I have no experance with traction control but I have been watching the prices and seems like the rears with traction control sell for less then the ones without. Any reason I can not put a traction control rear in a NO traction control car? I was just guessing but the traction control would just measure the speed of the differential, meaning its just a sensor?

I may be making a run to this place this month so shipping would be free

 

Traction control rears use sensors at each wheel. A non traction control car should be able to work with a traction control rear without any problems, as long as all mounting brackets are the same.

 

if there is a mount for the center sensor and i think there is then it should work. u will need to mount the reluctor on the ring gear.

 

I forgot to mention, that if you currently have ABS, there are two versions. The old 3 channel system uses a sensor at the differential housing, and the newer 4 channel system uses sesnsors at the wheels. So if you don't have ABS any axle that fits will work, but if you have ABS and want to keep it, you need an axle that has the ABS sensors in the same location as your current axle. ABS and TCS share the same sensors.

 

Any idea what year they changed? I would like to keep my ABS.

 

You need to get under the car and look at the rear axle. If you have sensor cables going to each rear wheel, you have the newer set up. If you have a single sensor cable going to the differential, you have the older set up.

 

also is you have the individual wheel version the abs is 4 channel so had each individual wheel with separate brake lines, but the 3 channel has 2 to each of front and one to the rear then split. So you might have to transfer over your brake lines too.

Also about the sensors, there was another guy who posted that he swapped from the middle to each wheel and wired them up same colours and everything but it still put the ABS light on cause the re-circulating rings are different somehow. You might have to adapt the axle to suit your car, id sensor in middle or not, but this means a diff unit swap too

 

99 was the first year with the new ABS system. 94-98 all were the same, 99-02 were the same. No idea why they didnt change them when they changed everything else, but some reason they waited a year. Hope this helps!

 

That would mean that a 98 Z without traction control would be a direct bolt in and have the Larger LS back rotors brakes?

 

Not quite sure on that. I know the abs controller/pump is different for 99-02. 93-98 was different. I could be wrong, but it would only make sense that the controller was changed because the abs system changed.
