Radical SR10

A mid-engined Radical sports prototype: aero where speed allows, and a light car that punishes clumsy inputs when the wing is doing less.

Commit where aero is alive; be precise where it is not. Braking zones decide most laps.

Symptoms this car reads differently

Steps out on entry

Light rear under hard braking. Soften the release.

Nervous at high speed

Do not lift mid-corner at speed. Settle first.

Snaps on exit

Turbo arrives quickly. Open the wheel first.
