Changed my oil and filter last weekend. Also new air cleaners. My throttle body was sticking a bit so I cleaned the blade and internals. Put the new diapers on the belly pans...thanks Torrie. Also put new rubber on the rears. After Rally 12, I was down past the wear bars. Got Bridgestones from simple tire.com....thanks Mongrel. Date coded late '16. Costco mounted and balanced them for $14 each. Major wear in the central portions of the rear tires. I usually run them at 30 psi on the street. May have to drop to 28 psi per Frankie's recommendation to even out wear.
