Integy Rear Hubs... they seem decent enough. However, fit and finish wasn't greatest. I had to grind down the ball in the upper tie rod end to get it to fit. Also it was a damn tight fit with the bearings!! Should have taken a dremel and ground them out carefully, but I was in a bit of a rush so I suspect the bearings just won't come out!
Other thing is there aren't any instructions so you really aren't 100% sure what degrees of camber the three optional mounting points are. Will need to get out camber gauage and measure. I did use the #2 mounting point(#1 go #2, #2, go #1... ) for what I believe is 2 degrees of camber.
Put together with the XL axles and the 24mm HPI hub adapters.
Pic of them mounted (sorry unlike others, I am not doing shot by shot mounting instructions!).
So now after all that it does a great job of elimanting the slop in the rear end which should help the vehicle track a lot better. I realize that HPI saves money by using the same part on both ends, but they really need to make a plastic version of this as standard equipment.
I also tossed in the HD drive gear set into the gearbox.
Next up... I did actually take some "advice" and got some shock "socks" from badhorsie, so we'll see how those work out (or don't).
Following that, I am probably going to grind out the TVPs some to make room for a CC1520 1Y and run 6S instead of the 5S I am now. Although the CC1512 1.5Y would be a nice middle ground and its actually shorter than the CC2200 so no mods would be necessary to the TVPs.
Think I will also work on some lexan mud guards for the rear arms.
