I own a 91' RS and was thinking of upgrading the stock sway bars but am not sure how much of an improvement I will get.

 

Well, according to this I think we have a 34MM front and 21mm rear, or a 36mm front and a 24mm rear. I don't think you can upgrade much more from a 36mm, and I woudl imagine the differance between the 34 and 36 wouldn't be too substantial. Although, I saw a wrecked iroc at a bodyshop, i know the guy who owns it, he said it was going to the junkyard in about half an hour, so i pulled the sway bars and wonderbar. So ill find out what the differance is sometime soon BTW, I have a 91Rs too.

RS sway bars are stupid small unless ofcourse you have the suspension package or something. But anyways they make a huge difference. I just threw some ST sway bars on my car and the difference is night and day.

 

ST?

 

ST = Suspension Techniques

 

May I ask, how much of a differance will an ST swaybar make over a 36mm hollow iroc bar?

 

id like to know tooo

 

If you have the 16 inch wheels, which includes the suspension package on your RS I would say it's not worth it, but if you have 15's it will definitely be an improvement.

 

I've got the 16" wheels. Do I have the same swaybars as an IROC/WS6/Z28?

 

So basically an rs with 16in wheels has a 36mm bar in it already?

 

It has at the minimum a 34 mm bar up front.

 

the 34mm solid bar and 36mm hollow bar have the same effectiveness. but the 36mm has a weight advantage over the 34mm because the 36mm is hollow
