A couple of changes..
Had to give up getting alloy wheels this time around due to a poor return (as above), but it's still in the near future. Tyres however wouldn't wait, so I had 4x 215/55/zr17s thrown on this morning, of a cheap and I'm sure nasty brand (the name eludes me, but you get what you pay for with tyres). Not at all for performance but I refuse to put expensive rubber on wheels I plan to upgrade in a few months.
Also played around with the intake a bit further. I previously did the vacuum hose mod and noticed bugger all difference in intake noise. Today I removed the lower air intake piping, and made a PVC spacer to hold the flap in the upper intake path open - I'm not sure whether the vacuum hose mod does it anyway, but considering it's rest position is closed I'd rather hold it open.
The difference in intake noise now is HUGE. With any throttle under load it's got a really nice deep intake rumble.
