0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Reported cause
This was due to the fact that the 02-04 cars are heavier and the shock rates were adjusted to thoes values.
Leading evidence: 'fact' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'fact' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Recommend (by rennlisters) alignment shop in l.a' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

The C4S is probably a little stiffer due to weight.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Which is the better setup guys... the Bilstein HD + H&R springs or the ROW 030...?
I don't plan to track the car much... maybe 10%.
thx

x74 and m030 have the same uprated anti-roll bars, but allows a greater range of camber adjustments. it is lower, but besides improving mech. grip, it looks so cool. i saw a comparo in a german rag that pitted a 3.4 x51/x74 996 against a mk I gt3. their times at hockenheim were very close.
Expect the H&R to sit about as low. They lower about 1 inch to 1.25 inches. The X74 is suppose to be 40mm which is about 1.5 inches so the difference is 0.25 inches. As far as which one is better between H&R and M030 the H&R has a slightly stiffer rate so they will be a little better. The sway bars do make up some of that difference. My suggestion is the M030 if you don't want it too low. Given the same bars the H&R has the slight advantage, but I'm not sure how will it compare to the X74.
I spent a LOT of time analyzing suspensions for my 04 Targa before trading it and, despite concerns about low ride height in L.A., I finally decided to go with X74. Look at Gert's site and the comments from other owners on his site (carnewal.com) (most comments quoted from rennlist, I think). I also had a long talk with Gert before deciding (super knowledgeable guy!). Gert also has new pricing on X74, I think its E1,595 including shipping now. I had it on order but canceled when I got the 997S.
The lowering you get with the M030 is pretty minimal...
The X74 package puts it closer to GT3 ride height.
photo of GT3 just to give an idea
I would go with either the M030 or the X74 simply because they are factory matched shocks, springs, and swaybars.
X74 is not recomended for the '99-01 as per factory. This was due to the fact that the 02-04 cars are heavier and the shock rates were adjusted to thoes values. The difference in weight is minimal (less than 200lbs) and the parts will fit. If you like the X74 use them on the earlier cars as there really is no problem with using them on earilier cars.
ok... the X74 sure is low.... ROW 030 height should be stock one very porsche.. it just "looks right"...
is it difficult to perform an alignment once X74 is on... reason I ask is cause my buddy dropped his A4 with a koni kit and they couldn't get it on the machine for proper alignment!!
CJ,The C4S is about the same as M030, probably slightly different springs to account for all that excess weight!
Sloth I still think you had one of the best looking C2s around.
No they are not. The C4S has different spring for ROW and US versions. The C4S are a stronger spring rate than both a standard C2. They are on par with the M030 as the S means Sport. The C4S is probably a little stiffer due to weight.
I am aware of a highly recommended (by rennlisters) alignment shop in L.A. that only charges $250-350, but my dealer had quoted me something more like $800. If you can find a local non-dealer Porsche shop, I expect you could save a lot.
