Hi, Jason,
Well done on the pass. I really do like the royal blue colour.
I'm sorry that I missed your request for images of my IVA reflectors. I wouldn't have been much help as I had made a bumper type construction to hold the number plate / fog and reversing lights and was able to mount 2" diameter round reflectors on single instrument pods on the end of that. Jon has some smaller stick-on reflectors that are probably the neatest I have seen. Post IVA, I fitted Porsche 356 copy reflectors on mine which sit upright and proud of the bodywork on little posts and mimic items from the correct era.
I had a car trimmer wrap a 1" ratchet strap with red vinyl (that I got from Westfield) to give me non stretching door straps. They look stock and have worked without problems in temperatures up to 35 degrees.
I re-fabricated my door mirror mounts so that the bullet mirrors sit upright, rather than on their side. It was obvious to me that the passenger side item, if fitted on its side, would never angle in far enough to be anything other than an ornament! They now function as mirrors but will never match a modern car's field of view with such small glasses. I believe that Stephen H found some convex glasses for his which he says makes quite a difference. Trying these is on my "non-urgent" to do list.
I too struggle with noise. I passed the IVA with a smaller diameter link pipe containing an extra silencer, which I then encased with a 2" outer pipe. It still recorded 99dB(A) at the test. I have a new silencer to put on (as well as a second silencer that is already in a 2" link pipe) so I am hoping that this will bring it down sufficiently to be allowed to run at a track day at nearby Abingdon airfield - it currently tests at 101dB(A) on the original silencer and the organisers are unable to offer any leeway with their 100dB(A) at 3/4 maximum rpm - I declared 6,000rpm as maximum.
Good luck with your first run - I am sure you will enjoy it. I certainly did mine!
