I putting some wheels on my SC and its lowered on MKIV eibach springs w/ koni yellow shocks. The wheels are frt:19x8.5" rear: 19x10". What tires sizes should i go with, i will be getting the fenderes rolled and maybe pulled. the offset of the wheels are unknown..i was told maybe 27mm on the front and maybe 19mm on the rear....I want to run the least amount of negative camber as possible. I was thinking 245/35/19 and 285/30/19. Here are some quick pics...

You need to first get your backspace measurement (mounting flange to outer most part of inner wheel lip). Place your wheel face down first on a soft surface. Lay a straight edge across the diameter of the wheel. Measure from mounting flange to straight edge = backspace.
Then find the center line of your wheel (wheel width divided in half). The difference between your backspace and center line measurements will be your offset.
In general, you add 1 inch to the overall width of a wheel to account for outer lips. Wheel widths are measured by inner lip to inner lip; therefore the difference in width specs.
Your 10" wheel will be roughly 11".
Backspace - 6.5 inch
Centerline - 5.5 inch
Difference - 1 inch = 25.4mm
The difference will be your offset ~ 25/26mm.
If your backspace is greater than your center line = positive offset.
Backspace less than your center line = negative offset.
Backspace equals your center line = 0 offset.
