1 1/8" or 1 1/4"

Okay, it's time to get a ADDCO rear swaybar. SInce i already have sport suspension (JJJJ code on door jams and on springs when i installed my EIbach lowering springs) should i hop to a 1 1/4" rear bar and keep the factory sport front bar? Or would that not be a wise choice as far as balance? The car is lowered on Eibach springs and KYB shocks with 245/45/18 tires. Thansk alot for any help.

Only one of the Sway bars in a Sport is larger than the regular bar. Can't for the life of me remember which one it is now. I'm pretty sure its the rear bar that is larger. Anyway, I've been told that it isn't a good idea to get too large a rear bar, without an increase in the front bar. (I think its something like the front should be larger or the same size as the rear). With that said, look up the stock sizes for your car and get the bar that is closest in size to your front bar.

Edit: I just looked them up. You've got a 1.06" front bar, so I wouldn't go any larger than a 1 1/8" rear bar (1.125").

Of course if you can get a set of 89 SC bars you'll save money and be able to get a larger rear bar. The 89 SC's had a 1.20" front bar and a 1.10" rear bar.

In case you're curious as to the "why" about all this. with the larger rear bar you can get excessive oversteer (I think). Though most cars are manufactured with a little understeer built in as they feel its safer for the average driver.

The oversteer problem is true. I heard installing the front bar is teh suck, so that's why i kinda turned away from installing a ADDCO front bar or as you said SC bars. Another thing that i was thinking about is on my next set of tires i was thinking about going to a staggered set up (bigger rear tires) with that said wouldn't getting a larger bar to compensate for the tires be a good idea? Also do you think i'd see much a difference by jumping up to a 1 1/8" bar? Thnanks

I found that the hardest part of the front bar installation is cutting this out:

This bracket was used when the car was on the assembly line and no longer has a use. This bracket must be cut so it is flush with the bottom of the inner fender so there will be room to remove the sway bar. You can use a cut off saw of some type or a hand held power grinder or a cutting torch. A hand held grinder makes this a very simple task.

Once that is done the rest, though very time consuming, isn't that bad. Just follow the instructions here carefully:

http://www.tccoa.com/articles/suspen...ll/index.shtml

And its really pretty simple. Just be sure to set aside an entire afternoon to do it.

I installed the 89 SC bars and noted quite a difference in body roll, though I'd like to increase oversteer just a tad and install the 1.125 bar in the rear. (If I could afford it)

If you are going to stay with the stock front bar then go with the 1 1/4" rear bar period. If you are going to change the F/R stock bars then go with a matched set of ADDCO large bars. This question keeps coming up all the time. The 1 1/8" rear bar while a good bar does not hold a candle to the 1 1 /4" bar for handing when used with a stock front bar. Please trust me on the above info

Oh okay cool. I just wasn't sure if i should go up to a 1 1/4" bar and make the car "unsafe" and unbalanced. I was pretty sure by researching on this board that by going with a 1 3/8" bar in the rear and keeping the stock in front i'd get oversteer. But it was unclear about doing that with a 1 1/4" bar. Thanks alot for the help everyone. I think i'll go ahead and purchase the 1 1/4" bar.
