Just got mine two days ago for my TPI '76 280z. 15x7 pro series with 4in BS. Fit great. Diamond is real nice to deal with but they are low tech. Fax and phone is the only way to get a tracking number or submit your custom wheel order. I was suprised to have a $30 steel surcharge and they took longer to make than I had hoped but they were cheap ($350 delivered to FL) and look good on a red car. One note, the small dish resulted in the valve stem placed on the backside with access through one of the D-shaped holes. I called and was told that they place them there to prevent wheel-to-wheel rub from knocking the stem off on the track. Luckily it cleared the 4x4 toyota caliper conversion, barely. Your wide wheels will probably not have that issue. You will also need to double check that the size wheel you want is available with the small 9/16" holes (for 1/2" studs) if you still have the stock 12mm. Most stock car wheels are drilled 11/16" for 5/8" studs.
