So I've been searching across the forums for an answer to my situation.
I don't mean to write new threads, but I'm short on time and need answers soon so I can decide whether or not to purchase them

My situation:
Im currently driving stock wheels on my C240, (205/55/16) on stock suspension, and was wondering what modifications to the wheel well I would need to do in order for new wheels to fit. I've read about getting 10-15mm spacers and longer bolts with the M14 head.

W211 AMG- Staggered Wheels:
Front- 18x8 on 245/40/18 Tires
Rear- 18x9 on 275/35/18 Tires

So my questions are:
Can I slim the tire size down for better fitment?
Where can I find a set of spacers and new bolts for this setup?
Will it poke outside of the fender?
What would I need to do if I plan to lower the car in the future?

Again, Im sorry if a current thread already addresses this specific issue, I do not mean to repost, just need some help.
Thanks.

I would say don't get it since they have a different offset and the tires may be to big and rub on your fender.. look for CLK55,CLK63, CLK320 Wheels, Or Any W203 Wheels or even SLK
