What is backset and offset of a stock 86 GN wheel?

[Mark Parks]

As the title says. Also how much varience of backset and offset can the wheel be to work properly?

15x7 3.5" backspace
offset thats a metric ricer term , my guess it works out to -10

every car is a little different , tire height width and ride height all affest what you can run

typically the mounted cant measure more than 5" from tire to back side of rim mounting
8x4bs is typically ok as long as you dont run too tall or too wide a tire on it
9s with 4.5 same deal but fender lips will be an issue
10s at 5bs can be run unless tires are thin youll need rolled fenders and may need to use a little spacer to stay off frame

Does it really matter if your running stock 7s" ?? Are you planning on widening the wheels?
