2002 Clio 1.2 Wheels

Hi I have slight problem with my clio because I would like to fit bit bigger tyres and rims that ware stock and this is where my problem comes in to play I fit 195/55/16 at the rear but they won't fit at front as front suspension takes lot of space...
and I'm planning on lowering the car on 40mm lowering springs
so what size of spacers should I get in order to fit those wheels? or should I go back to 185, 15 inch wheels?

Thank you for your time!
