What is an adjustable wheel base? What does it change in the kart?

Essentially it’s the distance between the centerline of the front and rear wheels. [image] Wheelbase In both road and rail vehicles, the wheelbase is the distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase…

It means the wheelbase is adjustable. :wink: You can move the rear bearings/cassettes into different sets of mounting holes, like when you change rear ride height, but you move them forward or backward instead of up and down.

Here’s a pic [image] You can see there is a series of horizontal holes to adjust wheelbase. In this case the wheelbase is at it’s longest, moving the bolts/carrier to the left most holes would make it the shortest.

I like that they have the vertical adjustment too. I never knew how much wheelbase changed but height was always a huge change. Are those carriers really only held on by two bolts though? I’m used to seeing at least 4

Here’s a stupid thing I just thought of. What about adjusting wheelbase for only one side of the kart? Say a track is exclusively left hand turns except for 2 of them. Would shortening the right side wheelbase but not the left allow for better turn in at left hand turns wit out changing how the kar…

Aaron, An interesting thought. Assuming to do that you would move the right rear axle cassette to its forward position and the left to its rear position. Not sure how that would make the kart handle but that would cause a gear alignment problem. Possible other solutions would be to use tires on th…

[image] Kart republic Information Would shortening the right side wheelbase but not the left allow for better turn in at left hand turns wit out changing how the kart turns right? I must be missing something here. That’s going to make an interesting handling kart. If you think about it… (At l…

Well the first thing would be the axle would be at an angle relative to the direction of the kart, so it wouldn’t drive straight at all, and when you were trying to drive straight, it would scrub like crazy and you’d probably have to have the steering wheel turned 45 degrees. As James said, it woul…

Moving just one side fore and aft in the rear is common in dirt karts. Usually only an 1/8" or less. It does create A little miss alignment in the rear sprocket and so on. Moving your RR forward will tighten A chassis on entry and Back will loosen it on entr. Its not A common GO TO adjustment, just …
