Yes, it would seem to be part of the spec line, and therefore, you can use its parts.
As far as the subframe mount reinforcements, as we discussed earlier in the thread, in my opinion you need to have some sort of proof that the M-Technic came with them. I haven't seen anyone produce that sort of documentation yet.
Thanks.. I wasn't jumping on the reinforcement bandwagon, just saw an M-Technic for sale at almost a reasonable price, and wondered if that was on the same spec line with the other stuff... just kinda looking until the right car comes along, then may pick one up to play with. Until then, I've got my ITA car I've been running for 17 years to keep rolling along with
