Replacing my wheels, Need some assistance and advice Options

[MisterRay]

a few months back I snapped another set of 18s on the passenger side after driving through a big pothole (seemed like roadworks but wasnt signed up) currently im using my OEM 16s so its definitely time for an upgrade.

what i want to run...

XXR 527 - Flat Silver
16x8.25
ET0
195/45/16 tyres

since my rear arches have metal cancer at the moment and are rusting away i thought this would be a good opportunity to just cut them out and replace them with some universal fibreglass wide fenders.

I also want to run some 25mm spacers and have some mad poke. my car is lowered 25/30ish mm and is on springs (will be getting some Megan Coilovers soon too)

what i want to know is:
1. will i be affected by a lot of camber if i space the wheel out that much and how can i counter it?
2. what size fenders should i go for? i dont want them to flare out way too much. maybe some 40mm?
3. is there anything in general that i should be aware of?
4. this is the kind of look i love and looking to work towards, any suggestions on how to get close to that?

gotta love that unfinished primer look!

p.s i would rather do this look without extended arches and just cut, roll and pull the crap out of originals but its not possible with the rust is it?
