    Rustler rear spoiler?

    Will removing the spoiler make a noticeable difference in keeping the front end planted at higher speeds?
    I can feather the throttle to keep it down out of the hole...but once it gets wound up it's still wanting to lift the front end.

    I prefer to use a metal rollcage for speed runs. That eliminates parachuting. And I do think a wing will slow you down for sure, due to the extra drag. I don't know about raising the front wheels.

    If you have a front rpm or similar front bumper, you can turn it upside down for added downpressure on the front end to keep you planted.

    I don't have a front bumper right now...but will be adding a rpm bumper soon.
    I might try it w/o the spoiler. Might also try adding some weight on the nose.
    I'm not trying for top speed...just want more stability at higher speeds.

    Out of curiosity...what cage are you using?

    Integy... and that's the only integy product I will use.

    You can tape lead to the front bulkhead area, or anything else that'll add weight to it. I'd start with 2 ounces and go up from there.

    You can also move the shocks to the upper inside holes and lower outside holes to drop it down a little.

    Removing the rear wing on my Rustler never made any difference in speed runs. Removing the entire body however made a huge difference.

    If you were talking about a Bandit on the other hand, removing the rear wing makes a huge difference. With the wing in place the car was limited to around 64 mph with the optional speed gearing. Removing the wing brought the top speed to 70.9 as recorded on radar. With the wing removed the car is also much easier to bring up to speed. The issue with the wing is it makes so much rear down force that the it pushes the rear of the car down and angles the front of the chassis upwards basically creating a wing that lifts the nose off the ground.

    Like I said though...not too concerned about actual speed...just with higher speed front end lift.
    I'll probably try weights first.

    I have an 8oz piece of steel that I velcro to the top chassis plate for speed runs. Also, I have the STRC extension kit installed. Those two things keep it very planted at high speeds, even with the body on.

    A steel pate and Velcro seems like a good idea.
    Thanks.

    If you can add some anti squat it will help as well. The problem is the only way I know to add anti squat properly is with an aftermarket transmission like the FLM that has detachable arm mounts. You can then use anti squat shims under the arm mounts and this will help keep the front end down.

    You know what?...
    I just took it out for a blast in the back yard with a 3s in it.
    Right now I have big Trenchers on the back and small Dirt Hawgs on the front.
    Half throttle wheelies all the way across the yard is a blast.lol.
    I might leave it like this for now.

    Rear spoilers in general for both buggies and trucks help with overall high speed stability not just the back end. You may find that the front end stays down but the rear is all over the place.

    For speed run purposes, I would leave the spoiler away. Putting more pressure on the rear end behind the rear axles will also make the front end lighter. When it is right above or slightly in front of the rear axles, there would be only downforce and no front end lifting.

    Since the relatively high speeds of these little cars, the effect on the frontal area is relatively high (more drag).
    I never did serious speed running with a Rustler body, but using a Bandit body you would have a much more stable and faster car without the wing.

    oh, I thought the fronts were 2.8's and the rears were 3.8's. I'm just used to the 2.2 buggy tires.

    We are probably about to buy 2 sets of Stampede 4x4 tires/wheels for both of our Rustlers...just to bash around with.

    Is anyone familiar with on road cars to know if there is a front spoiler from other cars that one can attach to say the rpm wide bumper flipped over? There are two round tabs on there one at each end that are just waiting for a front spoiler/air deflector.

    I'm 99.9% sure that they are 2.8" dirthawgs, the dirthawgs are just lower profile. I own both of the tires he has.

    Hmmmm, on closer inspection, it does look like he has the same rims front/back. I wouldn't know if they are 2.8s, they just look smaller and I'm taking dcfox's word for it. But it also could be a typo... don't know. Hopefully he says something, because this conversation could go on forever...lol

    Ya, it's not a big deal. I hadn't realized that this thread is 6 years old either

    Yep I agree, but dcfox was active 4 days ago, so there is a slight chance he will shine some light here...
