I've been using Blackstone for years off and on. Just did another report on the E46M3 and the X5 when I did the inspection II. Both were excellent. Gotta watch for wear metals on the S54 in the E46M3. Rod bearings are the usual culprit. X5 was for curiosity sake.

I like the look of those wheels but I'd never get a wheel that required a hub centric spacer. BTDT and it is a PITA when that spacer gets stuck and you try to put on your spare. Have tools in the boot to ensure you can pry that corrosion welded bastage off...
