Just fitted Dave's " Holden solution " to the Roadster. The new blades are certainly less flimsy than the originals.I did the measuring and cutting with the first cup of coffee this morning before anyone else was up. Trial wipe has the blades in a more perpendicular position to the gjass. All i need now is a good downpour to gauge the effectiveness. Pity i didn't have them for Silverstone last weekend.
