I been working on my car for the past couple weeks now, just fixing and upgrading small parts but my newest part that I need to save for is a coilover system. I have an 07 STi on stock suspension and I was wondering if the helper springs that come with the GR+Pro really make a difference compared to the flagship model GR+. I just dunno which model to get. If you guys could help me figure this out it would be awesome.

Thanks!

 

Ah yes... one of these threads again.

Have you asked yourself if you NEED coilovers? If yes, the Stance are a great set-up. If no, just go with lower springs.

 

depends on your application. the helper spring helps the main spring stay seated when it is fully unloaded. this is especially useful if you have short suspension travel. it means the suspension is still loaded and will function (better? or more linearly?) when it becomes sprung again.

 

Yeah, make sure you really need coilovers springs. I'm running 5Zigen R-Rated lowing springs on my Impreza and they work and look great.
