B44.1 is like the b44.. but better. The V2 shocks are spot on! Not stripped any diff gears yet. The new motor mount is brilliant and saves the hassle of putting a driver through the back of the car to get at the screws.
The 44.1 shock towers are also thicker so are less prone to cracking.
Plus the advantages of having setups on hand from AE/CML drivers trackside.
Any more questions please ask
