STLNLST,I have finished every race with my Pro4,The only problem I have had with with my Pro4 was I broke a ring and pinion gear but I did finish the race(I was punted..big time)All I can go by(for me)is how I have done at the track,so far it's the best car for me(and you do know how many TC's I have..
)I have finished in the top 3 every time I have raced this car..
and the track I race at is not really a "one way" track so I did pick up a diff for the front(have not raced with it yet)Just my 2 cents..I think any Touring car can win it's still in the set up and motor/battery combo. I have a TC-3..I dont win with it,I have a Pro4 and I win with it,does that make the Pro4 better,No..just better for me and the bottom line is I just like the way the car works..
