Title: US 2014 Rules
Post by: George Herrin on November 05, 2013, 08:43:35 am
I have to applaud the USLMRA for the direction taken in prepared classes to ensure the safety and well being of the drivers. allowing the seats lower and 40" sure will help in all these roll overs. Will sure help make them more stable. I know not all will like it but if we cant slow em down this is the next best thing. NOW if ALL Sanction body's and clubs will adapt the sport will make some great strides. THANK YOU US for taking the initiative.

The first I heard of these rules changes was at the finals in Ohio this year.  At that point they were proposals, and not in the book.  Now that the 2014 rules are out you can clearly see the steps taken to keep the sport moving forward and in a safe direction.  I will be taking the opportunity to widen my mower to the allowed width.

I agree these rules will make out sport much safer. That is a point nobody can argue with!

Thanks to the National Staff for getting these out early this year. I gave them a quick read and some of my questions have been answered. THANKS!

Love the extra 2" width and the seat rule, should make for safer racing all the way around.

What are the chances of ARMA following suit?

I FOUND NOTHING FOR 2014. ONLY 2013 AND DOWN.

DONT KNOW AS OF NOW, BUT YOU WERE ALLWAYS ABLE TO LOWER YOUR SEAT TO THE TOPS OF YOR TIRES. I GUESS I MISSED SOMETHING!

You can now lower your seat into the fenders but only to a minimum of 13" from ground to bottom of seat.

Lester you asked if ARMA was going to follow this?

ARMA already allows you to be 13 inches off the ground by letting you run 6" wheels on back. seat can be no lower then top of tires. this took care of a lot of tip over problems already. Plus you wont have to hack the crap out of your fenders to do it. Being this low already takes away a lot of the need for extra width. But I would say that I like the idea somewhat of couple inches wider. :twocents:

Can you add the 2" to the right side to make the 40" width?

In discussing this with a fellow racer an intresting law of stering came up. This racer is running a couple of my axles and was telling me he could simply take the spacers off the outer part of the spindle and move his tire out a inch on each side and put the spacers on the inside. Although this is physically possible, it would totally mess up the scrub steer I designed into the axle. The only way to keep the  (what I beleive) is the proper scrub is to cut the axle and move each side out indepently of each other. Just spacing the tire futher out on the spindle away from the king ping is making the angle much worse.

I bring this up in the intrest of safety, as tech inspector I saw a lot of machines come through with scrub angles that were excessive, how some of them got arount the track was amazing and a lot of the times they were not the front runners.

I also see excessive scrub angles on front axles that incorporate front disk brakes. You have no other choice other than run a disk which would fit inside the front wheel and allow room for the caliper. We see it also in our Pro-Mod (NNYLMR) class where chassis were built to the SuperMod ARMA yet they decided to "widen" out to our 44" limit (we do all we can to keep racers legal that were built to our rules before our adaption of ARMA). The only proper way to widen the front stance is to use a wider beam. That is why I'm asking if ARMA is considering to change it's width.

Very well said  I already have had a few inquiries for my spindles and wondering if I could make them longer. and this is what I explained to them.

Thanks Tommy for putting it on here.

Btmra will be allowing these Chavez beginning with the 2014 season. I think it's great!!!

Dont widen the scrub, just run wider wheels.

No Tom you cannot no offset in Prepared classes


We are seeing what doesn't work.

Lets try something that does.

It is painfully obvious the 8" rear wheels aren't the way anymore in the higher HP machines (CP/BP).

Just going to a 6" rear wheel would solve a lot of the problem. Look at ModX and Super Sportsman.

Just because the rule has been no offset why can't it be changed???

Why not allow a 2" offset on the CP/BP and for that matter ModX/Super sportsman.

Change overall width to 40"

It wouldn't take a major rebuild to get the either.

The other classes could stay as they are now.

8" wheels are not the problem.  I think most would agree Chuck Miller, Rocket Ron's whole crew, and a few others have made them work extremely well.  Look at the prepared class results from the All American (BP), results don't lie.  8 inch wheels use bigger tires, bigger tires equal more traction, how do tell is that not working in the high horsepower classes? Offset is not the answer to me because it looks awful as a prepared machine, remember everyone does not want an offset go kart chassis with lawn mower sheet metal.  These changes are far enough reaching that I think many can make the changes and be safer/faster with very little being spent to do so.

Post by: George Herrin on November 06, 2013, 03:30:47 pm
8 inch wheels are not the way.... I disagree I ran both on bp/super sportsman and  the 8 were way easier to hook up. The rules for us are done trying to reword or change at this point is pointless. Try to get Arma to change also so that those that Wang to run 8s won't :censored: at a center of gravity disadvantage even the playing field. Plus you won't alienate the us racers from running arma.

Post by: fx28 on November 06, 2013, 03:50:52 pm
The seat height rule at 13 is probably the thing that will have the most effect on rollover. And finally we have a benchmark to build off of to make all chassis equal. George I ran the 40" at the all American and really did not see any difference and I obviously was not the fastest guy in the class.   What we will have now is faster corner speeds and hopefully will not magnify the problems we currently have.  Thinking the 8" wheels are painful to run........., well just keep thinkin! lol!!!!

Do you mean better than is what is in the rulebook?  you can now pretty much modify to what it takes to get bottom of seat to 13" . What the rule book pictures suggest is how they should  look when you are done, smooth and pretty not hacked and mangled.

Yes the pictures in the rule book. Those pictures are not very clear to see how it was smooth and sharp edge free. Are there any other pictures that show this better?

Tom L. came up with the best (so far) idea on how to extendthe tires out 1". Fab a 1" spacer to go between your axle and your spindle mount.It's a little tricky to drill the holes on an angle, but doable if you take your time, assemble it with some grade 8 bolts, fab new tie rods and you should be good,

thanks Tom!

Title: Re: US 2014 Rules
Post by: fx28 on November 07, 2013, 01:33:58 pm
A couple ways to widen, 1. 1" wider rim    2.like Tom says put spacers in at heim. quick and easy way would be all thread connecters. heim would thread in on one side and grade 8 bolt on the inside.  3. remove front axle and cut in center and add 2" spacer and then lengthen tie rods.   Any of these are not really that hard or to expensive to do, but like I said before I have ran it already and really did not see much difference.

George I will belive it when I see it !!!!  lol !!!
