With Victor's first MESAC race, he was loaned a Greenwood Corvette anglewinder car from Dave Sloan to race.  The Greenwood Corvette was the largest car in the field.  Victor remembers the car was hard to drive on the tight road course (MESAC could configure the track to various layouts).  The front end would tilt out in the tight turns.  Victor told me he preferred inline chassis cars and smaller cars for the tight track conditions.  Lotus Europas, Porsche RSRs, and BMW 320s and Camaros were popular choices for the MESAC races.  Rick is building a Porsche RSR for this class.
 
This car embodies some of measures Victor would have taken to tame the big Greenwood Corvette.  It has an inline chassis versus an anglewinder one.  This car also has independent front suspension and steering to help prevent tilting.  The car is powered with a C-can Group 20 motor that was the MESAC motor of choice back then.  The C-can motor has white-dot magnets and a Steube group 20 armature.  The crown gear is a Weldun.  Tire diameters, as dictated by the rules, are 7/8" front and rear.  Wheels are Cox set screw ones. 
 
The car is very easy to drive with neutral handling.  No tilting in the turns.  The motor supplies good drivable power.

Did the rules require such wide front tires?


You can't always get what you want...

Most cars used these fronts.  They are about 1/2" wide.  These are original MESAC fronts.  The are made with cut down Cox rear tires.  We also noticed some cars with sponge rubber fronts.  Victor says the front tires were normally coated with enamel paint.

Here is an original MESAC car.  The tread was also painted on.
