control freak ifs

[Nothingface5384]

im failing to understand..
it uses Wilwood Pro MII spindles, but vendor says its not a mustang II kit...

Yes the control arms are fabricated, but everything has to be Based off the spindle, so that makes it a MII kit!

Ummmmm -- No.....

DSE and Art Morrison use C5/6 based suspension uprights, but that does not make their suspension the same as C5/6. The spindle (upright) is one component. You could take (and people have taken) a MII bases spindle and make a suspension that is geometrically completely different than stock MII, with completely different performance characteristics.

I have no idea what they've done with there design, but to state that the spindle (upright) defines the suspension is incorrect.

Im going to respectfully disagree..
based off of m2 or c6.
maybe im too logical. But..
based Off of means An improvement over the core designyielding better geometry to fit said platform.
of course AME doesnt use c6 geometry...as stock geometry is for a corvette and. not a chevelle, camaro or w.e...but its still a c6 suspension altered to fit and have correct geometry improvements for the car platform its being retro fitted for..

I doubt any m2 "based" package actually fixed the lateral migration and low front RC issues

The major difference between the AFX spindles for GM cars and the Wilwood Pro spindles.
AFX spindles were based off c6 bit ddsigned/altered for older platforms whereas the pro m2 spindle wss just an improved upright for a pinto/m2.. no other model...they just happen to get used in hotrod or m2 reto kits like fatman fab or rod and custom motorsports. ..or this example freakride suspension..

Okay, lets try a different tack, what part of the rc position and lateral migration (is that RC migration? Side Scrub? Which migration directly?) do you feel is limited by the spindle design? Rather then simply stating that it can't be because feelings, actually point out the faults in the spindle design so that others can learn your thoughts.

IMHO you are not looking at enough of the parts. The 'Pro' M2 spindle is only a spindle. I has I has four key components in it's geometry. (you should view a spindle with the ball joints and tie rod ends installed, and look at the pivit points) So, Upper ball joint pivit point, lower ball joint pivit point, TRE pivit point, and the hub face (spindle pin). These points form the KPI (or SAI), scrub radius, and steering angles. I would say that the use of a certian spindle itself, like C5 or M2, does not make a clone of the OE design. Now, if you add in the same steering component to the design (Pro spindle and M2 or T-Bird R&P) then you have a different story. The rack forces a certain Tie rod length, within reason even with a custom steering arm, and that forces a certain range of A-arm length and location. The geometry can be cleaned up a bit, but it would be still based close to the OE design - IMHO.
1. Aftermarket IFS with C5 spindle and M2 rack = not so much based on M2 design.
2. Aftermarket IFS with M2 based spindle and M2 based R&P is pretty much M2 based IFS.
