Compomotive MOs 18 x 8, offset can't remember exactly (it's on their site and it was in the 35-38 ballpark area) ... not light about 26 lbs each I believe but pretty much guaranteed not to break. I thought about Magnesium Rims I would of taking Als rims at that price if I'd realized he was selling them but I couldn't justify the price tag of the TE37 Mags much as I adored them. The TE37 Mags are literally HALF the weight of these and still the same dimensions which is just unbelievable.
I'm sure for the price the quality would have been awesome but I've heard a lot of issues with Mag Rims on anything other than perfect asphalt and we don't get much of that in Hong Kong. One thing I have learnt about going fast on the roads here is that you need ground clearance, shocks with plenty of travel and strong rims. With these mods alone you can beat just about any car of equivalent performance to your own because the race shocked, lowered and fancy japanese rim brigade brake, slow down and go over every speed hump, pothole, ramp and crack in the pavement at obscenely slow speeds. If you can just keep going you can close them down no trouble.
