For clearance on mine, about 1/2 of the intermediate pipes was re-made from oval tubing to add clearance.

Note that I don't have the BMR setup, but I don't think it will offer a lot more clearance in the tunnel. I also have a Watt's Link which added to the complexity. You will have to deal with some of that with any coilover setup as compared to the original leafs though...

This said, I like my Torque Arm setup. It just adds to the complexity of exhaust routing and ever having to remove the driveshaft...

Yeah I hear you. The main reason I chose the Torque arm setup is because all the other 3 and 4 link setups require significant fabrication and modification to the rear frame rails / trunk pan. The torque arm setup supposedly provides awesome handling compared to leaf springs but does not require custom fabrication to install.

What setup did you uses and what rear end?
