Farmington Pro Solo

   Being thrifty (cheap) means that my old autox tires now serve daily driver duties; I hope it doesn't rain much on my trip to the SCCA Farmington Pro Solo. A San Diego local SSP competitior will be transporting my newish Toyo tires.  At over 5000ft elevation, the McGee Park event site has a gradually sloped large rectangular asphalt lot suitable for two decent sized mirrored courses. 






  









   844 miles away, I will travel all day Thursday to get there and show up refreshed for practice starts and the welcome party on Friday afternoon.  STR currently has 14 entries listed and is the largest non bump class. No boosted cars are eligible for the class so the altitude should wreak havoc equally on everybody's powerplant.  Not sure how the clutch is going to like it though.

   Not much room in the miata.  With the pedals removed, the folding bike still barely fits. 
















   Thrifty also means that I am not planning to develop the car any further at this time, and will just keep up maintenance and may possibly even re-install the air conditioning.  And bolting on the quieter Borla muffler and mounting the stock driver seat between events will bring much welcome comfort.

   The video above shows my first run of the weekend on the left side course.  I was more agressive and able to hold a tighter line in the crossover during the later runs and aside from some cone trouble thought I drove really well, but K-Mo killed the class in the Bjorn MX5.  Weather was sunny and hot.  As expected, the nearly full tread Toyos felt a little squishy and delayed in the slalom, but not bad enough to give up eight tenths per side.  Even the well-developed lightweight Toyota MR-S on sticker Hankooks could not keep pace with the bigger cars.  Launching at altitude required a clutch dump at 4500 rpm giving just enough wheelspin to keep the clutch happy and resulting in 2.4-2.5 60ft times.  Shifting to second is where I most noticed the lack of power due to the elevation. 



  












   For Saturday afternoon I raised the rear ride height 1/8" to help rotation.  Tire pressures set at 28F, 27R.
