I have 18"x8" OZ wheels so clearing the brakes is no problem. Also have Yokahama Paradas so they are sticky. The kit I am ordering only booosts my car from 150hp to 205hp so do you think I'll even need beefier brakes or just better pads. I mount 15" steel wheels w/ snow tires during winter so knowing I could stay w/ my stock calipers and rotors would be nice. Also, are the brakes of the C220 and C280 the same? Because if so, the C280 has around the same power as my C220 will when boosted so that will be a good sign that things should be fine. Thank you.
