As some of you my have read in the past, I am think about building a 95 xcr sp chassis into a sportsman 600 sled. My question is, do I want to offset my front suspension to the right, by narrowing the left and widening the right side. if so what are some good dementions and what about setting the camber and the sway bar( this sled did come with the aluminum adjustable swabar)? there are also a few things i'm in need of;
oval ski's and carbides (stock poo spindals)
oval bars
race leagal belt gaurd for an Indy chassis
some good clutching and gearing idea's for a 44O with a team or a button clutch, I have both to choose from. which is better for ice? thanks guys.

Offset to the right does help, maybe one of the other sportsman guys can share what they have done. We offset our F500 1 inch which is the max allowable for that class. I don't think there is any limitations on that for sportsman 600.
We also run quite of bit of negative camber but that is something you just need to test and find what works best with your setup
gearing changes from track to track, I would start with gearing for around 80-85 mph
You will definately need a stiff swaybay. I don't know if those stock aluminum ones are stiff enough
Timmer, can you answer some questions, I know that is about the same vintage of chassis that you run.

Not sure if "they"(depending on which circuit you want to run ) will let you "offset the frontend" on that sled .It has to be stock.I think i posed the ?? to JK from USSA about 4 years ago and he said to keep the stock radius rods.Might want to reinforce the lower right side bar with a piece of angle iron ,etc.It will have a tendency to bend !! That was why i wanted to go with custom made ones .....!!! No offset, no custom radius rods i/e "exotic frontends" i believe was the term used.I would find out from whatever racing organization you plan to run ,about using solid frontend bushings or if you have to run the stock ones.In either case.Replace the old ones for sure.It will tighten up the frontend as much as you can.
I would put some neg camber in the right, but make sure to check bump steer !!!
sway bar The racing book put out by Polaris in 95 said to keep the swaybar neutral for oval racing .Meaning no preload .I imagine you can get arguments both pro and con whether to add a little preload or not .Depends on how you have the rest of the sled set up and how you like to drive it.
stock clutch cover should be fine.
clutching....Testing ,testing ,testing.. My man !
Geez dude ! ..... i should just sell you mine !!lol Its all ready to go just sitt'n in the shed the last 3 years

thanks guys, Mike back to what you were saying aboiut the sway bar. As i recall. back in 95/96, when we raced MRP, we were told to swich out the (stock)aluminum(sleeve with a steel bar in side)swaybar with a regular one piece torsion bar like most standard sleds have. I think the reasoning was it was to stiff but that was for le-mans racing. I'll have to give timmer a call and get some of these other issuse figured out. Getting excited. been slowlly getting some of the smoll things out of the way so once I get the motor mounted I can really dig into it, Just hope I have it ready for forest lake.

Bobby, if you need anything else or any other help, let me know. Do you have an oval racing track for it? That is extrememly important

Mike, I might be looking for some 8" front fox shock for the front. I think the stock 10" shock body's might be a littl to long. I have the origional track for that sled wich is it think 5/8" poo track from 95 with the Hooker setup on it from when we raced MRP. If I remember rightfrom Haydays, Timmer has the same track on his sled. He had the Hooker set up but wasn't in use.

I can fix you up with the right shocks, the ones you have will work just fine I just need to shorten them

I realize they need to be shortend mike, that is not the problem though. with the X-10 shocks the will loose travel because the body is to long. and if I remember right when we use to have them shortened there wasn't but an inch if shock travel left. so a non x-10 shock would work better i believe. I'll know more in a week or so when I start to put the sled to geather.
