Common weight reduction techniques include fiberglass body panels, stripped interiors, and Lexan windows (sometimes color tinted).

[6] After the company revived, the 1937-42 coupés, sedans, and pickups were again popular with hot rodders and gasser teams, and again, comparatively low production leaves unexplained why they gained so much attention.

[4] Ollie Olsen's 1940 coupé Wil-A-Meaner (driven by Bob "Rapid" Dwyer[citation needed]) won the 1961 Nationals' A/G title.

It was very common to fit a Roots supercharger modified from original use on General Motors two-cycle diesel truck engines and mechanical fuel injection, manufactured by Algon, Hilborn, or Crower.

With form being dictated by function, their appearance is often very top heavy and ungainly, largely due to front ends being raised higher than stock, to assist in the weight transfer during rapid acceleration (racing).
