.087 axle vs .092 axle

Post by Speedster » Sat Apr 06, 2019 4:59 am

Newbie here on this topic.
Drifting a Class "B" truck with 4.75 ounces of weight on the dfw of a 20 ounce truck. The drift is 1/2" in 5'. 3 wheel rail rider. Axle bent at 1 1/2 degrees Positive camber. Stock BSA wheel.
Does dfw axle create the same amount of friction against the rail and the wheel or does one create more friction and make it more difficult to tune ?

Thank you.

Well Speedster,
This is a good one!

Small vs large axles! And drift with stock wheels

My thoughts are the smaller axle size would have more
Movement or slop in the wheel bore because of the
Loose fit.
Larger axle size not as much movement.

Guess it comes down to the wheel bore size.
And ratios of fit for wheel movement in the
Wheel bore from the two different size axles.

My thoughts are telling me the larger axel size
With a tight fitting wheel bore size .
Would scrub the rail because of no movement in the
wheel bore ..In Relationship to the axle.

Don’t know this for sure or not!


What type of automobile can be spelled the same forwards & backwards?

Yep, that's exactly what happens. I just ran the truck down the track with the .087 axle and the speed increased.
