I have not driven the LTX, but I do drive an S120L and S120LT. Both are excellent cars. I run the LT in stock, and have run the battery both in-line and across the back. The L has the lipo chassis and on-point pod and tube conversion and the only option is across the back battery. Both cars feel balanced and are easy to setup and drive. Both are currently setup the same, battery across the back, esc on one side, receiver pack and receiver on the other, flat servo mount from the LT on both.
Front end adjustments are simple with the pillow ball setup and ride height is set with metal shims that are easily inserted with just loosening the screws. Rear ride height uses inserts similar to the major brands (minus the CRC adjustable pods now), and they come in small enough increments to easily get the desired ride height. The threaded body posts are awesome, the tubes are all aluminum and very well machined, and the front end is just sexy.
My only complaint is not being a huge fan of the center shock, though that seems to be consistent for most brands. I run the Hot Bodies center shock on all my pan cars with either AE/CRC or Wind Tunnel springs. Front and side springs are all Serpent as they have a variety of rates that have worked well for me. I wish there was a good way to identify them though, as they are all black.
The only parts I have broken are kingpins and one of the plastic side damnpeners. I have yet to break any carbon or any of the plastics. The inserts for the upper hinge pins do develop some slop over time, and I replace front plastics due to feeling like I should more then any actual play forming in them. The ball cups do wear though and I replace those more often.
Attached is my S120LT setup for 13.5 stock. My L is setup for mod and does not have the LT topdeck due to running a fan on the ESC.
