Default Strano rear sway bar vs stock

Already have the Strano 35mm hollow bar on the front and very happy with it. I still have the stock 19mm solid bar in the rear. For Drag racing, how would it benefit me to buy a 22mm Strano rear bar and ditch the stocker?

From a drag racing perspective, it would help keep the rear of the car more level launching out of the hole. That seems to be the general trend with the rear sway bars on drag cars...bigger and heavier to keep the body from twisting from the torque being applied in such a short amount of time.

This would be an extreme example (I think he had a sway bar link that broke):

If the car winds up a bit on launch (and you need a little traction for this to happen), a larger rear bar will keep it more level and lessen or stop a pull to the right. My rear bar is also a few pounds lighter than the stock rear is (about 5 or so), which isn't much but it's something. It's also unsprung weight, but that doesn't matter for drag racing... Simply makes the weight has to move up and down over bumps a bit less which makes the wheels tend to follow the road a little better.

The biggest thing isn't for drag racing. It simply will bring the car's balance more back to where it should be. The 35mm front is meant to be used with the 22mm rear as a set. The only time I use the front alone is on F-stock autox cars because we can't change the rear under the rules, and the front still helps the car go faster.

A 35mm front is about 45% stiffer than a stock 30mm on a Z28/Formula/TA. It's about 30% stiffer than a 32mm from a WS6/SS/1LE. The stock rear bar is 0% stiffer. The 22mm rear is 33% stiffer than stock. You can see that a pair of our bars keeps a very, very similar ratio F vs. R to the 32/19 combo that SS's and the like come with which is what I want, just with more roll control overall.

Is the bar size any different other than the diameter of the tube? I have a 12 bolt and it rubs on the housing already. I am afraid that if I got something with a larger diameter then it would just rub even more on my rear end housing.

It's meant to fit directly in place of a stock GM rear bar. If the GM bar fits, mine will.

I just randomly pulled a rear bar and compared it to a 23mm bar from a 3rd gen, and the center of the bar would actually be a touch further away from the pumpkin than that particular GM bar.

Understand that with the rear-end not being anything that was available from GM, and that the bar wasn't designed around a 12-bolt, but a 10-bolt that I can't promise you the world here on fit. You might have a huge diff cover that just sticks way out. But it seems to me that you'd have more room with mine than less.

If it's tied to the axle tubes with u-bolt clamps, you can adjust them by loosening and rotating the clamps on the axle tube. That should get the sway bar off the pumkin/ rear end cover. I'm guessing that's where its rubbing.

I could but it has the little damn clips that hold it in place on the Strange rearend. Also, if I rotate it that way to get it out further, how would it hook up to the linkage bolts that tie it in to the undercarraige?

Wouldn't the ends need to be physically longer to accomodate a little more space?

Hey Sam, just curious, would you be able to use the rear bar off of a third gen for the f-stock auto x, or is it more strict than that? IIRC you can get them from 21-24 mm.

The rules are quite strict, can't play rear bar games in FS.

Now you have me thinking Sam. I have your 35mm solid (circa 02') with a 21mm 1LE rear. Would I be better off with your 22mm hollow rear bar?

Better off? Well, it's about the same stiffness, but around 6 pounds lighter which is never a bad thing. I'd love to see you change, and it would save some weight (and I know your car has a lot stripped out for that reason), and it's unsprung weight too. But I can't say you'd notice a huge difference.

Now, do the rear bar and the front bar and you're looking at saving about 20 pounds.

Now that I know how much lighter your bar is, I may be getting one for my car instead of going with a GM bar. I have a 19, 24, and (Spohn) 25 and am looking for something between the 19 and 24..
Are there any 3rd gen front bars available that are lighter and about the same stiffness as the 36mm hollow?

^^Might want to hold off on the front sway bar until after you swap in a LS1. The 36 isn't heavy and will probably be too stiff for the lightweight aluminum heads and block LS1's

If you're looking for a way to eliminate twist on launch, check out our anti-roll bars available for the 3rd and 4th gen cars. Bolts in place of the stock panhard bar and brace and eliminates the need for an anti-sway bar. 5 lbs. lighter than the stock parts removed and completely eliminates any body roll on launch. It's a new piece and not on our website yet, but there are pics of it floating around this site and in the new products section.

I've had the 36mm on my car for a year now... too late to hold off.

Once it's hollow, it's about as light as it's going to get.....

We also have 25mm hollow rears as well. Not what I run for the best handling balance in most cases, but if you need more than a 22mm hollow will give, we can still save you the weight with more rear roll stiffness. Just an FYI.

Alright, Thanks.
I'll be sure to get the 22mm when I get the money and get my springs and SFCs out of the way.

$405 would cover it. I'm out of fronts for the next two weeks or so, but they have already been cut and are being bent today. Powdercoated hopefully by the end of the week, and on a truck to me probably right after X-mas.
