Shelby Drop LCA Camber fix ?

Post #1 by powerband » Thu Mar 30, 2017 10:50 am

After Shelby Drop (1" down and 1/8 back), the '61's Camber is Positive with all UCA shims removed, not good alignment wise.

Adjustable LCA camber setups for popular '"65 Mustang" apps' fit 60-65 Falcon/Comets as well. Seems simple to move LCA Pivot Bolt flange outward .

OpenTracker setup is common with slots added to the LCA's frame bracket. Most pictures installed, show LCA bushing pivot bolt moved @ 1/2" outward to get some range of Caster and fine Camber adjustment with UCA shims. OpenTracker requires removing LCA's frame bracket folded flange

Considering: Setting the UCA shims to give some range In / Out (@ 3/8" ?) , then set spindle Camber close to Zero and Re-drill lower LCA flange pivot bolt holes outward as needed to keep @ zero setting. Then final camber could be set with UCA's leaving some range for caster adjustment as well. After re-drilling Grade-8 washers would be tacked in place.

Any experience with OpenTracker or other Camber fixs' or Longacre alignment gauge info appreciated.

Have you checked to see if the spring towers are still standing up straight? Many after all these years are sagging inward. Good luck :nod:

Something does seem amiss. I have 1 or 2 degrees negative camber and still a small shim or two on my Shelby'd '62.

... thanks for the continued discussion,

Shock towers and most of front end are solid and don't presume frame too far out of spec. Parts and specs may be strange with the early 61 Comet.

I moved the LCA pivot bolts out @ 3/8 inch , now UCA shims are in reasonable range of negative camber - positive caster.

With a bubble ( ) - / \ gauge, I'm zero'ing in on the alignment, getting close to @ -.25-.50 camber and @ 3 degrees caster. My Toe In measurement setup needs more simplicity and accuracy . Planning on adding adjustable caster strut rods for more options and fun ...

Very drivable and a different body response in curves. Bump steer is minimal, more modern feel - non-PS (maybe slightly heavier?) .

I made a Ford spec front UCA support years ago and finally used today today @ ten UCA adjustments.

:beer: nice detailing work on the front end parts. :thumbup:

I just got around to finishing my front suspensions rebuild on my 62 and after the drop.im having the same issue I'm about 2.5 degrees positive with no shims in place, you said you just redrilled the hole 3/8 outward? Or did you elongate the hole 3/8 inch outward and just torque the bolt I'm looking to try and fix it without having to resort to the open tracker setup since the parts are already in the car

I re-drilled to just clear original holes and cam bolt is only for reinforcement, it won't adjust.

The dilemma of the '61 continued with camber and steering geometry problems with LCA's moved out so: LCA pivot bolts were returned the to OEM location and also UCA location Shelby drop was returned to stock and the pricey 'HD UCA's' replaced with standard Dorman re-pops. This gave me the more modern range of Camber adjustment at @ negative 1/2 degree/side with @3/8-1/2" UCA shims. I'm not convinced the root of problem wasn't the new 'Heavy Duty' UCA re-pop with a slightly different UCA shaft diameter . I probably should move the Dorman UCA's to Shelby drop position to verify .

Unexpected side effect of initial '61 Shelby drop was exaggerated lowering of front end @ 2" compared to final OEM position with same coil springs -?. Early car 60-61? vendors specify different coils then typical 63 -65 and up.
