I will be doing both DE and AX this season with my 914-6/3.0 liter. Haven't done this for 5 years.
I have Goodyear GS-Cs on the car: 205 Z 55 on the front and 225 Z 60 on the rear. I remember that when I did drive the car with PCA DE, the rear was somewhat loose. Any recommendations for a starting point tire pressures would be appreciated. Different for DE and AX? I do have an infrared temp meter (the point and shoot meter). Would this be any help in refining pressure after a run? |

I can have some numbers for you on Tuesday. I dont typically run Goodyear GSC's...but I'm pretty good friends with Roger and Brandon Krause (GoodYear race tire distributors for NorCal 30+ years)
Normal response: 40-42 hot 32-33 cold Start the fronts off 2lb's higher than the rear. If you put the heat gun on the F+R..you will probably find that your really putting some heat in th rears. I would most certainly use your heat gun (better yet..have someone else do it for you after a hot lap) If you have an adjustable front bar.. tighten it a little on both sides. B |

Thanx.
The tires are 16" by the way. Same recommendations for DE and AX? |

AutoX doesnt put anywhere near the same heat into the tires.. so start them higher around 36lbs or so. They will only grow 3-4 pounds as the day goes on. The target will be 40.
