Concrete

   So with the new piggyback installed I want to thrash the car to make sure all the connections are solid and there are no driveability issues before I schedule a dyno tuning appointment with Church. There is a local autox at Qualcomm on Sunday so I head down there with the car still bug splattered and stickered up from the Lincoln journey.

   Last weekend at Spring Nationals the Toyos felt great on Lincoln Air Park's concrete and the car's balance was near perfect.  I mentioned to my co-driver in Lincoln that I felt the tires were possibly heat cycled out because they were not putting power down as well as I expected and noticed a little push on corner exit. We both agreed to disagree, loosened up the car a tad and just drove with ultimately good results.

  











   What a difference a week makes.  Today I used the same Toyo tires at Qualcomm Stadium here in San Diego and the car was miserable.  The asphalt surface at the Q is low grip and the on-off camber changes are challenging, but I have never noticed such a dramatic swing in performance between two events.  I guess my Toyos were done after all.  

What is all this about and why am I rambling on?  I don't know.

   Due to the unique surface and low grip, new and/or full tread tires always seem to work best at the Q relative to other sites.  The site at El Toro has a high grip surface similar to LAP and I really need to focus more setup time at this venue in preparation for Nationals. 
 
   So now what?  Do I chance using the old Toyos again at the upcoming SCCA Southern Pacific Super Regional autox event at El Toro on June 15-17?  Or use the 225 Hankooks?  Bust out the new Toyos or save then for Nationals?

The piggyback survived just fine although the stock rev limiter at 7200 is annoying.
