Gents;

im in the process of collecting new/used suspension parts for my 01 turbo upgrade project this winter.

I will be replacing/upgrading rear dog bones, control arms, links , harder bushings etc & adding front bump steer kit.

I have a source that is selling 997 GT3/RS used LCA's along with solid thrust bushings & OEM outer bushings. They also have 996 GT3 LCA's (used) as well.

My question is can I use the 997 LCA's & 997 outer LCA bushings vs. 996 LCA's?

Several sources have told me the parts are interchangeable between 996 & 997?
I have already purchased dog bones & outer 997 outer LCA bushings.
Let me know your thoughts.

Thanks Rich

996 LCA

996/997 arms are interchangeable. The forged 997 arms (smooth) are 5mm shorter than the cast 996 arms. The length of the inner joints is what determines whether you want to use them front or rear. You want the short versions for a street car. The long versions will give you 3.5-5.0 degrees camber. The LCAs pictured in the 2nd and 3rd pic above are not Cup parts, they are street 997.2RS versions (rubber inner bearing and thrust bearing).

The best arms are the 997RSR versions with the rebuildable heavy duty outer monoballs. I run the "rear" RSR versions on all 4 corners. PMNA no longer sells the regular Cup LCAs, only the RSR versions now. I think they are around $1200 each if I recall.

Ok- Powderhound- thxs!


I already have these 997 RS outer bushings (short version).
So would the best street set up be to mount them to 996 GT3 LCA's or the 997 GT3RS LCA's?

Thxs Rich

You can mount them on both the 996 or 997GT3 LCAs. Keep in mind if you install the 997 versions on the rear you will not be able to fit the rear 996GT2 brake ducts on them. You will need to use the 997 ducts which will require other mods to fit.

ok- thanks powdrhound.
i also need the nut/washer mounting hardware for the outer 997 bushings to mate with the LCA's.
Do u have source?

You can order them from your local dealer. They are in PET.

If i recall correctly you should be able to install the 997 turbo rear brake ducs on those control arms.
John - can you confirm ? If that is the case - they're about $30 each IIRC

You can install the 997TT/GT3 air guides that divert air to the calipers. You can see those in the picture below. You will however need the 997 belly pan with the NACA ducts so that air can be diverted from under the car to the air guides. These are the same parts that are on your 997GT3 Enrique.

You can also install the 997.2 brake ducts seen below. Install is tricky as you will need adjustable drop links and motorsport shocks with limited droop to get them to fit properly otherwise you will have interference between the ducts, the sway bar ends, and the toe arms. They will not work with stock parts.

Correct that's what I did to my 996 use the 997 break ducs and use the 997 Center belly pan. I would recommend that as if I recall correctly it also provides better cooling to the gearbox.

I forgot to mention also if you change the center panel in the middle of a car you can install the left and right under trays under the car for much better airflow and protection underneath the car. I think I was a pioneer for this way back in the day

Which bump steer kit should I purchase?
Are they all adjustable?

Thxs in advance

powdrhound

Get the Porsche Motorsport 997Cup/RSR stuff. It's the last pic in post #9. The front tie rods look the same. Both have adjustable bump steer. Rears are about $1000, fronts about $700..

Can you provide the part numbers for these belly pans? I am very interested in getting better cooling to the transmission and the rear brakes.

Did you ever get these, if so what are they?

Thanks

Never did get a response, but I ended up installing some naca ducts on my 996TT belly pan to help get some more air up into the rear wheels. Not sure how much it helped, but I figured it couldn't hurt either.
