Sounds like your car is way down on power looking at that trap speed. That is really slow. My 84 Celica's trap speed was 78, the Supra traps at 85. I don't know what your 60' time was but you may be able to get a better E.T. by lowering your launch speed. I usually go around 3000, the track here dosent hook up very well with street tires, I can actually get a better launch on the street than I can get at the track. Anyway your 60' time should be around a 2.4 or lower, every .1 you take off that will equal about .3 off your E.T. But its not really going to change your trap speed, that is mostly affected by horsepower.

Just buy the copper ones $1.59 each. Car guys like us change em every once in a while anyway, platinum is for mom's n minivans, when the engine never sees the light of day.
