I am having the hardest time trying to find any SKM 50mm axles that are 1020...

On my current track my fastest times are ran with the 1020, hubs all the way inboard...

This being said, I do not want a 1040 etc.

So, Can anyone help me find an SKM T2 (medium) 50mm 1020 axle?

You can get them from IM:

Or, if you're in the Chicago area, you can get them through L.A.D. Specialties. http://www.ladspec.com

Remember, axle width and where your rear track width is at have more to do with where YOUR center of gravity is (both vertically and fore to aft), and can vary greatly from where your competitor is doing. A 1020 axle with the hubs all the way in is a rather narrow rear track. Though I don't know your track, it's conditions and what tires are mandated, I would think that this set up would work for few drivers who are near or at adult proportions.

Yeah, Im a pretty small guy

Driver weighs 135 at 5'6"

Intrepid cruiser 30mm chassis with Rotax 125, racing SR Rotax/Sr Tag. Weighted to 365.

I have practiced at Phoenix once, but do most of my driving at Musselman in Tucson Arizona.

Because of the excess amount of weight needed I am not able to go up the back of the seat, so the kart has a relatively low CG.

With a 1020, I am able to get to 1040 axle length just with hub adjustment, however I am scared if I go 1040 I will be screwed when I want to go narrower.

Quite frankly I have only played with rear axle width a slight bit, but when I did mess with it, I was faster at 1020

I found IM right after I posted the question! but thanks!

Now any insight on why I would go 1040 instead? Just curious f maybe I didnt go wide enough, and was in a limbo that wasn't as good as my narrow set up

At that weight, the narrow set up is likely the way to go. The ballast that you have, since you're on the lighter side, is probably on the seat. If my guess is correct, it's probably pretty low on the seat as well. If that's the case, your center of gravity is pretty low, and you could use a narrow rear track so that you're transferring weight to your outside rear tire with the greatest efficacy.

If you go the opposite way, and try a very wide rear track, my guess that you would wind up either flat sliding the rear, or have oodles of understeer. Either way, it's not the fast way to get around a track.
