How High Is A Nissan Gt R

Alright, gearheads, let's dive deep into the vertical dimension of a legend: the Nissan GT-R. Specifically, we're talking about its overall height, why knowing it matters, and what factors influence it. Think of this as a deep dive, like when you're swapping out those coil-overs and need to know if your aftermarket suspension is actually lowering the car as much as you thought. We have the full technical diagram available for download, which we'll mention later, but for now, let's build a solid understanding.
Purpose: Why Height Matters
Why even bother knowing the exact height of a Nissan GT-R? Seems like a simple measurement, right? Wrong! Understanding the GT-R's height is crucial for several reasons:
- Clearance: Avoiding scraping that beautiful front splitter on speed bumps or steep driveways is paramount. Knowing your height, *especially* after modifications, helps you plan your routes and avoid embarrassing (and expensive) mishaps.
- Fitment: Does it fit in your garage? Sounds obvious, but trust me, many modifications can subtly alter the height. You want to be sure you can actually park your prized possession where it belongs.
- Transport: If you're planning on transporting your GT-R on a trailer or in an enclosed carrier, knowing the height is essential to ensure proper loading and securing.
- Aerodynamics: While the overall height directly isn't going to show you aerodynamics, knowing it can help you to see how much of a profile you are presenting, when you start to consider the length and width of your GT-R.
- Suspension Tuning: When adjusting coil-overs or air suspension, knowing the stock height provides a baseline for adjustments. You can accurately measure how much you've lowered or raised the car.
Key Specs and Main Parts Influencing Height
The official, stock height of a Nissan GT-R varies slightly depending on the model year. However, the generally accepted figure is around 1370mm (53.9 inches). Keep in mind that this is the height at the highest point of the roof, not necessarily the spoiler or antenna.
Several key components influence the overall height:
- Suspension: This is the biggest variable. Aftermarket coil-overs, air suspension, or even just worn-out stock shocks and springs can drastically alter ride height and, therefore, overall height.
- Tires: Changing tire sizes affects the overall rolling diameter, subtly raising or lowering the car. A taller sidewall will increase the height, while a shorter sidewall will decrease it.
- Wheels: While the wheel diameter itself doesn't change the overall height, the offset can affect how the suspension sits and, consequently, the height. Aggressive offsets might require adjustments to maintain proper clearance and avoid rubbing, potentially influencing the ride height.
- Body Kits: Front splitters, side skirts, and rear spoilers can significantly alter the perceived height, even if they don't directly affect the chassis height. A low-hanging front splitter will dramatically reduce your ground clearance, making the effective height a bigger concern.
- Factory Options: Different trim levels or optional packages may include slightly different suspension components, potentially leading to minor variations in height.
Decoding the Diagram: Symbols and Conventions
The technical diagram we have available is a detailed schematic showing all the crucial dimensions of the GT-R. Here’s a breakdown of common symbols and conventions you might encounter:
- Solid Lines: Represent visible outlines and edges of the car.
- Dashed Lines: Indicate hidden features or internal components. In the context of height, these might show the original design height versus the measured height after modification.
- Dimension Lines: Lines with arrows at both ends, indicating the measurement point and value. These are crucial for identifying the overall height and the height at specific points (e.g., the roof, the spoiler).
- Center Lines: Thin, dashed lines with alternating long and short dashes, indicating the center axis of the vehicle.
- Hatching: Used to denote cross-sectional areas or filled-in regions. This is less relevant for height measurements but might be present in diagrams detailing suspension components.
- Tolerance Symbols: Symbols like ± followed by a number indicate the acceptable variation from the specified dimension. Pay close attention to these, as they highlight the manufacturing tolerances.
- Abbreviations: Expect to see common abbreviations like "OAL" (Overall Length), "OAW" (Overall Width), and "OAH" (Overall Height).
- Units: Always pay attention to the units! Diagrams may use millimeters (mm), inches (in), or both. Double-check to avoid costly errors.
How It Works: The Geometry of Height
Determining the GT-R's height is essentially a matter of basic geometry. The overall height is the vertical distance from the lowest point of the car (usually the bottom of the tires) to the highest point (usually the roof or antenna). However, when troubleshooting or modifying the suspension, you'll need to understand how different components contribute to this overall measurement.
For example, let's say you install coil-overs. The coil-over's advertised lowering amount might not translate directly to the actual change in overall height. The following factors come into play:
- Spring Rate: A stiffer spring might result in a slightly higher ride height than a softer spring, even with the same preload setting.
- Preload: Adjusting the preload on the coil-overs affects the spring compression and, consequently, the ride height.
- Damper Settings: While dampers don't directly change ride height, they influence how the suspension settles and reacts to weight, potentially affecting the static height.
Therefore, accurately measuring the height at various points (e.g., fender arches, rocker panels) is crucial for fine-tuning your suspension setup.
Real-World Use: Basic Troubleshooting Tips
Here are some practical troubleshooting tips related to GT-R height issues:
- Uneven Ride Height: If one side of the car is noticeably lower than the other, suspect a worn or damaged suspension component, uneven tire pressure, or a bent chassis.
- Scraping: If you're constantly scraping the front splitter, consider raising the front ride height slightly, installing a skid plate, or modifying your driving habits (e.g., approaching obstacles at an angle).
- Difficulty Fitting in Garage: If you're suddenly having trouble fitting the GT-R in your garage after modifications, double-check the overall height and compare it to the garage door opening height. Also, check for obstructions like antennas or spoilers that might be interfering.
- Suspension Noises: Unusual clunking or squeaking sounds from the suspension often indicate worn-out bushings, ball joints, or shocks, which can affect ride height and handling.
- Alignment Issues: Significant changes to ride height will almost always require a wheel alignment to ensure proper handling and tire wear.
Safety: Risky Components
Working on the suspension system can be inherently dangerous. Here are some key safety considerations:
- Spring Compression: Coil springs store a tremendous amount of energy. Never attempt to disassemble a coil-over without using a proper spring compressor. Improper handling can result in serious injury or death.
- Lifting the Car: Always use jack stands to support the car after lifting it with a jack. Never work under a car supported only by a jack.
- Brake Lines: Be extremely careful when working near brake lines. Damage to a brake line can result in sudden brake failure.
- ABS Sensors: Avoid damaging the ABS sensors while working on the suspension. These sensors are crucial for the proper functioning of the anti-lock braking system.
- Torque Specifications: Always use a torque wrench and follow the manufacturer's torque specifications when tightening suspension components. Over- or under-tightening can lead to component failure.
We've got the full detailed technical diagram mentioned earlier, which can really help you visualize all these components. It’s a downloadable file, so you can have it right at your fingertips when you're wrenching. Use it to your advantage, double-check your measurements, and always prioritize safety. Happy wrenching!
