We currently don't have a 4 wheel scale system to do corner weighting but I could look into it if the demand was strong enough. You would need adjustable height suspension to pull this off just to start, which I'm sure you know.
I have a few suspension guys available that I would bring in depending on the job. Most of what we would do involves suspension tuning based on already hard known facts about the car. There are some excellent base lines to follow in terms of tuning an STI suspension for example with after market parts. Fine tuning would be done on the road or track and may involve some special tools realted to measuring suspension travel, roll, etc.
Basically it would completly depend on the job and how serious you want to get. I have connections with very good suspension people both local and in the lower 48.
