Lowering Springs and the rest

I have decided to just do Eibach lowering springs (25-30mm lowering) and new dampers/shocks (Koni Sport) for my 2004 996 C4S instead of coilovers as i just dont need super aggressive suspension for everyday driving and prefer a comfy ride. What are the other key components to change out while doing this upgrade? I have read that Strut mounts, bump stops and dust boots, control arms (or at least the bushings), sway bars (front and back), sway bar drop links with a full alignment are a must for a great new feel. If this is the case should i go stock on all of these or does anyone have recs on better aftermarket parts as I would rather do this once and properly. Thanks

Be sure to replace the top bearing under the support plate as well

** Following as I’ll need to go down this path eventually. I too think I prefer just an OEM+ solution, over an aggressive set up. Please document your process/progress @Gizmosh

If u dont need an agressive suspension then u dont need the aftermarket sway bars. Save the money and buy the rest of the arms and replace all the rubber.

Tie rods , inner and outer .

​​​​ @De Jeeper , what�s the impact of those sway bars on an otherwise OEM+ set up? Is that effect �wasted� in this scenario?

I dont think its wasted as it will benifit a stockish suspension...i just dont think he needs it. The factory bars r more then enough for street and canyon driving. I even know guys turning very good track times with stock bars. Buying a set of Feals for the cost of the bars and the lowering struts would yield a better carving car but thats not what he wants. Also, i was trting to point out that every piece of rubber in that cars suspension is ovet 20 yrs old. Its been discussed in nausium that its all timed out and needs to be replaced. That should be the op's priority. U can always add bars in the future if he wants to stiffen the car up.

Lower control arms and forward arms will really complement new struts + springs. Would probably skip the sway bars and just throw in some new bushings. I wouldn�t go cheap on any of these items.

Thanks for all the great comments. So to clarify what I plan to do: New dampers/shocks (Koni Sport, Bilstein B6/8 - whichever has the more comfortable ride) Eibach pro-kit lowering springs (25-30mm lowering) New strut mounts with bearing kits Lower control arms Drop links + Tie rods Bump stops (all 4) Any other bushings?

Do a full refresh at the same time. It is totally worth it. I went to Bilstein B6’s I think…..with H&R sport springs. The Eibach sway bars are VERY stiff and if you’re going stocking suspension you won’t like it. I put them on my 986 with stock suspension and it is stiffffff.

I did Eibach rear bar. It will benefit any set up by dialing out some understeer on middle hole. Not stiff, Goldilocks.

Are Porsche RoW springs (for a 4S) handed or do both sides use the same spring?

All the rear parts https://www.fcpeuro.com/products/por...xoCODwQAvD_BwE The front parts. U can delete the inner tie rods and boots. https://www.fcpeuro.com/products/clo...hoCZhkQAvD_BwE

Konis are more comfortable than Bilsteins. Bilstein�s B4 are their most comfortable option (and cheapest). Are you sure you want to lower your car with Eibach Pro-Kits? Doing so will reduce your available shock travel, putting you much closer to your bump stops and the end of shock travel (bottoming out). If you proceed with the Pro-Kits, you�ll want to trim the bump stops. Trim the fat end off - you�ll retain the progressive nature of the bump stops by keeping the narrow end. If you remove the narrow end, the progressive nature of the bump stops disappear and you�ll feel the crashiness as the bump stops engage.

I don�t have any direct experience with those springs, but I�m fairly certain both springs are identical (non-handed).

Bilstein B4 or Koni Special Active. The latter for modern technology that offers comfort/no crashiness over ridges, road repair patches etc. and a lot of composure/body control when canyon carving.

If you want a comfy ride skip the sway bars, mine came with Eibachs and they make the car more jittery than it should be on uneven pavement. Eibach springs + Koni Special Actives should do the trick but IIRC you need to cut bump stops to buy yourself more suspension travel.

Correct. Front and rear pairs, not corner specific. You do need to ensure the pairs have same rates. Check that they have same color paint dots on the spring spirals, themselves.

If you really want to do sway bars look into RoW M030 units suitable to your year/model. Be sure to get the matching bushings.
