are the RB320 springs just Prodrive springs painted black?
 

because i have prodrive springs and 18" wheels on my 06 (see my other thread) and the ride height looks the same... does anyone know?

what would be great is if any RB320 owner could measure the distance from the top of the tyre wall to wheel arch front and back and i will do the same so we can compare?

Yours looks like the Std Prodrive springs ride hieght the ride hieght on the RB320 looks to be a bit lower.

IIRC

Sti Prodrive springs are Pink and WRX Blue.

IIRC
The RB320 has not Prodrive Springs it has Bilstien struts and Eibach springs Fitted
