Gonna have to extend the rear frame another 8" to keep the engine as low as i want it. The 28" atv tires im gonna get will make up for the added length, and i will build the roll cage to make it look legit. The buggy will be about a foot longer than stock. If i don't extend it i will have issues with the engine being mounted high and hitting the seat and main roll cage supports. I have an end result in mind that will be functional and look cool. As far as turning radius, Im planning on putting 22+" tires on the front with 12"rims. The 400ex hubs make the front 3 1/2" wider. I will grind down the stops as long as there no rubbing issues. Im thinking the bigger sized tires will give more top end, from what ive heard 50mph is tops with the stock oddy gearbox. plenty fast enough for me...Should be good with this setup.
