Awesome build. I've purchased the plans and reviewed them, and I'm getting ready to buy parts to build one of these for my 8 year old. Hoping to have some of the basics sitting under the tree like wheels/tires, axle parts, steering, etc... to get us started.

I'm curious about a few things:

* Do you ever wish you had reverse (I'm considering adding a forward/reverse gear box as well as a torque converter)
* I'm considering going with 20x10-10 wheels/tires rather than the 18x9.5-8., Do you think I'd run into problems with steering (maybe easily modded by lengthing the nose and extending the arms further out)? I may also go with a 22"x7" tire up front on a 12" 4on4 trailer rim, and also planning to update the spindles to the 3/4" ones from BMI.
* Did you buy your spindles or build them yourself?
* I saw that you widened the chassis cab area, would you also consider lengthening it? (I doubt I'll be able to drive this thing at 5'11" 250, but I'd like my wife at 5'8"/125 to be able to ride in it comfortably).
* Is it possible (and are you willing) to share the plans you drew up?
Yes, I am not sure what route Im going to go. I may grab a box out of an ATV or something that can handle the power
You will have a harder time turning at low speeds the larger the wheel
The spindles are from BMI karts. Get the 3/4" version and buy the sealed bearings!
Not for me I'm 5'3" LOL
I can send you STP files

What size tires and rim did you go with? looking to start this myself next week, just bought the plans and the square steel

Ok great thanks! so are you saying you used 3/4 bore 4x4 for the front? i was trying to find those, ill keep looking. What did you use for the rear axle itself and also the rear hubs if you don't mind, and thanks for the info!!

So i found the axle and spindles. They should be here this weekend. The only trouble i am having is finding the bushings. They should be 5/8 ID x 1in OD x 2in length, correct? where is everyone finding these? Ebay wants $20 a piece....

The bushings for the A-Arms, for the front suspension, the 1" tube to connect the upper and lower control arms to the frame.

Meh you dont need bushings there. Just run a 5/8 bolt, drill and tap the tube for a grease zerk and call it a day.

I havent run any on mine and its still solid. I meant to do the grease zerks but I am lazy.
