Any Adverse Affections of Wheel Spacers?

Thinking of installing 1.5 " spacers take make room for installing bigger 4Runner calipers.

A thread claimed 1.25 " spacer could be used but not sure what type 16 in wheel they meant. to give myself enough space was thinking going with 1.5 " spacer just to be safe.
Anyone had alignment issues or wheel bearing issues due to spacers 1.25- 1.5" ?

 

Why ? Pads are 1/3 bigger, rotor is bigger, and pistons are bigger. Have you done this modification?

 

Are you having issues stopping now? All affects of wheel spacers are negative given enough time. They will cause wear on wheel bearings. I say that currently running spidertrax.

 

How big a spacer are you using now ? How long have you had it on and noticed any issues yet?

The bigger the spacer the faster it will wear though right, so if youre only using a 1" or 1.25" how much faster is it really wearing the wheel bearing out?

 

I'm running 1.25, I’ve had them on for about 40k miles. Anytime you add outside leverage to a bearing like a wheel spacer does you will have faster wear and there isn’t a way around it nor is there a timeline of how much faster. If you wanna run spacers for whatever reason, then do so. Just know that every side affect regarding maintenance is an adverse side effect.

 

Understood you move wheel farther out the bearing wasnt made for the wheel to be that far out.

OK what about alignment have you any bad wear patterns because of the spacer ?

 

Noticed there was a thread where someone linked a BBK by StopTech that fit 16 in wheels but the link is broken.

At the bottom of this page there is a link to template of how to check clearance on 16 in wheel if the StopTech 6 piston caliper will fit. Which makes me wonder IF a StopTech 6 piston caliper fits 16 in wheels then could just buy that but get the 338 mm rotors and pads somewhere else to save money. Since mouting point of caliper is a constant if they truly make a caliper that fits 16 in wheels then the other parts would not need to be StopTech just the caliper.
Any other brands that make a BBK caliper that claims to fit 16 in wheels ??

I said i want sharks with freakin lasers attached to the tops of their heads is that too much to ask ??

 

I've used them on my Ram150 with Viper Style wheels for the last 20 plus years without issue. I have them on most of my cars to get the look just right.

 

5th gen 4Runner pads are the same as 2nd/3rd gen Taco. They just work on a larger radius (more leverage) and develop more clamping force from the larger pistons, at the expense of greater pedal travel and really shitty pedal feel.

Whether 1.25" or 1.5" spacers will work depends on your starting point. If you have stock +30mm wheels, 1.5" spacer changes the effective offset to -8mm, not enough to clear the larger calipers.

 

I have SpiderTrax to stop rubbing my frame. That I wouldn’t have gotten had I originally ordered my Method wheels in better dimensions had I known.

people have success with good brands like SpiderTrax and bora.

that being said I’ve never heard of spacers for calipers.
I’m under the impression all you need to clear larger 4runner calipers is a 17” wheel.
Not to mention the fact that 4runner calipers come stock on 4runner calipers that do not come stock with spacers and probably nor different special wheels.
It is not an enormous jump.

 

Whole reason i even researching wheel spacers is because i wanted to put on larger caliper and rotor and not have to change from 16 in wheels to 17 in wheels which would also mean getting new tires which my tires are pretty new.

 

These are my stock 16 in wheels. I have no idea if they're +30 or what exactly. Not sure what these wheels are called either but they have a lip kind of in middle of them instead of being completely flat on the inside.
I will go measure how much space i have now with my stock calipers on. 4Runner calipers i would expect to stick out closer to the wheel though otherwise how would the 4Runner caliper be able to use a bigger rotor ?

 

in that case I’d recommend you ask in the 4runner BBK or research
If 4Runner calipers is the way you plan on going

if spacers clear it
I’m under the assumption 16” to 17” is to change the diameter to clear and not width/offset but not 100% sure the reality.

if that is the case, new tires can be sold. Wheels can be sold.
#1 you can still run regular brakes or semi upgraded for now.
I am still on stock calipers with added weight and 35’s. It’s not the best but it works.

never mind. Those wheels. Lauffen tires?
But talking about bigger brakes
With small tires

Not sure about that.

those are not clear a brake wheels.
And those are I don’t care about my life tires.

 

The 4Runner rotor is 3/4" larger diameter or 3/8" radius growth, so expect the caliper to be at least 3/8" taller. You can tape some pieces of wood or plastic 3/8" thick to your existing caliper for mock-up, and see how far outward you need to pull the wheel to fit.

Why do you feel you need bigger brakes? Are you planning to run 35" tires? Tow 3500 lb unbraked trailer?

 

While the clearance right now with stock calipers is close its closest where the lip is closer to the spokes of the wheel.

I think this is why one member said he could have used 1.25 in wheel spacers and been ok because the outside of the caliper gets close to the lip near the spokes.

However on the back side at the bottom and top of the caliper there is maybe 3/8 in space. On the front side there looks to be about only 1/4 in space between the lip of the wheel and the caliper though.
Might just try to fit one on and if it doesn't work return it. Even if fit was not perfect I wonder if the caliper could be grinded on to make it fit.

 

What braking issue are you trying to solve?

For singular hard/panic stops, once you kick in ABS tire grip is what stops the vehicle, and bigger brakes don't really matter.

They can matter in other braking scenarios, mostly ones that create a lot of heat.

 

Just do the Stoptech brake and rotor upgrade and call it a day. Putting on the 4Runner upgrade isn’t gonna magically stop the truck 30/40 ft shorter.

 

I want to stop faster i did big brake mod on another vehicle and it stops so much faster of course the rotor surface area increased alot and went from a 2 piston caliper to 2 piston calipers but it greatly improved braking performance.
Have a 4 door full cab V6 Prerunner and 6 Ft bed, its way under-braked compared to have big the truck is. I mean seriously that like asking someone installing a supercharger what power issue are you trying to solve?
Why does anybody modify anything because they want it to work better. Why did all you guys put on monster truck 35 in tires on ? Rhetorical
Looking for ways to make this work does it matter why i want to do it ?
Only way it seems to make it work so far is 17 in wheels or wheel spacers any other method I just have to try to make work.

 

Do you mean the StopTech 6 piston caliper, 323 mm rotor kit that someone else linked in the other thread because that link is broken. Also I dont know why someone would not just install 338 mm 4Runner rotor and use the Stop Tech 6 piston caliper. If you can fit a 6 piston caliper in there why not use a 338 mm rotor too ??
StopTech it appears wont just sell the 6 piston caliper since its sold as a kit.

 

First of all, 35s are mainstream now, with all three domestic OEMs offering it as optional stock size (Bronco Sasquatch, Jeep Rubicon X, Chevy Colorado ZR2 Bison)

Your stock brakes have more than enough clamping power to lock up all four tires, so stopping distance is limited by tire grip. Upgrade those Laufens first.

A 5th gen 4Runner's GVWR is almost 1000lb heavier than yours; that's the reason for the 4Runner's bigger brakes.
