Awesome upgrade! Increases steering throw and is super crisp. I had to fail down servo throw on my savox to 85% because the links would bind with the drive line housing. I would highly recommend this to anyone looking for a all-in one upgrade. The down side and the reason for 4* instead of 5* is the drive shaft/axle has thrown the pin that slipes into the CV on differential. RcMart was quick to warranty it but after losing my second pin I'm going to drill and tap the pins in with a set screw.
if you're looking for a new upgrade for your RS4 Sport 3, look no further! your sport 3 is not complete without this set! the parts look awesome and are a very good replacement for your stock parts. copy link below for a quick product video: https://www.youtube.com/watch?v=Z3ybxuATcCU
