Yeah, I've looked into both those conversions before and spoken to Dave and Nico about them. Got some good ideas from both guys, but I think I've found an elegant middle ground. Long term, I'd love to do upper mounts similar to what Nico did, but the machining involved will probably put it out of reach for a lot of people. His design gives a lot of opportunity to modify mounting points and to use the upper mount to help lower the vehicle.
For now, I've prototyped something closer to Dave's set up, but with a few tweaks to allow reuse of the OEM upper bushings and chassis mounting bracket. Need to bang out a new drawing for rev 1.1 on some rear end parts, and develop the final piece to convert the front coilovers to the EA82 chassis.
Pretty excited about all this!
