Owners Nissan Sunny Often faced with a dilemma: keep the standard steel wheels or switch to more aesthetic and lightweight cast options. The problem is that the factory bolt pattern (PCD) on many budget models of the Japanese automaker has specific parameters that do not coincide with mass offers on the aftermarket discs. For 14-radius models, the choice of original cast wheels can be extremely limited, which forces car owners to look for alternative ways of modernization.
Process disc drilling is not just a mechanical expansion of holes, but a complex engineering task that requires precision down to fractions of a millimeter. An error in the calculations can lead to wheel runout, destruction of the hub bearings, or even the wheel coming off while driving. In this material we will look in detail at how to adapt disks to Nissan Sunny, what parameters need to be taken into account and why saving on professional equipment is unacceptable.
Many people try to find ready-made wheels with the desired bolt pattern, but the used auto parts market does not always offer suitable options. If you find beautiful 14-inch wheels, but they PCD differs from the standard one (for example, 4x100 instead of 4x114.3 or vice versa), you have two options: look for rare original wheels or order a re-drilling service. The latter option often turns out to be more profitable and allows you to install disks of any brand, if the technical requirements are met.
Bolt pattern parameters and compatibility for Nissan Sunny
Before you begin any manipulations, you need to know exactly the factory parameters of your car. For Nissan Sunny with 14-inch wheels the standard bolt pattern is most often 4x114.3, however, there are modifications with the parameter 4x100. An error in determining this parameter is fatal: the disk simply will not fit on the hub, or the bolts will be tightened askew.
In addition to the number of bolts and circle diameter (PCD), center bore diameter (DIA) and wheel offset (ET) are critical. Central hole should ensure a tight fit of the disc on the hub. If the hole is larger, be sure to use centering rings. If it is less, the disk will not fit on the hub, and it will have to be bored, which also requires precision.
- 🔧 Check vehicle documentation or door frame sticker for accurate PCD.
- 🔧 Make sure that the diameter of the central hole is not less than the standard one (usually 60.1 mm or 66.1 mm).
- 🔧 Measure the offset (ET) so that the disc does not touch the arches or suspension elements when turning the steering wheel.
⚠️ Attention! If you plan to re-drill a 4x100 to 4x114.3 disc, make sure that the thickness of the disc (stiffener) allows this. On some thin alloy wheels, the distance between the old and new holes may not be sufficient to securely hold the bolts.
Technical requirements for the re-drilling process
Disc drilling is the process of removing metal and creating new bolt holes. The quality of this work directly affects safety. You can’t just take a drill and drill holes by eye. It is necessary to use a specialized machine with CNC, which guarantees the ideal geometry of the new holes.
The key is to keep the disc balanced. If drilling is done incorrectly, the center of mass of the wheel shifts, causing severe vibration at speed. In addition, the shape and taper of the bolt holes must strictly correspond to the shape of the threads and heads of the bolts (or nuts). Usage scans instead of drills allows you to get a more accurate result.
- 🛠 Use only professional machines with high positioning accuracy.
- 🛠 New holes must have the correct taper for the bolt seat (usually 60 degrees).
- 🛠 Old holes need to be either welded or covered if they fall into the load zone, but most often they are left as is if it is safe to do so.

Step-by-step instructions for upgrading disks
The process of adapting the disk to Nissan Sunny includes several stages, each of which requires careful preparation. First of all, the disk must be dismantled and cleaned of dirt and rust. New holes are then marked using a marking template or machine.
After marking, the drilling process begins. It is important to observe cutting conditions so as not to overheat the metal, which can lead to its deformation or loss of strength. After receiving new holes, they need to be processed countersink to remove burrs and ensure a tight fit of the bolts.
☑️ Preparation for re-drilling
The final stage is balancing. Even a perfectly drilled disc can be unbalanced due to uneven metal removal. Therefore, after work, the disk is necessarily sent to a balancing machine, where it is selected weights to compensate for deviations.
⚠️ Attention! Never try to drill a disc yourself in a garage without a special drill bit. Even a minimal deviation of 1-2 mm will cause the wheel to “beat” and the bolts to quickly unscrew due to vibration.
Selection of fasteners and additional elements
When changing the bolt pattern, it is often necessary to replace the standard bolts. Standard bolts may not be the correct length or taper shape. For Nissan Sunny it is important to select fasteners with the correct thread pitch, which is usually M12x1.25. Using the wrong bolts may strip the threads or prevent the wheel from being tightened to the correct torque.
If the diameter of the center hole of the new disc is larger than the vehicle hub, it is necessary to use centering rings (adapters). They are made of durable plastic or aluminum and are inserted into the disc hole, ensuring perfect alignment. Without them, the load on the bolts will be uneven, which is dangerous under extreme loads.
- 🔩 Select bolts with the correct length (usually 40-50 mm) and a 60 degree cone.
- 🔩 Use spacer rings if the difference in hole diameter DIA is more than 1mm.
- 🔩 Do not use cheap bolts with low strength grade 8.8 or lower.
What happens if you use the wrong bolts?
If you use bolts with the wrong taper angle or too short a length, the wheel will not seat tightly to the hub. This will place all the stress on the bolt threads, which will quickly break or break out, especially when braking or cornering.
Table of parameters for popular disk sizes
Below is a summary table that will help you navigate the disk parameters that are often encountered during upgrades Nissan Sunny. Please note that data may vary depending on the year of manufacture and specific vehicle equipment.
| Parameter | Value for Sunny (standard) | Common alternative (for re-drilling) | Note |
|---|---|---|---|
| PCD (bolt pattern) | 4x114.3 | 4x100 | Requires re-drilling or spacers |
| DIA (hole) | 60.1 mm | 66.1 mm / 72.6 mm | Be sure to use centering rings |
| ET (departure) | 35-45 mm | 30-50 mm | Too much overhang may interfere with the arch |
| carving | M12x1.25 | M12x1.25 | The thread pitch must match |
It is important to understand that re-drilling a disk for a Nissan Sunny requires strict adherence to tolerances on thread pitch and taper of bolt holes. Even minor deviations can cause an accident. If you are not confident in your skills, it is better to entrust this work to specialized services that have experience working with Japanese cars.
Security and legal aspects
After drilling the disks, you must make sure that the wheels are installed correctly. Check the tightening torque of the bolts with a torque wrench. For passenger cars Nissan this parameter is usually about 100-110 Nm. Undertightened bolts can unscrew, and overtightened bolts can strip the threads.
From a legal point of view, changes to the design of a car (including non-standard wheels) require approval from the traffic police. However, if the discs have manufacturer approvals and meet the parameters Nissan Sunny (even if they were re-drilled by professionals), this is often interpreted as a replacement of consumables. However, it is recommended to consult with lawyers or the technical department of the traffic police before registering changes.
- 🚗 Regularly check the tightening of the bolts after the first 1000 km of mileage on new rims.
- 🚗 Avoid using bolts with damaged threads or rust.
- 🚗 When undergoing technical inspection, be prepared to explain the nature of the design changes.
After installing re-drilled wheels, be sure to perform a wheel alignment, since changing the offset or geometry of the wheels can affect wheel alignment and tire wear.
High-quality re-drilling of disks is impossible without professional equipment and accurate calculations. Saving at this stage can cost you life and health.
FAQ: Frequently asked questions about drilling discs
Is it possible to re-drill a disc from 4x100 to 4x114.3 without losing strength?
Yes, this is possible if the disk has sufficient metal thickness in the area of the bolt holes. Professionals use CNC machines that minimize material removal. However, if the disc is too thin or old, the strength may be reduced and it may be better to look for another option.
Do I need to use centering rings when re-drilling?
If the new disk has a central hole (DIA) larger than the standard one (60.1 mm), then rings are required. They ensure the wheel is centered relative to the hub. Without them, the entire load will fall on the bolts, which is unacceptable.
How to check the quality of the work performed?
After installing the wheel, carry out a visual inspection: the disk should stand without play. When driving at low speed there should be no wobble in the steering wheel. Also check the tightening torque of the bolts with a torque wrench after 50-100 km.
How much does the disk re-drilling service cost?
The price depends on the region and complexity of the work. Typically the cost varies from 1500 to 3000 rubles per set (4 discs). This amount often includes balancing and alignment, but check with the service center for details.
Can spacers be used instead of re-drilling?
Spacers are an alternative option, but they increase wheel offset (ET), which can cause wheel arches to catch. In addition, spacers create additional stress on the wheel bearings. Re-drilling is considered a more reliable and aesthetic solution.
