Chasis or trans, mounted TA
The chassis mounted torque arms are going to weigh more.. ours are right around 10lbs more than our transmission mounted arms. But with the chassis mounted set-ups you get the torque arm off the transmission and mounted to a more secure location so usually the extra weight is beneficial.
For what to choose depends no what you are looking to gain and how you drive it.
If I can help anymore please ask. Thank you!
