Whiteline Plus Polyurethane Front Strut Mount Bushing Kit

Your BC Racing Coilovers come with new bearings.

Fits all 04-06 GTO models.

Have collapsed strut mount bushings or looking for a better ride quality? 

WHITELINE PLUS is a range of progressive polyurethane suspension bushings and components. By 'progressive' we are referring to the polyurethane's ability to provide the quality ride of rubber at lower speeds and at higher speeds to become firmer, when under cornering pressure, for CHASSIS CONTROL and improved handling of your GTO.

Whiteline Plus Polyurethane Radius Rod Bushings

A critical service item for any Pontiac GTO, as the original fluid filled bushing fails prematurely causing shuddering under heavy braking and excess wheel movement. Whiteline Plus offers a perfect solution that induces a responsive braking vehicle and includes caster adjustment for precise handling

Whiteline Plus Radius Rod Bushings offer the following benefits:

●  Ease of fitment with limited tools and skill required

●  Positive caster angle retention under all driving and suspension load conditions.

●  Dramatic increase in steering response giving "crisp" handling, especially when optional wheel and tire packages are used.

●  Noticeable improvement in braking performance under all conditions.

●  Caster increases up to 15mm in positive direction (+2 degrees) and 3mm in the negative direction (-0.4 degrees)

BC Racing Coilovers

The BR model is perfect for street driving and occasional road course duty. With easily accessible adjustment knobs for fine tuning your compression/rebound and separately adjustable ride height, having a performance coilover system couldn't be any easier. You choose how low or high you want your vehicle, no preset ride height here, and our patented concave lower locking ring keeps it locked in. All the systems come with pillowball mounts to provide the most feedback possible from your suspension and to sharpen your steering response. BC's available front and rear camber plates also allow you to get the perfect alignment setup without compromise. All this while providing a strong, attractive looking coilover system.

The BR series coilovers use a large 46mm diameter piston in a 53mm diameter damper body to maximize oil capacity. As the damper unit operates, the oil within heats up. The viscosity of oil changes as its temperature varies which can lead to changes in the damping characteristic of the unit. BC Racing only use a very high quality oil which their coilovers but go that extra mile to maximize performance and build their BR ranger with a large 53mm diameter damper body. This increases the capacity of the unit which increases the volume of oil contained which in turn reduces the peak temperature and so significantly improves damper performance.

BR coilovers feature 30 way damping adjustment that combines both rebound and compression in one adjuster for simplicity and ease of use. This adjustable facility allows you to fine tune the vehicle to meet the relevant conditions.  

Damper units are black chromed steel to give superb durability even through the darkest of winters. The aluminum components (top mounts, locking collars etc) are anodized and the steel lower mounts go through an electrophoretic disposition process followed by powder coating. A random selection of steel components (brackets, dampers, screws etc) are put through a salt spray test once a month to check the quality of the protective processes and that anti corrosive properties are kept at the highest possible standard.

● Mono-tube shock design

Technical

● Coilovers use 46mm pistons and 53mm shock housings, the enlarged shock cartridges with specially designed pistons and rods provide a wide range of damping force.

● Valves are constructed of special spring steel, which outperforms stainless steels and produces longer valve life. Valve stacks use a patented deflective system to provide more precise control.

● Patented concave lower locking ring, to prevent unseating.

● Springs are made of SAE9254 high strength, durable steel. Compression tested at over 500,000 tires with less than 5% deformation.

● T6061 Aluminum utilized in spring locks and seats for high strength and lightweight.

● Iron lower brackets on MacPherson struts to ensure rigidity.

● Piston rods are constructed of highly polished steel to lengthen oil seal life and prevent leaking.

● High pressure inner rod guide seals ensure a perfect fit for consistent fade resistant damping and long shock life.

● 2 step coating process utilizing nickel and chromium plating to prevent corrosion.

● Newly developed lubricant oil in shock cartridges minimizes aeration and cavitation.

● An additional bearing beneath each pillowball mount provides the smoothest action and prolongs the lifetime of the pillowball itself.
