If you’ve been waiting for Nissan’s GT-R V-Spec, you’ll have to keep waiting.  Nissan has just delayed the launch of the lightweight GT-R V-Spec until early 2009.  However, Nissan is getting ready to launch their NISMO performance parts catalog for the GT-R on august 20th.  We can expect many of the popular tuner companies, such as Stillen and GReddy, to produce performance products for the GT-R as well.  However, there is a new company stepping into the ring – GT-RR.com, GT-RR.com is a distributor of “high-end boutique” performance parts for the Nissan GT-R.  On its Web site, you will find a robust list of cutting edge news and product from the global GT-R tuning world.  GT-RR is dedicated to bringing you the best performance parts made from the best materials.  You can expect to find lightweight titanium exhausts, top quality dry carbon fiber aero products, big brake upgrades, coil-over suspensions and custom wheels.  As a subsidiary of Bulletproof Automotive, GT-RR.com is backed by more than 15 years of JDM parts experience. Improving the already stellar performance of the Nissan GT-R is not easy.  GT-RR’s strategy is twofold: increase power and reduce weight.  GT-RR offers a number of high-quality performance exhaust upgrades that not only improve and sound and performance of the GT-R, but also cuts several unwanted pounds.  For example, the stock GT-R exhaust weighs roughly 35 lbs.  Switching to a high-flow titanium exhaust can cut as much as 15 lbs from the rear of the car.  Furthermore, a full exhaust upgrade, including the y-pipe, high-flow cat and cat-back system, can add up to 30-40 horsepower. GT-RR also offers a number of aero upgrades including carbon fiber front splitters, rear wings, diffusers, side skirts, air intake ducts, canard systems, and more.
