[Mac_5.0]

I am in the market for upper and lower rear control arms. I have read a few good things about the BBK ones, but my parts guy says he can get a better deal on the MAC ones. To me they both look almost identical in the pictures. Does anyone out there have a preference? Also, is it worth stepping up to the fully adjustable control arms? I will be doing a mixture of some light autocrossing and drag racing but mostly just driving on the street.

Thanks
