🔴 LIVE | Pt.2 | Car Setup Development | Q&A | Stock Car Brasil 2019 | AMS2

Welcome to the stream! Today, we're delving deeper into the setup we started developing in Pt.1 I shall explain the learning and developments that have been made behind closed doors over the last week, and then demonstrate how the improvements manifest on track, with what I hope will be a smooth race. The race will be a full replica of the real world format for this series, 45mins+1Lap at Interlagos (for direct comparison to Pt.1), with a mandatory stop for at least 1 tyre. If time allows, and to demonstrate the changes required, I may do a second race, at Velo Park, same format. ------------------------------------------------- Video time line 00:02:35 Introduction 00:05:40: Setup development since Pt.1 explained -- Clarifications -- 00:11:50: Priority of Changes 00:17:05 Dampers - Chat 00:24:25: Dampers - Simplified 00:27:25: Diff Simplified -------------------------- 00:33:30: Race 1 - Interlagos 01:33:00: Race 2 - Velo Park (Attempt 1) 01:59:35: Race 2 - Velo Park (Attempt 2) 02:48:30: Summary and closing out ------------------------------------------------- CAR SETUP GLOSSARY & QUICK REFERENCE: Brake Balance (Bias): The percentage of braking force sent to the front vs. rear wheels. A forward bias increases stability under heavy braking; a rear bias helps rotate the car on entry (too much rear bias causes trail-braking spins). Brake Duct Openings: Controls airflow to cool the brakes. Smaller openings increase aerodynamic efficiency and keep brakes hot; larger openings prevent brake overheating and fade at the cost of slight straight-line speed. Caster: The backward angle of the steering pivot axis. Higher positive caster improves straight-line stability and dynamic camber in corners, but increases steering effort and corner-entry weight transfer. Camber: The vertical angle of the tires relative to the road. Negative camber keeps the tire tread flat on the asphalt during heavy cornering, maximizing grip through turns (excessive camber hurts straight-line braking/acceleration). Ride Height: The distance between the chassis floor and the ground. Bump Stops: Rubber buffers that limit maximum suspension travel. Increasing bump stop stiffness (or shortening travel gap) prevents the car chassis or floor from bottoming out, stabilizing aerodynamic platform performance. Damping: Controls the speed at which springs compress and expand. Dampers absorb energy to keep tires planted over bumps and transition weight smoothly. Bump Damping: Controls how fast the suspension compresses when hitting bumps or loading up weight. Higher bump stiffens dynamic weight transfer; lower bump absorbs kerbs better. Rebound Damping: Controls how fast the suspension expands back after being compressed. Higher rebound slows weight transfer release, holding the car down or stabilized through transient directional changes. Toe In / Out: The angle of the tires relative to the centre line when viewed from above. Toe-In: Tires point inward; increases straight-line stability. Toe-Out: Tires point outward; sharpens corner entry response at the expense of straight-line stability and tire heat/wear. Anti-Roll Bar (ARB): A lateral torsion bar connecting opposite wheels. Stiffening a front or rear ARB reduces body roll, shifting mechanical grip to the opposite axle (a stiffer front ARB causes understeer; a stiffer rear ARB causes oversteer). Clutch LSD (Limited Slip Differential): Manages torque delivery between drive wheels to optimize acceleration and turn-in rotation. Pre-Load: Static resistance in the differential before wheel-speed differences occur. Higher pre-load stabilizes off-throttle to mid-corner transitions. Clutches (Plates): Determines maximum locking torque capacity. More clutch plates increase the diff's locking force under both power and coasting. Power Ramp: Angle governing lockup under acceleration. A lower angle/higher locking rate delivers power evenly to both rear tires for maximum traction, but encourages exit understeer. Coast Ramp: Angle governing lockup during deceleration/engine braking. Higher locking under coast stabilizes the car during turn-in; lower locking allows sharper rotation into apexes. ------------------------------------------------- AMS 2 Software Version: 1.6.9.91.3398.AVX ------------------------------------------------- Additional Software: Second Monitor: https://forum.reizastudios.com/thread... ------------------------------------------------- Equipment Used: PC Specs: Processor: Intel Core i7-11700F RAM: 32 GB Graphics: NVIDIA GeForce RTX 4070 12GB GDDR6X OS: Windows 11 Monitor: AGON 49" @ 5120x1140 Headset: Logitech Pro X Wired Steering Wheel: Cammus C5 Pedals: Fanatec CSL Elite V2 Sim 3D Rumble Motors Shifter: SHH Thorn Rig: GT Omega Art Cockpit Cobra Clubman Seat ------------------------------------------------- #ams2 #automobilista2 #reizastudios #reiza #simracing
