No need for a diff on off-road race cars. The gear ratio is probably pretty close to what you need; most Baja cars are running anywhere from 7:1 to 10:1 with a CVT. 4.85:1 is only for bike powered mini buggies and is in no way comparable to a Baja SAE car. You can do the calculations pretty easy to figure out what gearing you need for a top speed of say 35 mph. Or look around on here, I posted a spreadsheet that does the gearing calcs for you several times before.
