2009 Nissan GT-R Ownership Myths Dispelled
There’s no speed limiter, the tires won’t wear out in 3000 miles, and Nissan even picks up some of the service costs.

You’ve likely already read the various rumors flying around the Internet about the GT-R’s steep ownership costs; that it has a speed limiter unless you’re at a Nissan-approved track; and that tires can only be replaced four at a time. We heard these things, too, courtesy of a tire supplier to GT-R, so we called up Nissan and got to the bottom of it. Most of the gloom-and-doom hype is unfounded. See below for our questions and Nissan’s responses.

Rumor 1: Nissan’s GPS will only allow full-speed operation in the U.S. at Nissan-approved tracks.

There is no speed limiter on the U.S. spec GT-R unless you count the rev limiter.

Rumor 2: Once a vehicle has been run an approved track, it must be subjected to a post-track safety inspection at a Nissan dealer (brake fluid, suspension, tires, drivetrain, other checks), at an estimated cost of $1,000. Otherwise the warranty is voided.

It is a very good idea to inspect a car of the GT-R’s potential after spending time on a track to verify that everything is still within specifications and not worn. We are investigating offering this type of post-track inspection service to GT-R owners in the U.S. in order to provide the type of customer service some GT-R owners will want.

Rumor 3: The vehicle is set up from the factory with suspension settings for track use, with very high negative camber in the front and substantial toe-in at the rear. If the car is driven on the street with the factory settings the tires will only last 3000–5000 miles, and inner tire wear in the front will be substantial within 1000 miles. The settings may be changed from factory settings for street use prior to delivery, however.

The normal front camber setting is 1 degree 36 minutes negative. This can range plus or minus 10 minutes so if a customer wants to maximize tire wear they can request less negative camber. The rear toe setting is 1.7 mm total toe-in. While these settings are more aggressive than most cars, they are not extreme. The car provides amazing performance and you wouldn’t expect it to behave like a typical car. Based on our testing we anticipate tire life to range from 12,000–15,000 miles in typical street driving. Of course, track usage will definitely diminish tire life.

Rumor 4: The brakes are some type of ceramic composite, and a brake job will cost upwards of $3000.

The GT-R brakes use conventional materials. The brakes have full-floating two-piece rotors. The outer rotor is cast iron and the hub or hat is aluminum. The pads are also conventional materials. They are large Brembos—15-inch rotors front and rear, six-piston calipers front and four-piston rear—so they won’t be inexpensive, but they provide phenomenal stopping performance. We don’t expect a 500-hp engine to cost the same as a 300-hp engine, so we wouldn’t expect 500–hp brakes to cost the same as 300-hp brakes. We don’t have final pricing on the parts yet so we can’t say for certain how much they’ll cost.

Rumor 5: The OE run-flat, vehicle-specific Bridgestone tires, once dismounted, must be discarded. We have not heard if the same requirement applies to the OE Dunlop tires, but that is a reasonable assumption. One of the explanations for this that we’ve heard is that the rims have raised bumps in them at the beads to keep the tire from turning on the rim under acceleration.

Our recommendation is that the GT-R tires not be remounted regardless of brand. The knurled beads do help keep the tires from rotating on the wheels under hard acceleration, but the knurling is primarily there as part of the run-flat system to help keep the tire on the rim in the event of a flat. Remounting the tires is not recommended because of the stretching and flexing necessary to remount the run flat tires on the wheels.

Rumor 6: If any tire on the all-wheel-drive GT-R needs to be replaced, such as for a road hazard, Nissan requires that all four tires be replaced; otherwise the drivetrain warranty is voided.

Because the GT-R is all-wheel drive, matching tire circumference is critical to the performance of the system. We will be providing guidelines to help determine if only one tire can be replaced or if the entire set should be replaced. If the undamaged tires are showing limited wear, it may be possible to replace only the damaged tire. These guidelines have not been finalized yet.

Rumor 7: Estimated annual service costs for the GT-R are $10,000–$15,000.

Service costs for the GT-R will vary greatly depending on usage so we do not have an estimate of annual service costs. But these estimates seem very high, however. There are a series of Performance Optimization Services (POS) required for the GT-R. The Performance Optimization Services (POS) are inspections and adjustments (if needed) of three major vehicle performance systems: Engine settings, transmission settings, and wheel alignment. These services are required to keep the car functioning at optimal performance and are done free of charge for the first 36 months. These services are necessary to keep the warranty in full effect for these systems.

The first Performance Optimization Service is performed at 1000 miles. The subsequent services are performed at 12, 24, and 36 months. Additionally, it is recommended these services be continued annually beyond the first three years, but they will be at customer expense.

While this is not a free maintenance program since it doesn’t include oil changes or other maintenance, it should make keep the ownership costs pretty reasonable for such a high-performance car.


Rumor 8: Nissan is struggling with finalizing the full-disclosure form that customers are required to read and sign prior to taking delivery.

We are still finalizing the delivery materials but I wouldn’t characterize it as struggling. The GT-R is unique in offering incredible performance to a very broad range of customers so we want to make sure we provide as much information as possible to the customer at delivery to make sure they have a great ownership experience.

Rumor 9: Only the dealer principal is allowed to sell this vehicle. Salespeople are not allowed to sell it, related to the risk that the salesperson may not properly inform the customer about the details of the full-disclosure documentation.

This is a customer-service issue not a disclosure issue. When choosing to become Certified GT-R dealer, the dealers agreed to designate the dealer principal, executive manager, or general manager as the dedicated GT-R sales representative. Since the GT-R will attract a unique customer, Nissan decided a dealership executive would be best positioned to present the vehicle and facilitate the transaction most effectively with potential customers. The ownership experience will be critical to the success of the GT-R, and this requirement involves a dealership executive in a face-to-face relationship with the customer. This should be a positive step for customer satisfaction.

good info, thanks for the find!

I have to laugh at the Performance Optimization Services acronym (POS). lol I can already hear the Vette guys using it in its well known form.

They didn't actually answer Myth #2...

A lot of us might put 3000 miles on our cars in 3 years... How many of these "Performance Optimization Service" visits do they expect us to make with low mileage? Even if we only put 6000 miles a year how many visits? I'd like to see some sort of exception for this specific service that is essentially mileage based and nothing else. I'd hate to only be able to cash in on 2 visits and have to pay for the rest simply because I didn't drive it enough.. I wonder how much they will cost when not under warranty...?

Not real happy about these scenario's. I'm used to getting 40,000 miles out of a set of tires. Holy sh*t, I'm gonna be paying big bucks just to keep rubber on this puppy. I never expected this new_cussing.gif

If you (or anyone else reading this) wants to give up your MSRP allocation to me, let me know...

And doesn't this sorta show that dealers are going to be making a killing in their service department for this car, and that they really don't need to charge a markup to regain their initial invesment

rumor = fact = mystery = rumor = fact #21; Article VIII:

2009 GT-R owner's manual; from NNA:

"Any repositioning of the factory seat settings will void warranty unless the valve stems are inspected under full load; any tampering with the seat adjustments will be detected by a computer sensor under the driver's side intercooler housing and will void warranty unless the valve stems are repositioned while car is in transit. Any shipping of the GT-R to an undisclosed location either by a third-party service or under the driver's own guidance will void the factory warranty."

Nice find, thanks Chuck.

This wheel issue is concerning, but maybe not. I have never owned a 4WD sports car so I do not know how sensitive it will be to changes.

Interesting seeing their take on the tire size/circumference etc. The set I am choosing to run on this car has a 0.51% diameter difference and 0.51% circumference difference in the front (my tire choice slightly smaller in both measurements), and a 0.22% diameter difference and circumference difference in the rear (my tire choice slightly larger in both measurements).

Stock GT-R sizes show a 0.51% diameter and circumference difference front to rear with the rears being slightly larger in both.

My tire choice shows a 1.22% diameter difference and circumference difference front to rear with the rears being slightly larger that the fronts.

Stock fronts 245mm section, my choice 275mm section. Stock rears 285mm section, my choice 335mm section.

Any of you 4WD experts see anything off with my intentions, how close does it have to be?

As far as the actual mileage the stock tires will run on the street, I have never succeeded in getting over 15,000 street miles on my sport cars, so I'm OK with this.

Umm, I was expecting WORSE wear for the GT-R's tires, My pops Evo went through the Factory Advans in about 8000 mi. So I was expecting 2-3000 miles at most for the factoy Bridgestones.

No, I am just fine with the mileage estimates. I am only concerned with the way they keep stressing changes to the wheels. Not re-mounting tires, and now, they are talking about the possibility that if you get a flat on one tire, you may have to swap out other tires to keep within some tolerance for the circumference of the tire. How sensitive is this car. Going to be interesting to see what these guidelines are but what they are telling you here, is you get a flat at say 5,000 miles on one tire, you could be replacing all four of those run flats.

Yeah the tire thing is absurd. If true, blame the engineers. This isn't a spaceship. The car should have been designed with the flat tire scenario in mind, and if they couldn't address it properly go back to the drawing board, or hire some Germans...

With the junk German car companies produce, they should have hired some Japanese 30 years ago.

my evo's advans lasted over 12k miles and 3 long track days.... I'm havent concerns on this.... I'm glad they said some of these ownership costs are way overstimated....

And I'll stay with stock tires maybe after reading enough on them, switch to the dunlops maybe

I still want to have a lawyer review the "sale / ownership terms" before delivery.

I hope this isn't one of the cases like oil price.. "sell into your life with low cost first.. and proceed to suck out all the money in your pocket later" thingy..

The older ATTESA system is a little sensitive. You don't want to mess with the tire heights too much. If you do, you get a fault code. I have had the ATTESA lights come on in an R33 with worn rear tires.

The actual spec is 0.2 inch difference in height before it will throw a code for the older system. Same/ similar to a FX35/45 system.

ATTESA information

On the tires, you don't get your cake and get to eat it to. High performance tires don't last 40,000 miles. If you are going from something with 40,000 mile tires to a GT-R, you might have picked the wrong car to buy.

Is this side to side (left side /right side correspondingly for front or rear) or is it front to back, ie, front tires have to be within 0.2 inch of rear tires etc.

The stock GT-R tire size is 0.14 inch diameter difference, front to rear. The stock GT-R tire size circumference difference is 0.44 inch front to rear.

My tire size choice is 0.34 inch diameter difference, front to rear. My tire size choice circumference difference is 1.07 inch front to rear.

I was told, the size I want to run will work. Now I wonder, will it really, or is it going to throw a fit about being out of tolerances.

I never tried side to side, but front to back of 0.2 is listed as causing a code in R32/R33/R34. The older cars ran the same size tire front and rear.

The new car has a staggered setup, so it might be able to figure it out, be a little looser on the tolerances. As a consumer though, not something you want to work out. I would rather have someone that has the ability to get it right figure that out, right or wrong.

The real answer is you will get to be the guinea pig for everyone else.
