[4pipes]

I've tracked my Kirkham about 10 times. The very first time, a guy in front of me went inside an apex and showered me with gravel! Got a couple of small dings on the nose, but not too bad. No other damage since.

I had to add a differential cooler because it got so hot it failed. It's a major pain to remove the diff. on a Kirkham. Other than that, it was quite reliable.

I have since stopped tracking my car......just too dangerous with no structure between me and other potential impact objects.

I have a stroked Shelby FE that now develops 625 foot lbs.
