Been using my quickshift for about five weeks now.
Verdict:
Great mod for the money, not too much hassle to fit. It has made the shift a bit stiiffer but I am sure it will ease off as the new bit beds in.
Best of all tho is the change up from 2nd to 3rd and 3rd to 4th, it's so quick, get in tune with the car an the shift and it really makes a huge difference especially on a nice open road when you can just floor it from gear to gear.
If you have not yet got one, get one.
