Technology
Every ThunderLane kit is specified as a matched package of springs and dampers, then built and valved to order at our factory in Poland. European built, proven across the world.
Setups for every use, from fast road to full competition. TL-ONE coilovers can usually be upgraded to TL-PRO coilovers at a later date.
Non-adjustable
Fixed damping, custom valved for your car. Because the valving is specified for your chassis, tyres and use from the start, TL-CORE is better controlled out of the box than most 1-way adjustables on the market.
1-way adjustable
Rebound-adjustable dampers with a check valve design. The adjuster has a large effect on low-speed rebound for platform control and response, with much smaller changes to high-speed rebound and minimal change to compression, so you can tune how the car settles without making it harsh over kerbs.
3-way adjustable
Independent low-speed compression, high-speed compression and rebound adjustment for dedicated track and competition cars, where repeatable adjustment between sessions matters as much as outright grip.
Spring rates and damper valving are chosen together around your chassis, weight, tyres, ride height, modifications and how the car is used.
Each damper is assembled to order at our factory in Poland and valved to its target force curve.
Every damper is tested on the dyno, and the graphs ship with your kit so you can see exactly what it does.
We're confident in our work, so every kit ships with its own dyno results: force vs velocity and force vs displacement graphs.
