FSGP 2019 Retrospective

Dynamics

Steering

• Steering column separated during egress scrutineering in 3 different places
  • Nylon shear pin came out of the hole instead of breaking as expected, may require longer pin
  • Safety wire failure for the set screws holding steering column in u-joint or possibly never tight to begin with causing the column to come out - reduce friction locking parts in the future
  • Collar on steering shaft was not tightened/possibly does not do much

Brakes

• DFA for brakes assembly, bleeding and removing parts took nearly 3 hours
• Have backups for critical parts (ex: brake rotors)
• Bleeding should be done properly, according to instructions/manuals and multiple people should know how

Suspension

• Swivel joint came out of the shock, compromising the rear suspension
• Was not touched since installation, should look into adding these parts to a maintenance checklist

Motors

• Motor shoulderhead bolts sheared due to bolts coming out and hub with wheel separating from rotor, spacers were used to prevent this but were not in place during competition - spacers were created and installed at competition
• Motor crash due to air gap collapse - NGM 150 had to be reharnessed and spacers installed for air gap

Aerobody

• Transporting caused most of the replaced clickbonds to break off - were replaced again but significantly less strength (possibly due to DP420 vs real clickbond adhesive)
• Issues due to puncturing/sanding too much material for reapplying clickbonds
• Better jig to transport the car in the trailer
• Panel warping
• Trunk panel fell through the side panels multiple times

Other

• DFA for trailing arm, bolt disappeared into a gap between the trailing arm and motor
• More wrenches for appropriate sizes
• Organize spare parts and components better
