Have decided this car is going to stay but the suspension has to go. That said, I may track the car here and there but I am going back to racing so if I did it would be just for fun.

That said, I want a solid street suspension but I am not interested in the super expensive remote reservoir systems. I think I have narrowed it down to the PSS10's and KW V3's. I have heard the Bilsteins are just fine for the street as you can lower the car and it will handle much better than stock on the street. I understand that it is not the ultimate track setup but as I said this is not an issue. The KW's seem better but I have read they are also very harsh on the street which I don't want. I would even consider the factory X73 setup if there were benefits.

I really would love to hear from people who drive with these suspensions and not die hard track junkies because I don't want to ruin the car on the street. I will be racing so this is not my track car.

Thanks!

 

I've always loved Bilsteins for the street aspect. I've driven in KW's on BMW's and the ride was also to my liking.

With that in mind, if I had to choose between the two. I'd take the PSS10 over the KWV3. Tirerack has the PSS10 for roughly $29xx and KW's usually run $37xx.

 

I would go with the PSS10 also if it was only for the street, i really liked mine on the street. They don't drop a lot though so if you are looking for a low rider, go with something else. They wil lower the car about 1". They are also cheaper.

 

Just throwing this out there, but have you considered the K-Sports? The spring rates are 347 front, and 549 rear (stock is 188 front, 343 rear) so they seem like they'd be a very good street choice.

Only a couple guys have them though, but from the few reviews I've read from actual owners, feedback has been very positive. The price is also much cheaper, at about $1600.

 

I've had the RUF PSS9, H&R coil over, and JRZ on my car. For the money, the H&R was the best street set up while still very capable at the track. It is a very overlooked but excellent and affordable set up. It's non adjustable but the shock valving is matched great for the 996 turbo. Ran mine with an H&R rear adjustable sway bar and it was a great set up. It's on my friends car now and he loves it.

 

KW V3 hands down.

Reason is that for ride quality it is a better choice to use a shock where you can dial in compression and rebound separately to your liking, for the type of roads you are driving on.

When there is only an adjustment for rebound, you can not dial in the compression settings to soak up bumps better, while increasing rebound for more sporty feeling/body control.

If you don't like the spring rates, it's easy to order a set and change at home, but if you don't like the valving you will be out of luck. Therefore, having both adjustable compression and adjustable rebound is always going to be the winner.

 

I have PSS9's in my 04 C4S for 6-7 Years now with over 150k on them. Summer, Rain, Winter, Snow, Ice, Track & Highway Runs they seen it all Daily. No issues and Loss of performance

 

+1. I have the KW V3's on my car.

I believe there are 18 compression adjustments and 12 rebound adjustments. You will find a setting that will make you happy.

Supplied spring rates are a little soft for my liking for the track, but are really nice on the street.

 

Kw's.. I had the pss9 and they sucked!

 

I think what I am hearing all over is that PSS10's are ok for the street but the KW's are just a better setup. Think I will do the KW's. I also wish the install was a little more straightforward so I don't have to pay a shop to install them which isn't cheap. The guesswork as to what parts transfer over to the new shocks is not something I want to toy with for obvious reasons...

There are several forum sponsors that stock KW's, PM them for pricing.
