I ordered a spec stage 3+ so that should grip pretty good. I test drove a buddies car today that has the spec and it will take some getting used to for sure, but when it is released....its released. I will probably break my half shafts now, but that will give me more reason to upgrade
I ran a Spec stage 3 with my 2V setup and I liked it a lot. If you can avoid wheelhop your halfshafts may hold up ok. Wheelhop is what killed my Moser 31 spline axle in my solid rear.
