According to the information on the sellers website offset in front is 32mm, in rear 20mm. Wheel sizes are 8.5x19 in front, 9.5x19 in rear and I have Continentals Extreme Contacts DW 245/35 in front, 265/35 rear. There are no modifications to the suspension of that car.
What size spacer I can install on those wheels without worrying about rubbing?
Looking at the size and offsets of the wheels you are looking to put on your car, you should be able to fit a 15mm front and 12mm rear without any issues on the conservative side. You can probably even fit an 18mm in the front and 15mm rear, although I do suggest to measure it before hand to see how much you want to bring the wheels out. If you have any other questions, feel free to PM me.
