^ good read on this guy's method Project - More Rubber - The Autocross Forum

I machined some aluminum wheels for a concept model using a similar, but much more rudimentary method. Of course the wheels for the model were only like 4" in diameter, not 18"+ too.

yea, he's got it down.

any info on weather or not lips can be added/welded into wheels that don't come from the factory with lips? (material aside) wheels like TE37's, AME SPORTS FS-01, etc?

Just built up a set of OZ futuras for a mate. New rear lips in 3.75" making the rears 11.75" wide, fronts are 9.5". Tyres got put on today so fitting time tomorrow.

I wish he would have shown what he cut them on. My friends old shop had some lathes in it you could chuck a 24" wheel into but like atutt said, they are money and about the size of a tank.

Dunkz, did you use Titanium Touch? How do you rate their service?

Awesome, really good company to deal with. Used them loads of times now. Always give me a good discount.

dunkz dont suppose these are the same wheels are they?

I mean the actuall ones?

Dunkz

Nope, not the same dude, they never had as much dish as that when Stu picked them up. Thats why we bought wider lips and put the rear lips on the front barrels. Got them onto the car on saturday. 12J rears 9.5 fronts

flame me all you want but i think some s13 se's polished with a 3" lip added would look baller thats just me though.

i have a set of 15x7 0 Offset Epsilon mesh wheels. if i wanted to get them widened an inch or two they would do it from the back im assuming making it a more negative offset correct? is there a way to do it to where it could become positive?

adding width to the back side is going to make it more positive in offset.

blueshark123

it will actually become more positive if added in the barrel not lip

edit: damn u beat me ^

Flicktitty

Thank you, it's been a long day already.

That rear fitment is bloody spot on. Know the offsets by any chance? I'll be making my Meisters wider with Titanium Touch I reckon.

Fronts are a bit crazy!!

wouldn't you have to take away from the backside of the barrel and add to the front to make it more negative?

no because you are making the wheel wider but not changing the position of the face relative to where it started. thus adding more wheel to the outer lip will push the face in relative to the wheel's new width.

GabeS14

I think you both said the same thing

no he said something else i get what e-double said. People need to understand how offset works when widening wheels.

Mister.E

glad someone understands my gibberish. it's hard to explain the concept of wheel offset to people online; much easier in person.

Dunkz

I'll need to double check as I can't remeber now, It's got a 265 tyre but we could only pull the arch so far as its rotten, gonna have to go for over fenders to get the wheels stood upright again as there's a lot of camber on it. I'll drop you a pm when I find out. Front fitment was extra spacers as a test to see where it would go as its gonna need front arches to match the rears, its not actually running like that.

I'll drop you a pm.

they both said the same thing lol, i read it 10 times.. one asked if taking away from the back side and adding to the front would lower offset, the other responded with no, but then went ahead and said you need to add to the front lip to lower offset, so yes, they said the same thing.
overall they both meant that adding more lip lowers offset.
because you are comparing the location of the center piece in relation to the new overall size of the wheel.
so if you had 5 inches of rim on inside barrel and 3 on outside your offset would be XX and if you reduced the size of the inner barrel and increased the size of the outer barrel, you would now have -x offset(lower)

Is there a such thing can change from 16" to 17" or 18" diameter?

Mister.E

i just re-read it again, he is asking if you HAVE to take away from the backside and then add to the front side to make it more negative; and the answer is NO, you do not. Simply adding more material on the front side will make the wheel's offset more negative relative to it's new width.

fckillerbee

wow...offset is really easy to understand.

it's measured in correlation to the center of the wheel. 18x8 0 offset (4 inches on each side of center)
18x10 0offset (5 inches on each side of center)

add one inch to the face of 18x10 now equals 18x11. a zero offset will have 5.5 on each side of center. If the mounting point was zero offset at 18x10, adding one inch changed the location of where the center of thr rim is. Now you have to measure from center (0 offset) to the location of the mount (which was zero offset on a 18x10 now 18x11) in which 25mm equals about an inch, you should have a rough -12 offset (add one inch is half an inch on either side of center (zero offset).

offset is measure from center to the mounting position. Measure in mm. positive offset if mount is past the center (less lip, more back spacing) and negative is opposite (more lip, less backspacing).

I hope this helps ;D

Mister.E

if you add an inch only to the front wouldnt the new mounting position essentially be 25mm less than what it was before? now making your 18x10 +-0 wheel into an 18x11 -25.

im having trouble seeing how adding an inch (25mm) to the front is only going to effect the mounting position by 12mm...

Dunkz

Yes, but that gets expensive, if you had centers from a flat dish 17" wheel it's possible that you'd be able to put stepped lip onto it from an 18" but that means new barrels and lips.

GabeS14

but all in all his analogy of offset was correct..
i suck at math and wont try to verify it lol..but he did make it sound simple to the guys who were arguing about it.
