Tomei 2-way Grip Review

[Flybert]

I've been driving with the 2-way for a couple of weeks and have a done a few canyon runs to comment on its characteristics. I used to have an open diff so any differences I talk about are comparison to that. Also, this all based on canyon driving.

What I've noticed from grip driving with a 2-way is that the lines you take must be very smoothe and you must limit any jerky steering motion that you make, otherwise it is pretty easy to break the backend loose especially when going over slightly uneven pavement. I've also noticed that when you gas it coming out of turns that the back end kind of feels like you have 4-wheel steering and it just follows you nicely. It distributes the torque beautifully. One other thing that I noticed after driving around on it for the first week is the backend just feels planted better in the turns. I've done a few donuts and it is immensely easier than with an open diff. I've also tried kicking out the backend with a clutch kick and that was much easier as well. I'm just waiting to get out on the track to actually try something cool.

As for the clunking, a lot of the clunking has gone away after breaking it in and driving it around for a while but it still clunks really loud on sharp turns like when you're parking. I've also noticed a high pitched hum on occasions when driving straight. I'm not sure if it's coming from the diff but it sounds like it is. It's a new sound that came after the diff install so I'm pretty sure it's from the diff. The only other thing it could be is my stupid driveshaft. I think it's not balanced or something because I accidently disassembled the big rubber bushing when doing my KA swap (we thought we could leave part of the driveshaft in the tranny) and I'm not sure if it's lined up right on the diff.
