    Lightbulb Slash 4x4 - Project Slash WRC

    First Traxxas truck and first Traxxas forum post.
    This is my Slash 4x4 that I'm gonna turn into a WRC rally car (street and hard gravel).
    I'm hoping for many comments and tips!

    Original Traxxas Slash 4x4 VXL



    All new Alu Traxxas wheel carriers front and rear



    Wheel carriers installed



    Cooling fan



    From the left: 21t - 18t - 13t



    MIP X-Duty CVD kit


    T-Bone servo protection



    T-bone closeup - filled the space between the prop-shaft and the chassis with velcro.



    Homemade mudflaps



    And now to the transformation...

    1/8 GT2 Rally wheels


    When new parts arrive, new pics will be posted!

    Get some rpm arms all the way around, get some LiPo batteriies , one 2s and one 3s I recommend 5800mah.

    And your 1/8 th scale tires won't be good on gravel only on road. Unless you planning to switch back and forth.... I would get the proline trenchers or badlands on desperados. They are 2.8"s

    Thx for the replies.
    Im going to use a Subaru impreza body from tamiya 1/8 scale.
    Rpm arms is going to be the next uppgrade!
    Im still waiting for my 3s lipo.... I live in sweden and all the parts live in the US (mostly)
    And the wheels and tires.... Well, primary the truck will run on the streets.
    Loss of traction is just fun on a bashing level
    I have been looking around the interwebb and this rally mod on the slash seems really rare.
    I think that i will rebuild the original shocks..... Hmm not sure.

    Try to fit e-revo shocks on. They will look awesome. They aren't expensive either!

    even if they are longer as long as they compress far enough is the big issue. you can alsways take it aprt if your rebuilding it anyway and put a piece of nitro fuel tubing inside to limit the up travel. once you get it where you want it at then you simply fill it with your fluid of choice and leave the tubing on there. learned that with my old t-maxx
    there's no life like a LOW LIFE!

    Well.. I want it to ride low.. but not to low.. Not very specific but you know
    RALLY HEIGHT!
    But hey, great tip with the nitro tube! Think i'll go with that!
    But to the fluids.. I have absolute no idea what to use and where to get it.
    I don't really want to go redneck style and put ordinary brake-fluid or something like that :P

    I have spacers on right now but I want lower ride height. And as I said above.. think I'll go with nitro-tubing

    And for the Tamiya Impreza body.. I simply don't know. Still waiting for the body to get here. So fingers crossed!
    I will post pics of the body as soon as it gets here!

    This is the body!

    Btw, do you have pics/posts of your rally Slash? Would be fun to see

    ^^^^^^^^^^^^^^^^^^^^^^^^

    i found that using stock shocks worked just fine as you will get a small amount of sag anyway. but you will have to wait and see what is needed for the body you get. i was using the kyosho one. the spacers i used also stopped the body hitting the ground under hard braking. i only have this picture which don't show anything really. i even used a Aston martin body without the need for spacers inside the shocks. i would of had more pictures but me and photo bucket weren't getting on to well when i done mine lol

    That looks AWESOME!
    Just what I want to do with my Slash!
    Yea, you are probably right, I will modify the suspension after I put the body on there.
    I don't want to drag the body during acceleration or braking. So it all depends on that!

    if you run just on road you could stiffen up the shocks for a really low body but if you try to go off road it will just bounce around to much. i think the wheels i used were jato ones and as you can see they fitted the 1/8th shell well.

    The Jato wheels looks perfect for onroad and "offroad"(gravel etc) and they can handle SPEED as my 3s Lipo is on its way. Thanks for the tip! But my GT2 wheels looks very hard and so on, but really they are soft grip tires, perfect for onroad!
    So maybe more offroad tires than the Jato ones? But still the 2.8" rim diameter. I'm gonna hit the rc webbshop now and see whats available! Rally rims with offroad tires!
    To bad you don't have more pics of your rally truck!

    im not really into taking pictures of my cars. and all i really did was make some front and rear body mount extenders that used the original traxxas mounts. and fitted the spacers to the shock shafts. i do have these old pics of the mounts they were the first test ones i made but they worked so well that i never built anything better.

    Great photos! I think this is going to be an easy bild
    Im not that nervous about fitting the shell and about the ride height anymore.
    And the slash 4x4 must be the best base to bild a rally car from.

    Looks really low but doesnt the suspension have to be really hard so you dont bottom the car out?
    Thanks for sharing your build!

    Usually in rally the cars use belly pans to help with bottoming out and it certainly doesn't hurt our cars..shock stiffness all depends on the type of surface your running on the higher the grip the stiff shock you can run...

    Turns out that the body I was waiting for doesn't exist any more...
    And it's nearly impossible to find a nice looking 1/8 rally body... Kyosho has a nice one, but it's out of order...
    So.. found a plastic company in Italy.

    What do you guys think about this one?

    Based on googling I've done lately, these were only rally bodies I've found. But it looks pretty cool. Have you checked prolines new focus body?

    Hey 2Late.
    Awesome site! In sweden and all!
    Where Im from

    BUT... I says 255-260mm wide.. The slash is 296mm.
    But if length and wheelbase is correct I think I can fit the wheels in with a sligth negative camber
    To bad its not wider!

    Right now I'm waiting for my Traxxas 17 hex adapters. So I can fit the Gt2 wheels.
    Then I'm going to shorten the width by drilling new holes and cuting the a-arms.
    Then buy and put this body on! -> http://www.rallyclassics.se/QsportS1E2.html

    Pics to come

    Quick update.
    I got my wheels mounted.. well three of them. I got my Traxxas 17mm hex adapters today.
    Still waiting for my ball bearings for my back wheel. Broke two of them, and I'm blaiming the MIP's..
    There is no "pin" that holds the hex.. and the tiny skrew that should hold it brakes everytime. With och without glue..
    So.. original driveshafts on right now. I'm going to drill some holes in the MIP's so I can fit the pin back on.

    Body and other goodies on it's way!
