Advanced Pro PlusCoilover Application

Yellow speed racing ADVANCED PRO PLUS is a 2-way coilover system with inverted mono tube dampers made for vehicles with MacPherson strut type only. The system allows you to adjust the rebound and compression damping separately. With an external reservoir, this system provides extra oil capacity to dissipate heat superiorly, which allows you to operate this product for long period and improves performance & handling due to more stable variations in damping rates during the vehicle high speed. The braided hose is utilized to connect the external reservoir through upper mounts; this is ideal to allow for variable mounting locations when the external reservoir is mounted (installers take a full responsibility for the mounting location of the external reservoir).

Yellow speed racing engineering team and a Japanese professional rally driver have been testing and modifying, and testing and modifying to ensure this new product will meet all performance and quality demands. Improvements in many aspects of testing have been made over 15 months; this product will bring you to a new level of racing spirits.





This series contains 3 types of suspension systems:    ● Circuit Race    ● Tarmac Rally    ● Gravel Rally




● for Circuit Race

  • spring rate range from 12kg to 20kg (depending on applications)
  • shock valving and spring rates are specifically made for Circuit Race use
  • setting ride height: -30mm ~ -40mm down from stock height (depending on applications)
  • lower bracket is designed for rigidity and strength (where applicable)
  • For suspension system with MacPherson strut type, the monotube inverted design is utilized to reduce the effect upon the damping oil and shock piston resulting from high temperature from the brake system.
  • The standard upper mount equipped with the kit is pillow ball upper mounts (where applicable), and 3D upper mounts which enable you to adjust CASTER and CAMBER are OPTIONAL for Circuit Race type for extra cost; however, 3D upper mounts are not available for all car models, please check the product availability with us before placing an order to make sure the item you would like to order is available.
  • The production lead time is about 12-14 business days.

3D upper mount ( camber & caster )

● for RALLY TARMAC

  • Spring rate range from 7kg to 13kg (depending on the applications)
  • Setting ride height: -10mm ~ -20mm down from stock height (depending on applications)
  • Lower bracket is designed for rigidity and strength (where applicable)
  • For suspension system with MacPherson strut type, monotube inverted design is utilized to reduce the effect upon the damping oil and shock piston resulting from high temperature from the brake system.
  • The standard upper mount equipped with the kit is pillow ball upper mount (where applicable). For some race regulations, we also offer R/U (hardened rubber upper mount) for customers to choose from.
  • The damping setting and spring rates are setup between Dynamic Pro Sport and Premium Competition types.
  • The production lead time is about 12-14 business days.

● for RALLY GRAVEL

  • spring rate range from 3kg to 7kg (depending on applications)
  • long shock travel (similar length to original ) (depending on applications)
  • setting ride height: +20 ~ +30mm up from stock height (depending on applications)
  • lower bracket is designed for rigidity and strength (where applicable)
  • For suspension system with MacPherson strut type, monotube inverted design is utilized to reduce the effect upon the damping oil and shock piston resulting from high temperature from the brake system.
  • The standard upper mount equipped with the kit is pillow ball upper mount (where applicable). For some race regulations, we also offer R/U (hardened rubber upper mount) for customers to choose from.
  • Front upper mount is made thicker by about 4mm (depending on applications).
  • The production lead time is about 12-14 business days.
