Remember, this is a street rod, not a drag car. There is a difference in application between a 4 bar and a 4 link rear suspension. Mine is a triangulated 4 bar - best suited for street rods / "g" machines. 4 links are best suited for drag /race cars ( much more instant center adjust ability for track conditions).


Mine will be street so you suggest a 4 bar over a 4 link?
Yes, especially if you have any kind of room constraint issues, which street rods often have.
