You're welcome.

I don't think you should pull ideas from my design if you're building a suspension for a conventional set-up. Mine is optimized for a high-travel/low-roll setup and would not be optimum for a low-travel/high-roll set-up. It's not that it can't be run that way, but the geometry is not correct for a low travel/high roll set-up. For example, in a high travel set-up like mine, I have the geometry designed to be optimum for 4.5" of dive at the crossmember and a roll angle of 0.8°. Everything is different for low travel.

You will need different:
A. Anti-dive percentage
B. Roll Center location (static & dynamic)
C. Camber gain
D. Caster Gain
E. Bump Steer

If you build yours like mine & travel the front end 1-1/4" and roll it 3.0° ... the camber gain is too small, the caster gain is too small, the roll center is not optimum, etc. I suggest looking at examples in road race suspension design books printed before 2005.

Best wishes & don't hesitate to share or ask for help. Lots of good guys on this site.
