So just out of curiosity, what is the largest from sway bar you all have seen for sale or used on our cars? I think I have seen 38mm but I was wondering if anything larger has been found or used.

Thanks

 

Big is not always better in sway bar size....

 

I understand that, I was just wondering what people have seen and are running

 

I believe the 38 is the biggest.

 

you

Do you sell this size or know where I can get one that size?

 

I was mistaken, after a little research 36mm is the biggest. We only sell a 32 for the 3rd gen but offer a hollow 35 for the 4th gen. Thats where I got mixed up.

Sorry...

 

You don't say whether your looking at front or rear bars, but as said above....Big is not always better.

I have the biggest factory bars on my GTA & I actually want to go SMALLER in the rear.

 

Your right, I should have stated the front. I want a very decent sized from sway bar...38mm if I can find one. My rear I am just going to leave stock. I have heard that a lot of people who go with larger rear sway bars find that the rear tires do not bit as well in the turns and will cause over steer issues. I have actually heard of people running a v-6 rear sway bar and have found improved cornering and reduced over steer issues.

 

IMO, I would differentiate the two types of sway bars first and then compare sizes. The solid sway bars are often viewed as more responsive, but are also much heavier. If you think about it, a solid bar is going to resist torsion better than a hollow one would. I have a solid stock one on my Berlinetta and like it a lot. My biggest issue with these is that the end links seem to like to loosen up.

GM made both styles and are a cheap alternative compared to the aftermarket ones. The largest hollow front bars are typically 34mm and 36mm. I'm not sure about the solid ones though. You could probably pick up a set of stock ones a lot cheaper than aftermarket. Say $50-$100 vs. $300 and up.

Some of the aftermarket ones include BMR, UMI, Hotchkis and Spohn. I've often heard that these bars are far better than any of the stock ones but haven't tried any out yet.

I do have a used set of BMR,s that I have yet to install and the previous owner told me that I would need to run 315's in the back to even things out. They are a matched set so I will give this a try before changing the rear one out. They are solid BTW. I've heard good things about Hotchkiss too, but I'm not sure they're selling the same thing anymore since they only appear to be selling hollow 36mm's.

I think that a set of 17"F/18"R Vette rims and some Eagle F1 GS-D3's would help the over steering issue as well.

 

What have you done to the car so far, and what is the cars factory specs we are dealing with?

Maybe I can give you some different helpful advice other than mounting a massive sway bar onto a car than does not need that kind of roll weight resistance- unless you have installed a big block into it or such?

A sway bar is a fine tuning tool, not a major suspension handling device. You need to have a bar within perimeters of lateral and longitudinal, and height chassis balance.

 

So I am doing TPIS shocks/struts. A prokit until I can afford the Ground Control weight jack set up. I am going to do energy suspesion bushings. I have poly rod combo adjustable Panhard bar and LC arms. I am keeping the stock engine and 5 speed untile things go boom. I currently have 275-40-17 all around Also planning on doing SFC this winter and a 6 point cage next winter....money providing that is.

 

You have nothing out of the ordinary that a big bar 36/23 or 36/19 combo should do great.
