To buy or not to buy wheel spacers and why

Did you have to trim your studs to fit 1” spacers?

 

No, the spacers use the existing studs to mount, and have other studs you bolt the wheels to. Don't forget your loctite, and to re-torque them all every so often. I had my Spidertrax on at 400 miles, currently at 20k. No issues and no dealership hassles.

 

You shouldn't have to trim with 1". I have .75" spacers, and didn't need to trim, because my rims have recesses between the bolt holes. But with 1" it should work, even if you don't have the recesses, like its flush the whole way around.

I can post a pic of what I'm talking about if that doesn't make sense.

 

That makes perfect sense, thank you for taking the time to explain.

 

Hello,
I'm not sure if I want to leave my truck as is, add a hub centric slip-on spacer (not the Auto Parts types) or a Spidertrax or Bora wheel adapter. It is strictly for looks. My '08 Prerunner had Maxtrac spindles up front so I ran 1.25" Spidertrax on the rears to match the fronts track width & I really liked that look. My 2015 DCSB TRD O/R 4x4 has 2016 4Runner Trail wheels. The Tacoma O/R wheels have a 30mm offset & the 4Runner Trail wheels have a 15mm so the Trail wheels "stick out" almost .6's. If I add a Spidertrax 1.25" adapter/spacer the wheels will stick out almost 1 3/4" over the factory set-up. I was thinking of adding a .75" sandwich style or slip-on spacer from Bora

These are hub centric to the hub & to the wheel so it's like a Bora or Spidertax wheel adapter minus the built in studs. Of course, if I go this route I would need to go with ARP extended length studs or Toyota Matrix studs. Either of these should be long enough to accommodate the slip-on spacer and have enough stud for the lug nut to safely grab on to.

The pros of the slip-on style spacer is that there are only 6 studs/nuts vs 12 studs/nuts per wheel but I don't know if the lug nuts can loosen over time with the slip-on style spacers since the studs are longer and the spacer is only sandwiched in between the wheel & hub. Anyone here running these type of slip-on spacers?

Thank you
