Commented On: HKS now offering add-on speed delimiter for Lexus IS F
Motor Authority
I was surpised by your comments about delimiting the IS F:
"A simple box wires into the car's ECU and overrides the speed limiter, letting the car go as fast as it can, restricted only by power, aerodynamic drag, gearing and the intestinal fortitude of the driver"
This leaves out a very imortant safety factor: Tire speed capacity. I'm not sure what the rating is for the IS F, but that is definitely worth investigating before a top speed run in a newly unrestricted car. I'm sure you'll agree it would not be good to have a tire fail at, say, 180 mph...
Cheers!
