2 vs Car Performed well but: Cornering Suspension Intake Manifold Oversized Resolutions: Suspension redesign Intake relocated Frame reductions Braking Stability

3 Frame 95 th percentile 10” diameter impact Safety factor above helmet Imaginary line from mid hoop to main hoop

4 Main Hoop Mid Hoop Front Hoop

6 Frame

7 Vent hood Fabricate Sheet Metal Plastic Ductwork 1 Phase Motor

8 vs Suspension Pull Rod Poor cornering Limited adjustability Push rod Adjustability Improved Handling

9 Front Suspension Lightweight Uprights Improved Roll Centers Incorporates Caster and KPI Improved Camber Gain

10 Camber Change Calculator

11

12 Camber Vs. Steering Input Calculator Excel Calculator Developed to Output Camber Angle for Varying Caster, KPI, and Steering inputs

13 Redesigned Lightweight Uprights Lengthened to Improve Roll Centers Overall Weight Reduced Constructed from 6061-T6 Aircraft Grade Aluminum

14 Coil Over Redesign Proper shocks can correct handling problems Stiffer shocks heat up tires faster 1 to 1 rocker ratio

15 FSAE PS-78PB-DA

16 Rear Suspension Change from Pull-Rod to Push-Rod System Suspension articulation will be increased Redesigned A-arms to eliminate bending moments

17 Rear Upright Design Weight Reduction Adjustability Room for Brake Caliber Attachment Adjustable Toe- In /Out

18 Ackermann Steering Geometry

20 Rack-and-Pinion Steering

21 Wheels Carbon Fiber Wheels Over budget Aluminum Magnesium

22 Braking Force per Individual Brake 60% in the Front, 40% in the Rear

23 Brake Selection Moved to 2+2 Braking System Will utilize same calipers, master brake cylinders Different size Rotors for braking distribution Modifications to rear and front uprights in process Splined Rear Wheel Hub Splined Rotor Mount Brake Caliper Bracket

24 Selection Criteria Based on Car & Driver mass of 310 kg (Last years car + 90kg driver) 3 second stop time from 50 mph ( m/s)

25 Braking Components 1-3/4” Splined Rotor Mount Wilwood GP2000 Single
