What is the difference between an imca nothern sport mod and a modfied,
I know the engines are different as in fuel, crate, claim, between the two classes, what else is there,
For example I went to a modified race and there was all the cars running, mods, crates, and claims,
So can some one explain this to me, Thank you,

Mainly the motor and rear suspension. The Mods have four links, spring sliders, springs and shocks mounted differently, and different pull bars. The northern Sport Mods have three links with the springs mounted on top of the reareend and a solid pull bar.

Thanks for the answer, So a northern sport mod can race against the mods, and the mods can't race in the northern sport mods, Correct or Wrong, Thanks

Yes. Just need to check the rules, for sportmods, on rear spring and shock locations.

So are all modifieds are welded up to be a modified or a sport mod, and then you can make what you want? one or the other, I ask all these ? because when I look at them, they almost look pretty much the same, I see where the rearend is diff like in the springs over the rear axle,
Do the frames have the mounts to make the car one way or another?
Thanks Confused for helping the truly confused out, Thanks again

The Sport Mod class was started using older Mod chassis. They have evolved some. Most chassis builders build the car for the class. If you have a mod chassis and you want to move down, some changes will need to be made. They are simple though. Most that I have seen use the same four link brackets for a three link set-up. Just don't use the top holes. Thie big difference is the shock and spring mounting locations and angles.

So based on your last statement, I'm in Wis, Imca land, I was looking to play with a modified, not a sportmod,
So with that being said, what kind of chassis is built for this class, I assume Harris is one of them,
And with a used mod, what year are you talking as for as evolution, like 2008 and newer or what years?
Thanks Confused for the info that you have provided me, it helps alot

Currently the big things with the A mod class that I see are everybody is running a chevelle stub with a 4 bar setup. This is very complicated setup and something I would not recommend "playing with" unless you have some pretty extensive 4 bar knowledge.

So clbaker25x, With what you have said, I should start in a sportmod, and learn about a 3 link rear suspension and then move to a 4 bar/link rearend,
I have a 360 sprint motor, I would like to run the hell out of it, I messed around with sprint cars, although mods seem a whole lot different,
So I guess I could get a sportmod and put a alky motor in it, and run with the mods,

That 3 link sport mod is never going to run with the A Mods. To much advantage with the 4 bar setup. I wouldnt be afraid of the 4 Bar car. If A mod is where you want to be, the sooner you get in there and get your feet wet the better.

ddsprint, I just think you need to temper your expectations and work with a reputable builder that is running well in your area. The 4/4 floated is a pretty different setup to drive and work on. There are a ton of different changes that you can make that have a very specialized and have side affects that you need to know.
96m is definetly right that for most drivers and teams they are not going to be able to keep up with a 4/4 with a 2 link unless they really know what they are doing. We are planning to go A mod next year with a 2 link, but we are doing some things that are pretty agressive with our Sportmod now and will be changing the setup quite a bit when we go to A mod to keep up (adding a brake floater, going to spring in front on left rear and different things that will allow us to have some of the advantages that are built into the A mod class).
With my personal experience we had run previously with another driver at Beatrice Speedway and were a top 10 car and an occassional top 4 with a 2 link. We also finished 11th at the Nebraska state fair race against 77 A mods as a 2 link (we were the only 2 link that made the show). We switched over to 4/4 and we were never able to get it to work right and it ended up basically breaking our race team up due to the frustration of not being able to get the 4/4 figured out. We didn't have much support and were basically trying to figure it out on our own. I had done a year previous working with Matt Richards racing 4/4 at Junction Motor Speedway and I-80 so I had some knowledge on the setup piece and what changes made what happen. The driver was never able to get the car figured out.
If you are going to go 4/4 get some help on both the driver and suspension side to help you learn the setup and how to make the car work. That is probably the single biggest thing with the 4/4 deal is having help that can make it work.

I am in the same situation, my car has 4 link and z bar mounting brackets, but the person I bought it from set it up to run with northern sport mods. My local track only runs a-mods, I dont have any illusions of running them all down, but I can pass some of them already with only a couple races under my belt and not having it set up very well. My thinking was just leaving it 3 link to get some seat time in the car and get a feel for what it is doing and what it wants if that makes any sense. I figure once I am able to tell what the car needs, it should be easier to make the switch to 4 link, although they are very different. One other difference with the sport mods is they get to run a spoiler, you will have to take that off to run with a-mod class.

One very important item to remember, driving a four-bar car is different than driving a 2/3 link. You need to be much smoth with your hands AND feet. The only way to improve is seat time. If you have someone with experience to help you, the learning curve will be much shorter.
Some drivers don't use a 90/10 and some do. It affects the manner the car enters the turns. I don't use one. If I get completely out of the throttle, the car is very loose on entry. I need to stay in the throttle some while braking. This style also helps to keep the suspension loaded.
