I'm actually driving Vone R4 since april and never had a problem with diffs... when the people star to comment about it, I look on my rear diff... it was working well but a little rusty... so I shimmed and until today never had a problem... a friend has problems... two diff broken...
Im very hapy with the car... is faster than my older Nt1...and I the car can go much faster than now...
With Nt1, I nkow what was the limit...with R4 I don`t know the limit of this car...I'm very happy...Nt1 brakes a lot of belts...R4 has a solid transmission...but the front bumper brakes...(just ones...but breaks...)...and the rear arm breaks in comparison to the unbreakble arm of nt1...but I really prefer R4 solid performance!!!...I`m very happy, I`m actually in 1st place in the national championship...and I 'll win it!!! jojojo..xD
The improvements of the optional parts make rear end more quicker and is able to follow front better.
Yes roll center is also changed.
Is necessary to change both of them. I used only one of both because i forgot to buy the other.
For front bumper use VZW411 it makes front little stiffer. Car is fast and will go faster.
Check the option parts which i changed to my car here
Last when steel diffs released bought them and the alum diff case.
