• RECENT PERFORMANCE HISTORY
• I have raced the car one time in its current set up. The
suspension upgrades were accomplished in 2013 and I did have a
couple events on it that year. All of the fuel system, distributor,
MSD and CIS work was accomplished in late 2013 after the close of
the racing season. The car ran the 2014 Sebring Club Race but I was
forced to use an open diff and had shift coupler issues all
weekend. Thus the new WEVO shift coupler, gearbox rebuild and
Guards limited slip installation in February/March 2014.
• I ran the car at a DE at Mid-Ohio in April 2014 and had to move
my shift points as I bumped the rev limiter in two places on the
track I did not need to shift before. I also ran the car at a DE at
Watkins Glen in early August 2014.
•
) The car ran very strong and handled great. The only limitation
was the old Hoosiers that had been on the car since May 2013. I
lost track of the number of heat cycles and days of freezing temps
they endured. Wear is surprisingly even across the tires. Between
those events, I replaced the axles, CV’s and rear wheel
bearings.
• After the Watkins Glen event, I rebuilt the pedal cluster. I
raced the Car at the September 2014 PCA Club Race at Mid-Ohio and
set a new lap record for D Class.
