So next year I'm going to tackle the suspension on my C4S.

I'm down to either the X73 or the PSS10. Both will cost me close to the same amount. I'm interested mostly in road courses. It is a daily driver (fair weather only starting next spring) but I really don't mind harshness.

Currently, the only mods on this car are:

Wevo SS mounts
Stage 2+ clutch kit with LWFW
Fabspeed 200 cel sport cats

I'm running 18s...and plan to stick with 18s.

From what I understand, the PSS10 will give me more adjustability? Correct?

The X73 is Porsche genuine and was developed specifically for my 911 to be competitive in motor sports. (marketing or truth?)

On a side note, is the GT3 sway bar really the best option for my car?

Thanks

I loved my PSS9s on a 03 C4s. They were perfect for DEs and a better ride than factory on the street. My tech recommended them over the Xs.

The X73 is a plug and play unit which will give you years of enjoyment and is/was a true Motorsports package. The PSS10 set up will be as good with the advantage of adjustability (if you use it... many never change the settings). The GT3 sway bar is a great option if you are (again) going to use it (take advantage of the adjustability) if not save your money and either use the X73 sway (which is the same as the RoW kit) or just go with H&R/TRG or another sway bar...

If you want to go one step further why not try the new offerings from Lex... The MCS shocks with Eibach springs... Now that is a sweet system.

When you get ready give me a call and I can help you with what ever option you go with.

Merry Christmas

FWIW, I was asking myself the same question last summer. I did a lot of research and was about to pull the trigger on a X system when I ran across a used PSS setup. The price delta made it an easy decision. After 3 track days and 11 DE sessions, I could not be happier.

That said, I don't think there is a bad decision here. Go with your gut and you'll be happy.

Thanks everyone.

I really want the adjustability...so come spring, I think I'll get the PSS10 with GT3 sway bars and LCA. That seems to be a popular setup at the track. (and therefore, more people familiar with various setups)

Cheers

Chris, the MCS is a nice system, but it's almost double the price of the PSS10. If I end up getting competitive, I may be upgrading in a couple years

LC MotorSports

Sean, I hear you... If an when you start looking at PSS10's give me a call as we carry that system as well and might be able to work some pricing for you. Have a great Christmas holiday.

A word of caution . . . you might find that the stock PSS10s are undersprung when matched with the stiffness of GT3-type sways. Combined spring rates are something like 255 F / 515 R. That may or may not present some unwanted handling characteristics. The PSS10s are a terrific units for the street and track, if the rest of your suspension set up remains dialed back a bit. Ask me how I know . . .

Having said that, and since I'm diving deeper into the rabbit hole, I'll be replacing a lightly used set of PSS10s this winter--you could get a great deal . . . hint, hint.

Does anyone use KW or H&R coilovers?

Advantages/disadvantages versus the PSS10?

LC MotorSports

Sean, you should drop Aaron a PM and work out a deal with him on those PSS10's.

seanmcr6

He's got a C2 correct? Pretty sure those won't fit my C4S....

LC MotorSports

The pss10's will fit

I am getting Moton Street Sports. May be another alternative to look into.

I'm not sure many will argue that the PSS coilovers could use more spring for the track, but they have effectively the same rates as an OEM 996 GT3 so I'm not sure I understand the argument of the bars not being a good match to the coilovers.

The issue you have with the front GT3 sway on a C2 is the mounting point for the drop link in the OEM location on the pinch bolt is all wrong and creates some geometry issues with that front bar. With a threaded body coilover on the car you can use Tarett's solution to move the drop link to the correct location and everything should be a very good match.

Still not enough spring for a real track rat, but a good compromise.

Does H&R make their RSS Clubsport coilover for a C4S? I had them on my old C2 and they offer 2x the spring rate (450/900) of a PSS10 making them a great choice for a more focused application without breaking the bank.

hi Aaron, I just purchased a '97 993 Targa and will upgrade the suspension to PSS10s...what are you offering for ur set please?
