MY02 Carrera 4S suspension

[CO996C4]

Anyone got suggestions on lowering my 02 9964S? I know these cars come with the larger sways of the turbo so would I just need springs? Struts? Do they make a factory lowering kit for this car? AFtermarket? Thanks for any advice!

Jim,

I've been researching this for a while and I'm leaning towards the ROW suspension for the C4S for my nearly daily-driver. There are several options.

1. Factory ROW Suspension (-20mm front, -10mm rear)

2. Factory X73 Suspension (-20mm f/r relative to ROW)

3. Bilstein PSS9 / H&R Coilovers (adjustable)

4. H&R / Eibach Springs only

ROW: I believe it has the same spring rates as the USA suspension, just a bit lower all around.

X73: I think the X73 would be too low, since I already scrape the front, and also too stiff with the roads here.

PSS9: Fully height adjustable and many people say that it rides better than stock. I think this option is the most flexible with the adjustable compression and rebound, but I don't think I really need that and frankly, I think I'd get the settings wrong.

Springs only: I've been tempted by this because it is by far the cheapest solution. I've read that it is best to use matched springs/shocks, and with springs only, you're operating the shocks outside of their normal range. Some say the shock life will be shortened dramatically by doing this.

Pretty much what I found out too. And I agree, don't want to make it too aggressive or expensive.. not tracking this car. I was thinking of ROw too but the C4S already has tte bigger sways so maybe just the struts/sprng combo. Thanks

Helps solidify my choice.

The RoW spring rates are NOT the same as the USA ones. Close but not the same.

Well I am also thinking the X73 suspension.. Does it lower more than an inch? Justin at Brandywine Porsche recommended tha option.

If we assume the numbers above are correct, then yes, it does lower it more than an inch. It will be -40mm front and -30mm rear, which is 1.57" front and 1.18" rear. I believe all of these measurements are +/-10mm (+/-0.4"), so it could be a bit less, or a bit more.

I saw one post on Rennlist from a guy that was selling his X73 because it was too stiff for him. He made a comment about "too stiff for my old bones", so I'm not sure if it would be too stiff for me.

You might want to try asking around here and other forums to see if you can get a ride in a car with X73 from a local owner.

I'm about to do the x73, I'll post the results!

[ScottW]

Cool! Please try to get before and after measurements as well as pictures.

Well I got the Row M030 struts/springs from Andial. Keeps original sways. Should not be too wild. Lowers 10 - 12mm and a little stiffer spring rate. We'll see how it goes. Had to keep it streetable for the wife ya know!
