We have provided our products with many cars and received feedback from the distributors and customers. The following feedback was from a BMW 3 Series F30 customer, he chose a kit of BONOSS Forged Grade 12.9 Shell Type Lock Bolts. According to the data of BMW 320 F30, we collected before, front 27mm (1 inch) rear 27mm (1 inch), PCD 5*120, CB 72.5, conical seat bolts M14*1.25, we recommended installing 28mm’s product.

What does Shell Type Lock Bolt Kit do?

The product was named by BONOSS and this latest product is welcomed by many customers, short type and long type can be selected by customers, the product upgrades the appearance of bolt, match the bolt with a 7075-T6 material shell, that is the reason why BONOSS name it “Shell Type”. The shell has two functions. First, protect the wheel bolts from debris and water corrosion, extend the service life of wheel bolts. On the other hand, the trend of modding our unique cars is a part of car culture. We hope every car is special for every driver, even the detail of a piece of the bolt.

BMW 3 Series F30: Handling reliability & Performance

BMW F30 is a great success due to its fun, sporty chassis. Many people still chase a BMW F30 for achieving a driving scene that dream of, and other brands also did that as a car standard. Before we talk about F30, we need to know F30 is a sedan, F31 is a touring/wagon, and F34 is Gran Turismo(GT). We are focusing on US models, though there are some cars that are long-wheelbase versions of the F30 sedan. BMW’s beloved inline 6 engines remain. Most importantly, a lot of that weight is decreased from the front axle. This helps make the F30 320 a well balanced, nimble car. While we enter the 3 series level, 320 is welcomed by many customers. Sports car and lighter weight make it into a driving flexible car. The modification space of F30 is large. This F30 is very attractive because of its appearance, Pikachu stickers, and showy wheel bolts.


Obviously, here is the difference after installing the shell type lock bolt kits, these are short ones and it will be showier if it installed the long shell bolts. From the contrast, the wheel being more fuller and classical colors red and blue is a perfect match.

(Pay attention: the reason why the customer chooses conical seat bolts is according to the wheels, the bolts seat type should match the wheel seat type.)
