thats one of the collest home made ones i've seen so far, im most def going to build me one of those from the instructions you posted. thanks mate
one thing i dont like about yours, is that its up too high for me, my car seat sits really low to the ground, like my legs are barely bent when my feet are on the petals, and i feel comfortable sitting that low to the ground, so when i build mines, i will just subtract a few inches from both the steering wheel column and seat height.
