M-Sports require a huge spacer?

[pit viper]

I know I've seen A6's running M-sports before, but I got my 19" M-Sports home, and it looks like I'm going to need a huge spacer to fit them on my 2000 A6 Quattro?? They're hitting the caliper with what looks like 1" of spacer still needed.

Anyknow have knowledge on this??

What's the offset of your wheels? Because of the design of the wheels I'm guessng you might need a +30 offset.

So if you wheels offset is something like +45 you'll probably need 10-15mm spacers, thus also needing longer bolts.

Now all of thing depends on what model A6 you have. I know 2.7T needs higher offsets because of the front calipers. I'm not sure if it's the same issue with 4.2 models but I'm pretty sure 2.8 models doesn't need lower offsets.

My car is a 2.7 with the hp2 (something like that) calipers.

The wheels are 19x8.5 with a 35mm offset.

I have to run a 5mm spacer with my 19x9.5 et 35 wheels on 4.2 C5 A6 with Lucas HP2 calipers.

So you'll probably need the same.

Longer bolts are necessary as well.

Ya I just got some R19X8 RS4 reps with +35 offset and the front calipers rub for me too, I need some 5-10mm spacers.

Because you have around 1.5" lip I'm guessing you might need the same size spacers, don't forget longer bolts.

holy cow, I need a 20-21 mm spacer to clear the front calipers.

[2.slowT]

yowzer! Do they even make that? Does not sound safe.

how did you come up with 20-21mm? That's way too much IMO.

I put dowels in the lug holes, and kept stacking washers on them until the wheel actually cleared the caliper by about 2mm or so. I then measured out the washers, and it took 8 of them, which measured 13/16", or 21.6 mm.

[2.slowT]

Well you probably cant get anymore accurate than that.

I also would not use that big of a spacer. Are you even considering it?

[pit viper]

Motherf**ker.

I measured out the rims. The backspacing is 7", and the total rim width is 9.5". If I calculated that out correctly, that leaves my offset at 57mm. WTF?? How is that even close to 35mm??

So, now I have to contact the company and try to resolve this issue. Dammit.

[2.slowT]

Thats good you figured it out. Hopefully they will just exchange since they sent you the wrong ones.

[pit viper]

Anyone want to double-check my math on calculating the offset? The company I got the wheels from has responded promptly, but they're confused too, as they say ADR only makes the M-Sport 19" in a 35mm offset.

[deucescorner]

just remember though, even if now you clear your calipers by 2mm now, when you change pads and rotors the the calipers will expand, so if you haven't change your brakes recently chances are if you get them changed 2mm now might not be enough

Regarding you calculations, it seems rght. I think the best solution is sending them back and asking either to make sure the offset is really +35, because you calculations seems right on.

I haven't seen Msport on C5 body with hp2 calipers, only on B5 and B6.

And I wouldn't run 22-25mm spacers which would make you bolts way too long for my personal safety comfort.

[pit viper]

Calipers don't expand. The pistons within them do, but the caliper body itself remains static. Anyway, just replaced the pads & rotors about 400 miles ago.

The company asked me to call ADR, and gave me the number. We'll see what comes out of this.

Sounds good, keep us posted on what ADR has to say. Did the company you bought the wheels from offer no other solutions?

[xpl0sive]

if you do end up going with 20mm spacers, they will be the ones you screw onto the hub, and then screw the wheels onto the spacer, so as far as safety goes you should be ok, the only thing is, with that much spacing, the wheel might stick out way past the fender...

[pit viper]

Apparently measuring late at night is not the best idea. The offset on the wheels is actually 35mm. However, the wheels would still need a 20mm spacer to fit, due to the brake caliper. :(

sorry to hear that, hope everything works out

That seems kind of odd to me that your 2.7t would have an offset of +15, therefore requiring a 20mm or larger spacer to meet the 35mm offset of your wheels.

Not that I'm doubting your methods, but I'm sure others who have the same model as yours that could verify the OEM offset of the 2.7t.

+15 seems a little too tucked in...but i guess it's possible.

Anyone with a 2.7t can help this brother out?

[pit viper]

it's not the offset to fit the wheel. It's making it clear the caliper.
The wheel would have to swoop out more to clear the brake caliper.
It looks to be about 2" from the hub mating surface to outside edge of the caliper.

[lodit]

I think I see what you're talking about.

You're saying the spokes on your wheel are more flat rather than curved to accommodate the size of your calipers.

So, in order for your spokes to clear the calipers is the reason you need such large sized spacers, not the wheel's offset.

Got it. Using such large spacers will probably require re-alignment as well due to pushing the wheels out that much. Just a safety precaution.

[pit viper]

Yeah, I'm not sure I can/want to do it. I"m trying to find some 5mm spacers locally to stack on and see what's going to happen to the wheels.

Do other A6's (non-HP2 caliper) have calipers that don't stick out as far? Because these wheels are listed as fitting all 98-04 A6's, and I know I've seen pictures of it on one.

35 - 40mm is standard. The stock sport BBS is actually 43 but thats on a 7.5 width.
