MRG MotorSports 818S Build

[Bob_n_Cincy]

Today we went to Wilmington OH for a test and tune. Only 16 people attended as it was a last minute add to the schedule. So we got in about 60 runs between Michael and I. At one point we did 4 runs in 8 minutes then stopped to take temp readings.

A couple of week ago we went to an event only to come home after our first run with our new tire set up. Everything rubbed in a 25mph easy corner.

Over the last couple of weeks we changed ride height, roll center, suspension mounting points. springs rates, shock length, ball joint length, shock bump stops, camber gain and all the alignment parameters.

WOO HOO
The car drove like it was on rails.
No rubbing at all.
All tire temp within a couple of degrees across individual tires. 130* fronts 160* rears.
Brake pads were 150* front 180* rear.
Engine cooling and AWIC working great.
Our oversteer problem is gone with a slight push.

Changes needed
Add cooling fan override switch to turn the fans on high before runs.
Add brake proportional valve to rear brakes.

We are doing the happy dance As Sgt. Gator would say.

Another autocross tomorrow in Columbus IN.
