Will aftermarket caliper brackets ... the kind you use with modified spindles........work with actual NOS 1LE spindles ?

Hole in the bracket right size ?

Anybody know the thread size on the factory 1LE spindle caliper bracket holes ?

Thanks..........

 

My understanding is that the factory 1LE spindles are tapped for an M12 bolt. I have never actually had one to measure for myself. So an aftermarket bracket will fit if it is designed for that size bolt. That will depend on the supplier of bracket and the kit it is intended for.

Either way you can either drill out the hole in the bracket if there is sufficient meat or drill and tap the spindle to a larger size if needed.

What are you thinking about?

 

Well the factory modified spindles don't have the bosses around the holes so I am thinking the bracket for modified spindles would be too thick ? Am I missing something ?

See attached pic.................

 

It sure does have the bosses. 90-92 on the left, 82-89 on the right. Keep in mind both of these have been modified to different extents.

 

Sure does.............thanks much and forgive my stupidity.

No reason the aftermarket brackets won't work then.

 

No worries, I have been looking at these for a long time.

What are you thinking? I seemed to recall you were advocating OEM brakes for most cases. Do you have a set of 1LE spindles?

The top hole should be 10mm 1.5 pitch. Bottom hole 12mm 1.75 pitch. they are the sizes listed on the original blue prints for the spindles, I assume they remained the same through the years.

 

Well logically then the holes are different diameter in the factory brackets.
Spohn says their brackets will work with a factory 1LE spindle but their
holes are the same diameter unless I am mistaken.

Don't want any slop in the bracket holes.

 

So do you have a set of 1LE spindles? If so, just measure the holes. Once you have the holes measured, you can always have a bracket made if a suitable off the shelf solution is not available.

No don't have the spindles but can get them.
Trying to decide if the expense of factory 1LE spindles is
worth it and what I would have to do with the aftermarket kits to make it work with the NOS 1LE spindles.................................

 

Well the 1LE is OEM and since the car has 9k on it they would be perfect.

But no I have laughed myself silly at those wanting to put exotic 4-6 piston calipers and rotors requiring 20 inch wheels on a 250- possibly 300 hp vehicle.

To each his own but the only thing on here dumber would be wanting to put the cluster**** ABS on our cars.........lol

 

There are a lot of different aftermarket kits out there that use a bunch of different fastening sizes. Unfortunately you will likely have to be very specific on what kits from which manufacturer you are looking at. It would be best to ask the manufacturer.

With that said, if Phil is correct, and the top bolt is 10mm, then even if I had a 1LE spindle, I would drill out the upper hole to 12mm. There is no reason other than possibly packaging to have the two holes different sizes.

Whether the 1LE spindles are worth it or not of course depends on how much they cost and how much your time is worth, and whether you have the tools to modify a normal spindle.

What are the plans for this car? The 1LE brakes have a VERY different feel than OEM. I seemed to called you like the feel of the OEM brakes.

 

Why you keep insisting I like the OEM brakes is beyond me .. never said that.

1le was a factory option so I don't consider it a mistake adding it to this car.


No way these 4-6 piston calipers options are in the 6-700 hundred dollar range.
Wilwoods are gonna be 1500 or in that range.

Stupid just like ABS on these cars. Road racing brakes are exotic. Joe six pack doesn't need em. 500 horse Mustang sure does. Our cars don't.

Not here to make friends and will always tell it like it is.

Don't care who doesn't like it..........

However I do appreciate the info but keep your advice about whether I think exotic braking systems or ABS are stupid because most here will agree with me.

Its there vehicle but its ridiculous...........

 

As I said, I don't have time for an argument. With that said, there is nothing exotic about a Wilwood 4 piston kit that costs under $1k shipped to put together. The Spohn kit you were referring to is $850 and doesn't include shipping, spindles, spindle modification. The cost is comparable.

I will keep my advice to myself by no longer taking time out of my busy day (day job, night school, small business) to help you. Nah... I won't do that, I am to nice of a guy. What is the point of knowledge if you keep it to yourself. Some people just need to learn the hard way, I get that, I am the same way sometimes.

The Spohn bracket you were referring to seems to be sized for a 7/16" bolt. So neither the 10mm or 12mm 1LE spindle thread size is particularly correct.

Buying 1LE spindles to modify for aftermarket brakes seems redundent, and a little wrong.


If you are buying aftermarket brakes, mod the stock spindles.

Sell the 1LE spindles to someone that wants 1LE brakes.

 

Stingy...

 

I have sent many upgraded kits to guys with 1LE spindles and none have failed to bolt right on with M12`s at both locations. I have also had OE 1LE spindles in for upgrades too and they have always been M12 top and bottom.
The 1LE spindles are no different than any other 3rd gen spindle, the factory modified regular spindles to create 1LE brakes. If you could use the 1LE`s without modding them and bolt the brackets right on, I`d use them if no mods are needed (like steer stop removal)
All of the brackets I offer use the M12 bolt to attach btw.
