Flatout GR Plus 2” Lift Coilovers for Porsche 991 C4

The Flatout GR Plus 2” Lift Coilovers deliver Porsche 991 C4 owners the ideal balance of daily driving comfort, added ground clearance, and rally-inspired durability. Offering a 2-inch lift (adjustable 0–3”), this complete coilover kit provides greater strength, control, and adjustability than the entry-level GR Lite—at only a modest price increase.

Positioned between the GR Lite and GR40, the GR Plus offers rally-strength suspension and off-road capability while remaining practical and comfortable for everyday driving. It’s the best value for drivers who want performance without stepping up to full competition-level suspension.
