I am running LS400 calipers, wanted to know what do you guys think would be safer.

Either use extended studs with15mm slip on spacers

15mm Spacers with attached studs

Let me know what you think

Thanks guys

 

Your good either way, but extended studs would be considered safer, as it eliminates 5 more lug nuts and their torque requirements.

There is a reason alot of race tracks don't allow bolt-on spacers on tracked vehicles, but do allow extended studs with slipon spacers.

But bolt-ons are generally just fine as long as you keep them properly torqued. Of course please buy quality billet spacers as well.
