BONOSS Forged Active Cooling Wheel Spacers 25mm for Subaru WRX STI 10th (2)

Effective performance upgrade! Yesterday, this Subaru WRX STI 10th installed BONOSS Forged Active Cooling Wheel Spacers, front/rear 25mm (1″), PCD 5×114.3, CB 56.1. Wheel spacers are a kind of aftermarket component of one purpose: relocating your wheels outwards from the vehicle hub. They’re a simple and inexpensive upgrade that provides many advantages to both street cars and off-road vehicles. By sandwiching between the assembly hub and wheel, they create a gap that sets the wheel away to an ideal distance. This increases the distance between the left and right wheels. A wider wheel track offers better traction, leading to more stability and better handling performance, that is why they are often used on many racing cars.

The Subaru WRX STI 10th is undoubtedly an excellent station wagon. It comes with a spacious, well-built, and comfortable cabin which gives the car a more enjoyable drive than other competitors. A turbocharged 2.5-liter flat-four engine is standard to make 305 horsepower. Although every data is good enough to use, many car enthusiasts still choose to upgrade the OEM parts for better performance. And, installing wheel spacers is one of the easiest and most cost-effective options to get low and wide as well as to get flush the fender flares. Properly filled wheel arches can really make your car look wonderful. (Thanks to the owner for providing these pics.)

Use High-quality Wheel Spacers

Quality is a crucial part of wheel spacers safety. This is why BONOSS only uses the highest quality materials. BONOSS wheel spacers are made of high-grade forged 6061-T6 billet aluminum alloy that is as strong as aviation aircraft. They are made with modern CNC machinery with an accuracy of 0.02mm tolerance, which offers an excellent surface quality and a smooth installation experience. Not just the spacers themselves, but the lug studs or extended bolts too. The wheel lugs apply a clamping force to secure the spacer and wheel to the vehicle hub. So, make sure you have equal or stronger lug studs or bolts than OEM studs or bolts that they can lock everything in the right place. The matching wheel studs of BONOSS wheel spacers applied high-strength JIS SCM440 steel material. They are ISO Standard Grade 12.9 approved (most OEM studs are grade 10.9), which showcase good ductility and high-temperature stress resistance, structural stability, wear-resistance, excellent toughness, impact resistance, and more advantages.

Dismounting Grooves Design for Effective Installation

Dismounting grooves means the small notches which are distributed on the corner of wheel spacers. It is designed to easily dismount the spacers, improving the user experience. Normally, it leaves a limited clearance between the axle plate and spacer, using a screwdriver can easily remove the spacers, simple and efficient. If there is no such groove, the spacer will snug the vehicle hub, by forces effect, it can be difficult to dismount. Even worse, you may destroy the spacers or axle hub. Furthermore, the grooves can act as an air collecting funnel, which is effectively increasing airflow, enhancing the heat dissipation effect.
