May 30, 1964 - The 48th running of the "Greatest Spectacle in Racing" - The Indianapolis 500. This page begins in October 1963 and offers
a chronological accounting of the 1964 Indy 500 from the Thompson Team's perspective.
Mickey Thompson hires sports car star Dave MacDonald to run one of his radical new low-slung racers in the '64 Indy 500.

Photos below are from the November 1963 tire test session at the Speedway. Testing scheduled for five days beginning on the 26th with
Dave MacDonald, Masten Gregory and Duane Carter on hand. These crucial first laps with the larger 15 tires would either ease or confirm
the teams fears that the cars taller stance would have a negative effect on handling. Below MacDonald sits in the 82 car with compliant 15"
rubber while Thompson checks the scales. [Dave Friedman/The Henry Ford]

remained but both drivers felt an improvement and at this point at least would stay committed to the team.

May 1, 1964. The Brickyard officially opens for practice.
All eyes on Mickey Thompson's exotic full-fendered superskate as the team begins practice at the brickyard. Bright and early on May 1, the
Thompson #83 car (MacDonald's car) and Chuck Rodee's #87 are pushed out for some track time. In addition to the aero skins, there were
many other modifications made to the cars since the March tests, including major chassis & suspension adjustments all in an effort to
resolve instability issues. Mickey's rear wing attachments were still ruled out by USAC officials. Photo courtesy IMS.
Mickey Thompson's new design was a dramatic departure from the traditional open wheel Indy racer. Thompson was a brilliant innovator
and his aero kit's were far ahead of their time but still unproven on these cars, and at the Brickyard. To date only wind tunnel testing had
been performed but now rubber meets road and the question of whether or not the aero skins would counteract the lifting and floating caused
by the 15" tires would be answered. Dave MacDonald's #83 racer pushed to the pit area and readied for initial testing. [The Henry Ford]

Dave ran a strong race at Laguna Seca but came up a bit short, finishing 2nd sandwiched between the Chaparrals of Jim Hall & Roger Penske.
Dave flew back to the Speedway immediately after the Laguna Seca race and was testing the Thompson #83 car again here on May 4th.

Adding further controversy to Mickey's cars was Colin Chapman's discovery of a radical third-wheel steering arm connected to the right
rear wheel of Mickey's racers. This went completely unnoticed by track officials during car inspections. When this news hit the wires any-
one who wasn't already talking about the Thompson superskates, was now. Mickey was a brilliant innovator, and while many of his con-
cepts were revolutionary they didn't always receive proper development time. This was more of an experimental solution Mickey concocted
to help resolve the floating issues. By all accounts it was disconnected by race time.
Mickey brought in several different nose cone configurations from his Long Beach California speed shop in an effort to find a setup
that kept the car's from lifting in the front.

May 13 and Masten Gregory back out for a practice laps in the 84 car. He loses control and slams into the outside wall. Gregory is unhurt
but says he's had enough and leaves the Thompson team. Before storming off he tells Mickey he believes air getting trapped beneath the
enclosed fenders is the major factor in why the cars are so unstable.

Late in the day on May 17th Dave MacDonald is out practicing in between sporadic day 2 qualifying. He rounds turn 2 and the engine on
his Sears Allstate Ford gives out. The Thompson team tows Dave back to the garage. The team had no more engines available and a Ford
engineer told Mickey it would be days, maybe a week before Detroit could send another. Mickey was not allowed to use an engine from
the #82 & 84 cars as Detroit made it clear the priority was to keep them running and get them in the field too. MacDonald wanted the
track time but with nothing to do he flew back to California later that evening to be with his family. Photo Indianapolis Motor Speedway

Still down a racer after Gregory's departure, Mickey Thompson put word out he was looking for an available driver. Bobby Unser brought
young 24 yr old Mario Andretti by the Thompson garage and Mickey immediately offered him the ride. Andretti agreed to come by the next
day and test the car but never showed. Thompson then turned to 15-time Indy 500 competitor Eddie Johnson and invited him to the team.
Johnson accepted but during his initial runs with the 82 car he was only able to get into the mid 140's.
