Appreciate the comments guys! Thanks!
Regarding the wheel/guards.............
I don't know what the actuall offset is. It says 13 7jj or something like that on them. When the car was at standard height, there would have been no problem with the rears. Once I lowered the rear though, you definatly have to roll the guards with these wheels. So my brother and I got out the trusty Monroe shocky that I pulled out of the front and rolled the guard. The problem I had, and most other '55 owners would know, is that the guard was heavily rusted from the centre of the top all the way to the rear. This made rolling the guard out difficult. (I have done this on other cars before no sweat). The other factor for me is the tyres I have. They are extremely square and will slightly rub even with my d.i.y rolling job. With standard style 205's I really don't think you would have a problem.
Now the front............With the same d.i.y roling job and very stiff springs and shocks, they won't rub the outer guard. But the problem lies with the rear inner guard. When on anything over 2 turns on the steering wheel, the outer edge of the tyre will hit the rear inner guard. There is also a seam right where it hits. Now with standard rounder profile tyres you may not have this problem. Infact, a friend had exactly the same rims but with more stand. style tyres on a '55 coupe and had no dramas. But it wasn't as low as mine. This is fixed in my case however, with a blockbuster!
I'll post up some pics over the weekend, hopefully I can help.
