Default Wheels for disc brakes

Hi Guys,
I am doing a disc brake conversion on my 60 bird with scarebird brackets, s-10 calipers and mustang rotors. I got wheels for a 1992 ranger that are 14" X 6" and they do not fit. They rub on the calipers. I thought about grinding some off of the calipers but decided against it.
So my question is what wheels actually work? I got the list from the technical library. Those of you that did this conversion with the scarebird brakets and used 14" wheels, what did you use?

That's strange. I've used the Ranger wheels with discs before. I don't remember if they were the S10 calipers though. I remember someone else having to grind some metal off of those calipers. It wasn't a big deal. There's plenty of metal on those calipers.

I agree with John. Either grind a bit off those castings or try a 1/2" spacer between your wheel and the hub. Tire stores that sell custom wheels should have them. I used them for over a decade on my Mustang. If they aren't for you, I'm sure they will take them back. So, call around.

It's awfully odd that your Ranger wheels don't fit because they were made for disk brakes. - Dave

See Daleo56 thread on disc brakes for his "Snowbird". That's the one John is referring to. He posted a close up pic of the altered calipers. You might want to PM him to see how much he took off, if you want to go that route. He's a great mechanic and seems always willing to help.

Default 14" rims

I found 14" rims for my 1960 Thunderbird at a used rim supplier in Spokane, WA. This supplier must have had 2,000 rims in his yard. He supplied snow rims for WA, and ID.

I think the difference is in the off set. It's not much but just enough to clear the calipers. The disc brakes make all the difference in the world to stop the 1960 Thunderbird.

Is there some way to tell what car the rims came off of by the rim? When things warm up I can get some pictures of the back side of the spare tire, and try to post them with help from Dave Dare. There might be pictures on the TRL. of the off set.
I think the rims I found came off of a Mustang that came with disc brakes.

Time for Notre Dame football.

Hi Bill

Looks like you are going the same route I did when I did the disc brake conversion. Good selection!!!

I have re-posted below the thread that I submitted after my conversion.
I know it won't help you much as to a wheel selection for your car but I had a similar case of the wheel rubbing the caliper. As you will see from my post, it required only a VERY small grind off the caliper to allow the wheels to fit perfectly.
As I said in the post, I only know that the wheels I got were marked as 14" Ford but did the job perfectly after the grind.

Good luck Bill

Hi Guys
Finally have the disc brake conversion completed & the bottom line is just amazing the difference a decent brake system makes. I actually feel safe knowing I now have such improved stopping power.

Just to summarize the components I used:

ABS 8" booster & dual m/c (disc/drum) ABS Stock No 9787, Item No 270556931229.
This booster/m/c is designed for the '59 TBird with a/con. It comes complete with the bracket & is set to the correct angle so it clears the a/c unit etc. It also has the extended pedal rod so basically is a straight "bolt on" item.

Scarebird brackets Part No GXY.

Scarebird also supplied GM-S10 loaded calipers & brake hoses to suit

Rock Auto supplied '68 Mustang rotors. Part No 397 6006R.

By using the Scarebird brackets & Mustang rotors, I retained the OEM spindles & bearings.

As I said in an earlier thread, I was lucky & found suitable 14" disc brake ready rims at a local tyre fitting shop but I have no idea what vehicle they were off. They were just marked as Ford 14". The rims just touched the top of the caliper but a VERY small grind to the caliper fixed the problem. Rims fit perfect & I was able to have my existing tyres fitted to the new rims. Nice cost saver there!!

Had two pipes made for the new M/C & fitted a mechanical brake light switch to the pedal.

I can't take credit for any of this work. It was all done by my mechanic mate. He usually does Mustangs & has done many disc brake conversions on them but this was his first go with a Thunderbird.
An excellent job too!!!!

My thanks to all the members who have helped me with this conversion & given me priceless information that pointed me in the right direction.
I know there are many threads on this site re disc brake conversion & so many options & I hope that the info I have supplied here might be of assistance to other members.
Thanks again guys

Default wheels for disc brakes

Thanks for the replies. It appears that the wheels I am trying to use have a 1 5/8" offset towards the inside. I tried putting washers on the lug bolts to move the wheel out 1/2". No go. So the offset is the problem. I will return them tomorrow and look for some with less offset. Is there any way to determine off set other that physically measuring the wheels? Maybe part number?

There are two very important factors in finding correct wheels, Back Spacing and the Inboard Safety Hump area. Let's refer to the picture below:

Your original 14" wheels have less than the minimum 3-1/2" Back Spacing but there is NO Inboard Safety Hump to accommodate a caliper11" because drums simply didn't need the hump.. This hump appeared with Granada/Versailles/Mustang disk brakes.

For new 14" wheels that work with S10 (Chevy) or S14 (GMC) calipers, go to and search for 'Wheels'.

On the left, click on:
Part Type / Wheels
Wheel Diameter / 14 in.
Wheel Bolt Pattern / 5 x 4 1/2 in.
Backspacing (in) / 3.5 in.
Wheel Width (in) / 6.0 in.

Then adjust the search to show Price, low to high. These prices include shipping to your house. If you have any technical questions, call their Tech Support Team.

Leonard Wheeler recently purchased new wheels from Summit for his Scarebird front disk brake retrofit. He said his new calipers hit the wheels but he ground off very little from the caliper casting to make them fit perfectly. He's running with 205-75R14 tires. - Dave

Default Wheels for disc brakes

This specific information has been posted in the TRL under the Disc Brake Conversion section. Thank you very much for posting this, Dave! It should certainly answer a lot of questions regarding the set up of these 14" disc brake ready rims vs the OEM ones.
