Then I used some key insight from my friends that ride motorcycles and discovered that they are motorcycle mirrors and I could get them for $10 each. Best of all they even fit in the stock bolt hole. So everytime they break I just replace the whole thing, it's just one bolt. Emgo 20-25172, Emgo 20-25171. They break just as often as the stock ones but they only cost $10 as a full assembly and I think they are higher quality and more adjustable.

    You could still have them get out of whack if they get hit by tire chunks or rocks or if they are lose. They're not exactly huge and easy to see through either.

    I buy them on Ebay and I keep spares at the track. I also cover them in 3m foil so that when they do break they don't fall on the track.

    when you say 3M foil you are talking about the glass part of the mirror right?

    Laguna Seca by Darin Polsley

    Darin's laps were an inspiration for me since I first found them out there in the public. I think they belong in here for the record, no better material for our archive!

    As far as I know these are the stats. I believe Darin tested and helped develop the SRA with TMI. See https://www.ariel.club/forum/viewtopic.php?f=22&t=12788. He set the records for Atoms on a number of tracks and those are the ones you see on the TMI website. He also won NASA's Thunderhill 25 hour in Spec Miata and got 2nd in Spec Miata class championship. Anyone that's into racing knows those are some of the toughest races, lots of skilled drivers and no politics and money to get in the way.

    The car is an Atom 2, with custom aero, 225/275 Hoosier A6 slicks, and the UK spec Type R engine.
