I'd be interested in lower control arms that had raised ball joints to allow you to lower the car without effecting the roll center (you'd be able to lower the car more without the control arms pointing up). These are common on older 911s but no one is making them for newer 911s...yet.

Porsche offers tapered studs of varying lengths to accomplish this in their racing parts catalog though I can’t seem to find where I had the document saved.

Once I get everything buttoned up I will play around with making some tapered bushings of different neck lengths and longer bolts to lower the upright attachment point to improve roll center geometry.

Keep us posted I would be interested in a set if they can improve the roll center.

Finished some thrust arm center links and am finalizing rear monoball mounts with an adapter plate to facilitate mounting the Ohlins coilovers.

Fantastic - Haven't had a chance to comment and glad the thread moved up the stack.

Roll center, bump steer adjustments, excellent - Too bad it isn't SPB legal.

Spec 944 allows spherical bearings, why not SPB. Far cheaper and easier than replacing the Porsche stock rubber ones.
