yea we dont run them either take um off
it will only hurt the performance of your suspesion..
its kind of a common thing..
when you go in a corner the sway bar is lifting on the lf tire ...
so when you take off the sway bar it's like having an independant suspension..
allowing the tire to stay on the track allowing suspension to work correctly...

Well iam going to have to disagree here on this one and heres my argument
The sway bar help keep your front end stable OK now then take that away and all you have is spring and shock control to help stablize your front end people will say that w/o a sway bar your front end has more flex well yes true. BUT you really dont want your front end to flop around or bounce around now granted on a ruff track they can hurt you BUT on a smooth dry track they are a big advantage to you thats why eveyone that is fast on ASPHALT runs them cause the track is smooth same way on dirt it helps STABLIZE your front end
Hopefullly i didnt confuse anybody on that

I have to go along with the swaybar on a dry slick track also.The track I run is a low banked D shaped 1/2 mile and is usually pretty smooth and always dry and slick.I run a monster 1-1/4 inch bar with a soft spring setup in a metric chassis.Almost all the frontrunners run a sway bar the few guys that dont run one are fast in warmups and heats but when it dries up so do their lap times.I have always wanted to expiriment with a bar but with 6 wins and all top 3 finishes the second half of last season I have to lean with keeping the sway bar.

If its alway ruff and tacky then i wouldnt unless you can find a small 1 inch bar off a v6 monte
The main reason that mods dont run sway bars it that there car is totally different then hobby or strret stock s( of course evyone knows that) but what iam getting at it that they have a lot more tunning that you can do to help them turn and go trought the corner plus most of the time they are always pulling the left front wheel and unless your really running some soft springs and want to be at the back of the pack on three wheels i would never run my hobby on three wheels

the sway bar?

The springs?

with or with out....

i took my sway bar off and needed a stiffer right front spring. too poor to buy another so i bolted it back on for now and it seems to work ok.

Bad thing about it, is the extra front end weight...not needed!

We use no bar with a 900-rf and a 700 lf it works really good for us.It goes agianst everything i have read or learned,but i can't argue with the results.Red and white car on the low side in pic.

Here is something to think about when to run one or not run one?

Excessive body roll loads the outside tires which creates understeer,sloppy handling and MOST of all a dangerous situation in sudden maneuvers.
A sway~bar gives your car better balance in the corners by reducing body roll and the understeer conditions associated with it.

A sway~bar provides less unloading and loading of the chassis and suspension then without one.

I agree with iowa, although I can't run a sway bar cause the track is way too rough most of the time. I race at a wide high banked 4/10ths and excess body roll on a dry slick is NOT good. So the only fix for me is stiffer front springs (1300 rf and 1000 lf). It would be nice to soften the front up (springs) so I can get more "control". Oh, well.

On our Late model when the track gets dry/slick we try to get the car to roll over to plant more weight on the right side tires. A sway bar by design tries to lift the inside wheel when going around the corner and the body is trying to roll. On asphalt 99.9% of the cars on the track have them on. Think of it this way Asphault is smooth and has a huge amount of traction through the corners, They use a sway bar. If sway bars were good on dirt don't you think every late model or Northern modified would have one on it? I was in the pits lastnight at the Late model nationals and there wasent a swaybar on a single car.

Man, I don't want to get blood pressures high on this, but my way of thinking on tacky vs. slick on dirt is this: tacky, get that right rear (and front) to DIG INTO the track, and pull you through the corners. On a dry slick (where you CANNOT DIG into the track surface) you need to get ALL tires gripping as much as possible, because the track surface will not allow you to hook up with anything less. I preach setting up a car on a dry slick to lessen body roll, watch your tire pressures closely, and get more tread surface consistently on the track surface in the corners as you possibly can. You just can't get a right rear or right front to dig into a hard, slick track like you can on a wet/tacky. So it makes scense to set the car up to have all four tires doing equal duties with getting traction in relation to the track surface. It has worked for me and I have witnessed the opposite for other race buddies who have tried even harder to get the right rear especially, to dig in more when the track goes dry slick. This is JUST my opinion, but I say again, a TRIED and TRUED set up, at least for me. I love this forum, and I hope someone might see the sanity (or insanity) in what I am posting here! Either way people, RACE ON!!!
