Hi all, I am new to this, so here it goes. I have an Astra H Turbo SRI and im looking to start modifying it, I have a Green Cotton panel filter and a VXR intake pipe installed recently but where do i go next before an eventual remap? Was thinking Courtaney silicone Hose pipe kit and either Eibach Pro-Kit or Sportline Springs, but which do i go for!!!???
Help appreciated and thanks!!!
