Rear end? How about the entire design? 908 rip-off, bleh. I can't actually see any originality in the design, with the only major difference to the 908/90X test bed being the nose struts being thinner and longer. Thats not much of a difference.
I hope Lola come up with a nice design, their B08 looked great. Had some good engine packages too, with the Aston Martin V12 and the Mazdas..
