XRAY - Model racing cars

fit a diff in the front, it stops the car piviting as much. you could try the spool, its cheeper, but it eats the plastic over guides on the drive shafts.you always have too much front end with an Xray....

u could try blue springs rear and violet front maby that might help

did it suddenly happened? that you last time could drive normal, and just in once the next time it breaks out on the rear every corner, if that is the case, you should check your rear diffenrential, big chance problem is there. Take out your diff and open it, the two metal rings on both sides of your diff balls, might me worn. Than you'd better replace them, or scour them. or maybe you car is tweaked,

All the above is good advice. I would also recommend changing to a less aggressive body as the Mazda 6 gives a huge amount of steering. Try a Stratus 1 for instance. Also, reduce the wheelbase by one or two mm.
