Thunder Lane builds hand-assembled, bespoke-valved coilover systems for Mitsubishi's rally-bred AWD icons — the Lancer Evo IX (CT9A, 2005–2007) with the TL-ONE single-adjustable system, and the Lancer Evo X (CZ4A, 2008–2015) in both long-stroke TL-ONE and true 3-way TL-PRO form. Because every kit is built to order and valved to your exact spec, the same Evo can be set up for tarmac track duty, gravel stages, or a compliant street ride.
Every kit is assembled per order in Poland with electroplated, fully rebuildable monotube dampers and ships with CVP + PVP dyno graphs documenting your valving. The Evo X TL-PRO adds independent rebound, low-speed and high-speed compression adjustment with remote reservoirs for drivers chasing consistency across long sessions. Spring rates are finalized with you before production begins; lead time is 4–6 weeks. Read the Evo X buying guide or the Evo IX guide to choose your setup.
