hi just looking for some advice ,i am wanting to buy some bbs lm alloys but they don't 17" with 130 pdc 's they do 18" x8.5 but i have been warned off these as i am told it will make the car tramline ? if this is not the case any idea's for the et's , im running 2" narrowed beam up front with cb dropped spindles and empi disks on an irs back end ,i am told this increases the track width by 22 mm per side on the back which looks about right as the wheels are sat flush with the rear fenders (got 914 5.5 fuches on at the moment ) any way any infomation would be greatly appreciated
