According to my mechanic, a previous owner had a regular 996 rear driver's side subframe installed on my GT3 following an accident. The suspension member mounting points are rubber, instead of the solid GT3 mounts on the other side of my car. He hasn't inspected it closely yet to confirm if the geometry is the same or not. If it's the same, we may install solid bushings such as these -

If the geometry is different, I'll be looking for someone with a parts car who has a driver's side subframe for sale. Anyone have one or know someone who might?

Thanks.

I do not know who has one. But to confirm the geometry, the alignment report shall give you a good indication, provided both side settings (eccentric and ride height and dogbones if they are adjustable) are similar.

If you order pn 99633105590 you will likely receive a side section with two labels attached. The part number labels the new GT3 side member are as follows (see picture):
99633105501
99633105590

Please note that the first number is applicable to the C2, C4 and turbo per PET and the second number is applicable to the GT3 and GT2

I suspect the side member is the same with the exception of the solid bushings. I will try to get you some measurements of the distances between the casting boss and the thickness of the solid bushings this weekend.

Thanks guys. I just ordered a used GT3 subframe from LA Dismantler.
