Hey guys I jumped on a k brace because it was so cheap and the company claimed they were no longer in production. Now however it is rubbing my cat on it when the motor torques under acceleration. I've got 255k miles on my 02 macs and was wondering if this is a little too much engine twist. Anyone know any links to say some lower rear engine mount polyurethane inserts or a full engine/ tranny mount polyurethane insert kit for my r53? Or should I put on the bsh mount? Also when I installed my new exhaust 4/6 of my bolts holding the resonator support plate on snapped so I am no longer using that. Could that cause extra play in my exhaust as I thought that was just side to side play.
