Advice on 5mm spacer or 3mm
 
I had some rubbing issue in the front, so I added a 5mm spacer and I was able to get 8 full turn for the lug and torque them to spec.

How ever i am still very sketch with a 5mm spacer with oem stud.

my question is would 8 full turn be good enough, or should i swap them out for a 3mm spacer?

my worry is the 3mm might not give it enough room to clear

PS: wheel size is 17x8 48. im rubbing because I have neg camber up front, with oem struts

Thanks!

How much neg camber? At that offset you can go 15mm and skip the stock studs.

-2 up front. I'm not a fan of hub spacer.

I don't really care for flush fitment. I'm just hoping the 3 mm will clear the strut seat.

Did some research online and people say 8 turn on the lug is fine. So I'm not sure if I should keep my 5mm or not

General rule of thumb:
The length of thread engagement in a steel nut should be equal to or greater than one full diameter of the bolt.
m12 1.25
m12=12mm
1.25x8(turns)=10mm
Answer=no

Many people run 5mm... and the real answer can be found if you were an engineer and knew what material the lug nuts/studs were made out of and did some formulas.

^edit... On other cars that have m12 1.5, 8 turns would be 12mm of engagement.

I'm going to try a 3mm tomorrow and see if it rub

I'm definitely not a big fan of any sort of spacer but to get them to fit without rub either I have to run a small spacer or get a different set of wheel with a lower offset.

Love my current set up its hard to find something better :(

Or get extended studs or larger bolt on spacers like 20-25mm

If you have extra time and money, I would change the studs. Eibach and H&R sells 10mm longer studs with 10mm spacer. I used Eibach and my tires clear the strut tower even with -2 negative camber. Just another peace-of-mind option.

To add another option - B2 Auto Designs sells extended studs I'm currently running them and they held fine even on track condition.

thanks for all the help guys.

Im going to grab Ichiba v2 15mm hub adaptor spacer all around.

I have about an inch of extrusion on the hub of my after market wheel.

so it should fit nicely!

also I can run a wider 245!
