Hello!

I wanted to know what are biggest spacers i could put on: Wheels: Front and Rear: 8 x 18, ET 20

But i dont want to do anything else on the car.

Greets

 

id say 5mm spacers.

 

Are you sure?? I thought on 20 or 30 mm on each Wheel??!

 

I'm doing 7mm front and 10mm in the back

 

I am doing 12 or 15 in the in the rear

 

Depends on the tyre width you plan to use. It Is almost impossible for the rim to rub to the fender, or to the wheel wells.
Ie. an 8J rim with 10mm spacer fitted and with a 245 tyre mounted won't rub, whereas the same setup, but with a 255 tyre, may rub.

Assuming that you have the stock 245 tyres all around, you can go for up to 7 mm spacer - 8 mm max front and up to 15mm spacer - 16 mm max rear, leaving space for a 2-3mm gap.

Available space front stock with 8JX18ET20 and 245/40R18 tire: 10 mm
Available space rear stock with 8JX18ET20 and 245/40R18 tire: 18 mm.

 

Hello Nick!

I have measured > 25 mm free space till the fender edge...

In the past summer i had 20 mm all around, but there was even more free space... soi thought on 30 mm??

i have 235 / 40 / 18

thx

 

Are you sure you have measured the free space with the car fully loaded so the springs to be pushed to their lowest position, where the rubbing occurs?
At front, the tire is rubbing to the inner plastic wheel well's center - right above the tyre, not to the fender's arch.
In the rear it will rub to the inner arch, between the upper and the rear end of the wheel arch.
You can only measure correctly with the springs fully pressed.

If you have 235/40 then you can add +4 mm to the spacers above.

 

then the 20 mm all around were quite the limit??

thanks

 

The spacer limit for 8JX18 with 235/40 R18 tyres is 14mm front - 22mm rear (with my personal measurments of course)
