If you are thinking of changing out your sway bar i would sugest you uprgrade your shocks and springs first. Stiffer bars need stiffer suspension.

Well I put a ws6 sway bar on my regular T/A so now I'm just going to put the one I took off on my v6.

since its the front bar you will be fine but upgrade your shocks and springs if you want to put a bar bigger than 19mm on the rear, if you dont you will be looking for trouble.

What are the sizes for the rear?

I believe we have 15 and the v8's have 19's but early 1le cars got 21mm.

Here's a link that some may find helpful.

yup, i have had that site as one of my favorites for a while now great info. Nothing really pertinent to what is safe to run with stock v6 shocks and springs unfortunately. If you plan on upgrading your shocks and springs deffinately read that over and also i would check out www.frrax.com as well.

from personal experience a 30/19 mm setup on a stock suspensioned v6 is leaning on the oversteer side, I kind of enjoy it, been taking it through some turns hard and such.

But I coudl see some people prefering less oversteer. Might reccomend 30/17mm setup. Or a 32/19 setup. on a v6.

17mm was found on older v6s rear bars.


Either way I definitely suggest throwing at least a 30mm in the front bar, helps alot with the understeer issues 28mm front bar cars have.


I am sure some will disagree with me and i guess it varies to how people like to drive, but its what I enjoy.

OK. :D

30/19 on stock springs is way too much oversteer. It's not a question of how you like to drive. Oversteer ain't fast. The rear wheels need some excess traction to put the power down coming out of a curve. And, in some circumstances (like rain) it's downright dangerous.

32/19 is really not different. On the front the improved camber control keeps the front stuck while the back is still loose.

On a 98+ changing the rear from 15 to 17 is a big change. I simply don't know if it's OK. Changing from 15 to 19 is a huge change that unbalances the car.

Tire selection should actually be considered when thinking about swaybars. Rear swaybar size setups depend on traction available... what works with regular street tires won't work that well with really sticky street/race tires because the added traction counter affects the bar change too much.

Big as you can front sway won't hurt (35mm hollow is good) as the front suspension has very little compression to begin with - so limiting the body roll as much as posible will help out. Rear selection is more dependent on traction available and how sensitive you are to what the car is doing. The larger you go with the rear bars, the more rear traction you need along with quicker yet smoother steering ability. The good thing about bigger rear bars is the faster handling response you have. It can also be a bad thing since the car is now that much more sensitive.

Personally, I feel the huge front and rear bar setup with stock springs works fine for me and and if a mistake is made I know it really quickly. Can't imagine my Camaro being happy with a "dinky" 32mm/19mm setup. It would be too sluggish for autocross/track duty and start crying because it was handicapped! [img]tongue.gif[/img]

With 275s in the rear a 19mm bar is flat out needed imo... its a little tail happy on 245s but its at the point where I like it. Personally on a tight autocross course where most of us will be racing I think its nice.

Either way ANYTHING over a 15mm rear, my car was a freaking understeering snow plow.


As for dangerous in the rain, I have been in worse rain then most have you have ever seen, on some pretty bald tires, and it wasn't "dangerous" I mean granted with better tires I coudl have stuck better but its not like a take a turn at normal speeds and start flying into the ditch doing 360s.
