First of all because they would do me no good and 2nd because that person has gone through a good deal of work to come up with it. At the same time I don't get why people want to keep things like offsets or spacer setups a secret. I somewhat understand on full on custom modifications done to a car that someone came up with all on their own. But still in the end in this car enthusiast community we should try to help each other out where we can. Also people should not flat out copy original ideas someone else has come up with.

In the end wheel offsets and backspacing is not some black magic or voodoo. It does take some time and measuring and a little know how. Now the other stuff that Mark does with his cars is some sort of black magic. The ideas he comes up with and executes are just flat out amazing. And I can also understand what he is saying about a simple question snowballing or even worse when people ask a question about something and then when given the answer they are clueless as to what you are talking about because they have done zero research or have not even tried to educate themselves on the basics. But these are the things someone like himself is going to have to deal with unfortunately. Gotta take the good with the bad and when you are basically considered the godfather of pro touring it's inevitable.

Didn't think I was going to have to write a novel or that my post was going to turn into this. In the end like I said I can understand what you were saying to a point. All I was saying was that it didn't apply here and that you could have spent your time better elsewhere with that post or just left out about 90% of the post and still made the same point without coming off the way you did.

But no hard feelings. Take it easy.

or if you were a true godfather fan you would have every single page memorized.

The rears are 36 mm offset so I'll set axle width so no spacers.

36mm = 7.9173 in

36 millimeters is a little under an inch and a half. are you adding that to the 0 offset back
space to come up with 7.9173"?

from here http://www.mrw-wheels.com/wheel%20te...t%20chart.html
Im a United States public school grad too so I need all the help I can get.



Actually 36 Millimeters = 1.41732283 Inches, the 0 offset on a 12" wide wheel is 6.50in and 1.41732283 is 7.91732283

You scared me a bit cause I don't usually spread FUD unless its well deserved.

36 millimeters is a little under an inch and a half. Are you adding that to the 0 offset back
space to come up with 7.9173" ? Just for clarity.

0 offset is zero offset from center so that would be what ever measurement half the width of the wheel. The offset was 36mm (positive) so you add that to the center measurement of the wheel.

How did I come up with it? I just punched the numbers in the little boxes and it spits out the backspace inch equivalency. Its aliens.

Mark,

Where did you get such a screaming deal on those wheels? I need to know so I can keep my eyes peeled this Black Friday.

Thanks

Jesse

Holy cow guys cmon....25.4 mm to the inch....so 36 divided by 25.4 = 1.4173"....aka 1 27/64"
The whole world is on the metric system the proper conversions are very easy to find

There's an App for that.

I was poking around last December looking of an "Economical" one piece wheel that would fit over a 394 mm ZR-1.

I saw Forgestars on a few cars and was checking them out. I called for info and I happen to call on the Black Friday sale. The normal price is still not bad but you get what you pay for. Finspeeds and Forgelines are works of art and these are OK for track wheels.

If I sell off enough used parts I will get a set of USA made mono blocks.
