It's really nice to be pulling out of a drive at about zero speed, optimally angled, waiting for that crunching, scraping, dragging sound....and never hear it
Just looking at your car, my front end is lower than that and you seem to have modified your front bumper and you have lower profile tyres and larger wheels, I will take pictures and send tomorrow, I'm sure it's probably the bad front shocks because I bought the car with profile 40 tyres and the front end really should not be that low.

Thanks. Wheels are 19s (Champion RS171). Front tires are 235/35. Suspension is Bilstein B16 Damptronics with Tarret monoball top mounts and the AirLift assemblies at the top.

How much did the whole setup cost you and where did you buy them from?

I had been amassing parts to do it all at one time for quite a while as they would come up for sale on the forums. The complete suspension project included.
  • Full RSS Stage 2 setup - Rear Dog Bones, F&R Toe Kits, F&R Lower control Arms, F&R Adj Sway Bars with Adj Drop Links, Semi-solid motor mounts (some new / some used)
  • Cargraphic AirLift (used GT3 version I had to modify for my C2S)
  • Tarett Monoball Top Mounts (new)
  • Bilstein B16 Damptronics (used)
  • Thrust bearings for the Front Bilsteins to prevent binding & popping (new)
  • smaller Optima Battery (new) to make space in the battery compartment for the AirLift control box & compressor (wanted everything hidden beneath the plastic trim panels to preserve storage space and keep it looking stock)

All of these together added up to about $10,000 in parts and I did all the installation work myself so there's no labor # in there. Also added the TPC DSC kit (also not in that #) and the car is comfortable, yet handles unbelievably. Turned out just how I hoped it would. These mods were done back in March 2014 and the DSC controller added in September of that same year.

Here are a few pics and good luck with your project. Let me know if I can answer any questions. If you want to email me, my address is [email protected]

Hi All,

Just returning to say thanks to everyone helped out with my ground clearance issues and let y'all know I've sorted it out.

I got a set of lightly used stock C2 shocks from ebay for $700 all four including the springs, so I just did a direct swap, for the front I added 6mm compensating plates in addition to the 3mm one's that came with the shocks, ground clearance and ride is perfect now for these bumpy roads.

Thanks again y'all!

I can't believe I'm reading a thread about lifting a 911...
If it's that much of an issue, don't daily it on the bad route.

That would mean not owning one at all, not a chance! The roads are generally not too sexy in my country except some of the highways, and absolutely no tracks, but gotta have me my 911 fix. Either way, it works super for me...

I recently changed the wheels on the car and changed up from OE tire spec. I went from OE spec to GT2 RS tire sizing. My reason for doing that was threefold. Getting wider wheels, OE spec had a slightly stretched look I don't like, and to fill in the wheel gap just a touch. No desire to move up from the SPASM to an aftermarket setup just yet. A fringe benefit of that has been just a few mm difference in absolute ride height. I'd imagine not more than 5mm, if that. But its just enough that I don't scrape on that one spot on my way to the office anymore.

Something to consider.



edit;

just realized the poster above me is necroposting

Hi, new 997 GTS with SPASM here too.
Like to confirm you are running.
Front: 245/35-19 19X9
Rear: 325/30-19 10x12

Without problems of touching the fender or control arms?

Thanks

I run 18s for my track wheels with tires that match that sizing on 19s. No rubbing and even room for a 5mm spacer in back. This is with 8.5" backspacing and 51 ET. Hope that helps.

I was just going to say, on my other car, I did the lipectomy. It really does seem designed to do no more than slow you down for fear of making awful and embarrassing noises. But there's no more front end scraping now!

Good afternoon, I installed in the springs "air cylinders"

This allows me to adjust the height of the clearance

I put myself the first option, but there is more

v.2

Hi all,

I just wanted to add that there is a very cheap solution to this.

I installed 1999 996 C2 front springs on my 2005 997 C2S and now both front and rear gaps are same and I don't scrape my aftermarket GT3 front bumper (with lip) anymore.

I made a video on how to do it:

Hope this helps someone to save hundreds of dollars they can use for some other mod

Glad you fixed your front. Be aware though that Porsche intentionally sets up the suspension with a rake - the front is slightly lower than the rear - to help with aerodynamics. If the front alone is raised too much then the aerodynamics are messed up causing front end lift at high speed. Daily driving this way is one thing. Driving at high speed is another. Be careful!

Thanks for the reply. I see we have similar set ups . I drove it at 110 mph the other day and it was planted..no issues. I believe that the front bumper helps to steer the air to the sides and over the car. I really raised it only two inches. I keep looking at other 997s and they all have more of a gap than I did before so there must have been something off about those springs...maybe aftermarket? My wife drives the car often as well so I rather be safe than sorry
