I'm sticking with mine. Big bore shocks aside there's not a lot of difference and I'd be very surprised if I or any other average club racer would be able to go any quicker with them anyway!?
The chassis with the industry standard lipo cutouts is good and if you haven't already replaced your old chassis with the new type (assuming it's the new-ish stiff chassis?) you can dremel the holes into the old style chassis for free anyway.
Maybe the new plastic pivot pin hangers will be less prone to damage so they could be a good thing to add to an old car. The plastic steering arms and bearing housings must just be a cost cutting exercise though which is why the SX2 is being priced less than the SX?
Don't get me wrong I would like a new car, but it's hardly very diffeent to the old one + it's got more plastic bits on it! Cue SX2 owners upgrading from plastic to alloy bits................
