Contact Topline here in the US.
They have their new MAXX struts (80mm) and let you lower your car up to 5". Plus they allow for up to 7" wide wheel under the fender (with the right offset of course).
They cost around $400.
or you could get their tapered springs which also allow wider wheels and dont cost near as much as the MAXX struts.
