Do you need a load range E? I would expect if you need a load range E you have upgraded your springs to heavy load capacity and doing some heavy loads.. But based in your suspension thread you are just doing the super common Bilstein 5100's.

I can appreciate your thinking that you are doing something so different that these items have not been discussed. But both threads ended with the super common options...

With that in mind I will vote for the ever popular Cooper AT3. No reason for us to reinvent the wheel.

Don't take my post the wrong way. I posted a thread yesterday that I know will harbor mixed results/opinions.
