Nice. I have the camaro mod on mine as well and yes the the pipes were quite tight originally. I took some 220 grit sanding paper and gave them a good sanding and polished them up with some silicon spray lube. Glides pretty nice now. I am still working on getting my ramps and everything setup so it has all been hand based movement.
I think I will have to bite the bullet and upgrade to this new version as my build is 5′ x 5′ and the most rigidity possible will be necessary. Thanks for your input.
