I am almost done with the 5 lug disc brake upgrade on my new 91'. I have 94-95 front spindles, Northracecars PBR calipers and 13" front rotors. I think I have 95 Cobra R rims and now they don't fit. How can I make this work?

P.S. I have had these rims for years on a basic 5 lug drum conversion.

Can you explain how they do not fit? Are they hitting something? Are they 17 inch rims?

Likely the .75 wider track width on the sn95 spindle pushing wheels out. Cheapest solution may be to put a set of 1 inch shorter arms on it. UPR makes them that are pretty reasonable.

They will change strut angle when you do that which will limit castor. On a street car you will still be able to get it right as long as you have camber castor plates.

They are 17x9 rims that fit well with the old 5 lug Lincoln rotors. With the new 94-95 spindles the tire and rim is wobbeling and won't seat against the rotor by about 1/8" i would guess

I need to know what you mean by doesn't fit? I have the same exact setup including the rims and everything fits perfect.

Do you have hub centric spacers in the wheel? Plastic rings, to align the wheel on some model car? Otherwise if the bolt holes line up, and they do... nothing that should be a problem in the center of the wheel.

Now I should think there isn't anything in a stock caliper package that's too large on those spindles and rotors to fit a 17" wheel.

Is it just the front that does this? Can you post a picture of the setup?

I was assuming this was an issue with hitting the fenders or sticking out...

My bad, I concur with the others, no reason it shouldn't fit.

I will be home shortly and take pics. I am not sure if I have hub centric centers. It does seem like an issue with the center hub. I will take pics and get em up soon. Thanks for your help!!

If all you changed was the actual brakes, that is your problem. SOunds like your new large calipers or caliper brackets are casuing a fitment issue.

Sounds like you have a problem with your rotors or spindles then. I have 94-95 spindles, 13 inch rotors, and 17x9 front wheels just fine.

Ok, Here are the pics on the rim and the tire on the car. The wrench in the middle represents how much space is between the back of the rim and the rotor.

Any ideas?

Never mind!! I'm an idiot..With a little force it went on….It has to be perfectly square on the threads and then pushed on with a little force to get it to seat on the rotor. I guess if the rim is not perfectly straight when putting it on it hangs up on the spindle hub.

Sorry for the trouble..Thanks for all your help and great responses!!!

No problem. Just glad it worked out.
