Awesome update. This is one of those OP delivers threads with extreme follow up.

Mike - great looking car.

I just wanted to thank you for an excellent thread. Even though I went the TechArt spring route, your measurements and photos helped me tremendously in making my decision (particularly as I have the same style wheels). FYI on mine I had the wheels painted black and the silver lip created with a lathe. Definitely my favorite wheel for the 997.

My measurements and pics for comparison are here:

Does anyone know the parts number for these springs for a 2006 c4s cab with pasm? I keep looking but have seen 29188-1 and 54097

Thanks

Just call/email Champion...http://www.championmotorsport.com/Se...ts.asp?Cat=261

Thanks, I sent them an email. Their website which you linked only show the non pasm springs which is 29188-1 so I think the pasm model may be 29181-1

However H&R shows the pasm springs as 54097 and since they are the manufacturer, then that must be it

Thanks Perk 10

Thanks Rob.

Nicely done EMC2

Vern, Im guessing you got this sorted by now. Sorry I just logged in today after a looong time. I would think that C4s with PASM is the same as the ones I got...

Very nice photos and write up by OP
I swear by H&R's

Groove so maybe your car did only drop about 1 inch?

After reviewing several H&R postings, looks like the 997/997S & 997C4S H&R's come in 2 models - a 1" drop and a 1.2" drop
I think my car had 1.2" but since PO did the work, I never found out

sandwedge

I think you're right but I would call to confirm. Very knowledgeable and helpful staff there. No affiliation other than having bought cars and parts from them.

I used Eibach's as opposed to H&R's was due to final "broken in" ride height. IIRC it was the difference of 1/2" or so.

Chris M.

Did you replace the upper strut mounts or rear toe links when you installed the springs or are you still running the stock ones?

Sporty

The rear went up by 5/16 inch after settling??
