What made you choose this particular product?
The roads in the UK are very poor quality so the aim was to improve the ride quality over the OEM suspension whilst increasing road feel and handling characteristics. The PSS10s were modified to allow additional suspension travel at low ride height. This in combination with the other chassis modifications allow for a very competent 'fast road' set up, confidence inspiring even on the worst road surfaces.
Is this your first time buying from this brand? Did you consider other brands?
I considered Nitron and Intrax however they were much better suited to track application so opted for PSS10 for the road
