Porsche tuner 9ff {link} have turned their attention to the GT2 with impressive results. Using traditional tuning techniques in conjuction with modified electronics 9ff have been able to improve the performance of the GT2 considerably.
Whilst a standard Porsche GT2 offers a more than adequate 530PS 9ff's GT2 offers up to a stunning 910PS with a similar increase in torque. Combine all the extra power and torque with a new exhaust system, radically improved suspension and braking and 9ff's GT2 becomes and extremely capable and stunningly fast track day car, it is also a fiendishly fast road car!
