I was just trying to settle a debate about 4 bar seeming to have the majority on winning races. But I do believe there are some awful good 3 links out there still making 4 bars look bad. I was just looking for some opinions to see who's right. My point being that 3 links aren't a thing of the past or for beginners, but can still get it done. Thanks

depends on the track. On some tracks that are pretty tacky and/or rough I think the 3 link can be good. It gives you a bigger sweet spot on setup. You can be off a little and still be fast, but on a dry track a good 4 bar setup will hands down hook up better. If you get someone who really knows the 4 bar and stays on top of the setup I feel they will be faster everywhere.

At our weekly track, even 3 years ago there were only a handful of 4 link cars now prob half of the field is 4 link. I think there was maybe 5 races won last year by a 2 link and only one of those was a long 2 link, rest were short bar cars.

Thanks, appreciate the reply. Might have to admit I was mistaken.

Up until this season we have always been running a floated version of 3 link and have always managed to win a few races, while racing on mostly dry slick tracks.....but this year got ourselves a new 4 bar\Z-link car ...and have already won 2 races in 4 trys out with it. I think I'm sold! (were leading and running 2nd when mechanical breakdowns occured in the other 2)

We just won our heat & feature this weekend in a 3 link car. We have 3rd a 15th (broke) a 2nd and a 6th. so far this year. We've been working hard on our set-up. and we're running with the best of them.

4-bar cars are great, and there fast but they have a big downside. There easy to dial yourself right out of the game.

You constantly have to adjust them, your always playing the game of to much this and not enough of that, track dries out, and your playing the game in the other direction.

As well i think there very sensitive to speed, and the line you drive on the track.

There not for a lazy pit man / crew chief, you got to make changes and know what to change. Rarely did i ever go to a track and not change anything.

We switched to a 4-z this year to help smooth this issue out hopefully, but i do love how a 4 bar cars enters the corner, non faster.

At one local track a leaf car (homebuilt even) has dominated everyone for 2 years now, the track is always slick and smooth. Its a thing of beauty really, the car is flat and straight all the way around the track. The rest of the top 10 is usually pretty even mix of 3-link and 4-z cars out of a field of 30-40 total weekly. It seems to me that with the 4-z cars the car is driving the driver more than the driver is driving the car. Reguardless a good driver is going to run good reguardless of what suspension they run.

I agree with kromulous. The 4 link has so many more adjustments that it is easy to dial yourself out. BUT that can be done with any suspension. I think one mistake many people make is thinking they have to be constantly changing stuff, even as the night goes on. Fact is for the most part once you get everything set you wont mess with 4 link stuff that much.

'I heard an interview with Jason Hughes once and they asked him what he thought the biggest difference was bewteen loaca weekly races and touring USMTS guys. He said he notices that the local guys change stuff all the time. He said most of the USMTS guys for the most part go to every track with virtually the same stup and maybe change 1 or 2 things and that it'

I think that holds true for any car at any track.

I agree with Dirtbuster. It seems like every suspension setup can be bad fast with a driver who does their homework. I've also seen the most basic 3-link just kill a whole field of 4/4 and 4/z cars.

I currently run a 4/z combo car. We've gotten the car very consistent now on a variety of track conditions, and we really don't adjust the bars that much anymore. I change tires, panhard bar, and bite mostly. We also change shocks and springs, but nothing radical. We moved the RR spring on top of the housing, LR floated behind, long pullbar, more LR bite, and a better shock package, and now the car is much better.

Still, the biggest change I can make with the car, is in the way I drive it. It seems like I can change the whole attitude of the car with the way I enter the corner; either letting it roll smoothly in, or attacking the corner.

When you watch the USMTS guys race, their cars are pretty consistent, and driveable. If you are driving the car, and not getting controlled by the car, you can change your line and pass cars. The biggest problem I see with a 4/4 or 4/z car is getting them too tight and too stuck. A little more free/loose setup allows you to be maneuverable, and quicker. A 3-link is more forgiving, but a driveble 4-bar is wicked fast.
