With every auto enthousiast on the planet still awestruck by Nissan’s new GT-R supercar, news that top Japanese tuning firms are already offering upgrades may be enough to send them over the edge. Here are the highlights of the upcoming raft of after market bolt-ons for Nissan’s new supercar showcased by Mine’s Motor Sports at the Tokyo Auto Salon 2008.

Mines have developed adjustable coil over suspension, a 400mm brake kit, high-flow catalysts and a more freer-flowing titanium exhaust system. This has already seen a 20bhp hike in dyno tests and the firm is busying itself working on the ECU to allow the car to run higher boost levels.
