No problem for me, just need the drop and KP centerline along with your spindles.
custom 36"- 2" offset- 5'drop - SPE spindles
If you are running an index class I II III, (and because you cant go deep in staging), you want a straight up front axle to stage consistantly, and offset axle opens up a 10" window of shallow or to far in and will affect your times. Too shallow and you will run the tree and lower ET (slow RT) or in too far an your RT decreases but the ET slows. In 7.0 with offset and staging deep (Legal) the front is in the same spot everytime and the track gets shorter
