2. What are BONOSS Titanium wheel bolts on BMW E31 cars?

They have been fully TÜV ISO standard certificated: Tensile Strength≥1,100Mpa, Ultimate Tensile Load≥138,800N, Proof Load≥104,000N, and Hardness (Vickers)≥347. Each BONOSS Titanium wheel bolt weight is about 62g, and the whole set will save several pounds of weight. In addition, the precision of BONOSS Titanium locking wheel bolts have reached 0.02mm. High-precision stud conversion provides high surface integrity, stability, and reliability, and ensures a smooth installation experience.
3. How much weight of BONOSS BMW E31 Titanium wheel lock bolts?
Each BONOSS BMW E31 Titanium wheel bolt’s net weight is about 62g, and a set of BONOSS Titanium bolts’ weight is about 1240g. Compared with most OEM steel bolts, in the same length, thread, and seat type, the stock bolts’ weight is over 1840g. A set of Titanium wheel bolts can reduce the unsprung weight by about 600g. With the weight savings, you will get better handling. A lighter spring weight can reduce fuel consumption and vehicle loss, and effectively improve driving performance. A set of Titanium wheel bolts is absolutely a perfect option for racing, performance cars. BONOSS BMW E31 wheel bolts take safety, dependability, and style to the next level.
4. What types of Titanium wheel bolts do I need?
BONOSS BMW E31 Titanium wheel bolts are designed with floating seats. The floating seats are replaceable which allows for a perfect fit on any wheel. They are mainly available in two options depending on lug bolt size: conical seat and ball seat (R13 or R14). If you plan to keep the stock wheels, you need wheel bolts with the same seat type as the stock ones. If you intend to run aftermarket wheels, then both radius and conical seats are possible. Since the floating seats are not fixed, they can effectively prevent your beautiful wheels from being scratched by the bolts.
5. What do Heptagon locking wheel bolts mean?
As the name states, the Heptagon locking wheel bolts have unique Heptagon (7-side) shape heads, which make it hard to be stolen due to the irregular shape. To further improve the security, each heptagon Titanium wheel bolt is also a wheel lock. This means you get 20 wheel locks in a heptagon Titanium wheel bolts kit. Like other locking wheel bolts, this type of bolt requires a special heptagon socket for installation and removal. Even if the thieves have a full set of socket wrenches, they won’t have the unique seven-sided socket to fit. This effectively decreases the stolen risk of your wheels. For more details, check on Are locking wheel bolts worth it.
6. What are the advantages of BMW E31 Ti-6Al-4V wheel bolts?
Titanium wheel bolts are valued because of their high tensile strength-to-weight ratio. In simple words, for the same sizes, Titanium wheel bolts are much lighter than steel ones. Many racing enthusiasts will use Titanium wheel bolts for reducing vehicle weight. Less unsprung weight makes your car faster, decreases fuel consumption, and improves engine efficiency. Besides, Titanium maintains its strength at elevated temperatures. Even at extreme temperatures up to 400 to 500°C, they maintain great performance. That’s primarily why it is used in the aerospace field.
7. Will the BMW E31 Titanium wheel bolts come loose?
If a wheel bolt breaks due to corrosion, it may gradually loosen. Titanium wheel bolts feature extraordinary corrosion resistance. A thin oxide (TiO2, titania) layer spontaneously forms cover on the surface to protect them against rust or corrosion. Besides, BONOSS Titanium wheel bolts apply an excellent hard anodizing process. This process provides the surface with better abrasion resistance, flame resistance, and smoother and harder finish protection than regular anodizing plating. This means anodizing Titanium wheel bolts are not easy to corrode or oxidate which makes them safely work for long-term use.
8. Do I need new BMW E31 wheel bolts for new wheels?
Since aftermarket wheels are often designed by different manufacturers, there are different lug seats from the stock wheels. BONOSS Titanium wheel bolts are designed with floating seats. The floating seats are replaceable which allows for a perfect fit on any wheel. They are mainly available in two options depending on lug bolt size: conical seat and ball seat (R13 or R14). Besides, the separate design eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between the vehicle hub and wheels while driving. Since the floating seats are not fixed, they can effectively prevent your beautiful wheels from being scratched by the bolts. For more details, check on When should I replace wheel bolts.
9. How long are BMW E31 Titanium locking wheel bolts?
Getting the length of BMW E31 wheel bolts right is critical with regard to safe wheel installation. For OEM wheels, it is recommended to use the same thread length as the stock bolts. For aftermarket wheels or second-hand wheels, you would probably need a little longer wheel bolts to fit. If you install 10mm spacers, simply add up 10mm to the stock bolt length, the result value is the length of the extended bolts. (OEM bolt length + spacer thickness = extended wheel bolt length). BONOSS offers a full line of Titanium wheel bolts to suit your new wheels or wheel spacers, lengths from 27mm to 75mm.
