A question for the gentlemen of the U ...
Mirrors for the GTR. Do they work properly at UK speeds, or do they vibrate? Is the visibility over and around the rear wing acceptable; for exammple on a busy motorway.
Having seen the rather appealing idea of Can Am mirrors on a GTR, is it more practical?
Also, regarding double din AV. Are the poitioning tolerances in the passanger side very tight. I am thinking of getting a nav unit with possibly a second smaller monitor on the front roll bar to act as a rear view mirror (with suitable camera).
Do you have any recommendations for aerials (internal/roof mounted)
Your thoughts on both subjects are greatly appreciated.
To answer your questions in turn:
Yes, mirrors work fine in standard GTR posiition, or can-am style, even at speeed. I have can-am style on my GTR, lowered 80mm since IVA. See pic. What you need to be concerned with is the field of view for IVA. Can am style mirrors on a GTR work fine for IVA at standard height and arguably give a better field of view as they are slightly further out. They also are not impacted by the wing position, being a bit lower that standard GTR mirrors. When I went to IVA, I don't beleive anyone had fitted Can-am mirrors on a GTR before, so I left them standard height, only lowering them subsequently for purely aesthetic reasons. Overall visibility is fine, with you also being able to see directly behind the car.
Double din AV - I did this and space is tight and - as previous comment, you need to work out your vent pipe routes, but I managed to get effectively a flush fit after a few mods to the Din surround and fiddling about. I mainly went for my unit for sat nav capability and camera input (camera useful when reversing. I personally wouldn't bother with 2nd monitor screens - you'll find you use your mirrors to scan traffic behind, not the camera screen.
Regarding aeriels, I went for a flexi rubber 10 inch aeriel, mounted off the bracket in the lower front of the right hand side pod, where Ultima traditionally bolted the brake servo (if I remember correctly). Radio signal is fine (for FM) - and the sound system is useable upto approx 60mph, and certainly ok when in traffic.
