Default Eibach lowering springs set-up...

Guys,

My 2007 Targa 4 could need a little drop as you all know 4s sit higher than non-4s.

While I would like to lower the car for looks, I am looking for a way to lower it just enough but not too much, since I have a fairly aggressive slant at the beginning of my street and I can ear the lip under my stock bumper rub the asphalt as I am entering my street. I have tried entering at different angles and it rubs a bit if I approach as little too fast. The recent addition of wheel spacers seem to have helped the rubbing.

With this said, my searches found that the eibach springs only lower the car 0.8 inches which is less than other companies and why they interest me particularly.

Question is: If I lower with Eibach springs for a 0.8 inch drop, do I need to change anything else to keep a good suspension geometry despite the minimal drop or are there enough adjustments to compensate for such little drop that could be dialed-in during a wheel alignment ????

Yes I did search quite a bit, but need an answer to my specific question and would like to know if new experiences or opinions can come in handy.

Thank you as usual for any input,

Steph

Oh wow, that is great. Would you have the part number to your exact springs ??

Pretty sure they were 7222.140. Subtle drop but sufficient for the crap roads out here. I did not use spacers.

I went 10 mm spacers in the front, 15 mm rear, with a nice subtle drop. No issues with alignment using stock components.

Thanks guys, yes 7222.140 are the springs I am about to order. Just giving a local guy an opportunity to beat the price I have so far. If I haven't heard about him by tomorrow pm, I'll be ordering them.

And just last week I installed spacers. 5mm front and 10mm rear. I am very satisfied with the looks enhancement they provided and looking forward to complete the look with a small drop.

This place is priceless. I learn on a daily basis and there's no price for that.

Always thought it was the other way around. Non S cars sit higher than S cars. Eibach/Techart drop is about 1" even while the H&R drop is about 1.25". To each their own but if I had a non S car I would go with H&R's plus 10mm spacers up front and 15mm for the rears. Lots of different opinions on this subject. Picture of a non S 997 attached. As you can see it needs all the help it can get with that wheel gap.

I think he meant that the awd cars sit higher than 2wd.

The confusion is that he made the 4 plural with an s, and not an apostrophe-s. His way is correct, BTW. I hate it when people use an apostrophe-s to make things plural.

Eibachs are great. I think they are the perfect stance for 997s. I get compliments from everyone. They also improve cornering pretty significantly. I have a base C2 and the tail could get upset when hitting bumps I high speed corners. Post Eibachs it corners on rails.

I put 7mm on the front and 15mm on the rear. I think the 15s were perfect on the rear but 7mm is too little on the front. They still feel a bit tucked in. I would go with 10 or 15s.

I have a writeup on the install here:

Good luck.

You are on the right track. Proceed with no fear! I have a 997.2 C2 and will be installing TechArt springs (manufactured by Eibach) and 7mm/15mm spacers, as well as front and rear H&R 24mm sway bars. No adjustments to suspension geometry are needed given modest drop of just 20 mm, you can reuse factory drop links. Good luck and I will be posting pics of my project soon.

Yes. Another reason of going with TechArt/Eibach springs is that you can re-use OEM shocks. I will say its probably worth assessing your shocks. If they need to be replaced I'd seriously consider getting coilovers for a slight premium over replacing shocks and springs. I have just <22K on my car so reusing all OEM parts with springs.

I was so torn on the Eibach vs H&R that I ended up buying both sets of springs.

Rennlist Consensus is:
Eibachs - most similar to stock ride, modest lowering, front is 'perfect', rear is gap is too much.
H&R - a little more firm, more aggressive lowering, front is 'very low, rear is 'perfect'.

Having now gone with H&R, my view is different. I was surprised at how modest the H&R lowering is. I would definitely have been disappointed with the Eibachs in this regard, and I am definitly not a 'slammed' guy, I have to deal with terrible road in Houston. To fix the low front end of the H&R's I had a 6mm compensation plate installed in the front, and nothing in the rear - the car sits perfectly level now. I also went with larger tires (245 and 305), which further reduces the wheel arch gap, while simultaneously giving me a small increase in ground clearance. Regarding ride quality, H&R are perfectly fine with PASM. I installed DSC and have excellent ride quality - still firmer than stock, but with excellent rebound for daily driving.

I used Eibachs for AWD 7222.140 for the same reason most. Not too stiff, not too low, and still some what compliant for daily driving. Alignment done after install was same as stock, or if your alignment center has the specs or the Porsche Sport springs, that could work too since it is a similar 20mm drop. There have been lots of threads about it, but I always say and HIGHLY recommend you freshen up and install new front motor mounts, suspension strut bearing, and bump stops.

If you think about it the springs in the rear need to be able to support the engine weight so they are a bit stiffer. To be honest, the first days/months with the Eibachs the fronts look great, but I thought the rear could look a bit lower. Wheel, tires, spacers make a huge difference too in the look and feel of the stance and wheel well gap. After a few months the Eibach springs settled a bit more in the rear and to me the rear looks perfect now.

H&R is great too and the rear height looks better on day one, but you have to consider the settle in period and for me after the settle in period on the H&R's they look a bit too slammed for my liking. If you are concerned about front end driveway scraping.. that's gonna leave a mark regardless what you use, but the H&Rs are definitely lower all around.. I have to go in driveways at an angle too because I have a lower front lip, but you get the idea.

Since you have a AWD widebody like me, I also highly recommend Eibach REAR ANTI-ROLL Kit (Rear Sway Bar Only) Eibach Part# 7217.312 Rear Sway Bar is Tubular and 3 Way-Adjustable. 25mm .... basically a GT2/GT3 rear sway bar and the bushings required in order to fit fatter rear 25mm sway bar. Porsche Part # 997-333-792-95
