A friend of mine let me have a mint condition RD stress bar from his 97 M3/2 (bought an M-coupe), and I figured what the heck, I might as well put it on. Do any of you guys have installation tips you can recommend? I mean, do I just unscrew the strut tower nuts, drop it in and re-tighten the bolts? Any special torque settings for those nuts? Will this screw up the front strut alignment if I loosen all the bolts? Thanks.
