From what ive seen most companies stick 250lbs springs on 306 coilies, but depending on the rear setup this should probably be softer with a standard beam (especially DTs) and stiffer for 21mm+ bars. Ive also found that the standard coilover springs are normally quite small (7 inch), tbh, they could really do with the extra travel to stop them coilbinding!
