I haven't seen TK on the forum since last year, but I know his set up. He has 18" rim 8.5" width front and rear. Off set is +35 for front and +29 for rear. Tyres are 225X40X18 front and 235X40X18 rear. His IS250 was orginally the basic model with 205X55X16 tyres all round and he found the wider tyres seemed to give a firmer ride but thought the car was also like carrying an additional 300lb load and had lost a lot of drive responsiveness. He was talking about switching to 225 for the rear in the next tyre change, but I don't know if he ever did this. The UK spec Eibach springs he had fitted give a 30mm drop all round.
Tnx alot :)
