KW high-performance racing springs are made from specially alloyed and tempered spring steel and the increased endurance of the material enable new spring constructions with reduced wire diameter. Therefore the springs are up to 30% more efficient than conventional racing springs.

At the same construction length this means:
- More spring travel
- Higher block load
- Less weight

Another reduction of the weight can be achieved by shortening the construction length of the springs and adapt to the required block load.
- Shorter spring construction length
- Improved wheel clearance
- Further weight reduction
