Default What springs/shocks do I need?

Hi All. I need expert advice. Read all of the threads and I am still confused as t what to do.
My 95 C2 has the original US ride height springs on it but the shocks were replaced with Bilstein B6. I'd like to have the car lowered to ROW ride height and am looking for a nice compliant street ride with a little sporty edge.
What is my best option to do this? Are new springs required to lower the car? (I assume yes) If so, which ones? (M033?) Would I want to keep the Bilsteins? Does Porsche provide any springs/shocks more modern than the stuff they provided in 1995 for the 993?
Pic of my baby below.



Thanks in advance.

M033 ROW would be a good solution if you want to keep your ride the same and keep the Bilstein B6s

Hi 997AT,
Look under your car if there are remaining threads on the barrels of the struts below the spring perches, the ring the bottom of the spring sits on, the car can be lowered with the current springs and struts.
If this is possible I would do this first. The limitation is that the lowest setting while retaining the factory alignment settings is 30mm below the USA height. Lowering the car will change the impression of feel to some extent. Because of this, I would just lower the height before investing in replacement springs. Also, folks such as H&R sell aftermarket progressive springs that have desirable characteristics for some. If you do not go below the ROW lowered height you can reuse the stabilizer drop links. Sometimes the grease boots on the drop links are dried out and cracked. If they are and the link ends themselves do not have play. New silicone rubber boots can be purchased for a few dollars to replace them.
Also, if you end up taking off the OE springs or really any other suspension part, hang on to them because a future buyer of your car may want them.
Here is a page with a ride height chart you may find useful:

Hi Andy. Super helpful, thanks a ton for the info. I went out and snapped a few pics (below). It looks like I have quite a bit of threaded area remaining. If I can simply drop using the existing springs and the B6 shocks that seems like a great way to go for me.

This is exactly what you need to do and then get a new alignment once you are happy with the ride height.

I went with the M029 (ROW Standard) which is about the same spring rate but 10mm higher than M030/M033 and couldn't be happier for a street car. Springs and shocks purchased from Carnewal.

I went with PSS 10s all around and a proper 4 wheel alignment, I am very pleased with the look and drive.

Best

I lowered my US spec C2 to ROW ride height with B6XT. If you like the way it rides currently then you can easily adjust the ride height by lowering the perchs.
