As quoted from people who spoke to Lotus at the LA Auto Show, the SS wheels weigh in at 7 lbs less in the back and 4 lbs less in the front.
According to Rimstock's website, even their racing wheels in 17 x 7 are not less than 16 lbs, which would mean that the stock 17" rims (on the rear) would weigh in at around 23-24 lbs? And those are supposedly lighter than the S1 wheels (according to Top Gear)?
Does this seem right or we getting some number inflation here? I suppose it's possible that these Rimstock wheels made for Lotus are wildly more advanced than their other wheels or that the stock Lotus wheels are horribly overwieght - neither of which sound really true. Maybe they meant wheel and tire weight combined?
