Zonker Mk III-T D Sports Racer

Zonker Mk III-T is the third Sports Racer to bear the Zonker name. It was intended to represent a serious attempt to optimize the D Sports Racer within the constraints of a limited budget and somewhat limited equipment, and within the perceived constraints of the SCCA GCR, as follows:

Purpose-built, single seat Sports Racing vehicle

Minimum weight 900 lbs with driver

Flat-bottom design, utilizing external downforce, but no ground effects

Engine limited to 1000cc normally aspirated, or 620cc forced induction

As it developed over several years, several of these elements have evolved, such that currently (2008), extensive ground effects are now used in current cars, forced induction displacement limit has been increased to 680cc; these changes have not been incorporated into Mk III-T.

A brief history of the Zonker designation will be offered, including an overview of the technology involved in each, followed on succeeding pages by considerable detail on the conception and execution of the various elements incorporated into the Mk III-T, the final member of the series.

Since the primary purpose of this site is to provide information that a prospective owner of the Mk III-T might wish to have, and since I am unlikely to cover all details one may wish to know, please feel free to contact me with any questions. I have many, many photographs of the process of construction; I can probably provide a close-up look at an area of particular interest.
