Adapter not needed if?
2017 LSR has Sparco steering wheel. The Sparco adapter works with other aftermarket steering wheels. Like the flat bottom, makes egress easier.

NRG STEERING WHEEL
Product is very comfortable. I think it makes my drive more comfortable. NRG should have instructions for set up instead of guessing.

Heavy duty
Heavy duty with a very good feel to it.

NRG flat bottom steering wheel
Great steering wheel. It gives you more leg room in the slingshot, the steering wheel has a great feel to it, and it is much more comfortable and solid than the OME steering wheel.
