Wishbone suspension bolt on kit

[GS guy]

Hey Jason,
Sounds like your IFS is getting a pretty heavy makeover - before it even hits the road! All in the details isn't it!?
I decided to build my IFS around the Mustang II based components. This is a custom modification to a tube frame chassis fiberglass buggy, but might still be of interest (switching from balljoint front end to IFS).
Couple of interesting aspects - the MII spindles weight less than 1lb more than CB lowered drum brake spindles, yet take much larger bearings (~0.200" larger in diameter) than the VW. I'm using a bolt-on disc brake kit - solid rotor/aluminum hub with 11.75" rotor diameter & 4-piston Wilwood forged DL calipers.
Compared to the BJ set-up - I'm loosing 3lb per side in unsprung weight despite the extra beef of the MII hardware, and despite my previous BJ setup using custom adapters and Wilwood 4-piston calipers (already much lighter than std. disc brake spindles and VW iron calipers!). A bonus is I get a lot less scrub radius and rack & pinion steering. On paper the geometry looks pretty good - my next step is to assemble the hardware and take some as-built dimensions and verify locations of the inner pick-up points. I'm designing an adjustable upper A-Arm pick-up location for tweaking caster and swing-arm length - if necessary after it's built.
