Overall, I am very happy with the way it is working. It climbs awesome, and the suspension is working great.

Problem list:
It's too tall
Therefore it tips over too easy. <IMG SRC="smilies/biggrin.gif" border="0">
In the past 10 days, we rolled it 6 times. <IMG SRC="smilies/eek.gif" border="0"> The two times it rolled with Bob and I, I don't feel that it should have. So what to do?

Well first and foremost, Jason and Trevor built the rig for bigger tires (42+). I've pretty much decided on the 37" MTR as the tire I want to run. They work great. So I need to lower my rig. I don't want to loose too much belly clearance, so I will lower the suspension only a couple of inches. I think we will lower the hood a few inches for better visibility. We are tossing around putting in some air bags on the rear springs, and some sway away shocks @ 175psi front and rear. Some bump stops front and rear (possibly the trick air stops) and I think she will be a serious sidehilling mo-fo. Any suggestions?

what is that sayin? Wider IS better?? what axles are you running? ever thought of some 2.5 ton rockwells? detroit avalible, low gears, can be made with more clearance than a dana 60, WIDER, almost unbreakable (we need a camo test for that one) and arnt much more than 60s. just one idea.

maybe add a few inches to your wheel base and lower it a couple - at the same time maybe take your- t case and eng- up an 1" or so for better clearence on the bottom side- might want to do a 2 piece front line to get more there too- has the front line ever dragged? maybe even think of going to a larger heavier t-case for center of gravity - Jess -let me know if your in the mood for the d-300 brake - long tail?

no wheel stands are not a problem. I fixed that problem. The vehicle climbs AWESOME. It simply turtles on it's side too easy. <IMG SRC="smilies/wink.gif" border="0">

Wider is not better in a competition rig. You'll run over every flag on the course. <IMG SRC="smilies/wink.gif" border="0">

With the MTR's my rig is 79" wide from outside to outside. That's just about where I want it.

oh thats right its an arca rig. humm how about keep your current suspention and use a hydraulic cylinder on each wheel to help you stay level. you can get them so that while you are not touching the lever they will float but you can also get rid of yor shocks and use flow controls instead. you would be surprised of the possibilitys with hydraulics.

i have always wonderd about hydrolicly controlled shocks ? a proportioning valve or something similar - or even a totally hydrolic shock set up that is controlable up and down ? would that even be legal in arca? or workable - would you have to have 5 hands to still drive and adjust? it could be done-

Forced articulation is illegal in ARCA. <IMG SRC="smilies/wink.gif" border="0">

is the belly a flat bottom? if not you could always keep the motor/trans/t-case the same altitude by tucking it up as you lower the suspension, get all the weight of the cage and passengers lower. maybe some kind of home brew "antirock" for sidehills. <IMG SRC="smilies/usa.gif" border="0">

Maybe your problem is operator error?! <IMG SRC="smilies/thefinger.gif" border="0">

I dig your cruise. Run as little lift as you can to fit the biggest meats you can. Beyond that, driver makes up for any differences.

Put a Cruiser hood back on it when you cut that down.

If you stay leafs in the front, put some like Gearman has, that will lower you.

I noticed the coil over guys had a better time when they hammered their rigs on bumpy hills. They seemed to stay stable and not bounce.

The worst were the TJ based rigs, they bounced like hell under power and rolled a lot. (great pics)

The most stable rig I saw there was Chris Durham's. Rock solid, but too wide for you it sounds like.

Have you thought about training wheels <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/wink.gif" border="0">

I can testify to that! We hit ass loads of flags in Cedar City. The rig was super stable off camber, but we had a hell of a time getting it through the gates. The two things we need to work on are our width, and our turning radius.

Definitely narrow or at least change the
hood on the rig.

I knew the first time I saw the front-hood
framework going up that you never be able to
see anywhere near the right front tire.

Throw a couple of gallons of water in each tire. Is that illegal? <IMG SRC="smilies/biggrin.gif" border="0"> My dad does that in his tractor tires for just that reason. It's much more stable off camber and it get's better traction too.

Probably kinda hic-rigg'n for ya, but what the hell, I threw it out there. <IMG SRC="smilies/biggrin.gif" border="0">

Well, that means you can't run airbags then??? What about the scorpion, that AES is forced articulation???

I would put a D60 up front, that would put more weight down low. I would also put some kinda of anti-rock swaybar in back, in the pics it looks as if to much rear flex is part of the problem.

the water in the tires thing really helps for traction---at least in 2wd tractors. With the tires full, the old tractor would flip over backwards if you tried to tow something real heavy and weren't careful! It also has 5' tall nobbys. I say give it a try, and don't tell too many people your secret! <IMG SRC="smilies/usa.gif" border="0">

Lance, can you give us some close up pic of your suspension? Maybe a few of the underside and also some of the areas you feel need improving. I've never seen your rig up close but i've hear mention of it. Would like to see if it is not a design flaw. Don't want to push any buttons on that comment but ya never know. Congrats on ARCA.
