I have changed all the badges apart from the Engine and the steering wheel.
The wheels caps i ordered from Lexus and cost about £160 UK Pounds.. not so cheap.. but these were shipped over from Japan!
The rest of the badges are glued on with sponge pads type stickers.. very thin and you cannot see them unless you look real close.. but then still hard to see.
The front and back toyota badges do leave holes and you need to make sure you new lex badges cover these holes.
the badge on the steering wheel is not that noticible really.
If you go to our UK site and PM Chris Shipley and ask for the part numbers for the wheel caps then I am sure he will send you the part numbers.
These are official Lexus parts and are for the US and NZ market i guess
