Went to track for the last time of the year and I think something broken ? I gottwo passes 11.62 heard a big crack and now only one rear wheels spins while doing burn out now ,went 12.06 spinning 1.98 60'foot. If i need to replace what would be the best option (I do drive on the street) I will pull everything apart this weekend.

 

Think that depends on what broke. Let us know what you find when you take it apart.

 

if only one wheel is spinning then it sounds like something with your posi broke. time to upgrade!! brenspeed has one for 380?
