BMW 325i G20: Latest one

G20 steering is intuitive and predictable, the suspension is firm without roughness, throttle response is rewarding with acceleration. It’s surprising how the TU B46 4-cylinder engine performed like a 6-cylinder with an amount of horsepower and torque. The acceleration performance still manifests the pureblood from BMW. The cabin noise level is vastly improved. The stiffer chassis and improved torsional rigidity enabled it to accelerate through sharp turns with confidence.

This BMW 325i G20 mods:BONOSS Forged Lightweight Plus Wheel Spacers, BONOSS Forged Grade 12.9 Shell Type Lock Bolt Kits, BBS Wheels.

(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.)


Why choose BONOSS Wheel Spacers and Shell Type Lock Bolt Kits?

BONOSS Wheel Spacers compared with the previous product before the upgrade, the weight is reduced by about 20% on average, and the lightweight effect is more direct, it is designed with a special “disassembly slot”, easy to remove and install, improve work efficiency. The “knurling” design is used on the cylindrical surface of the wheel spacer, which can effectively increase the contact area with air and enhance the cooling effect. It uses a sealed design to prevent rainwater and debris from entering the wheel hub assembly.

Shell type lock bolt kit 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.

An awesome combination of them! Calculate the accurate length of wheel spacers and stock bolts, we need some extended bolts to match the length. Extended bolts can be various, normal grade 12.9 extended bolts, shell type lock bolt kits, stud conversion kits….etc. The generality of these products is extended. They need to satisfy the basic need of the customer which is safe enough for daily driving.
