I have a 2015 Spyder RT Limited. Recently I put an air gauge on the suspension system by attaching it to the schraeder valve under the seat (screwed on type gauge). I monitored the pressures over a week period and here are the PSI's I got > Sunday 50, Monday 49, Tuesday 47, Wednesday 46, Thursday 44, Friday 43, Saturday 41, Sunday 40. So as you can see, the system lost 10 psi over a week period, in a heated garage for the whole period, never sat on, and gauge never disturbed/removed from Schraeder valve). Have any of you ever monitored and noticed the drop in pressure when your Spyder is parked? Is this normal?
