Hi!! I'm new here. I need help.. I have a C320 year 2002. I 'm planning to change my car rims to 19" (front 8.5 x 19" tires 235/30/19 and rear 9.5 x 19" tires 265/30/19). Which offset is good for my car? Also, I'm planning to lower around 2.2 inches in front and 2.0 in the back. Do I need to do anything with my car fender? Cause I went to a wheels shop today and they said it will not fit. I told them a lot of people have them on their w203. I'm not sure so please help me.

Thanks guys,,,

 

32 in the fron and 35 in the rear should fit depending on the wheel. atleast that is what a lot of member have been running with out problems.

as for the fenders you can get them rolled or shaved. any good body shop should be able to do that for you.

 

It's all depend on how you gonna lower the car and what kind of wheels. Basically if you plan on lowering the car using coilover or have amg, brembo even sport front break caliper, you need an aggressive front wheel offset 32 or up to et 30). Using shock and spring combo, you can have up to et 38 (if you don't have the amg, brembo or sport front break caliper).
Et 35 or more (up to et 38) should be fine for rear.
As for tires, get the rounded sidewall instead of the square one. Some people use 225/35 and 245/35.
If they rub, then follow Burnt Toast advise....
Hope this help...good luck
