Any info on these parts? Do they work?


These are the trick 2003 1/2 raised wheel carrier/uprights that were part of $11,000 plus upgrade Improved roll centers and CAN be used on street cars as well. VERY TRICK PART. They have about 15 to 20 hours of time on them.




"Motorsport Raised supports. These come with factory solid mounts and are raised an additional 15 mm. Part number 996.331.055.9D" raise your roll center on Lowered cars to get the geometry back to where is should be."

Those don't look like GT3 RS parts to me.

The RS parts have 2 bolts to retain the front strut, these parts have only 1 Also the wheel bearing is retained with 6 bolts on an RS, not 4 like these.

Also the RS uprights are hollow and so appear very different otherwise as well.

Cupcar

996.331.055.9D is not a part number 996.331.055.90 is the side member for a normal GT3

I think these are normal GT3 parts so these would upgrade a normal 996 to GT3 specification and achieve the results claimed for that car but not a GT3.

G,

Those parts are not from the 996 GT3 RS. Here is the picture I took from my RS uprights earlier this year.

These same uprights are used on the 997 GT3 as long as you order steel brakes. If you order PCCB, you get different uprights, and I don't know why.

Thanks to these uprights, the Mk3 feels easier to drive (read feedback from 997 GT3 drivers). Same goes to a 996 with this upgrade. These are hollow uprights made on Magnesium.

Yep NJ-Gt those are the RS ones. The ones Z06 you have pictured are the standard GT3 uprights (also the same as the Cupcars). No improvement for someone that already has a GT3.

Thanks Guys for the info, I found them on ebay, here is the link, just scroll down.

R, Are you selling any of your suspension parts?

viperbob

Yes, but what did the guy upgrade for $11K??? A standard 996?

Z06

this is a reply from the seller,

The were used on a Grand AM GT car... There was some misunderstanding whether they were legal or not and when they learned the were not legal for sure the owner had them removed.. That's all the history I know. I have one rear and sold the other to a team that crashed and needed a spare.

NJ-GT

No. That's why I requested feedback for my car market value with a stock suspension. I might need all these parts for a wider car.

The 996C2 and 996GT3 have the same uprights?

NJ-GT

No. 996 GT3 and 996C2 use different uprights.

The 996 GT2/GT3 have the same uprights. The Boxster/Carrera 2, same uprights. The 996TT unique uprights. The 996C4/C4S unique uprights. There are uprights differences on pre-2002 Carreras and pre-2000 Boxsters compared to the newer 996/986.

Here is his responce,

Sorry but, you received some incorrect information from someone that doesn't understand exactly what these parts are or actually doesn't know what they are talking about. The 996 RS European STREET car version and the 996 RSR Motorsport version as well as the 997 CUP all have 6 bolts on the bearing plate and two bolts on the strut pinch bolts as well as many other changes. If fact the part he is talking about is a completely different casting. What I've listed here is the 2003 model GT3 RS upgrade. The casting number on the part is 996.341.657.9D and 996.341.658.9D and these are actually more expensive then the others he is refering to. Please don't bid if you are unsure if these will work in your application but, rest asure, these are the real thing. You have to be very careful who you talk to because there are many versions of this stuff and it's easy to mix them up. Hope that helps clearify the question. Thanks

Are the differences to locate the control-arm mounting points lower or to simply accomodate the 6-piston caliper?

karlooz

the mounting control points are the same gt3<=>996c2 and the uprights are to accommodate the larger rotor diameter and 6 piston calipers. the gt3 and 996 share the same PET part number for the rear upper control links, track (radius) arms, control arms and the PET shows the 2 piece gt3 track arms are optional/retrofit for both front and rear control arms on the 996 (which i am currently using). gt3 struts can also be swapped onto the 996.

the front subframe appear to share the same part number however the rear subframe, to which these control arms attach, have a different part number. this can suggest rear revised geometry.

Cupcar

GT3 front wheel bearing is 10 mm larger diameter than 996 and track rod coupling changed as well- not sure what this track rod coupling change is, I am just quoting the factory book. Book says: "The track rod coupling has been adapted to neutralise the effect of the overall axle geometry (kinematics) resulting from the reduced vehicle height (30 mm lower)" The track rod is a different part number on GT3

Rear wheel carriers same for later 996 and GT3

The GT3 rear side sections have no rubber(solid) mounts and are raised 7 mm compared to 996
