What other reasons are you referring to?From what I recall, the mounting spot for the shocks on the MMI setup was so someone could go with their coil over set up without requiring a change to the lower control arm.How does where a shock mounts effect instant center?I think the coilover mounted to the LCA is a superior setup. It puts the instant center at a lower angle. It is similar to some modern suspensions.
From talking to both Mike and Shaun, I believe the geometry of both setups is very similar.
I suspect the results might be similar too.
I’ll be going with MMI within the next year for my car due to this reason, as well as other reasons.
