Wheel distance from brake caliber

I found nice wheels from ebay UK. The wheels are 19 front 8,5 ET35 and rear 9,5 ET38, so i think the ET should be ok, maybe 3mm spacers to front and rear.




But little concerned that is the wheel going to take contact for the brake calibers( in front wheels). So how much free space from wheel connection point and the wheel frame (horizontal) should minimum be?


And yes i can measure it my self, but car is outside and here is -32 degrees Feel quite bad for the car when i started i't in morning

Offset is the key. I have 19" wheels on my SLK 55. Offset is 32 front and 35 rear. While the offset you stated is not ideal, they SHOULD work. SLK 55s with larger front calipers create the most problems with offset.

The offset should be ok.
For the frond to clear the caliper the wheel spokes should be close to the outer rim lip (look like for a FWD car)

And no minimum distance as far as I can tell; the distance between the spokes and the caliper can be incredibly small. On my car with OEM brakes and OEM wheels, there is barely enough room to put a tooth-pick in.

I would go for a minimum of 2mm to allow for thermal and flex.

Ok i bought wheels and tyres and tested them today...and find out that front wheels take contact to brake calibers, so i tested the wheel with washers, and find out that with 10mm spacers the front wheels works, but the tyres and wheel come little too much out (i was going to use 3mm spacer to reduse offset to 32mm). Rear tyres came out about same than front with 10washers.

Front 19x8,5 ofset 35mm tyre 235 35 19
Rear 19x9,5 ofset 35mm tyre 265 30 19

I't seems that the tyres are going to rub the fenders, i have normal slk350 suspension, but i don't know is the suspension going so low that the tyres will rub the fender?

Now i have to think am i going to sell the wheels/tyres or will i try to drive them with 10mm spasers in front

Ooh yeah, that's not a good look. Has a bit of that cholo low-rider vibe going on...

i Checked the offset from the wheels and it was rear 35 and front was actually 32. so in paper all should be fine. Ok front takes to the brake calibers. But why the rear is coming so much out with right specs?
So to find the right wheels from ebay is not easy

I tested one more time for the rear wheel, because i measured the wheel and calculated right specks with 35mm offset and found out that the wheel was correct. Ok and now the rear wheel worked fine, so first time when i was in hurry testing the wheel my wheel bolts where too long and bolts didnt tighten the wheel correct and when lowering the car with jacklift the wheel had been moved and thats why it seemed that it was coming too much out I wanted to tell that 19x9,5 et35 works fine with 265/30/19 in rear so that there would be no confusion when reading my posts.

I sorted rear but the front still would need 10mm spacer in SLK350. So can't use those wheels


This pic the rear wheel properly in place

And this wheels just side of car, bad pick

So i have to buy new wheels have been thinkin the Axxion AX2 i think AX2 would work in front also. AX2 is not black from center.
Some how i like the look of those first wheels.

Adding a 10mm spacer to a wheel with an offset of 32mm affectively changes it to 22mm.

But the front wheel came too much out with that 10mm spacer it would have been rubbing the fender and thrown the dirt to cars sides
Maybe those wheels would work in SLK 200 with smaller brake calibers

Dont make the same mistake. The AX2 is a BMW wheel.
BMW uses a C-Clamp like brake caliper with pistons only on the inside, so there is little caliper protrusion to the outside.
If you again need an 10mm spacer to clear the brakes you need to start out with a wheel offset of 45mm.

I was asking those ET45 wheels but that seller didn't have those only 19x8,5xET32 to the front. I measured from my car that the wheel would need free space about 50mm from connection point to the wheel spokes.
So if i buy those AX2 wheels seller have to confirm me that there is minimum that 50mm free space. But i haven't decided yet what wheels i wan't, but it's hard to find good staggered wheels with the lip that fits SLK350.
Thanks for warning for those AX2
