You MUST do this modification! It is worth every penny!

My 91 C4 had been riding on factory springs for its first 67K miles and I thought it was time for a change. In addition to the aesthetic improvement, I thought it would be nice to finally eliminate the wild rear squat I experienced every time I applied "a little" pressure to the accelerator.

The front setup was extremely stiff, however, so I was somewhat torn. New spings are stiffer, (right?) so this might worsen the situation. Also, the shop I used wasn't cheap, so I needed to make the right decision to avoid a costly mistake.

Well I'm glad to report that everything turned out beautifully.! The Eibachs delivered as promised: firm but good for everday use. Evidently, the preload on my front springs resulted in a stock set up which was actually stiffer than the lowering springs. And boy, does it look cool.

So get rid of that SUV look and drop your car to a proper ride height--you'll be so glad you did (oh, and make sure you consult with a Porsche automotive specialist before taking the plunge).

Here's how it turned out.

 

Great lloking wheels, what are they?

The car looks really cool. Which type of Eibachs were used,is there just one kind of lowering spring from them,are they progessive? Finally are they 17" or 18" wheels you have?

 

The wheels look to be the factory "Sport Classics", can't tell if they're 17" or 18" though. Nice looking car Joey!

 

Thanks for your comments Steve, Malc and Jeff,

You are correct, Jeff, those are BBS Factory 17" Sport Classic wheels from Wheel Enhancement in So. Cal. They were on sale!

Fronts: 993.362.124.51 7x17 with 55mm offset
Rears: 993.362.128.51 9x17 with 55mm offset

The lowering springs are the Eibach Pro-Kit 7201.140; I believe this the only kit they offer strictly for lowering. They are progressive and lower the front and rear 1.3" and 1.0" respectively over your stock springs. The shop I used actually lowered the front a full 2.0" by further adjusting the collars on my factory shocks. Of course, these modifications were followed by an alignment and corner balance.

Hope this answers your questions. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

 

At least here in Holland those wheels are no longer available. I'd ordered a set (actually from 993 Tequipment) but the dealer got back to me saying they can't provide these wheels anymore. A pity actually; they're rather inexpensive, around 1800 Euro including tires.

 

Looking Good!

 

Joey,

Your car really looks great. Have some questions

Did you had to buy new shocks aswell ? Is the suspension "comfort" still the same as with your stock suspension equipment ? Can we know what the total cost was of the upgrade ?

Thanks very much,

WSP,

In response to your questions.

- I stayed with my factory shocks. New shocks are not required for this modification but many recommend such a change.
- The comfort is actually BETTER than before. My stock suspension in front was extremely stiff and the car rattled over every bump. Now, I still feel the bumps but it's noticeably softer. Also, I have eliminated most of the rear squat which resulted from rapid acceleration.
- The labor on my upgrade was 10 hours (multiply by your shop's hourly rate to determine labor total). That included removal and installation of springs, ride-height adjustments, alignment and corner balancing. The springs cost $350.

Good luck!

 

Thanks Joey,

you convinced me to do the same. I'll have the shocks replaced when needed.

Once again nice car you have congrats
C ya later

Joey,

One more question before I am fully convinced to begin with a spring upgrade in combination with original shocks. I would upgrade the suspension purely for esthetic reasons by the way.

Do you have that bouncing/floating effect whenever you hit a bump or are touring on a bumpy road ?

I had this effect with a H&R springs mounted Audi A6 Avant. Originally shocks.

The car began bouncing once I hit a bump and was floating around on bad/old roads.

I know the combination of new springs and shocks is a better option but as I said : purely for the looks !

Thanks again,

WSP964

 

WSP,

What happened? I though you were convinced? Yes, I know this is a big commitment and you definitely want to be sure--not a problem.

First, there is no "floating" sensation with my new or old springs. I was trying to describe the recoil caused by the bump--no subsequent motions or floating. Secondly, my ride-comfort comments pertained only to my experience on bumpy roads at moderate speeds, 40-60 kmh.

The car has always felt quite comfortable at higher speeds, 60-100 kmh, but I ofen travel on bumpy roads so that was foremost on my mind. I was concerned that maybe the new springs would be bang harder on the bumpy roads, but that has not been the case.

Anything else?

 

OK, now I am fully convinced. I'm going for it.

Thanks for your help n patience. I'll let you know and will post pictures as soon as I upgrade.

C ya
