Hi there has anyone else tried these out since this post? Did you consider tapered? What would make a B4/B4.1 owner choose tapered or flat? Tapered for rougher tracks/smooth for flater tracks?

Someone even suggested that taper could point down giving quicker rebound allowing a lower spring rate. Benefits??

Has anyone found that there lap times inproved as they went from a B4 to B4.1 either converted or just a new kit. Is the B4.1 faster all personal set ups considered. I do understand that the +8 chassis can help with this.

Please excuse the learner Q's. Thanks for any thoughts.
