5 lug conversion

trlprk · Mar 22, 2011

Hey guys, I want to do a 5 lug conversion on my 91 notch. A local salvage yard here has a 94 GT. I know to get the spindles, hubs, calipers, and booster. Should I also get the M/C? I will using ranger axles and drums. What else should I grab while I'm there? And what else should I get

Only grab the mc if you plan on running rear disks. You don't even really need to change the booster.

If onenday down the road you want rear disk....grab them and squirrel them away

My car is an ex 4cyl car with the 4cyl brakes. I am trying to weigh the cost of 5 lug axles and drums vs the cost of the complete rear end. He wants 300 for the whole rear end. If the gear ratio is like 3.08, I'd have to swap gears too....maybe worth it for the brakes.

if your car still has the 7.5 rear grab the sn rear. When you install the drum backing plates it will bring your axle width back to stock fox. Use your drum brakes with ranger drums from the auto store and you're all set.

My car has the 8.8 . So, I grab the 94 rear, use the axles. And transfer my drum backing plates and get ranger drums? I can then squirrell away the disc brake stuff like Mustang5l5 said for a later date. Sounds good to me. With my car having 4cyl booster, should I grab the '94 booster also? What other things do I need to do the swap? prop valve, hard lines, brackets? Ive read the 5 lug thread, but it gives me a popsicle headache with all the info.

If it doesn't cost to much you may want to take the emergency brake handle set up. if you ever go to disc in the rear it will save you the hassle of modifying yours. If there cheap take the cables and brackets also.
just a thought

Not sure if this link has been posted here. It has all of the information you will need, it has helped point me in the right direction before I changed the build completly.

thanks, thats some good info there. And no headache!

The guy wants 475 for the loaded spindles (spindles, hubs, calipers, rotors, and lines), and the complete rear end. The car has just under 100k on it, so there is a good chance the calipers, and possibly the rotors will be usable. I will see if he can throw in the M/C, booster, ebrake handle and cables for a little more. Even if some of the stuff needs replacing, I'll save on core charges.

I would honestly pass on those Front Calipers, they are Steel Single Piston on not much better than stock, just buy some 99-04 Aluminum Dual Piston PBRs. Modifying the Handbrake is no big deal, you cut the Spring and weld the Pawl.

I agreem but in the meantime i'd grab them anyway.

If he decided to go with the 99-04 calipers, he should really use a 1.0" 1993 CObra MC anyway.

If the car doesn't have ABS....take the fitting from the prop valve on the rear (that points to back of car) and the brake line that runs to the front driver's side wheel as well off...

makes a VERY easy 3-2 conversion with those parts

I agree they aint the best, but it gets me in the 5-lug door the right way on the cheap. Anything short of 4 wheel manual drums stop better than this car does right now. I can get the better cobra brakes down the road.

Im not sure if the car has ABS. He has two in the yard, I will check when I'm there

If i'm not mistaken 94-up came standard with ABS.

Mustang5L5 - I have 5-lug conversion question for you. I have all the brakes off of a 96 Cobra(13" fronts and 11.65" rears). Will 93 Cobra booster and MC be enough for it or should I use 94+ booster and MC?

Mustang5L5 · Mar 23, 2011

Booster is the same...get whichever booster you want...1993 cobra or 1994-1995 booster. Difference is stud pattern. 1993 cobra slightly easier to install...but not much

As for mc....of they are the 1996 cobra 38mm calipers, you want to use the 94-95 cobra 15/16" mc. The 1993 cobra 1.00" mc will give you a slightly firm feel and it might be tough to apply the brakes well with cold brake pads

Ok, Thanks! I'll be looking get the 94-95 Cobra mc. As for the booster I'll go ahead and get the 93 Cobra booster because all I'll have to do is enlarge the holes for the studs that go thru the firewall rather than drill a new hole.

Make sure you pick upmthe correct 3-2 conversion kit for the cobra mc from max motorsports.

Ok, thanks for that tip. I figured LMR had everything I needed.
