ok guys i am new to the german look and want to fit big wheels on my car with stock fenders i have to admit all this talk about offset is confusing is there a website that clarifies how to measure offset and if there is can someone direct me there i am not sure when it comes to wheels but i want to run 17x7 on my car with stock fenders and want to know what offset i will need to make them work

Need to know what kind of car you're setting up as well as the type of wheel that you'll be using. You can have after-market wheels made with just about any offset and bolt pattern that you can think of. If you want to use OEM Porsche wheels then the offsets are somewhat limited and may require spacers and narrowing of the beam on a standard or a different strut set-up on a super. Provide some specifics on the car you have and the wheels you intend to use. There are plenty of guys here that can help.

sorry thought i put that info in there anyway it is a 1970 standard beetle and the rims i want to put on it are 17 inch volk racing wheels here is a pic of the wheel

you will first have to decide how you are going to convert to the new bolt pattern. are you just having the drums redrilled or are you converting to disc brakes on the front and/or rear (strongly recommended) which may alter your track width and therefore change the optimal offset needed on the rims. you can assume you want somewhere in the +50 offset range (+-5mm), but that will really depend on what you do with brakes.

will you be sticking with a stock beam or going shortened?

there is a ton of info on here explaining offset, backspacing, etc. just do some searches and you will find much of it. happy to help more in this thread though specific to your car. just need more info.
