BC Racing BR Series Coilovers - Impreza STI (GRB) - RA Coilover Series:RA Our breakthrough injector design uses

Our breakthrough injector design uses unique Swirl Generator Technology that improves atomization to deliver faster inlet temp cooling and uses less fluid to maintain inlet air cooling

While flow of exhaust gases (transport delay) can affect deadtime

Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency

Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor

BC Racing BR Series Coilovers - Impreza STI (GRB) - RA Coilover Series:RA Our breakthrough injector design usesBC Racing are one of the largest suppliers of aftermarket coilovers, catering for a huge range of makes and models, in many cases with multiple kits for each vehicle to suit a range of uses and budgets. BR Series is BC's entry level coilover, utilising a large 46mm diameter piston in a 53mm diameter damper body for maximum oil capacity. By using combining this increased capacity with high quality oils within their coilovers, temperature fluctuations
