I have had these volk gt-7's for a while now and every time I take off the wheel I look for an offsets making. The sticker that I see on other volks that have the offsets or ET printed on them is missing on all 4 wheels. I have these 2 pictures of the pictures on the inside of the front wheel




Can anybody tell me if there is something here that can help me solve the case of the mystery offsets? There are etchings on the center where it touches the hub, but nothing that indicates the offset. Any help will be appreciated.

 

Check the backside of the wheels around the hub, their might be some info on them.

 

I've checked there, thank you though

 

Offset will not be printed on a two piece wheel as there are many different barrels and faces that can complete a wheel. At one point in time there was a sticker aligned with the others that gave specifics, but that tends to be that sticker that ALWAYS falls off.

 

that's a good point, never thought about that. I wonder if there is a way that I could enter the No. # and get info from that. I'm the second owner. first bought them new in 2004 I think he said. He also did not recall the offsets, he just asked the sales guy for something that would fit over the oem Brembos and are 19x9.5/19x10.5

 

You could always measure the offset...

 

I've tried but at this point I'm convinced that I am measure challenged....

 

welcome to the club

 

Since we have no idea what the offset is, "close enough" will work. Take a tape measure and lay it through the spokes across the barrel. Find the center of the barrel. Take something rigid and with a flat straight edge (e.g. a short level) and stand it up on the inside of the barrel with one of its edges lined up with the wheel barrel center line. Hold it there, then take your tape measure and measure the distance from the hub mounting surface of the wheel to the straight edge of the level. That's your offset.

 

^ that sounds much easier than the other ways I've read. I will try this and report back. Since those 2 stickers that in took pictures of are still there I wonder if I can just contact Makin (sp?) and see if they can give me specifics.

 

^ Lol cmon man, its sooo easy. Probably easier than calling around reciting all those numbers over the phone...

Since you know the widths,

Measure from the hub pad to the wheels back edge, keeping the ruler parallel with the barrel. Take this number and subtract it by half of the wheel width. Convert to mm.


1" = 25.4mm

 

^i'll try that too. I usually wouldnt care because I love the fitment, but on the forums and for people that know wheels offset is a good thing to know.

 

nice fitment indeed! love the ASM hood too

 

d'oh yep! Much easier than what I was telling him to do.

 

If you have trouble finding the middle of the wheel with accuracy to 1 mm you can always lay the wheels one their faces on some carpet or something, put something flat across the wheel, then measure the backspacing to the mounting surface. There is a calculator on the CCW Wheels website the converts BS to Offset in their technical section.

 

Looks like it's around +10mm. I prefer this method for measuring offset:
