What else can Audi do to the R15 to make it worth racing, when it as of now has only won 1/3 of the races entered (3 of 9, though it could've been more if Audi had done things differently or had better luck)?
It's easy to believe that Audi would run wider tires on the R15, for if nothing else to gain info to benefit the R18. And the grip problems arise from mechanical grip, especially since the twin deck front diffuser has been dispensed with, which takes away some of the areo grip that perhaps in the past made up for it. And with the R15's wheel lock clearence bulges on the front fenders are detachable, that provides more fuel for the fire. And we have to add in the fact that sometimes the fender bulges seemed to be a bit wider than necessary for 13'' tires and 13.5x18'' wheels. Of course, it was Mike who started that rumor with the R15 test car at Sebring, and I'd like to hear his theories on it.
Of course, Dagys had heard the R15 "++" rumor as well, and commented on it in his Zhuhai wrap-up in the weekly sportscar blog on Speed.com, but didn't comment any further aside from the fact that the updated R15 will test alongside the R18, and probably will run Sebring. Maybe I should ask him about it, but there's only so much these writers are allowed to tell, at least on the record
