I'm starting to wonder why I bought a new hpi kit when im replacing every part on it with an aftermarket upgrade ....

That's why I go cheap and either get a KM or rovan. Once upgraded the way you want, it's all the same anyhow.

I think the way things are going with all the upgrades & extra cost to keep up were going to see a need for a limited class ... Right now we don't have many rules to keep things in check ( Im talking cost ) So down the road we will see the additional cost lead to less racers ..... Than we will need a limited class ..... This will cause less racers in each class .... So if your track has 12 now ....You might have 8 in limited and 4 in the outlaw class ....

Too many rules is what kills racing. Build it and race. I have done nothing to lighten any of my cars. If fact, adding a lot of the parts I do makes it heavier but much more reliable. I have never DNF'd in a feature.....never. You lighten things up, your looking for trouble of either bending or breaking parts. The track nearest to me, we are lucky to have 4 - 6 cars in Late Model, usually 3 or 4 mods and a couple sprints. Can afford to split any classes.

We have rules that keep racers from doing what ever ...... That's just a base to start from .... Look... i'm not complaining here .... I'm having a conversation about what is good for racing .... We went through all this with 1/8 oval racing .... Limited 1/8 th racing took off in our area when racers saw the cost difference in limited vs outlaw racing .... Last season at our track we had maybe 10 -15 late models average ..... You cant say build it and race it with zero rules .... That would be nuts too .... You'd have people with side damns on their cars ....Its about like the bull dog nose thing to me ...

Different tracks get different numbers of racers. Where you have 20 late models showing up every race, I can agree with motor rules etc. But when you don't have that, you have to just let everyone race. Out West in off road, they have 3 divisions for each class. They are all the same rules, it is just broken down by driver skill level. They also get 30 plus trucks showing up. I 100% agree with different experience levels when you have enough racers to do that.

Do the off road racers/Tracks have a weight limit on 1/5th ?

None that I know of.

I googled it ..... AARCMCC ..... Looks like the Aussies have rules on weight / engine sizes in place .... http://www.aarcmcc.org/docs/AARCMCC%...Jan%202016.pdf
