Thanks for the reply Kronos
I'm just looking for something a little different from the normal everyday wheels you see about ...I've been looking at Vossen wheels something with a decent concave, one of the main reasons I'm opting to go with 20"s there's just a bigger selection of wheels
I've been going through some of the Americain Lexus forums and some say they have gone as big as 20 x 11 on the rear running a 275/30/20 with no scrubbing, I think that"s stretching it a bit.
I"m trying to achieve a wide and low look, I will be modifying the suspension with adjustable coil overs to adjust the height to suit, I have even considered going down the airbag suspension road
