I don't see the huge value in the new car.
**Adjustable belt tension front and rear. Nice, but you have to tear the whole car apart to change it.
**New brake arm.
**New gear ratios. Some say new pulleys but the way I read it, there is new gears and it sounds like they are stronger maybe.
**New bulkheads that give you a 2 position wheelbase adjustment. It says width can be adjusted 3mm but I think they really mean length.
**New front upper a-arm mounts that change the geometry somehow.
**New fuel cap similar to Serpent's AFL cap. I run a chamber and have never had a problem.
Again, I don't see anything super spectacular on this car from mine, do you?
