Yes, use scales to get close to this set up then weld,this set up works very well adjust with air pressures at the track.

Great thread! I do have a question... The class I am going to be running in only allows for a stock axle, but, I can either weld the axle straight or use "adjustable wedges" to tune it. Would this baseline setup be something about to start with considering that I can only tune the front end using the factory pivot point? Apologies if this has been covered. I tried a few different searches to come up with an answer doh

Stock axles are for stock mowers... that is why you can't find anything. Very few stock mowers have
an axle that lasts for a mower, much less a racer.

George, I come from a background of full sized cars, I built cars and crew chiefed a dirt late model for a few years. Do you change tire starting pressures when you run tubes. When we ran them the tires would heat up much faster and more due to the friction even using powder in the tire. We would generally set up a few lbs lower. Just for example, We may start at an air pressure of 10LF, 12-14RF 6-10LR and 14-16RR. If we ran a tube (sometimes to help them get heat in the tires) we would start at 2-3lbs less in any tire that had a tube.

No I have run both with or without, mower tires are not as sensitive as a race tire. In fact I never checked the pressures when done with a race to see how much they gained. Now that I only run Super mods with race tires there is no tubes so this is not a factor for us now either.

I understand the limitations of stock equipment. Just trying to make the most of what the rules allow for the class I am going to be running
