5 Lug upgrade issue

Blueinfan · Oct 23, 2021

Hi All,

We’ll hit a snag on this 5 lug project. Purchased this 5lug upgrade from eBay n got ripped off. Parts missing, n nothing fits.

I installed the caliper bracket but the drum is hitting the bracket.

Rear n front calipers are UPR,
SN95 spindles . I have attached a pic of what was in the upgrade.

First off, factory SN95 brackets (what you have) and stock SN95 rotors don't work with Fox length axles. Some form of modification is needed or different rotors.

For the components you have the simplest solution would be to cut the mount bracket and install on back side of axle flange.

Alright as many of you know, an SN95's axles are 3/4 of an inch longer than fox length axles. So, this puts the brake location out farther. Most people just go out and buy special bracket kits to make fox length axles work with SN brakes. Well I decided not to do this. Here's what I did: I...

my car is a 1991 Mustang LX convertible 5.0 with 8.8.

Is there another n easier solution besides cutting the bracket? I don’t have the tools to cut the bracket.

What other option can I do?
I thought the kit I bought was straight n simple. I guess I was wrong.

The other solution would be to get some 94-98 rear axles. They are .75" longer, fit in a fox axle housing and the brakes will work as they are.

Will these work? Will it impact my rims at all?

Those would be the correct length. Yes, they will move your wheels out .75" further. Did you have wheels already or still need to purchase them?

I bought these as rollers until she’s ready. I might go with bullitts orthese Cosmis

I used the North Race Car brackets with the same calipers you have, and Fox length axles, with the SN95 flange.
Looks like your axles may be SN95 flange, so I think you would just need the different brackets. You have to measure that flange on the axle to be sure.

Angle grinder and a cut off disc. Could get them from HF for under $50. Not bad considering you were about to spend $225 on other axles. And then you add to your tool collection.

Then go the the thread I shared the link for. Go to the last post, it has revised cut lines that keep all 4 bolts (if that is the concern).

The SN95 axles will work fine with the cobra wheels, but the fox lenght axles will be needed for the cosmis wheels.

These are the offset brackets you need to run the fox lenght axles in the kit.

You should be able to sell those SN95 GT/V6 brackets on eBay.

Kinda crappy for the seller to sell you the wrong axles and brackets in a kit

After the car is up an running, I will be selling anything left over.

I told the dude that I was going to contact PayPal n eBay for selling incomplete sets on eBay. Ripping people off n providing incomplete info.
