having now had my 4/4 for over 18months I also needed to do some enhancements to improve the factory setup .
First was the Revolutions induction kit with K&N filter this made a real improvement but 5th gear was not much good .
Next on the list was a librands manifold and a trip down to Williams for a remap and while I was there they fitted a Panhard Rod,i also have brake reaction bars .
I had a 400+ mile journey home and I found a huge improvement in driveability. 5th gear is now not just a cruising gear and I am now happy with the car .
However 2weeks ago she was shipped back to the factory to have some paint bubbling on both wings fixed ,thank goodness for a 30 month warranty.
