    Ah, so you're a bike guy, too? I actually have five bikes, and the Fuji is the only one without drop bars. It's a 1984 Del Rey I bought on Craigslist for $90. It needed a lot of fixing up, but it's something I enjoy doing.

    You're right, the saddle is a Brooks B17. The downtube shifters are the stock SunTour Power Shift units, which are the nicest friction shifters I've ever used. The handlebars are Velo Orange Milan. And no, the brakes are not stock. The original Dia-Compe calipers weren't enough for me, especially with the shorter brake levers on the new bars, so I upgraded to modern Tektro dual-pivot calipers. It stops on a dime now.

    Talking about the loudness of the Mirage, the Mirage is a loud car. Not if you're being super gentle it idles actually quiet, but revving it, wow look out. Vroom! One of my coworkers thought the car is a diesel.

    On the musical side of things, I'm a 24/7 music person, so not sure if my Mirage's stereo has actually ever been off lol.
    My area is crazy expensive compared to where I used to live (Georgia), but it's cheap compared to California. I live in an apartment, but most of the houses nearby are $500k and up.

    It's true, the Mirage's three cylinder is hardly the smoothest engine out there, but I'll put up with a lot of vibration if it means 50mpg.

    I do enjoy music, but only in an otherwise quiet room. I like long walks with the dogs in silence, or long quiet bike rides. My favorite button in the Mirage is the one that turns the radio screen off.

    Oooh, bike porn.

    Yes, I love bikes. I used to commute by bike for years. My Mirage is a compromise.

    Try one of the Brooks springer saddles, such as the B-67. Those handlebars (and your tush) deserve it. More about it here A Comfortable Bicycle Saddle and here Saddles with Springs

    I'm going to guess that you are familiar with Sheldon Brown? He was a big inspiration for me.

    Were those forks pushed back? Maybe it's the camera perspective.

    Fenders are not required in Phoenix.

    I've learned a ton from Sheldon Brown's website! I love his practical, no-nonsense approach to everything. So much of bike culture is just hype. I do wish his attempt to bring sensible spelling to "derailleur" had caught more traction.

    I honestly never considered a sprung saddle. I bet one would be pretty comfortable on the Fuji, but the B-17 is perfectly fine with me. It's the only Brooks saddle I've found comfortable, and only on that bike, with its fairly upright seating position. I tried a Swift on one of my fast bikes, and it sure looked nice, but I was never able to get comfortable on it, even after close to a thousand miles. I went back to a $10 vinyl-and-foam saddle, and was happy again.

    The forks are straight. The camera angle and a slight turn of the bars makes them look off in that picture.

    I consider fenders for my Fuji, but like you said, it would be purely for looks here, so I decided against them.

    That's a great writeup. It looks like someone skilled could pull the entire interior out in an hour or so.

    Which, in my mind, means fixing a side impacted Mirage easier than the shops make it out to be.

    Hi Scratchpaddy

    I am going to sound dampen and insulate my car soon. I have a couple questions for you.



    For the sound dampening material, I'm looking at going with a cheaper alternative. What are your thoughts, if any?


    You used UltraTouch to insulate the floor of your car. I am concerned the cotton will absorb moisture coming through the carpet. The carpet can dry out easily by itself, but with another water-absorbent layer beneath it I think this will cause mildew or mold or smell problems. The alternative I am looking at is a closed-cell material (hydrophobic). This stuff is lightweight and thin, but definitely not as insulating at the UltraTouch. The hydrophobic properties outweigh having a little less insulation, in my opinion. Being that I live in Wisconsin, snow can cause more moisture issues than rain. Thoughts, if any?



    This thread is packed with great information, I'll definitely be using this as a guide. Thanks!

    Great write-up and nice pix!
    Did a similar one about five years ago
    https://mirageforum.com/forum/showth...bitumen-tiles)
    and this came straight into mind:

    In your second picture of post #3, above the top shockabsorber nut and below the seatbelt roller-up thing there is a "hole", and also a second hole slightly above and forward of the seatbelt roller-up thing.
    Through those two holes you can access the inside of outer panel which rings like a bell. This proved to be an ideal place for reaching through to stick some asphalt tiling to the insides of the outer panel.

    While doing the job, I took hold of the opportunity to apply some wax cavity spray on the inside seams of the rear wheel housings and the inside door seams after sticking on the tiles.

    What wax cavity spray did you use? Iíve been looking at doing this when I take apart the door to deaden/insulate and upgrade the speakers. This wax cavity spray is a bit confusing. Does it spray out liquid and then immediately harden into a wax?

    Look up a product called Fluid Film. I've seen it as a DIY in hardware and auto parts stores. It's available as a aerosol spray can, and individual cans (pails) along with specially designed spray equipment for treating more than what can be covered by a spray can.

    The stuff is basically wax disolved in some sort of a mineral oil based solvent similar to gasoline. It flows freely when it gets sprayed out of the can, and gets into the smallest cracks and coats whatever it touches, but quickly dries and becomes a pliable wax. In these parts there are literally dozens of makes and you can buy it at almost every grocery store. It costs about the equivalent of $2 - $5 for a half quart spray can. Two cans are enough for the entire car. You do not want to spray the entire door from the inside, just doing the seams will do. No glue or anything else will stick to any surface it has been applied to, so first the tiles, then the wax.
