I have decided to upgrade the steering wheel on my 310-8.I purchased a two spoke 15" wheel.Like the steering wheels on my 520 and 416h the plastic rim is slick.Wearing gloves in the winter makes gripping the rim harder.Before I installed the wheel I sprayed a liberal coat of rustoleum bedliner on the rim.The color matches well and you don't know its been done until
you grab the wheel.I am going to do this to all my other two spoke wheels.Cheap,easy to touch up and very effective.Luck,JAinVA
