Thunder Lane builds hand-assembled, bespoke-valved coilover systems for Mercedes-Benz and Mercedes-AMG — from the W124 classic (1984–1995) and the AMG A45 hot hatch (W177, 2019+) with TL-ONE single-adjustable systems, to the AMG GT R (C190, 2017–2021) with the flagship TL-PRO true 3-way. Whether the car is a preserved classic, an AWD daily that sees track days, or a front-mid V8 track weapon, every kit is built to order and valved to your exact goals.
Every kit is assembled per order in Poland with 46mm electroplated, fully rebuildable monotube dampers and ships with CVP + PVP dyno graphs documenting your valving. TL-PRO adds independent rebound, low-speed and high-speed compression adjustment with remote reservoirs. Spring rates are finalized with you before production begins; lead time is 4–6 weeks. Start with the A45 guide, W124 guide, or AMG GT R guide.
