How good is a 90 Jag XJ Series 4 door as donor for front/rear suspension?

From reading this forum, I know that some of the members are very knowledgeable about Jags, and I have read posts about suspension swaps for mid to late 80’s Jags. I saw a 90 Model in a salvage yard and will be heading there soon with a tape measure and caliper to check things out. So far I have discovered that the 90-94 model seems to be different than earlier models with a 4.0 V6. I know that the older cars have a 63” wide suspension which should work for whichever one of my two antiques I am thinking about building. Would this car be posi? Gears? 90-94 suspension width? Swaybars? Is it still rear steer? Will the ABS brakes work okay in a non-ABS application? Are the hubs any smaller allowing modern wheels like Torque Thrust II with Vette/Camao offsets? Or will the hubs have to be ground down? Is this a good car to work with or are the 89 and older cars better? If so, how? How much are the suspensions worth?

Ask Zman. He knows.
He knows about flashlights, too.

 

88 was the change over to the newer stuff. the newer rears have out board brakes and mount different. dont know much about using the front suspension.

 

Great, if you're building a street rod.

 

are the newer rears still IRS units and modular?

 

Yes they are. I drive a 1993 Black with black leather as a daily driver. One of the best handling and reliable cars I have ever owned.

 

Did you just call a Jag... Reliable? (sorry, my prejudice comes from working on them)



Cadvettestang - what are you thinking about putting it in?

 

What size are your brake rotors?

What is the diameter of your front sway bar? Does it use a rear sway bar?

Will I need standard or metric tools to pull the cage and sub frame?

Will I need 1/2" drive large size sockets and long extensions to reach through the cage from the bottom or is there access from the side/front/rear? (I may have to buy tools to pull them)

 

I have been looking to make a resto rod from one of the following: 51 Ford Pickup, 48 Chevy 3500 Pickup, 55 Pontiac station wagon, 62 Cadillac Ambulance, 73 Mach 1 Mustang, or 68 Coupe Deville. I am looking at buying at least one of these cars soon, and have a deal pending on the Mustang.

Whichever car or truck I get, it will be powered by a Caddy 500 with a modern cam grind that is slightly above stock giving it a bump in power and fuel economy. I have a 472 and a 500 in my garage now.

All three of my project cars have been stolen in the past year. 72 fastback (Mach 1 clone) w Cadyy 500 and 12” GM brakes, 82 Eldorado with 472 and unfinished pro touring suspension, my first car, a 70 Eldorado that I raced in the 1985, and 86 autocross beating all of the older Mustangs, Trans Ams and Camaros.

I prefer Corvette C4 suspension, but I can get the Jag suspension cheap and it looks easier to install and set up. I just don’t know how well it will handle compared to the Jag suspension

 

lol... not the newer ones for me.

I've only used the 70's-early 80's ones. The newer ones haven't fit anything I was trying to do. No Dana center section on the rear.
