Does watts link length matter?

[darkostoj]

Hey guys!

Building a new rear 9" axle for the Rolls Royce and stumbling around on building the rear 3 link.

Axle WMS is roughly 62"
Lower control arms are 42" apart
upper 3 link is 6" off centerline
Using a 5" watts link bellcrank mounted to the chassis.

I have the option of running the watts link mounts inboard the coilovers or outboard the coilovers.

Inboard gets me around a 28" watts link length (2 - 14" arms)
Outboard gets me around a 52" watts link length (2 - 26" arms)

Inboard is much neater and easier, where outboard won't turn out as nice and have a few clearance issues.

Any ideas or recommendations?
