About to upgrade my suspension, 05 Turbo S, and was wondering if
anybody out there had experience with both or words for either. Had
PSS9s on a Speedster and liked them, much better than stock. Also
have had Motons on my Viper, very nice but a bit harsh on normal roads.
Not a track car, just want it a little lower and more control in the
mountains.

RD,

My vote is for PSS9/10's in most applications especially when it comes to the Porsche 996. I have guys that run 9's on the street and then do track events almost every weekend aand all they have to do is twist the ****. If you want, PM me your zipcode and I can put a shipped price together for you.

Moton's also kick some serious a$$ however they are going to be some money so it is up to you. Give me a budget and we can go from there.

I agree, PSS9s are the way to go. They are much easier to adjust in terms of just flipping a **** and offer all of the flexibility of ride height and dampening adjustment. H&R makes a solid product as well but for the sheer ease of adjustment, the PSS9s take the cake. I would also look into JIC Cross and KW Coilovers as alternatives.

 

I just checked with my Bilstein rep and here is the deal... PSS9's have been discontinued for this car and PSS10's will be out in the beginning of 09. I already have part#'s and msrp pricing so I can take pre-orders after price is determined via PM's. JIC and KW are also good examples of suspensions available of which I am a dealer for them as well so whatever you are after, let me know, thanks and have a great weekend.

I have PSS9's on my car. If you only want it for the street, they are very good. If you want to do DE's, then they are good there also but the limitation with PSS9's or 10's is the limited amount that you can lower them {1 1/2 inches} and the springs are more for street than track. For the street, it's a good compromise because you don't scrap anything under normal everyday road conditions plus the car no longer has that SUV look. You do need to be careful with speed bumps and sloping driveways though. I cannot address the H&R's as I have no experience with them. JIC's have much to offer and I've never heard anything but good reports about the KW's, but you can't go wrong with PSS10's for your street car.

 

My experience also +1

 

When I bought my car it had H&R lowering springs on it and I while it sat really nice it did not handle well at all. It seemed like in high speed corners it would really wallow back and forth. About 6 months ago I installed a set of JIC coilovers and it is night and day. With the right alignment the car handles like it is on rails now and is rock steady in the corners. I would say go for the coilovers! Good luck

 

I have the pss10's on my car and love them, we have also installed a few other sets on 996tt's.

I installed the H&Rs back in the day when there was nothing else on the market. They have been good for street and track use. I have experienced some spring sag. They are currently set at their max HIGH ride height, and the car is still very low. I have trouble transitioning off of high banks onto the infields at some tracks, and I get inner and outer wheel well rubbing with my GT2 wheels. Also, these are non-adjustable WRT shock valving. I have talked at length with Bilstein engineers, and the PSS10 is great state-of-the-art technology, for steet/occasional track application.

 

After talking with a local suspension guy it looks like I might be going with
H&R Street Performance coil over, 1.0 to 2.25 adjustable ride height. 3k
installed. He and the H&R guy said that the adjustable valving on the
PSS10 was more gimic than anything. And he sells all systems. Imputs?

RD

 

Sounds to me like he may not have any pss10's to sell you. I turn mine all the way one way and the car rides like a caddy. I turn it all the way opposite and it's hard as a rock. I prefer the 10's for sure I track the car occasionaly and picked mine up for around $2,400 shipped to my door.

H&R's are on my turbo S cab. Not a track car for me at all just looks. The were more like $400. Car looks great but no comparison to the handeling b/t the two. Then again for 2k I hope to see that. Keep in mind which ever way you go you will likely pay $300 labor,$250 allign, possible corner balance with coilovers anothere $200ish. If I could do over I would have just put the 10's on both cars but I was on a budget with 2 pcars.

 

H&R coilovers, not just springs. PSS 9/10s use H&R springs but I don't
know much about their coilovers.

RD

 

Went through the same thought process. I picked PSS 10's - ease of price and adjustment. Get some adjustable sway bars to go along with them. This is a nice street combo and will cost less than $3,500 installed. If you plan to track the car, you'll need motons, rear dog bones, adjustable rear toe links, thust bushings, GT2 front control arms and a big check book.

 

I'm running H&R Coilovers and I'm very happy with them. People tend to prefer PSS9/10's. Just a matter of preference.

 

Any issues with ride quality on the street? How low did you go? The guy
I'm dealing with said something about the, pardon the pun, shaft length
of the PSS 9/10 being an issue and that the adjustable valving was not
meant for ride quality but for cornering issues and that the springs had
more to do with the ride.
