I have the MMR rear spherical trailing arm bearings in my car and still use the factory toe eccentric and factory toe links.
Everything is mounted with solid bushings - solid heim subframe link, UHMW diff and subframe bushings, Solid front diff mount, PBM camber links, DTSS eliminator and PBM solid rear upper hub bushings. Suspension is silent, and it never has any wheel hop.
I was wanting to go with solid stuff but the makers of a lot of these things really seem to have dried up for the FC. There was only one ebay seller with solid subframe bushings and was quoting a delivery date of mid-april. PBM has aluminum diff and subframe mounts but they are all designed in some way to tweak the location of items for cars that are substantially lowered, which my car isn't (at least in the rear).
