Yes, my car is lowered with Eibachs. The radius is almost identical to the one I had with the oem 19s. I recommend you go to http://www.willtheyfit.com and play around with different options. That website gives you all the comparison details between your current setup vs your planned ones.
PM me your email address and I will gladly send you some pics.

Thanks!

Yes, they are 18s. I'm running 235/40/18 on the fronts and 295/35/18 on the rears.

The seats are from a 2007 Turbo. The support is amazing compared to the standard comfort seats. The seat back is power - the sitting portion of the seat is manual. They have been in the 993 for about 4 years w/no problems. The install was not too difficult as I recall. They went on the original rails with minimal modification I had to change the electrical connector on the 997 seats in order to adapt it to the cars seat connector. There are others threads on rennlist detailing how others have managed the conversion.

sorry don't know. no thread was referenced but I'm assuming the clutch spring?

Kevin--

Look closely. It's a pic of two cars: my white 997 C4S and my brother's F430 F1. We took two identical pics, one of each car, with an iPhone, and a software allowed us to combine into one.

Can't seem to be able to load a pic here in this pm. The "Attach Image" icon takes me to a URL address and it won't allow me to upload the pic.
