Update I put my new tires without tubes and went to the local track which did not had a very good preparation (so I thought). Well just of the trailer it went it's ever best 9.16 at 145.5 and 60ft's 1.27. We are sittiing at 450 elevation and temperature was 60F. Past best ever was at a very good track in Monterrey Mexico elevation was 1400 and temperature was 82. Well going back to this weekend update I went to race the final and car actually got faster and was dialing 9.12 in semifinal and final and going 9.13 letting go just a bit. I think the car would have gone the 9.12 or even lower (9.11-9.10). Oh the 60ft's went to 1.25 twice. In the final it was very cold temperature was at 49F. I did not do anything to the car as far as moving ladder bars. Like I said before they are in the top hole and I measured them race ready they were 5 degrees down so I did not want to move anything. From previous best only things I changed was a front strut that was shut down (hard) it was rebuilt. The car use to be very stiff because of that. I placed the stiffnes in the strut in the middle more softer and soften the rear schocks 3 clicks and rear spring were replaced form 175 to 130. I guess it was the tires after all what do you guys think..

Sounds like it working good now Keep tuning and testing
