I have been racing with my partners for 50 years and always on a tight budget. No money makes it difficult to recover from adversity.

We raced what we built. The dollars spent had to produce.

Why would I risk our racing money on a trick of the week.

I know that I will take some heat for this post, but that's OK because I've handled heat my whole life...

As I remember back there was a very well known Junior Stocker guy that had written on his car "Trix are for kids" and it's still true today.
