I'm with both of you. My stock FS shocks worked flawlessly and no leaking. If I needed replacement shocks though I would use either the Tamiya which we all know are great or I would use the Schumacher shocks that come with the MI4 or MI 3.5. They are almost 100% identical to the Tamiya ones but with a thicker hard coating on the shocks.
I had the older E4LE version and those shocks were very difficult to work with. The threads were cut very fine and easily crossthreaded, the machining was rough, the sharp edges cut the bladders.
I had a set of Tamiya TRF shocks from an older car and moved them to the E4 along with the Tamiya lowered spring retainer so I could use the TM springs. Best thing I ever did to improve the car.
That being said, I understand that the new version shocks on the RS and FS outperform and is a much better quality than the older version. I used the Tamiyas because I had them and didn't feel like spending an extra $100 for TM shocks.
