Sorry to say for me there was no difference. Didn't even really notice a difference cruising 55-70. I'm up in altitude and Bob may have tuned a bit Rich. I have a back wind Restrictor too. I think I'm going to break down and get a medium length spoiler from SlingMods for my Fathers Day to me from me gift! Anyone know if there is a discount code for this weekend?
Check here - Ebay is 20% off until 8 today | Polaris Slingshot Forum Don't know if SlingMods has it listed there, but maybe...
My MISTAKE - Code expired back in MARCH! Fudge, I was about to use it myself!
