Flatout Suspension Buyer’s Guide: Trail Runner vs. GR Lite vs. GR Plus vs. GR40
When it comes to upgrading your suspension, not all lift kits and coilovers are created equal. At Flatout Suspension, we offer several options — the Trail Runner, GR Lite, GR Plus, and GR40 — each designed for different types of drivers, vehicles, and budgets. Whether you’re looking for an OEM-style suspension upgrade for daily driving or a rally-ready coilover system built for motorsports, there’s a Flatout kit that fits your needs.
In this guide, we’ll break down the key differences between each suspension system and help you decide which is the best fit for your build.
