I have just made my plates in advance of rego. Just used 2mm mild steel plate and sprayed them black, having previously made up a cardboard then light gauge steel template to copy. You are welcome to borrow these if you like.
I'll take a couple of pics of both frames and add into my gallery.
Rear plate is held captive under the standard mini boot light which is bolted through to the inside of the boot at present.
Bent the steel so as not to hit the fibreglass as it protrudes downwards and out of the cavity the light tends to nestle within. Then bent the mounting arms back towards the bodywork to enable the plate to sit above and clear of the fibreglass and more or less in the same plane as the boot at that point.
Learnt you need slimline plates though to make it fit on the boot, on a GForce anyway. So I now have these on order.
For the front I've managed to use my tranny
oil cooler attachment locations to add a frame that angles the plate downward between the bottom of the upper mouth and at the top of the lower spoiler mouth.
This location has minimised disturbance to cooling air flow to both radiators and has hidden the braided line connection into my tranny cooler, that I wasn't too pleased with anyway.
I'll try and get pics up tonight.
Let me know if you want to borrow my templates, you can then have a look at what I did as well.
Cheers
