Default C4S lowering springs: what else while we are at it?

I am in the process of setting up a .2 C4S with more aggressive suspension. The stock PASM isn't the greatest. I want to start with lowering springs to reduce that gap, but while I am down there, what else should I add? What is a good bang for the buck? My last car was a 991.1 with SPASM, and I loved how tight and flat that car felt. I don't want to spend a ton, but often $1500 or $2000 on suspension components goes a LONG way

Other mods I am considering:

-DSC module

Someone is going to ask me "what do you want to use the car for" so pre-emptively, the answer is: everything. I want a tighter all-around feel, as it is quite the floater at speed. I don't need GT3 RS hardcore, but firm, tight, responsive suspension if my aim, aside from losing the 4x4 wheel gap. My other car is a 2002 Tacoma with stiffer leaf springs and Tundra struts, so it is a firm ride. I am sure whatever we do to this car still won't be "firm" like the Taco; I have yet to drive ANY porsche, even a 997.1 GT3, that is as firm as my older truck, and given that I put 30k on that truck a year, I figure whatever we come up with here won't be a big deal.

FYI, I once had a 997.2 with the optional B8 sport struts and H&R springs. It was fine as a daily, but at least 50% firmer than the stock struts.

Most people speak highly of the DSC.

Eibachs definitely improved the handling on my .1. I think Eibachs + 10/15mm spacers front/rear are the ideal stance for the 997. I get compliments from everyone and its one of my favorite mods.

"While you are in there", I would replace the strut mounts and bump stops. Also a good time to do brakes, brake flush, rotors and/or clean the wheel wells and calipers. And inspect your front fender liners where the brake vents and underbody panel meets. That area can get abused. One of mine was cracked, the other had chunk missing.

I've got a DIY writeup on it but it doesn't cover the C4S. I think your fronts are a little more involved.

For the front you also need to unbolt the driveshaft from the front differential, either at the diff or at the wheels. Personally I think it's easier unbolting at the diff. Otherwise, you will not get the clearance you need to R&R the shocks.

H&R springs are my vote ---> Mine has them and car not only looks great but handles much nicer and allows for the PASM to be used if desired.
