I guess the simple question is how much can you shorten a T4. A half inch or so would be plenty. Can you swap in a B4 chassis?
Just asking because I've got a body that would work much better on a shorter chassis.
LMK, thanks.

You could use the B4 for short, or B4.2 (+8) for medium, but you will find both to be twitchy or harder to drive than the longer T4 chassis, it is much more stable!

You can in fact use a b4 chassis but it will be much harder to drive like slotcarrod said. If you want to make the t4 into a buggy, the j82 conversion kit from jconcepts is really cool
