I was looking into possible getting these.
I see they only have 4x100 17x7.5 ET30 or ET42

I do not fully understand offsets
Would these fit well on an e30 currently on H&R springs.

Thank you for any/all input

you will need a spacer to run those.

that et30 and et42 means that the mating surface where the wheel sits on your hub is 30 and 42mm towards the outside of center of your wheel. so if you lay a straight edge on the inside of the wheel and measure to the mating surface and then do the same from the outside of the wheel lip, it will be more towards the outside by those many millimeters. an et0 means the mating surface is centered in the wheel.

stock is around et20, if I remember right.

but, google wheel offset and you will find something explaining it will visual aids to help you see it better, if you happen to be someone who learns easier visually. some people are and some people aren't, its just how we work
