Always stagger to what the chassis needs, dont care what the radius of the turns areSomething just popped in my head . Stagger matching the track radius .
How about stagger matching what the chassis is doing in the turn .
You could be turning from top to bottom not following the turn radius at all .
IMHO, bingoHow about stagger matching what the chassis is doing in the turn .
Including your thought about prepping ...Every once in a while I have seen our normal lap times seem off & our rpm go down some.
Wrong on both takesStagger on the front is irreverent. because the two front tires are not on a fixed axle it wll not force the kart to turn . the chassis manufactures need you to run 'stagger' on the front because the frame is built with different axle heights to accommodate the extreme differences in tire diameter between the left and right. rear stagger should be a compromise between getting around the corner and scrubbing speed down the strait. if you have your stagger matching the radius of the corner you are scrubbing too much speed in the strait.
For his stagger on the front, he is correct. Front stagger does little more than affect cross and ride height.Wrong on both takes
Provided there is no caster or camber involved or steering input .For his stagger on the front, he is correct. Front stagger does little more than affect cross and ride height.

Chassis rake and weight transfer, so no he isn't entirely correct and no they arent welded to the chassis at extreme height differencesFor his stagger on the front, he is correct. Front stagger does little more than affect cross and ride height.

Yes.Provided there is no caster or camber involved or steering input .
One thing that's said ; only affects ride height . Brings the question ? Does ride height affect anything ?
I dont think a sprung chassis would make any difference. The only difference in this case is how the weight is transferred, but either way it transfers. Now with that said, the micro sprint/and I assume full size sprint cars run a very low cross 45-50% and rely on a ton of stagger and dynamic loading to make it do what it does. But with all that said, I feel like the principle still applies the same, stagger only helps because both rear tires are turning the same rpms, while the fronts can spin independent of each other.Provided there is no caster or camber involved or steering input .

I didnt say they were welded differently, but that he was correct with saying that front stagger doesn't make the kart turn.Chassis rake and weight transfer, so no he isn't entirely correct and no they arent welded to the chassis at extreme height differences
Provided you have some sort of differential, and could control which wheel power goes to, yes.What would happen if the rear axle was cut in half. Add 2 more bearings & another brake rotor/caliper setup? Assuming chain drive on right side. Could both rear tires be the same size now? Just curious
Personally, I would love to rent a track for a couple of days AFTER a race day. Left the way that it was, and just kept tacky. I would love to spend days testing, making a small adjustment and running a few laps, learning what it did, etc. The problem with that is the track needs all the time they can get to be ready for the next race, my local track has to have EMS on site for insurance if anyone is on the track, etc etc. Testing is expensive and most of us dont want to risk being wrong on a race night.The vehicles I started racing with were on 1/10 mi. asphalt oval, LR drive only, 2x2 wooden main frame with a full body. We could flex them hard enough to pick that wheel up, and yes, loss of drive. So if you're on an oval and want single wheel drive, make it the outside wheel, for sure.
The ONLY benefits I see to stagger are helping with turn-in and reducing corner scrub. If the track is tacky enough to allow for turn-in without it, it's also tacky enough to unweight the LR enough to run without it. If you can make a kart bicycle, there's enough grip not to need stagger. If it's dry slick, you'd better have some. But don't take our word for it -- go test. Learn. Find a new way. Find a better mousetrap.
It has never made sense to me to over-tire a kart and then remove grip... Give me all the grip I can get and then let me tune and drive to compensate... A bunch of weird work-arounds seem to exist in dirt oval karting that could be solved by more appropriate means, IMO. But by all means, follow the existing status quo from the established leaders. Just keep in mind you'll have to do SOMETHING different to beat the people who are establishing the status quo... Question and reason out everything. I will say that with the amount of weight on a kart, going purely straight, there's no way you can "drive off the left" down the straight, and "drive off the right" in the turns. The "right" is slightly more accurate, but only because of dynamic weight transfer. I'd wager a bit that BOTH tires are in a controlled slip in the turns, and modern LTO karts NEVER go purely straight. So, driving a big ellipse means that they're always living in some part of dynamic weight transfer, and thus you can get away with some amount of stagger. I don't think most people have tested enough to truly optimize every factor.
My feelings exactly!!!It has never made sense to me to over-tire a kart and then remove grip... Give me all the grip I can get and then let me tune and drive to compensate... A bunch of weird work-arounds seem to exist in dirt oval karting that could be solved by more appropriate means, IMO.
