That's what I figure, I still think it's a good number for here, I drove it to Amarillo and back last weekend to visit family, on a long stretch of a lonely New Mexico road I laid into it, about 85-90 I started hearing a rotational vibration, at about 100 the vibration stopped and I started to smell rubber burning so I let off, the car has been squirly on bumpy roads since I bought it, I just thought it was that way from being light. I got home and noticed I had no tread left on the front tires, I took it in for an alignment verification and 2 new tires, the front drivers was 3 degrees toe in, passenger front was 2 degrees toe in, drivers rear was off by a degree, he didn't state which way, so I had the alignment done and tires and it feels like I am driving a completely different car now. I am wondering if the alignment being off was putting a drag on the car and slowing me down, I am going to take it to the track tomorrow night and see how it does, but with the temp going up so is the DA so it will be hard to tell.
