Sometimes standard is not too bad, given the amount of research manufacturers go through too get something that works under a wide variety of driving conditions
mudflaps will also help protect the rear doors - had them on my impreza, there was some pittting but more likely from gravel / tarmac thrown up from the road. Keep us posted on you choice
Yup this is an issue with keeping the lower panels in place, water sits there and rots the subframes. Fortunately it is a reasonably straightforward job to repair / repaint or replace the units
I had 18's on my Sti with no issues - the manual did say you would get some noise from the diff on occasion but I was never as extreme as you describe - what size are the tyres on your 17's?
depends which ones you have installed currently - I have LEDs in my Scoob and Vito - both have been in for quite a while so I would say stick with LEDs
Hi sorry - slightly confused by the TLA - are you saying your Intake Absolute Manifold Pressure is down to zero? If the car is still generating boost but the manifold pressure is zero there is a huge mismatch (or hole) somewhere between what the turbo is capable of holding and the engine needs.
The MAP sensor is a key player here but given the history I wouldn't know if it was calibrated prior to or during the session you had. We just have a snapshot of one thing happening and no view of the relationship to the rest of you motor so I just guessing - sorry
