I can’t seem to figure out why the front springs are not sitting properly. It is clear that the inside diameter is different but all part #s line up and make sense. Can someone please shed some light on this.

You're missing the support ring and bearing.
Did you even look at an exploded parts diagram?

 

I can't tell if this is front or rear but look at page 95.

I don't mean this to be nasty but if you tried to assemble a basic damper without knowing this you should stop and step away. No shame in this. These things can and do kill people. Consult with a pro to help you this first time.
Take your disassembled damper to a shop (any shop can do this.. doesn't need to be a pcar shop). Pay them $50 cash to reassemble and ask to watch. They'll be able to do this in 5 minutes.

 

No worries. Yes. I have the entire assembly attached. My concern was the fitment of the spring to the assembly. Seems to be a bit larger than the OEM. I should have been more specific in my description as I am struggling with the difference in the fitment of the OEM and the Eibach at the top end.

I think I figured it out. If someone can confirm that these look good I am ok.

 

From the diameter of your springs I’m assuming you have a 2WD model, I.e. Carrera or S.

Looks like the Einachs are for a 4WD model - the springs are a larger diameter at the top due to the different suspension geometry on the 4WD cars. The strut sits at a different angle due to the need to clear the driveshaft and the springs have a larger diameter.

I wouldn’t fit those to your car - go back and get the right set.

The rears will be the same so no issues there.

Hope this helps.

 

Which exact Eibach kit did you purchase (part number, and link)?

What 997 model do you have, and does it have any additional suspension options (e.g. PASM on a base Carrera, SPASM on a .2, etc.)?

Thanks.

 

If you still have trouble, H&R Springs highly recommended ----> They are made for Narrow Body or Wide Body and have 2 different model#'s.
Love my H&R's

Happy Holidays!

 

I purchased the kit for the 4wd as I have an 07 4S with PASM. Maybe that is the issue that these shocks came off a no 4wd car. Would that be a completely different shock?? The top hats serial #s check out for my make and model.

Per Eibach, the 7220.140 set you listed above is for the 997 Turbo Coupe:

They list the 7222.140 as the set for the Carrera 4:

They didn’t differentiate between C4 and C4S in the selection process, so I assume the same springs work for both.

yes shocks will be different as the front suspension geometry is different on the 4WD models.

 

Happy Holidays to you as well. Love my H&R's too and have been a loyal H&R customer for my three 997's. I know.....three 997's and a long gone orange 1971 911 T leaves me far back in the shadow of the number of 911's you've owned. What I'm curious about though are the two different H&R model #'s you mention. I always thought there was one set that worked for both narrow and wide bodies. I've just been buying H&R's and had the dealer install them. Never heard any comments on narrow vs. wide body when ordering or when installing. Can you elaborate please?

 

See following examples of different H&R springs for the 997 on Champion’s website…

Thanks to everyone’s help I figured out that the narrow body carerra and carerra S run a different spring strut than the wide body / 4wd and turbo cars. I would assume it has to do with fitment as well as performance demands. It could be the top hats only but I won’t know until this weekend when I pull the assembly from my car. Either way I might have a nice pair of used springs and struts for sale.

 

It’s not 100% clear…

Are you still planning to try and fit the 7220.140 kit (meant for the 997 Turbo) on your C4S?

Thanks.

 

I went through this with Eibach when putting springs on my 2010 Cab Turbo a few years back and found it maddening. Vendors showed different PNs that didn't agree so I called Eibach and even they seemed confused. I ended up with this:
.
7217.140: All Carrera RWD
7220:140: Turbo Coupe (AWD)
7222.140: Carrera 4 AWD, Turbo Cab (AWD)

Best I could tell is that the AWD vs. RWD front springs are different due to the different shock tower design. In addition, the Turbo uses a different rear spring between the cab and coupe due to weight of the cab top (i.e. a different spring rate). One would think the Carrera would have the same Cab/Coupe distinction but they call out the same PN.

The Eibach catalog even calls out the Carrera MT and Carrera PDK separately, but lists the same PN for both. I got the impression they started out with a whole bunch of variants (particularly based on rear mass - PDK, cab) but then just gave up and narrowed it down to three choices and assigned whatever was closest to the model.
