The biggest complaint with the GT4 from many quarters including journalists and drivers is the gearing of the transmission - there is just not enough power in the 3.8L engine to take advantage with the chassis.
Ideally all gears should be changed, but there is no availability for 1st and 2nd gear.
However here at 9e we can offer two different solutions. We can change 3rd, 4th and 5th gears leaving the original 6th gear in place or we can change 3rd, 4th, 5th and 6th gears. The latter is ideal for those who are not concerned by a shorter top speed.
You can see the impact of the changes in the picture.
All installation is done in house by our tecnhnicians.
