Thunder Lane builds hand-assembled, bespoke-valved coilover systems for the Lotus Exige — custom-length dampers matched front and rear to the Exige's featherweight, mid-engine platform. Choose the TL-ONE single-adjustable system with nitrogen reservoirs and 20-click rebound, or the TL-PRO true 3-way with independent rebound, low-speed and high-speed compression adjustment and remote reservoirs for time attack and competition duty.
Both kits run 2.25" springs with spherical bearings and digressive valving, and every set is built to order in Poland — fully rebuildable, re-valvable, and shipped with CVP + PVP dyno graphs documenting your exact configuration. Spring rates are finalized with you before production begins; lead time is 4–6 weeks. Read the Lotus Exige coilover buying guide to choose between TL-ONE and TL-PRO for your build.
