Rear Axle / Front End Question for Ice racing

[Krandall]

Figured I'd keep these 2 topics separate since it's 2 different things completely.

When running an oval track, would there be any advantage to keeping the inside shorter than the outside? Granted 1-2" isn't all that much of a difference. But. Wondering if anyone has experience in this area.

i would be more intrested in tire size offset to create wedge, than altering suspension geometry. Atleast while your just learning.

Well I was thinking, would it make sense to put the stock a-arms on in inside corner? And keep the +2 on the outside? the ishock shocks mount right up.

1st off you want as low of CG as you can get, so the stock a-arms are out IMO, if anything a +1 or +2 forward a-arm on the right would be nice.

The sprints run the offset put a 20 on the inside rear and a 22 on the outside they run them offfset like that, why wouldn't that work...

Last season I looked at everyone's quads & don't remember seeing any offsets   At least it wasn't obvious to the naked eye.

+1 forward a-arms will make the rear tires hook harder than stock a-arms.  Mixing arms could become a handling issue. IDK

Low & wide   :grin_nod:

[Krandall]

I don't understand the whole +1 forward thing.. What's the purpose? why not extend the rear? Isn't that the same thing?

[Bert]

I was talking to Dave @ JD Performance & +1 Arms are popular with the sand guys & drags.  For a trail rider a longer swinger would balance the machine again.

[Krandall]

don't the sand guys extend the f*ck outta their swingers?

I don't think the sprints are running a locked rear axle though  That would be my concern on a sport quad

[Bert]

With a extended swinger there's no wheelies but are they hooking up?
Sure add paddles or add forward arms & change the bikes weight distribution 
I've talked to Dave several times & I'm 99% sure I'm clear on what he told me

If you are starting from a dead stop you don't want any type of stagger unless you really want to get to know the guy on your left. Also shorter swingarms work better for circle track, pulls harder out the corner.

The Red 250R is super low


Notice how narrow my buddies (#760) Z400 is with stock axle & a-arms


Cheng Shin C826 20x11x9 rear tires mounted on stock rims, 9 x 8.5.  I would like to try these on a 9x9 rim & flatten out the tire profile, too rounded now. Front tires are 20" Razor MX's.  Z400 has 18" rears & 19" fronts


Z400 would "skate" a little in the tight corners from too many studs



For Cheng Shins try Sully's connection (MAW) or Magic Racing in the Ice Racing section.

Anyone have experience with tire knifes?  I need to know what brand or style to buy

With 2.5#'s of rear tire pressure Dennis's cookie turned into a wheels up situation
 


Sorry for the random whoring
