Thanks! Yeah track width is definitely wider. The kit is supposed to add 2.5" per side, plus the new rims have less backspacing so that makes it a bit wider as well. So far on-road performance has been better than I expected. I can definitely feel a bit of a difference, but it really isn't that much. Maybe feel a bit more sway in turns, but really not as much as I was kind of expecting.
As for going with Baja Kits, it pretty much came down to price/practicality. When I first started looking into it a couple years ago I definitely was thinking Mazzulla. I think they re-did their "mid-travel" kit a year or so ago though. The new one looks amazing and I like the ability to add a second bypass shock in the mix fairly easily. However, it was a little bit more expensive. It was also a bit wider and I was under the impression that I would pretty much need to go with glass fenders which I did not really want to commit the time/money to yet. I also got really great service from Baja Kits when I was looking into it this spring and took advantage of a sale and just went with it...
