  • Will, I don't know what your stock car looks like or has on it but Joe B. has the BMI chassis and he was a good 3oz lighter than my stock tub and mine was at 51.5oz and besides when you go to big races you just have to add weight anyway. Also I think that the car is [U]at least[U] just as stiff if not stiffer as the stock tub. Plus it looks killer and performs better.
  • Geeeeezzzzzz Jason, ya beat me too it!
  • damn, we even get guaranteed? liek if i dont Like it. Wow. Lol. If i Get it i Wanna Get My Team carved into it hope jason can Do that for me. especially for carpet u said its stiffer . Also Jason ima Pm u Ask a Question. check ur Pm.
  • Jason - I found that mine is still over weight 1545 grams.

    I'm running the steel diffs, so that may contribute to the weight.

    I noticed that you can twist the car side to side - in effect tweaking it. I haven't run it on the track, so I'm not sure.

  • do you have 2 or 3mm upper brace?if it twists a little it wont hold it.that is a problem with stock.you can slam the boards and it doesnt tweak.are you running carpet?
  • yes,steel outdrives are much heavier
  • the bmi chassis with motor mount and assembled with hardware and standoffs is lighter than the tub by itself
  • Jason - 3mm upper brace, running on carpet
  • jason u got pm
  • Hey Jason are you busy, I just tried calling. I'll try again in a minute.
  • Hi,

    wdm80:

    running steel diifs will make you overweight. I run lightened steel diffs and I still come in heavy for mod class.
    for diffs just as strong but lighter I run Hardcore Alumium diffs. you might have to work on the cases a little but it's well worth it.

    chassis twist:
    yes you can twist the chassis with the 3mm top deck. but the forces implied on the chassi/top deck when your racing are no where near the pressure you are using to twist the chassis. even in mod/foams/carpet. I have found that a modded tub TC3 will take a tweak with a moderate hit. so far we haven't had a tweak problem with the B.M.I. chassis with either top plate on carpet. we mostly run stock and some mod (7x1)s we will run the 3mm top plate on med to high bite tracks.

    if you have any other questions please e mail me at [email protected]

    as for being wimps..I never wear a coat all winter long. last night it was 1 above with a wind chill around -40* F
    also I'm a transplanted Canadian..... so I know about winters.

    Stephen B:

    Hi,

    Thanks for posting you thoughts on the B.M.I. chassis I am looking forward to running ours on carpet soon......as soon as I get a weekend off work.
    What body were you running??? track size??? Etc??

    Thanks
  • Tim, I run on a Very smooth asphalt track that is I think 140x70 I just got a Mazda 6 body and it runs great (more steering than stratus 2.0 but still just as planted). If you are talking about running the x-ray on carpet it will be awsome, that thing is as stiff as a rock (and i mean that!! ) which makes the suspension more predictable and to me smoother to drive.

    Maybe after you get it you can post your setup up b/c this is going my first year with an x-ray on foams at the snowbirds and I will probably need a starting point.
  • Oh and I forgot, those of you who run X-ray evo-2's what side do you have your servo mounted?
  • right side i have mines stephen
  • i Didnt want scracth my Evo's chassis on asphalt i went outside to break bearing in a little bit. i Put the Cars height up. But I didnt see a Bump and car flew like 2 feet and i scratched the bumper
