If I buy the stronger 12 bolt rearend for my machine, could I still use the car for open events and auto cross?

 

Yes, only you added more weight to the car.

 

Thanks for the answer, I figured as much. I need to figure out a way to have a stronger rear without adding weight.

 

i have 2 thoughts for ya'
1) add the 12 bolt with the extra weight and find a way to remove the weight somewhere else
2) beef up the 10 bolt rear

compare the cost and the end result you are looking for and go for it!!!
