A quick guide to understanding Rim Offset / wheel offset for those of you buying some new rims for your cars, as the wrong offset can make a set of rims either not fit at all, or just not give you the right look :D Its all pretty simple, and the pic should be a huge help :P

The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types.

ZERO OFFSET

The hub mounting surface is even with the centerline of the wheel.

POSITIVE OFFSET

The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.

NEGATIVE OFFSET

The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.

Something that is also very useful is the offset calculator. Give you a measurement of the difference between your current wheels and your new rims. Will help you work out if those new rims will fit - clicky

Just as important as the offset is the disk type for some Japanese rims, or just the clearance for rims in general - make sure the spokes clear the brake calipers before you pay for them.

Made an expensive mistake in ordering Volk GT-Cs which arrived with a B-disk type which didn't clear the stock Brembos on the front of my R33 GTR.

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
