You are bolting these rotors to IFS hubs so you want the IFS rotor bolt pattern. IFS rotor will not work because they are too large in diameter. Vented SFA rotors off an FJ60 or SFA rotors of mini trucks will work after you drill the IFS rotor bolt pattern into them.

Reviving a very dead thread but I've picked up a set of 82 FJ60 rotors to do this with and the FJ rotors are about .5" larger in diameter then my IFS rotors...is that correct?

Yes I know that, Its SFA... I'm comparing them to the ifs rotors coming off my truck to drill the pattern to use the fj rotors with my ifs hubs on my solid axle to widen it

82 LC rotor's work fine. Drill the bolt pattern into the 82 lc rotor using a IFS rotor as a template. The ifs brake calipers will have to move to the outside of the knuckle it should line up with the 82 lc rotor once put together.
Make sure you use grade 8 bolts to bolt the caliper to the knuckle.
The only reason your using the IFS rotor as a template so you can drill the LC brake rotor so you can bolt it to the backside of the ifs hub body like the IFS rotor does.
Yes there is a size difference between the LC and ifs rotor. It will not line up correctly with the ifs rotor.
Meaning drop a ifs rotor next to a FJ rotor There is a height difference as well.
So this being said you will have no place to bolt your caliper to line them up.

Hi everyone. I'm new here. I was browsing the internet and got led to this site. You all have a bunch of information. I have a suzuki samurai with toyota axles. IFS rear and 85 front. I have a transfer case brake, and do not need breakes on the front axle. Make things simple, will thhe new hub go right on the old spindle with no mods? and what do we do about hubs. I was kinda confused in the original thread. thank you

The new IFS wheel hub will fit right on the 85 spindle
The 85 locking hub will also swap to the IFS hub.
If you're not using front brakes, you don't need to modify the rotor (or even install it?)
I can't imagine not using front brakes, so you're on your own there

Ok cool. thats what I needed to know.Thank you. and as far as brakes go here is a picture of what I'm working with :
A single t-case brake is all it needs. stops on a dime! doesn't see rode time. strictly a trailer rig to and from mudholes and the woods! Don't have to worry about fallin down a mountain either beins as I am in SW florida.
And for the record my DD is a 93' yota
Wanted to clarify before everyone though I was just a sami guy stealing the thread

Old thread I know.But I got the 84 fj40 rotors and I am having a hard time lining up the ifs rotors to used as a template.The hat on the fj's is a little bigger and none of the holes line up.I may just be dumb but how did everyone line it up to drill?I really dont want to drill the out of round.Thanks

I've got a solid axle with IFS wheel hubs, adding 1.5 inches to each side. I've got the FJ rotors and V6 calipers, but my question is, do I need solid axle hubs or IFS hubs, or will either work? I haven't really found a definitive answer
