Pro Plus Racing coilovers have been designed from extensive research & development, engineering, testing, modification and experience from actual competition use. Pro Plus Racing coilovers enable both you and your team to fine tune your suspension setup for any form of track events and competitions. These coilovers feature independent adjustments for compression and rebound damping settings, as well as full length ride height adjustment.
This suspension system is ideal for automotive enthusiasts desiring excellent handling when they participate in frequent track events, and desire finely adjustable damping setups for absolute control. With an external reservoir, this system allows for increased oil capacity to dissipate heat more efficiently, which enables you to operate this product for a long period of time without failure. Individual damping will also improve performance & handling.
2-WAY EXTERNAL RESERVOIR
The 2-way Pro Plus Racing suspension system features an external reservoir, allowing you to adjust the rebound and compression damping separately. The canister comes with either a stainless braided hose or piggyback style reservoir depending on application.
3-WAY EXTERNAL RESERVOIR
The 3-way Pro Plus Racing suspension system offers independent low-speed and high-speed compression damping adjustments. It features 17 clicks of high-speed compression, 20 clicks of low-speed compression and 33 clicks of rebound damping adjustment. Drivers are able to fine tune the suspension to their desired damping rates for different road conditions and preferred suspension response. The canister comes with either a stainless braided hose or piggyback style reservoir depending on application.
With an external reservoir, this system provides extra oil capacity to dissipate heat more efficiently, which allows you to operate this product for long periods of time and improves performance & handling due to more stable variations in damping rates. The canister body is made of high grade steel or alloy aluminum material (depending on application) which can resist high gas pressures. The bottom of the canister is made of 7075 aircraft quality alloy, and is processed with an anodized surface treatment to prevent corrosion in the harsh conditions of motorsports.
PILLOWBALL UPPER MOUNTS w/ CAMBER PLATES
For suspension systems utilizing a MacPherson strut type, pillow ball mounts with adjustable camber plates (P/U *) are included in front (where applicable) to offer improved steering response and allow for camber adjustment.
For suspension systems utilizing a Double A-Arm strut type, this coilover kit comes standard with aluminum upper mounts (A/U). We also offer pillowball upper mounts (P/U) for Double A-Arm strut type as an upgrade for extra cost.
RADIAL BEARINGS
Any MacPherson style suspension is equipped with radial bearings at no additional charge. Radial bearings allow for more agile steering and prevents spring binding issues.
SHOCK BODY
The shock body is coated with an Electroplating treatment to prevent rust and corrosion in the harsh conditions of motorsports.
High quality components are adopted to ensure product durability and stability. Each application is test fit and completely road tested to guarantee perfect performance and comfort.
Please note that ALL of our coilovers are hand built and made to order. Please allow 2-3 weeks for delivery.
