Thanks all, Muddstir, checked out your thread and wow, really nice work. Didn't see much detail on the drive but I'm figuring your using a center carrier with a sprocket and disk brake along with those CV axles... should work well. Depending on speed and weight you might want to consider front brakes as well.... you probably already have. It took me 2 years to build my 1st buggy so I understand how those big projects can drag on, but then yours ain't no ordinary project. I'm not planning anything near as difficult. Rear drive will be either the stock trans modded to accept U-joints (if I use vertical shaft) or an adjustable center carrier, sprocket, disk brake, 1" shafts (1/4" keyways), U-joints... (if I use a horizontal shaft) covers the basics. It currently has a 17.5hp motor, will stick with it or really would like to go with a horizontal shaft motor and a torque converter set-up. Need to keep the power low because of the 1/4" keyways! I've got cv axles and a pile of parts including a 2006 gsxr 600 engine and a cbr 600 engine, but alot of it is being saved for a 2 seat buggy that I will some day build. Have you ever looked at the site; MINIBUGGY.NET, lots of cool stuff.
