How big in mm ? is the ss/ws6 bar much stiffer? Looking for a cheap way to lose some lean.

usually its 30mm front and 19 out back, if its a 1LE option car it will be 32mm front and 21 out back.

It's my understanding that the 21mm 1LE bar was only available one year 1993, and that was because those cars used a lighter spring rate in the rear.

9T8W66, you could be right im not 100% on that. Remindes me of when i put a strano 35mm up front and a 21 1LE out back and man did it make a difference.

anyone know if the ss sway bar will be noticeable over the stock z28 one?

If its a 32mm front sway bar yes it will be, i forgot the percentages its been a while but just by going up 2mm makes a big difference so no doubt. If you can id wait a bit longer and get the strano 35mm front sway bar with a 22 out back, it will make a huge difference and without a doubt you will feel your car turn in much better into a corner and corner much flatter meaning you feel like your car is using the most amount of tire to the road. It also feels like it cant wait to jump into a corner. I had a 32 on mine and going from a 30 to 32 and then 35 was a big jump and was easily in the top 2 best mods i did to my suspension on my 93Z.

I woudl consider the aftermarket but a stock ss/ws6 bar is around $30. an aftermarket bar is $300 + . If I'm going to notice any difference with an ss bar I think its worth it.

I did it on my 01Z. Went to a 32mm front while keeping the stock rear and added poly bushings front and back...a very noticeable difference for about $100 for the bar and bushings, much flatter in the turns. It's not a strano setup by far but way better than a 30mm especially when you add the poly's.

21 in the back for 98-99 after that all have 19's

No, no, no...

ONLY 1993 1LE's and 01-02 SLP built 1LE's had 21mm rears, along with cars with the SLP Bilstein Ultra Suspension (not many). The '93 cars had a 32mm front bar, the others had a hollow 35mm.

1994-1999 1LE's were 32/19 just like any old SS or WS6.

Also, poly bushings do NOT make the bar stiffer. They can and do make the bar react more quickly, but they do not make the steel bar any more resistant to twisting (which is how bars work).
