Camo method doesn't require you to remove the rotor tho. And either way you gotta take off the caliper. I see no real world reason to do the taco brakes. I've done them for a buddy and they are smaller when comparing to a ifs truck. Even the 4 cyl calipers are. It is nice tho if you want to take the spindle off for some reason. I never touch those bolts tho. I always remove the knuckle as an assembly.

best part of the taco brakes and the FROR brackets is being able to remove the spindle/wheel bearings/hub assembly as a "unit-bearing" of sorts to get to broken axles/birfs, never touching wheel bearings or trunions.

While that is semi true (you don't have to mess with wheel bearings doing camo method) It can be argued that way is harder and takes more time and is more.likely to damage a gasket, at the spindle. To each their own.

There is a company who makes steel 15" wheels just to clear on tacomas, but I cannot remember their name. Only had 1 customer come in to see if I could get them and that was a couple years ago.

Wheeler's Offroad, and it seems they no longer make them.

My tacoma as well as many of the ones when I was in highscool ran regular 15x10 or 15x8 steel wheels with 3.5" back space with no problem?

I'm going to 17s so its not a question of diameter clearance but rather the caliper body clearing the section of the wheel near the wms. Where the rim tapers in to meet the hub.

Tacoma brakes are smaller than 4cly ifs and v6 ifs. So id imagine they would be easier to fit wheels on. My buddy with a 98 is also running some 15s right now.

redneckcustoms13 · « **Reply #37 on:** Jan 04, 2016, 09:06:07 AM »

Andrew I would think most any steel wheel wouldhave the taper your looking for. I know what youe concern is I had a set of 15"aluminum eagle alloys that I put on my tacoma and it bolted up bur wouldn't spin, the caliper face was hitting the wms of the wheel. It was virtually flat so even the slightest taper would have corrected it. I put a 1/8" spacer behind it, ran it for a while with no issues.

Are they really now? I assumed they were bigger.

Sparkplug · « **Reply #39 on:** Jan 04, 2016, 10:55:01 AM »

Yeah. Pretty damn sure. Again I could be wrong. But I remember the 4 cyl calipers being larger. The v6 calipers for picups are massive compared to 4cyl. I'm not sure about the rotor. I wanna say is itself smaller also. This is all going from memory. So don't be taking this as fact. But I'm pretty sure.

SKULLYOTA · « **Reply #40 on:** Jan 04, 2016, 10:57:16 AM »

came up on Pirate again, more folks saying the taco rotors are smaller diamter....

http://www.pirate4x4.com/forum/toyota-truck-4runner/2228097-lets-talk-big-brakes.html

Does anyone know if the T100 calipers are bigger than regular V6 calipers? The T100 master is bigger than the V6/FJ80 ones....maybe T100 stuff is the way to go?

edit: T100 rotors are 25mm thick...maybe the calipers wont work.

I'm going to reach out to 4WParts and see if they will do a custom backspacing for me.

I am running the 86 IFS calipers on the fj rotors with 1.25" wheel spacers clearing a 15" steel wheel. on the rear with the tacoma rotors I had to run 1/4" wheel spacer or I could have shaved the side of the caliper some to clear the wheel. I am going to be doing the Tacoma slip on rotor for the front this week. I've had some IFS hubs and 99 4runner rotors laying around. also spun a race in a solid axle hub so I need to replace it any how. I'll let you know how it turns out it you havent done yours yet

What backspacing are your wheels?

FROR brackets, 02 Tacoma calipers and rotors, IFS wheel bearing that were machined on my lathe fit my 15" Ultra 50 wheels. If I had 17" wheels I would have gone with the same set-up off a 96 and up 4runner because the calipers and rotors are bigger.

There are two different kinds of rotors you can get for the 4runner. I just hopped on rock auto's page and compared part numbers between the two. there is an option of a 4runner rotor for a 15 inch wheel 297mm ( which is the same rotor as the only option for the Taco) then 4runner also has an option for a 16" wheel 319mm which was not an option for the Taco so you can use 4runner rotors if you select the 15" wheel option. I am finally starting on my hub swap today

I believe i am 3.5" back spacing, I am not sure if I will have the same issue up front but I will report back later today

Crawlin85 · « **Reply #46 on:** Jan 24, 2016, 06:56:22 PM »

Ok so I have a 4" back spaced wheels. I am using the same IFS calipers I had with my fj rotor swap. I do have to grind down the caliper for the wheel to bolt on, or get 1/4" spacers but I don't want to do that. I think the Tacoma calipers are the only ones low profile enough to clear the wheel. I don't think it matters what backspacing you have, I don't think steel wheels go from the hub out to the rim at a steep enough angle to clear IFS calipers so go with the taco calipers if you can. I also decided to tap my calipers so I would not have to try to squeeze a nut between the caliper and rotor. I did M14 but it thinned out the ears on the knuckle quite a bit so if you tap yours I would do a m13 to keep as much material on there as possible. Kinda wish I went with front ranges taco caliper mounting bracket but I don't have the money and I think this should work fine. Hoping to have it all finished tomorrow

Tapping the caliper seems very sketch to me. The knuckle material is much better for threads than the caliper. I don't believe any calipers on the market are threaded. I've never seen one. Just my 2 cents.

there was alot of material on it and I think its cast? like the knuckles. I read others tapping them, but I figured Id to some good hard test braking and see what happens and if it fails Ill go with FROR bracket. I haven't finished it yet, a caliper is sticking so I had to get a replacement. Everything else hasn't been too bad but I would dish out the $99 on the brackets I think I'f I had to do it again. I think it would be better than drilling and tapping, I'm just pretty strapped for cash and I thought it was weird that it bolts on with the spindle

Sparkplug · « **Reply #51 on:** Jan 27, 2016, 12:28:15 AM »

It's probably fine. I just haven't seen it done stock so I'm thinking there is a reason behind it. Granted I've never seen a bolt with a nut holding a caliper on either stock. Which is what I run. So I can't really say anything. I'm pretty sure the calipers aren't the same material as the knuckles. But they do have threads for holding themselves together. So obviously the material is good enough for that. Your probably fine.

Mudder · « **Reply #52 on:** Feb 09, 2016, 04:47:10 PM »

Figured I'd post what I'm running, ifs hubs on my 84 with v6 calipers drilled out to fit a 1/2" bolt with the knuckles drilled out to fit a 1/2" grade 8 bolt as well. I'm running the vented rotors from an 82 Land Cruiser with the holes drilled for the 6 back bolts and ifs hubs from an 89. When I went to put the caliper on I knew I'd have to take off some metal from the caliper mounting ears to get it back to being in the correct spot. I took a guess and took of .2000" of an inch and it is the perfect amount. I also had to grind down the pad where the squealers are (the one closest to the tire). Then I installed 1/4" spacers and took the truck for a test drive. The rims I have still hit the calipers with the 1/4" spacer on but it wasn't by much so i let it work it's self into fitting correctly.

SqWADoosh · « **Reply #53 on:** Mar 23, 2016, 11:16:37 AM »

Bringing this back again. I ended up sticking with 15" wheels. I just purchased the front range bracket for running taco rotors and calipers. I've got my machinist neighbor setup to mill down the hubs. The unknown for me right now is what to do about this banjo brake fitting I need for the tacoma calipers? What did yall run?

I figured out a route to take. I am going with 3rd gen 4Runner calipers instead of Tacoma. They have the regular fitting rather than the banjo and have a 15" wheel offering.

My next question has to do with the use of bearings and such when doing the IFS hub swap. Am I re-using my straight axle hub's bearings or do I need to buy IFS bearings? What should I expect there?

I guess I don't understand how all the innards can be the same with the extra width on the hub...

Hub width is the same. The flange where the lug studs mount is in a different location if I remember correctly.
