OK so today I got the spoiler fitted properly.
Started off with the reenforcement brackets my stepfather kindly made for me. Obviously they just needed to be metal and cut to fit. Him being an engineer means that they were cut, bevelled and countersunk with high precision. Shame they get hidden really.
The purpose of the cut out is so that they can be rotated into position. I just followed a guide on the shape from a poster on S2Ki.
Moving them into place was really easy, the curve of the boot lid and the internal ribbing held it in place which made it easier to install the bolts. I dropped a bolt down the ribbing. That was interesting..
Basically a 20 minute FAFF with a coat hanger to grab the bolt.
The biggest job was installing the torsion springs for the boot lid. Due to the extra weight of the spoiler, thicker springs are needed to ensure it doesn't slam down and the boot clicker still opens.
Honda sell a tool but I decided to have a go anyway using mole grips and a tyre lever. Neither worked and in the end I used a small claw hammer. Nasty job that was. Do not advise.
Only one journey done in the car with the spoiler on so I can't tell if it makes much of a difference.
However. There was a bunch of little lads giving me the thumbs up whilst I was at a junction.
That doesn't happen usually. I didn't see them thumbs upping any Clio's or Fiestas either so they must have liked the wing.
