Marty, thanks for reporting on this. However I'm having the same feelings as Tom on this one. I'd like to see a more precisely constructed lower arm that allows more bump clearance at least for the As, but now that we can purchase good quality t bars, shocks, steering boxes, strut rod assemblies upper arms and sway bars, what are we trying to improve? As far as rigity is concerned, unless QA1 is willing to put the cars on a surface plate it all seems to be a guess. Greater oil pan clearance seems to be the only potential benefit.
