It does depend on where you are rubbing @ 3/4 turn .
If it's the fender wells plastic black liner on the inside , you have a few options .
1) You can cut that ****** liner with scissors or xacto knife .
2) 10 mm hub centric spacer aprox. 1/4 " .25" ( not .4" as stated above ) it's important to understand this is a spacer not a wheel adapter. .
3) wheel adapters aka spacers .
Wheel adapters have wheel studs on them .
As far as a 2" Bora spacer goes this would fix rubbing on the inside , but may cause the rubbing on the outside at full lock
Does your wheels have a bored out area to accept the OEM studs protruding through after the wheel adapter is installed ? If not you will require trimming of your oem studs or installing shorter ones .
If your wheels do have a dished out or bored out area to accept studs from the adapters then it's simple math : measure the depth of the bore = example =.75" bore depth .
Next measure the overall length of your OEM studs = example = 1.75"
To determine the minimum thickness wheel adapter you can install with your wheels bore depth ( if you have this ) known and your OEM stud length known :
Stud length. 1.75"
Bore depth. - .75"
= 1.0"
1.0" thick wheel adapter would be your minimum thickness adapter that could be installed without interference between the oem studs and your wheels mounting surface . ☆☆This is just an example , every setup must be confirmed and measured ☆☆
Hope this helps ! Good luck !
