WJM Posted August 23, 2004 Author Share Posted August 23, 2004 Ok, so whats the stock offset for the stock SUBARU 13x5 suby rims? 40 something MM? Quote Link to comment Share on other sites More sharing options...
GLCraig Posted August 23, 2004 Share Posted August 23, 2004 Actually Offset and Back space are 2 different things. Here's a link with okay deffinations of both http://customwheelsmarket.com/wheelter1.html Are you looking for specs on EA81 or EA82 Wheels? There is a difference in the backspace and offset between them. This has to do with EA82 needing additional clearance around the brake caliper. Also the Stock sice for a GL is 13x6 some EA81 DLs got 13x5.5 Quote Link to comment Share on other sites More sharing options...
JWX Posted August 23, 2004 Share Posted August 23, 2004 If you have one loose (not on a car) just put something nice and flat over it and measure to the hub mounting surface. and what kind of wheels are you getting? Quote Link to comment Share on other sites More sharing options...
WJM Posted August 23, 2004 Author Share Posted August 23, 2004 thanks GT. JWX: I am looking for some 15x8's. Some 225/45/15 Hooiser's are going on them. Quote Link to comment Share on other sites More sharing options...
Warp3 Posted August 23, 2004 Share Posted August 23, 2004 What GLCraigGT said. Basically, offset is measured from the center of the wheel and backspace is from the inside of the wheel. Here's a good example for using wider wheels: If you go from a 6" wheel to a 8" wheel and keep the same offset, then the wheel extends 1" more on the strut side and 1" more on the fender side. But, if you do the same and keep the same backspace instead, then the whole 2" will be added to the fender side. Most people, when upsizing wheel widths, tend to reduce offset (thus making the wheel stick out farther) as it's easier to change your fender for clearance than it is your strut...LOL Also, as a rule, domestic applications tend to use back spacing more often (measured in inches) and import applications tend to use offset more often (measured in millimeters).
