MOTORHEAD,
I have an E-M. I think it's a Series 3
It has Jag 3.8S rear axles and wishbones with four Aldan shocks. Not sure what you mean by "suspension specs" but if you can be a bit more specific I'll try to help.
My front suspension is Mustang II with a 1993 power steering rack and Aldan shocks. I believe the higher numbers are stiffer settings on the shocks. Keep in mind that with the single adjustment Aldans, the only adjustment is for rebound. If you have the double adjustables, then it's both ways.
I have a single master cylinder with power brakes so no help on balance bar; I use one master cylinder and a manual proportioning valve. My fronts are 13" Mustang Cobra brakes. The booster is from a Subaru. Works well.
Dunno if this helps,
Tom
