Bexus200

I bought a W plate Lexus IS200, when I got the car obviously the fronts were worn on the inside. I got some TopSpeed suspension bushes, new ball joints, new drop links then took the car to WIM for Alignment and had a set of 4 x Goodyear Eagle F1 Asy 2's put on. 4000 miles later those brand new tyres are 100% worn (no tread left) on the inside front tyres, backs tyres still look new..... What Gives?

Hi all. A new Lexus IS200 owner here, 2000 reg (that story later) I have the dreaded knocking coming from O/S front, most audible on rough roads at slower speeds unless the road noise is drowning the sound out when going faster. - Discs & Pads Changed all round - Front lower ball joints been changed - Front Suspension Rear/no2 arm Bush has gone, I have some TopSpeed ones on order - Def need a trip to WIM for alignment & Geo, can almost visually see the wheels are out and car jumps trajectory when going over bumps now - Tyres are not great, thinking of putting on some Goodyear F1 AYS 2 Will report back after those suspension bushes get done and have caliper / pads re-checked for movement. Maybe WIM may spot the problem when I visit if not solved before then (will be my first visit to WIM, any alignment I've had in the past made my car's feel worse)
