If you plea NOLO to the wreckless driving charge and the judge accepts you will keep your liscense. You will still get the same fine as if you plea guilty though.

Not sure about the racing charge, if it also suspends your liscense then you just need to hire a lawyer if you want to keep your liscense. You will not get off for all of it though, you'll still get fines, probation, and community service (which you can also pay off if you're time is worth more).
