Do these really exist?
Part Number?
Picture? Picture of bar being measured?
What year/ options required and cars did they come on?

I've heard people say these were a pontiac only part I've heard others say they were a 1le part, how about helping me get this straightened out once and for all.

 

no, later ws6 and z28 cars had 36/24 combo, same as 1LE. you can get a 25.4 mm from spohn

 

I know spoon offers a 25mm bar, but I am talking about the stock 25mm rear sway bar. Supposed to be very rare.

 

so rare, it doesnt exist

 

That came from the Tech Data Section, that's where I was getting the information from to begin with.

But I guess somebody could have easily hit the 5 key insted of the 4 key by accident. Understandandable, also did a search of the suspension form some people do claim to have a 25 mm stock rear sway bar, but I guess that too could just be incorrect measuring techniques. Anyway of closing this thread so that nobody need post about this issue again.

 

thats interesting, i had never seen that before. anybody have a 15th they would be willing to crawl under and measure to make absolutely sure. the mods would have to be the ones to close a thread, but im kinda curious now. i just remembered about a thread on the FAQ board that has all the sway bar info anyone could ever want, but it says nothing about a 25mm bar

I have the 34front/25rear Spohn combo on my car- but no I have never heard of a factory 25 rear bar.

 

I have heared from several sources that the 84 15th T/A came w/ a 25mm rear sway bar. Ive read this in vintage magazine articles/ reviews from 84, as well as the tech data on this site.

My 84 came w/ the 23mm rear bar. I will have to ask a friend of mine w/ a 15th to measure his.

 

Week-end Project maybe?

 

I always thought all 25mm (more commonly referred to as 1") bars were aftermarket and were more drag race oriented than handling performance. That's a big bar for the rear!
