what size wheels? 40 offest probs the furthest u can go without major problems. if your on 15's, you'll need to make sure that your tyres are a 195/45/15-low profile. would also advise cutting the bolts off the arches at the rear.

PCD 100 - Pitch Circle Diameter of 100mm. Size of the circle that would be drawn if it went through all bolt holes.

ET 40 - Offset in mm
TB x L12 - Possibly Terbium which is a metal element. Not sure about L12. Something to do with alloy compound?
6 1/2 3 x 15 H2 - 6 1/2 inches wide. The 3 is possibly the bead profile, this is usually expressed as a letter, normally J on normal car tyres, but might be a different letter/number. 15 is rim height. H is a speed rating, 130mph, designed for H rated tyres I think. Not sure about the 2.
