspension options last year, I found a mix of opinions on lowering springs (do a search). A few loved them, but many had experienced issues described above and ended up removing them and going with a full kit.

For me this is an extremely well engineered car and I didn't want an "okay" solution on something as important as the suspension.

It came down to the PSS10 and the X73. I ended up going with the X73 because it was engineered for the car by Porsche (that's not a slam on the other kits). I think I got one of the last sets available and have been extremely pleased with the results.

can't go wrong with oem either.

where can one find a set of used coilovers for sale?

jcb-memphis

Various forums. I would not get them used unless you really know a lot about them and the history....mine were new and I just accepted the cost...
...

Tirerack has sales.

Tuners have sales or take offs when people go to motons....so call big name shops.....

Put an add in the wanted area here and see what bites.

Hi Kevin,

which would you say are better - Bilstein or KW coil-overs, I would be looking at fully adjustable damper, rebound and height.
I prefer sharper handling over comfort.

I have a 2004 996TT and it tends to under steer.

Regards

Strange....I actually thought the H&R springs were smoother than my stock springs. I didn't like the wheel gap, so I decided a cheap solution would be lowering springs. I was willing to live with the bone crushing harshness of lowering springs, but felt that the ride was actually smoother and softer.

The only issue I do have currently is that I can't clear driveways and bumps very well with the 1" drop. The other thing I don't like is the fact that the stock struts are much longer than the springs, so when the car is jacked up, the suspension comes apart.

I don't track or autocross my car, so this was done purely for looks.

PSS10 gt2 setup=pleasure to drive. Mine was fitted with stock suspension and HR coils it was pretty bad.

My car was bone stock with suspension and ride height. I found the ride in the city to be somewhat rough and downright scary during high-acceleration moments where the front end would wander. I had PSS10s and GT2 alignment and the car is much smoother on the street. Nice thing about the PSS10s is you can adjust the ride from softer than stock to pretty firm at the 10 setting. Probably good enough for a fairly aggressive track day if you wanted.

Bought my 2004 in 2007 with 48k miles. It has 58k now It had lowering splints and had a terrible ride. Soon after purchase went to PSS 9 set up took a while to get setting where I was comfortable but I have it dialed in now and car handles like slot car with a good ride. 90 % of my driving is city. No track use If you do a coil over corner balancing is a must Reserch your alignment shops you got to find someone that knows what they are doing to get the full value of your objective.
Good luck

I completely agree. I used lowering springs for about 10,000 miles, and hated them. Kevin recommended PSS10's, and they are great. Set up to GT2 ride height, with GT2 rear sway.
The settings that work for me are 2 on the front, and 3 on the rear. Ride is very comfortable, I don't ever bottom, and track performance is fine (there is no prize for lowest lap times- handling is excellent, predictable. Maybe harder settings could pick up a tenth, but so what?)
The labor costs enough that it makes sense to just buy the best solution, and don't do it twice (like me). AS

If you can find a X73 setup, do it and dont look back. Perfect for the 996TT.

olsen motorsports posts various coilover sets for sale on the cup car forum on here. very knowledgable and remember coilovers can be rebuilt to new level and springs can be swapped for softer or stiffer . simple lowering springs and your stuck with what you have.
my car came with jrz single rebound coilovers. not super high end but simply adjusting the height and the rebound changed the entire feel of the car

^ yeah, I picked up a used X73 and bilstein is rebuilding the rears now.
