show your wheels!

I'm not saying it's not good, by any stretch! Hahaha, I'm just not understanding why it's better to go with the 850 wheels according to bondoboy. Unless you actually care about the strength of the wheel and having both lips better supported by a slightly more centered center. :e-shrug:

No dude you're confused. You are widening a 6" rim. You wont' be using any spacers.

If you start with an ET40 you end up around ET10 or ET15 which is a good offset for a 240 with an 8" wide wheel

If you start with an ET25 wheel and add 2" to the front side you end up with ET0 which is higher than you want.


Do the math and it'll make sense. the backspacing on a 6" ET40 is the same as the backspacing on a 8" et10 (roughly i'm doingit in my head). The backspacing stays fixed. It's the backspacing you care about.
 
Well yeah, I didn't do the math(still didn't), but was(and still am) of the opinion that you can't bolt a 15x6 ET43 wheel on a 240 and have it fit without rubbing on the inside. I mean, considering a Draco with a 205 tire and ET25 will rub on the inside of the rear as it is...

Maybe you still have those goofy crash triabgles still installed becuase you're way off here.

You're limited to around 5" (127mm) of backspacing on the rear of a 240.



Back spacing on a 6" wide et43 wheel is 97.7mm

Back spacing on a 7.5" wide et20 wheel (like an eiker) is 105.5mm

Back spacing on a 8" wide et10 wheel is 106.6mm

So according to the math you aren't doing neither an eiker not a 8" et10 wheel will fit on a 240.

18x10 et5 fit on the back of a 240. That's 124.5mm backspacing and right on the edge..

5.25" fits, even with a fat tire. More is possible as you know.

your calcs are

1. 131.9mm = 5.19"
2. 127.95mm = 5.04"
3. 124.3mm = 4.89"
4. 144.7mm = 5.70"

Wheel width at the beads plus one inch times 25.4 = overall width in mm
divide by two and add the offset
=backspacing

6" ET43
overall width is 7", or 177.8mm
divide by two (88.9) and add offset (43) = 131.9mm backspacing
 
LOL. Yeah phone post ftl. :oops: Did i just discredit myself?:lol:

Ultimately my point remains the same though :rofl: - you're better off starting with as much backspace as you can get away with when adding "lip" to the outside, and 6" ET43 has an ideal amount of backspace for widening for a 240.

They have less backspacing than my 9" et8 which fit fine so I don't see what the problem is.

Might need a little bit of spacer in the back but you can get much wider with less pulling starting out with the higher offset wheels. If you us ewheels that are already RWD offset the actual offset after widening gets very low...

Well, you could then widen both sides as much as necessary to get maximum inside width without using spacers.

Basically, I'm talking about lack of clearance under articulation, which some of our cars may not experience as much as others.

Must also consider wheel diameter on the front since the strut is tilted. Max backspacing will vary with wheel diameter.

15x7 ET12 or my new 16x8 ET0 rarely rub on the inside rear. But the other car with 8" ET20 will rub quite a bit on articulation. I have felt the car decelerate from the tire rub when pulling into a driveway at low speed.

Some BCW wheels for BMW 5 series, rebuilt to fit Volvo, need spacers though. 8,5x17 et20:

Haven't tried them on any of my cars yet.



I also have a set of BBS something, 8x17 et 40, unfortunately no pictures,
a set of PCW something ugly ones, like those on the Ford Capri earlier in this thread. 7,5x17 et 20, will use those on the track I guess.

I also have a set of 8x18's and a set of 8,5x19's for the S80, unfortunately no pictures.
