STI SHORT THROW SHIFTER
(Part No. C1010AG001 [5M/T])
A short throw shifter reduces the throw distance between gears. Resulting shifts are crisper and quicker, which enhances the fun of driving.
The installation involves work both in the cabin and underneath the car.
Prior to beginning disassembly, disconnect the battery.
