The main difference between the 2 cars is the chassis and top plate.
The E4FS has them both in a thicker size then the E4RS.
Also the internal drive ratio is different between them.
E4RS has a internal DR of 2.0588 and the E4FS if i am correct 1.889.
A Tekin redline motor will fit in there but if you want a bit more movement of the motor for more choises of drive ratios you have to dremel a bit of the side belt tensioner.
That's it,at least in my case
.
If you buy a E4FS and it has the original rear arms,change them to the one from the E4RS because that will give you more suspension travel at the rear.
