A little feedback....

I have been trying different big bore springs, i've tried losi green front and white rear and finally kyosho yellow front and white rear...The kyosho by far are a better spring and make the car feel great..

On another note:
I'm starting to dislike this hole ball diff situation, it seems like they dont last to long....is the bfast set up any better? I wish the had a gear diff but then again you would have to tear it down to change the oil to different weight...i want to try ceramic balls and bfast washers...

what is this c-hub or c brace i see people talking about?
