Griggs SLA Front Suspension
Just got an email about the newly developed SLA system from Griggs. Depending on the price and whether or not I could use it with a MM K-member it looks like this may be my front suspension for the coupe. 
Griggs Racing Announces
a New SLA Front Chassis System for the GR40 Mustang
Fully track tested
Simple bolt-on installation
Substantially increased front grip
Improved turn in
Better lap times
Reduced entry and mid-corner understeer
Improved anti-dive*
Better braking with less static camber
Improved front tire wear and temperature balance
Improved camber pattern
Stable roll center
Minimal track change under braking
Easy alignment
Accommodates wider wheels than other SLA systems
Utilizes friction free ball joints
Coil-over shock system for adjustable ride height and corner weights
Utilizes existing GR40 K Members
Available for street and race applications
Utilizes stock SN-95 spindle and hub on street applications**
Can be used on GR40 modular spindle and hub system
Brake brackets available to mount most 3.5 inch pattern calipers on 13 13.5 and 14" rotors on SN-95 spindle
May interfere with some existing radial mount brakes and therefore may require bracket modification to fit.

Huh. Looks like this is something I'm going to have to keep an eye on for a while. I really don't want a Grigg's k-member, so I'll have to wait and see if anyone tries to use their SLA setup with a different k-member.

Alan,
If it's designed around their K-member, I'd guess you'll have to use it. Moving the lower control arm pickups is going to have some pretty signifigant effects on geometry. It could take the arms out of parallel at ride height which will send your roll center and camber curve all to hell. If they mount further inboard or outboard (even slightly) you'd need to have custom length control arms made up to get the camber back within adjustable levels, but changing those arm lengths is going to screw with bump steer and roll center height.
Keep an eye on corner carvers. Once it's out in the hands of normal mortals, somebody will get some measurements and put it in suspension analyzer and then you'll be able to get an idea of what's going on.
Apparently MM has an SLA prototype as well, so holding out might be the best thing.
Mars,
I know Bartworks makes one. I think there's one other, but I can't recall who right now. I'll post it up when I think of it.

Thanks for the info Leonard. I'm pretty impressed by the price on the full setup. The whole SLA setup is barely more expensive than the standard full Griggs setup w/coilovers. Definately looking forward to see what MM has to offer down the road.
