  • Carrera Ford Capri Rs 3100

    Carrera Ford Capri Rs 3100,
    Runs very good, not quite as well as my Porsche in this picture, but tuning is preliminary, PG PGT-20128LMXD shore 40 compound tires (wheels/tires not yet trued), pulled both magnets, added some tungsten putty under the rear axle. Needs wheels/tires trued/glued, some weight midship area, softer braids to help keep front end down. I massaged stock braid for now and helped a lot, nice runner and looks great! Pulled the mirrors, the angle the mirror heads are at looks like they are on the wrong side of the car, but they only go in one way, looks better without them anyway and they're bound to break. The headlights are better aimed than some of the Carrera cars I've got that shine upward and blind you, these are actually kinda useful for 'night' driving too.

    Will update this as I do more tuning and running!

    It's got different rear wheels than I've ever seen, bunch of ribbing in the center instead of a single solid rib, kinda like a Slotit/NSR air wheel but not really. They are chrome plated instead of painted like all my other Carrera and Scalextric cars, should I lightly sand/scuff the bead area before gluing and truing the PG tires?

    The motor and rear axle assembly has more side to side wiggle than some others, after adding weight under rear axle, E6000 on the motor to stop the wiggle. Included two pictures pushing rear axle to each side to show this play, much easier to see in person.

    I replaced the rear end Slot it crown and 12x13 racing wheels CBD. PGs or Quick Slicks.Take the rims off and add a spacer on each side.

      Good idea thanks, but trying to keep this one stock-ish and lower budget plus less gear maintenance with the nylon gears vs metal/plastic such as Slotit, gotta keep the black grease on those or they self destruct...ask me how I know lol.

    Sanding is alway a good idea. Removing excess mold flash does assist the tire fitment if there is flash mold present.

    You might think about a Tire Razor for your future sir. Well worth it.

      Agreed thanks, I've got a Tire Razor that I bought 3 years ago and now have use for. Our now out of business local track had a tire machine to build/tune cars with.

    If you plan to keep the stock rear axle assembly, you'll have to place spacers between the bushings and the wheels.
    SCC carries a variety of sizes for spacers. And they're nylon, so cutting them will allow you to place them between the wheel and bushing without having to remove the wheel. Just snip one side with a pair of dykes, and with the axle assembly removed, slip the spacers onto the axle. You may have to try a couple sizes of spacers to get the right setup.

      Ah great idea, forgot I've got a pack of the blue plastic varying thickness spacers and yes a careful snip to one side should make them easy to install on stock axles. This should also help the gears and motor shaft bushing to last longer too.

    Spent the night before New Year’s Eve racing around with a friend and this Capri is quite nice driving with PG urethane tires, magnets removed and a bit of weight added! Headlights have good aim so that they don’t blind drivers like some others do, if you like it, buy it!

      SlotCat, the rear tyres are quite wide. Just wondering if you know the width and id and od of the original tyres thanks.

        Yes they are, I don't recall but will check. These tires I posted above fit very well PGT-20128LMXD shore 40 compound tires.
