GTM Week 3 update: Steering Wheel/Roll Bar Question

[GTM_Vet]

Had the car 3 weeks now and am sorting out the tune with my tuner we pretty much have it dialed in few more data logs and she'll be right! Over all an amazing car very fun to drive (what little I have driven it). Besides the wheel that comes with the car what other wheels you guys using? Car came with a yoke wheel which is kind of cool but I'd like to have a different one. Show me what you have and bonus if anyone can tell me if I were to order what's the best size. May do a custom order. Also the car has a digital rear view mirror and I need to find a better way to mount it. Currently is use's rubber straps wrapped around the bar in the center and its not in a good field of view and no way to angle it towards the driver. Ideally Id like something that has a clamp that goes around the bar and can hold the mirror and secured that way anyone have an idea what would work?

Also what is the roll bar size that runs across the front windshield?

thanks!
