So I personally drive a less than street legal S13, but my wife drives a stock Q50. I was thinking of letting Tanabe do their "Winter R&D" stuff on the Q since I work right down the street and can pick it up when they're done.

Has anybody done this? If you have, what do they do? I'm assuming they put your car back together...

I've never done it but that's the normal method of these places doing R&D. Tell them the AWD Q community needs some moderate lowering springs
