Product Details
These Riaction GT1 G82 M4 coilovers fit the 2021+ BMW M4 RWD (G82).
Riaction makes this GT1 kit, part number BM-088-LT, for the rear-wheel-drive M4. The all-wheel-drive M4 xDrive takes a different kit, BM-092-LT. Each corner uses a monotube linear damper with 32 levels of damping adjustment, and full-length ride-height adjustment sets ride height without changing spring preload. Spring rates are 8 kg/mm front and 14 kg/mm rear. The kit is fully rebuildable and carries Riaction's 2-year warranty against manufacturing defects.
