Alpha 9+ R35 GT-R


I have a 2011 GTR and just installed my Alpha 6 package, and boy is it fun! I am extremely happy with not only my car's newly added performance and drivability but with the professionalism provided by AMS. The whole team at AMS will take the time to explain every detail and lay out multiple options for any individual's needs/ goals or wants.  My car is more exciting every day because of AMS.

The AMS alpha 9 kit can be summed up in one word… Perfect…..

With stock drive ability on the street and massive performance on the track it truly was perfect for us in the One Lap of America… Not to mention the rock solid reliability…

From a drivers stand point it’s all about management and power curve.. Being able to use the power at hand and having enough power to smoke the competition…. With a conservative road race tune we saw over 600 wheel HP and a flat tq and power curve… As a driver there isn't much more  i can ask for.. with tq down low to pull out of the low speed corners and Power up top to hit 180+ mph on the straights… 

This kit is a "no brainier" for anyone with a GTR looking for optimum performance of the car… whether it be drag racing, autoX, or road racing…. (we proved that with wins in all those events during OLOA 2011)….

To sum up the ALPHA 9 kit into one word would be "FLAWLESS".  Being able to use aftermarket parts that have if not better then factory reliability is awesome in any motorsports program. The AMS Alpha 9 kit gave us the ability to make more power than stock while keeping the mapping on the ECU safer then it comes from the factory.   I can say without a doubt there isn't another kit I would recommend for any GTR daily driven or tracked.

I have built over 30 cars with almost every major tuner and I can tell you the level of service professionalism and attention to detail is the best in the industry .I think anyone who has built a high performance car can relate to broken promises missed deadlines and cost over runs .AMS has always delivered on time and on budget and they have exceeded my expectations in every way shape or form .I'm going to send them my Audi R8 for a twin turbo upgrade as well as my BMW X 5 M .I'm amazed at how fast my GTR is and the fact that I can drive it every day as if the car was bone stock .AMS is truly the best and I guarantee they smoke the rest !!!

The AMS ALPHA 9 package was everything I had hoped for and more. Working in the industry it was a breath of fresh air to work with a company that offers a package that not only meets my strict expectations for power but exceeded them. Fit and finish was some of the best I have ever seen, perfect fitment.”

As I’m probably the senior member and founding father of the GTR’s on the Island (Puerto Rico), I can attest to the dramatic evolution of you progressive menu of performance upgrades and the ultimate expression of maximizing the car’s capability. Certainly the turbos’ upgrade is the cornerstone of achieving such a great display of power across the entire RPM band without sacrificing drivability.  There’s no better way to attain for performance goals than the return on investment of your Alpha 9 products.  Truly satisfied !!!
