Addico Rear Sway Bar Size..? Help..

Alright guys, well I found out my rear anti sway bar is cracked pretty badly. I am planning on getting an addco model from Summit Racing as they come as a whole kit , now I have a 3.8 might have some mild add ons. Should i go for the 1 1/4bar or the 1 3/8's bar. The front bar will probably stay stock. I read some old posts and saw things about stress cracking, and lots of oversteer with the bigger bar? Need some help as i put in a hold order at summit for the bigger bar for tomarrow. any input appreciated thanks!

when i put in a 1.25" rear bar it didnt up the oversteer just slightly...not enough to crash or change your driving habits...but enough to put a smile on your fact taking a corner very hard

i left the front stock as well

The 1 3/8" bar is too big when using the stock front bar. The 1 1/4" rear bar is the way to go when retaining the stock front bar.

I'd save tons of money and go with 89 SC bars (1.2'' front and 1.1'' rear). Both of those will make a monster difference over your 1.06'' front and 1.04'' rear.

I got both bars for less than $100 shipped (two different people unfortunately, so shipping killed me). Compared to both addcos which will run you about $300 shipped.

Just check the thickness...you put thicker bars on and it's going to make a noticeable improvement in your handling. I went with the SC bars which saved me a couple hundred bucks (enough for a set of Eibachs) and it does a bang up job. It's not like I take S curves at 70 mph anyway...my tires suck too much and there's too many cops around.

I have the 1 3/8" rear bar with the stock front one. I plan on eventually installing the 1 1/4 front bar, but for now the setup has no problems. most cars push pretty bad stock, ours as good as it is, is no exception. stiffening up the rear of the car will help the car rotate in the center of the corner better. by keeping the front softer you allow the tire to bite into the road better, making the car pivot on the front. It does loosen up the car and make it quite a bit stiffer though.

The 1 3/8" rear bar with a stock front bar will give you a fair amount of oversteer that is why I have recommended that the largest rear bar with a stock front bar is the 1 1/4". I am the person solely responsible for the R&D of these large bars with ADDCO in the first place so I know what I am talking about. If you want the best handing setup and don't mind a little stiffer suspension then go with the F/R 1 3/8" combo. That is the setup I run and would not change it for the world. Using a 1 3/8" rear bar and a 1 1/4" front bar will give you close to the same understeer setup we have in the stock F/R configuration. Matched bars are the only way to go except for the 1 1/4" rear bar and stock front bar which will give good results on its own. MN12s have lots of understeer designed into them. ADDCO MN12 large bars are been available since 1998.

ADDCO for the most part only deals with businesses but as a member of the club you can order directly from ADDCO. The prices on the page listed above are a little out of date but not by a hell of a lot. This club had an exclusive on the large bars for over two years when they first came out so we were the only game in town.

Mark,

What about for launching the car? Will the 1 1/4" rear bar (if I don't plan an changing the front) help with wheel hop? My thinking is that unless both wheels are hopping in synch (not likely) the bigger bar should dampen the effect. Will it hurt launch performance on your opinion (I don't see how it could)? Thanks.

I'd like to go 1.375" all around, but the car is primarily a drag car, and I don't want to sacrifice any launchability.

Either one will help with the launch and wheel hop. Helps keep the rear planted evenly on the ground.

That's what I thought...thanks for confirming it for me. You are the sway bar expert, after all.
