3.0 slowing down!?

I raced yet again!  Again in 13.5 with the 3.0. I think my tires are wearing out as tonight my car felt too edgy. Or I was having an off night. My fast lap each round slowed from 18.6, to 18.8, to 19.0!  Between round 1 and 2 the track dried out and I changed the ride height to 23mm and the front camber to -1. I may need to also change the rear roll center by taking the 1mm spacer I put under the outer ball stud to raise the roll center and stiffen the rear. Then in the main I tried my new electrons, but the track had a bunch of wet spots from the misting nozzles dripping. 

I also need to clean up the buggy some as I've been constantly racing it. 

This was also the 1st time I haven't placed in the top 3 with my 3.0 :(
