997 with -20mm

[thelion]

I just had the -20mm Sport Chassis installed today at Suncoast Porsche for my 2006 997, wow, what a difference. I'm told I'm one of the first ones in North America to have it. They've assembled a kit with the springs, shocks, rear mounts, anti-sway bars, and other associated hardware. My bars didn't come in yet, they're being delivered from Germany.

The ride is firmer but not in the least bit objectionable. It transitions better and the car doesn't shift around while you are driving quickly. You do notice bumps, cracks in the pavement, and paint lines more with the suspension but it doesn't feel as stiff as a 996 GT3.

When you park it next to a 997 with standard suspension or a 997S with PASM they look like SUVs in comparison, especially in the rear with all that air above the tires. The -20mm lowers the car down to where it should be. We measured with a tape measure and it dropped the car down 1/2" in the front and 3/4" in the rear.

If you have a steep driveway this suspension isn't for you. I used to drive off the side apron of Suncoast Porshce with no problem but now the under-fender lip spoiler thing scrapes. I'm crossing my fingers tomorrow that I can still get it on the trailer fine for towing.

I'm driving it at Sebring this weekend both Saturday and Sunday. I'll let you know my impressions after I get back.

Wow the car drives great on a track. I spent the whole weekend at Sebring and passed our region's instructor's school. I'm getting nationally certified as well. The -20mm is the way to go if you want to emphasize handling and you're willing to give up some ride compliance over bumps. The other thing is you're going to scrape the under-nose spoiler lip thing.

Very cool indeed, do post your experience over on rennlist as well. Are you gonna do the LSD as well, might be more hassle than it's worth.

was under the impression '-20mm sports suspension' drops both front & back 20mm?

also wondering if you had the LSD installed / did Suncoast disable ABD?

How much--and can it be ordered from factory on new car?

You can get the suspension in kit form from Suncoast Porsche in Sarasota, FL.

<P>

It's $1749. They used my car for that photo and after driving it at Sebring two track days and two autocrosses the car sits a little bit lower. They took the photo the same day it was installed and aligned.

<P>

Porsche won't install the suspension for cars bound for North America because of the bumper ride height restrictions from what I understand.

any idea if PSM needs re-programming (for non-PASM cars) as result of the suspension upgrade?

The -20mm is how the 997S should handle, the steering is sharper and more direct, the suspension is firmer and more stable, the car is planted at +150mph speeds, etc... and too bad you guys only get the spring/shock/swaybars of the Sport Chasis cause the rear LSD really helps in slow corners and its more fun if you want to play with the rear as well.

hi,

in addition to the springs sway bars and shock absorbers, have you also installed the LSD? or is it possible. i think that is a key issue which will make a great difference in certain conditions.

I believe you have to change out your whole transmission because the part number is actually the trans with or without the LSD. I remember a while ago you could send something in and get a core trade-in, I hope that's still true because the trans with the LSD built-in is expensive. I'll let you know next week sometime, I'm going to investigate further.

[Edgy01]

The exclusion of this mod from the NA market is not a ride height issue at all. It is more of a function of the American road conditions and American driver experience factor.

Sadly. Porsche AG won't officially allow it (when you order the car for North America).

Bumper heights have not been a factor with DOT in several years.

Does anyone know if the -20mm euro springs would work on PASM cars. If so what are the part numbers for these euro springs? I have these H&R's for PASM, but it is way too low for the factory aerokit. Thanks.

I own a 3.6 997 and am looking with my dealer they are telling me they dont have the sport chasis, is wierd they said it is not available. Are the ones you ve installed Porsche Sports Suspension??

You may want to consider a set of H&R lowering springs. I had it done upon delivery and i makes a huge difference. Basically the car drives much like if you have the PASM engaged all the time. Definately feel the cracks and everything else. Not the cushy 4x4 ride and look of the stock. When you put it in PASM mode it is on rails. I will try to attach some before and after pics. Total cost was not much. I don't remember how much the springs were, but my dealer did the swap including re-allignment for $835.00.

Yes, Suncoast Porsche has the kit with 100% factory parts. They also installed it for me.

[shtintl]

I have 2006 C2S

guards red, blk leather red seatbelts, PSE, rear spoiler techart, 20in rims, HR springs, RUF shifter and paddles. the look with the springs is killer, i cant look at a stock porsche anymore and not thnk that the gap is huge. i agree with the post above about the handling, my near term pregnant wife almost had a cardiac arrest when i took her in it with the sport turned on. the exhaust is def worth the money.

this car is amazing, the only problem is u run out of road very quickly.

hope everyone loves theirs as much as i do. steve

I am planning do it the same thing. I have a base 997 (non s) with 18 inch wheels.

is your car a base 997 non s, and does it have 18 inch wheels with the 20 mm suspension. I noticed on the porsche website in europe when you opt for 20 mm sport suspension it forces you opt out the 18 inch for 19 inches, so I am wondering if you did the same.

thanks

not sure if it helps, but i too have a 997 (non-S) and had the Techart (eibach) springs installed. it lowered the car 3/4"+ all around and i did install 19" Porsche Carrera Classic wheels to help round things out a bit. i am pleased with the setup but it does require a level of attention when approaching steeper driveways and the like.
