Wheel Spacer Question

**StevenStarke** · 12-31-2015 03:16 PM

I have a 13 S4 that originally had 19" peelers which I sold. I now have 18" rotor replicas with blizzaks on, endlessly preparing for snow. So I bought ECS spacers thinking they would bring the wheels flush. I bought the 19 peeler OEM wheel flush kit though, which is 8mm for the front and 12.5mm for the rear. I put the rears on first and then realized the rear wheels are still not flush, they do look much better, but they are still 3mm-7mm from being flush.

Of course I go to put the fronts on and the spacers don't sit flush into the wheels because they're designed for the peeler style. So now I just have the rears on. On eBay, I see multiple sets of 10mm/15mm with bolts, but they always say they don't fit the S4/A4. Is that because the front OEM wheel design? Because if that's the only issue, than I should be able to use them. Anyone the answer to this question?

My options are:

Sell the whole set, buy a 10mm/15mm kit from wherever (if I can confirm the fronts will fit with aftermarket wheels)

Sell just the fronts, buy regular 8-10mm ones from ECS. My issue with this though is that then I have a mix of a kit that will prob not be worth anything if I go to sell in the future.

Looking for info/suggestions. Thanks in advance.

Hello,

The first question is : What are your wheels specs ? (Width and ET)
And then you should know what to choose.

I don't know exactly. I bought the car with them

I don't think anyone is going to care whether the fronts and rears are matched when buying used. You may not be able to sell them as a full set later if the spec is odd ball.

I believe there has been some discussion about spacers less than 10mm. Above that number and there is a small ring on the spacer which helps to center the wheel; below and there isn't enough space to machine the additional feature and you're relying on a very small lip from the factory hub to center the wheel. I think I may have read where some people were concerned about the wheels not being concentric to the wheel bearings because of misalignment allowed by this condition.

Ok so I spoke to the guy I got the car from. Wheels are 18x8 35mm offset

So you will have some troubles having spacers:

Let me explain:
8" wide + ET 35 = 8.5" wide + ET 41 (whereas stocks 19" are 43) so you poke 2 mm further than 19" OEM peelers or rotors.

for a quite conservative set up, you would need 6-8 mm front and 8 mm rear

But i would personnaly stay away from spacers Under 10 mm : they do not have any centering lips (--> vibrations ) or only too little centering cone (like the ECS 8mm) that may lead to too much stresses in the lug bolts .

Yours wheels are still quite well without spacers anyway.

Best regards,

Mathieu

Edit: I re read your first post and i am verry astonished that your ECS flush kit don't flush well... Maybe Something is wrong ? did you have the correct wheeles specs??
