Thanks for all the feedback folks.
Think i might drop the rear ones down to the next set of holes, they are sitting a bit high. The front ones look braw though
Just checked and my jack brace thingy is under that board too D'oh!! That could have saved me about 10 minutes and left the skin on my knuckles!!
Ordered a pair of "airdam skirts" (Subaru's words, not mine) which are the front bumper extensions that are standard on an STI. Got them today (£130 inc. SIDC discount, VAT & postage), but Subaru only do them in STi-colours, so i got mine in white. They are in getting painted just now, hopefully get them back on Monday night.
Karl - i got the wee roof spoiler from Revolution. I think it was £119.99, but they only get their supplier (Lester in Italy) to make them when they have orders, so they take about 5-6 weeks to arrive.
