I ran telemetry on the SC2018X mod at Dover Speedway using the default setup with bump stop/packers set to .812 both sides and 3 inch ride height. The car ran lower to the ground with the 3.5 inch ride height setup by about .20 of an inch. I ran the same test again with a 4 inch ride and the RF ran about .25 inch lower than base line but the LF ran .40 lower than baseline. However the handling got significantly tighter and lap times slowed down everytime the ride heights were raised. I re-adjusted cambers and adjusted wedge to try and balance the car but higher ride heights always ran slower. 3.5 inch ride heights were .2 of a second slower and 4 inch ride heights was a half a second slower at Dover Speedway - which is significant on an oval. We will look into this further and correct the problem. However the performance and handling are reacting correctly. Thank you for your feedback and observation on this. On your latest post, yes front and rear have different reference points for contact with the ground. For example, a front ride height of 3 inches only has 1.1 inches of usable travel since contact is made to the splitter at 1.9 inches of Ride Height. Ride heights on stock cars does not mean Ride Height 0 = contact with the road. In stock cars ride heights are taken at the frame rails and they do not touch the road surface before other hard parts.
