USAC New Rules
 

24 cars start a feature and 5 heat races with a car count over 48. I am sure someone can post the exact rule package.

Two of us were discussing the reduced weight limit to 1350# for National Sprint Cars,subtle way of telling drivers to lose weight? LoL #Asking for a friend.

Re: USAC New Rules
 

I was listening to the competition meeting when they brought up the weight rule. Soooo, you have to add weight to make the minimum. You also spend thousands on titanium bolts and carbon fiber seats and carbon fiber panels. Isn't that the idea of a weight rule? So you don't spend crazy money. Rule of thumb is for every pound you need to lose it will cost you $100. So that means USAC just cost every person that did not have to add weight $2500. There are only a few drivers that have to add weight and of coarse it is their top teams. You know, the ones with enough money to buy titanium and carbon fiber needlessly.

Well friend, step into my shoes and never have to add weight to satisfy USAC!

No worries here!

I’m here to read the people posts with the 1950’s mentality, complain about the format changes. Lol.

The one ignition switch rule is interesting.

What's a Sprint Car built with mid-grade aluminum components and a fiberglass/aluminum body weigh?

I imagine that most existing cars had to add weight so why not prevent having to add weight where a team wants it.

1260, plus driver

Re: USAC New Rules
 

most teams did NOT have to add weight.

Right, so the math doesn't work out for a 1350 minimum unless you have a small driver and a large Ti/carbon fiber budget.

One thing no one on here mentions when they lament guys moving on to wing racing is that USAC consistently screws average and larger sized drivers with their weight rules.

Re: USAC New Rules
 

How's that when most of the tracks have the same rule? In fact more weight helps you on dry slick tracks. pull the wheels in, lower it and add weight.

Re: USAC New Rules
 

Is the under 32 cars three heats rule still in place? I like 4 heats

Don't think you're going to win many USAC races in 2024 running heavy.

Re: USAC New Rules
 

More weight never helps things improve velocity. It also has a worse effect on stopping velocity.

What helps on dry slick tracks is understanding your shock package and purchasing new tires.

From the Press Release:

1312: EVENT PROCEDURE | SPRINTS & MIDGETS

(G) If 48 or more cars are in competition, five (5) heat races will be held with the top-four (4) finishers transferring to the feature.

1. For 28-47 cars in attendance during an event on tracks under a half-mile in length will result in four (4) heat races with the top-five (5) finishers transferring out of each heat.

2. For 27 cars or less in attendance during an event on tracks under a half-mile in length will result in three (3) heat races with the top-six (6) finishers transferring out of each heat.

3. For 31-47 cars in attendance during an event on tracks a half-mile in length will result in four (4) heat races with the top-five (5) finishers transferring out of each heat.

4. For 30 cars or less in attendance during an event on tracks a half-mile in length will result in three (3) heat races with the top-six (6) transferring out of each heat.

So what does a small 3/8ths count as? I mean we get the heat laps of the half miles for some reason.

Re: USAC New Rules
 

Since most are commenting on the weight change, I was hoping you would explain and expand your thought/point about format change? Unless I misread this and you don’t like it. Sorry if that’s the case.

28 cars should result in 4 heats regardless of track size imo. And on half miles they should invert 8 in heats and feature.
