RacingLine’s extensive development program has specified progressive rate springs to preserve the ride quality in normal use, but then stiffen the rates at the ends of the travel. This progressive-rate spring construction means the spring rate in the middle of travel is very similar to standard. It's only towards the end of the spring's travel (so, when braking or cornering hard) that RacingLine have engineered the spring to stiffen up. It's this progressive-rate spring design that is the secret to such good ride quality combined with dynamic performance.
The Sport Springs are developed to be fully compatible with cars fitted with the Octavia's switchable DCC (adjustable chassis control) dampers.
RacingLine’s Sport Springs are high quality, European-made springs, from the same factory that produces many of the OEM springs.
This should first upgrade to make to your car, give it the ride-height it deserves!
