WOW.. where to start!!....
the first issue is the 9.5" rim up front.. they will not fit without massive amounts of work. speedybenz managed to fit 17x9's up front on his C43.. but he had to cut out the front fenders and weld on new metal to make the front end wider. you can make it work.. but you will need to completely modify the front fenders.
the rears are another story.. 10.5" rims for the rear will be tough.. Ive heard of 10's.. but never 10.5's, they may work. just depends on offset and for sure you will need to modify the rear fenders too.. either massive flare or new metal.
the tires you have on the 9.5's for the front seem to be a little narrow.. 235's are good on 8.5" rims and possibly 9's (but they will be stretched) and for sure on 9.5's they will be stretched.. may want to go with a 245/30/19 or something.
as for lowering.. Im running Eibach springs with #1 pads all around, and 1/2 coil cut from the front. I have 225/35/19 rubber up front and I rub on the fenders when turning, I rub on the inside of the wheel wells on bumps.. with the set up you want to do, your car wont be able to move!
you should be able to cut 1 coil safely.. any more then that and you will possibly mess up the dynamics of the spring. if you dont care.. then cut the extra half coil.
also there are no bumpstops on the front of a W202.
I dont think that you should remove the pads completely.. for one thing the thinest shim (#1 is about 5mm thick I think, maybe less) I really dont think that removingthis will add any more to the drop after cutting the springs!, they eliminate noises fromt he pring and the spring tower, plus it keeps the spring sitting in place properly.
post pics of what you have... I like to see.
