On the sti bumper there is 3 small slots that the top of the winglet clips into. If you are fitting them to a wrx, cut the tabs off the top of the winglets and stick on with tigerseal or any windscreen glue, thats what i did to my wagon.
Got followed all the way from royston to stevenage in my GTR on the baldock bypass a few years ago by a green unmarked ford mondeo, i was going a little bit fast
MOT runs out Sat, not got a day off till weds & thurs next week so one morning will be used getting that sorted. I think a meet would be good, maybe get a few more herts owners interested?
I drive to watford each day to get to work, i go round the back of hitchin and into luton to get the M1, I see at least 3 every morning, A red hawkeye, a blue blobeye wagon, and a rb5.
