+8mm or + 11mm are for new chassis' that are already longer than that brand "kit" chassis, e.g. durango 210 or AE b4.1 worlds.
I'd need to refer back to websites/manuals to find exact wheelbase measurements of other cars compared with the Bmax2 MR kit, but I've never thought "oh i really need that extra +8mm chassis". The car just works and works well on low traction, medium and high traction tracks.
Another feature of all the BMAX2 MR cars is the ability to build them as mid or rear motor. I have one of each for the different tracks I run at, but I like to have a spare car ready to go, rather than swapping all the time.
It's a great car.
