I don't see many wheel manufacturers producing the high offsets our s2k's have. What is the reasoning behind having such high offsets?

Thanks in advance

 

offset I think should 45 in the front and 55 in the back. I dont know why too. that just the way it is

 

Offset is determined by the design parameters of the car itself. The wheels and tires have a "desireable" positioning in the wheel well. If they stick out too far, you'll get a change in cornering characteristics or possibly more stone chipping on the sides of the car. If they aren't far enough out, then those characteristics will be affected in another way plus the car's appearance may not be what the original designer wanted.
A car must fit all of those suspension components in a certain way to do the job they need to do. Drive shafts, axles, wheel hubs, CV joints, etc, need to be where they need to be to do what they need to do. Then there's the body. It has the shape and dimensions that were called for in the drawings. So, in order to fit it all together so it all works the way it was meant to work and look the way it was meant to look, wheel offsets are then called for to work in harmony with all of these other factors.
I don't think it's a matter of building a car and then going to a wheel manufacturer and saying, "OK, give us what you've got. We'll take 50,000 sets of what you've got hanging around."

 

Wow, thanks for the clearing that up xviper. Your knowledge of the workings of an automobile are astounding!
