Suspension mods started

and simple progressive suspensions are not that much flexible with adjustment

Actually, the springs with the Traxxion Dynamics kit aren't progressive, but as I understand it, a straight rate spring, ie, not wrapped to act as a progressive spring. If you question my assessment of the Traxxion kit, maybe someone from their company can chime in and describe the kit, vs me paraphrasing what I think I heard. I'll ask the next time I talk with them.
