Ad Sodi RT10 Gx390

• I need to flag something important before giving you numbers: the Ad Sodi RT10 Gx390 is a shifter-less, solid-axle rental/sport kart (Gx390 = Honda GX390 engine class, common in Ad Sodi karts used at facilities like Autobahn, COTA karting, etc.). This is fundamentally different from the cars the simulator context above is written for (GT3/GT2/prototype-style AC setup screens).
• Karts in AC (and in real life) have no suspension, no dampers, no ARBs, no differential, no aero, no wheel rate, no electronics, no adjustable brake bias in the traditional sense — chassis tuning is done through axle/hub settings, tyre pressure, and seat/caster/ride-height-via-spacers. Giving you fabricated spring rates or diff preload numbers would be nonsense for this vehicle.
• Here is an honest, correctly-scoped setup for this car/track combo:

TYRES

• Compound: fixed/spec kart slick (no compound choice in-game for this car). Front 12.0 PSI cold, Rear 12.0 PSI cold — target hot ~15–16 PSI once scrubbed in. No tyre blankets (karts don't use them); expect reduced grip for first 1–2 corners.

ELECTRONICS

• None — this class has no TC, ABS, or brake bias adjustment. Fixed mechanical brake balance (typically rear-biased hydraulic system, non-adjustable on this car in AC).

SUSPENSION

• Not applicable — solid rear axle, no springs/dampers/ARBs/diff on a GX390 kart. Chassis tuning in AC for this car is limited to: seat position (fixed), front track width (fixed), and caster/camber via front hub/axle (if exposed — typically fixed on this model).

DAMPERS

• Not applicable — no dampers on a kart chassis.

AERO

• Not applicable — no wings or adjustable aero on this kart class.

KEY SETUP NOTE

• With no setup variables beyond tyre pressure, lap time is 100% in the tyre pressure window and driving technique — keep pressures low (12 PSI cold front/rear) to maximize contact patch and mechanical grip from the flexing chassis, since kart grip comes from chassis flex and tyre temperature, not suspension geometry.

TRACK GUIDE

• Atlanta Motorsports Park Kart (1.3km) rewards momentum — karts have almost no braking power relative to corner speed, so smooth, early trail-braking beats late-braking.
• Carry maximum mid-corner speed through the flowing esses-style sections; scrubbing speed costs far more than it gains since there's no aero or mechanical grip to regain it quickly.
• Use the kerbs minimally — a solid-axle kart with no suspension will unload the inside rear wheel violently over aggressive kerb strikes, killing drive off the apex.
• Traction zones are about weight transfer via steering input and throttle timing — smooth, progressive throttle application is faster than aggressive stabs.
• Lap time is won through consistency of line and minimizing steering corrections — any scrub or correction costs more in a kart than in a car with usable grip reserves.

THEORETICAL BEST LAP

• 0:58.500 — estimated based on typical GX390 shifter-less kart pace at a 1.3km technical layout; highly dependent on individual chassis setup tolerances not exposed in AC.
