Cool, another Z4M with an SLR kit...
After a couple seasons on the car, some feedback:
Overall, good kit. Sean is excellent to work with and is
very responsive. Steering isn't too quick, as I feared. Arms and hardware seem stout and are holding up. Camber is dialed way back (-2.5/-1.5). Not sure if it's the roll center correction or something else, but tire temps confirm that the car doesn't like a lot of camber.
Three issues with the kit.
1. Hardware loosened up on me, creating a scary shimmy at speed. I double nutted all the hardware, but I still check the torque on the nuts frequently. See pic.
2. Tie rod ends are not very good. Mine developed play after one season. I ordered higher quality Aurora rod ends ($75 ea) that seem to be holding up much better. You can see the part number in the pic.
3. The small FCAB Delrin bushings wore out after a couple seasons. They're easy to replace and Sean sells them for a very reasonable $25/pair.
