Hello, we can supply you with the above kit for £730 which consists of the front valance, rear valance and side skirts. The main kit we are doing is the kit pictured in Fast Car (Koncept kit) this month. For the same kit (front valance, rear valance and side skirts) it works out at £580, but you do need a centre exit exhaust (which we can supply) to go with the rear valance. The rear spoiler on the car in Fast Car will be available very shortly for £185 (all prices inc VAT). We are also in the middle of adapting the side skirts from the Knocept kit to fit the 172 as well as a fully programmable nitrous system.
