Dinan Adjustable Coil-Over Suspension – BMW M3 / M4 (G80/G82/G83) #D190-8210

OVERVIEW

Dinan's adjustable coilover system for the G80 M3 and G82/G83 M4 retains the factory Electronic Damper Control shocks while adding threaded collars for user-adjustable ride height, front and rear. Retuned springs sharpen turn-in without giving up the EDC comfort/sport switching the car came with.

Spring rates run 15% stiffer up front and 10% softer in the rear versus stock, giving up to 1-1/8" of front and 2-1/4" of rear lowering (or up to 1/2" front and 1-1/4" rear of lift) for corner-weighting and stance adjustment. Dinan's recommended drop is 7/8" front on M3 (3/4" on M4) and 3/4" rear.

TECH RESOURCES

Additional Parts Required

• A four-wheel alignment is required after installation (service, sold separately). Verify tire clearance at your target ride height before finalizing fitment.

Installation

• Dinan installation instructions – D190-8210 (G8x M3/M4 coilovers)

Notes

• This part number was split out from a multi-SKU draft listing that bundled it with the G87 M2 coilover, both anti-roll bar sets, and the tension strut ball joint kit as additional variants; each of those part numbers has its own individual Speed Logic listing, so this SKU has been given its own listing to match.
• Dinan's own product page for D190-8210 lists fitment simply as "2021-2026 BMW M3/M4" with no separate part number or fitment split for xDrive — both RWD and Competition xDrive trims are listed on one row below per model. Coilover geometry can differ meaningfully between RWD and xDrive front subframes, so if you're ordering for an xDrive car, confirm current fitment with Speed Logic or Dinan before purchase.
