Some of us are well over 100k without these issues. My Supra radiator didn't give up until 125k miles and over 15 years old. Cracks in the plastic tanks are fairly common, but very rare under...

When we talked about this in 2009, Circuit MS said they would look into a resistor set up to fool the airbag computer.

Why would you want working airbags at the track? Put in the Recaros and a hoop with a harness bar and put in a five point. Airbags kill people. Five point hitches save drivers every weekend.

I sat in the RC-F with a sunroof. I am 6' 2" with a 34" inseam. I cannot fit in the car with a helmet on even under the best circumstances. Definitely keeping the IS-F.

Your dealer's SA is an idiot. A car smelling of raw gasoline then going up in flames isn't good for the brand.

have you checked wire continuity with the cover off the ECM? If it were mine, I'd check to be sure it isn't the connector pin in the plug connecting the ECM. I've seen this before.
