View Full Version : Micro RS4 Rally ideas...

This is a thread that I'm hoping will eventually develop into something that will lead to being able to run an RS4 on an off-road rally course.
Problems:
- Suspension travel (front and rear)
- Belt exposed (a guard would need to be made, out of lexan or something)
- Rear diff & gears exposed... they'd need a cover as well.
- 300 size motor, with enough torque to get the wheels spinning to induce dirt drifts...
- "Rally" style tyres will be needed. Any ideas?
Maybe a new chassis would be in the order... I'm not sure though. I'll start sketching and thinking during my classes this week. If anyone has any ideas, i'm game to hear them.
OH, and a definite requirement would be either the WRX chassis from RADmotorsport, or the 206 shell that I saw floating around earlier... who makes it?

on the front youd probably need to mill a custom front end for custom lower a arms to increase suspention travel and ride height. then something on the rear end (think taimya). with time and lexan you could enclose the belt and maybe get a bigger belt and put bearings to raise up the belt
just rebuild it from the ground up with aluminum, enclose the motor, belt, diffs, all of that stuff in aluminum that could clip to the body on the sides to help keep dirt out, but you would need beefy shocks and wider/longer front and rear ends

Wait a sec... why not use a pan chassis? That would keep most of the car protected, and maybe I can modify the rear end to have some kind of suspension. *think think think*

I have a Super Nitro Rally...and youll definetly need a new chassis...no carbon fibre crap will sustain the stress...also some tires with knobbs,prolly have to have em custom made...custom made suspension arms cuz nobody is gonna make some for mini,just make them out of wood,preferably oak or pine,and have em almsot a 45 degree angle...then the motor,cover it with some homeade design is all i can really suggest,try making it out of a plastic water bottle or summin and just tape it on every time,althought this wont let your engine cool i dunno how to fix that,but if you put your mind to an idea youll figure it out...:D

I disagree on the stresses... People abuse their Micro RS4's already with lots of success...

It's just a matter of raising the chassis and protecting some stuff... I guess it's kind of an obsession of mine, i'm almost done my Mini-Z rally mod.

#73407 is the part that needs to be modified to allow more suspension travel.
The lower arms need to be lowered towards the ground to heighten the suspension...
Does anyone have a spare one of these that they'd be willing to part with for the better good of off-road wantin' micros everywhere?

g-oooooooooooooooooooooooooood damn that ****ing micro is faster than my super nitro rally...but if it hit my snr like its hitting those curbs id demolish it :D...

Okay, I'm interested.
why start with a short belt from the motor and add a couple of smaller ones to reach the differentials?
then you would only have the two small belts exposed and rigging small tensioners would not be to hard.
Let me work on this a little bit, I might have some better ideas for you.
but beware, most of the stock chassis will have to be replaced.
buy the way, this could be lengthened to become an off road truck (like a CORE pro2 or pro4 type truck) as well

the ARM pan was the chassis of choice, considering it's practically one big peice, and can be modified to whatever use needed.

yall really should start with just the chassis and if yall kknow somwone who does milling get them to make a shaft and find some way to make the car shaft driven

Yeah, but I'd rather use the existing belts, rather than redesigning everything.
I basically need to modify the front suspension, and then work out something for the rear.
How bout this Independent Rear Suspension for a rear end?

Ive been waiting for my micro to come in, but ive also wanted to convert mine into a rally car. Ive been thinking up some stuff and this article may give you some ideas building rally cars (http://homepage.virgin.net/shalco.com/seat_build.htm) I doubt that making an independant rear suspension is going to be easy. but as for the tires, would it be possible to stud them wih something? maybe some very small screws, and then glue them in? I dont know if that will transition well, but i saw this episode of "monster garage" where they studded a chevy impalas tires when they were making it into a zamboni, and it seemed to work well.
also heres another good article i just found article 2 (http://www.rccaraction.com/articles/rs4_tuningguide.asp)
how do you think a titanium chassis would work? or would that be overkill.

Monster Garage rocks! I love the mustang lawn mower :) gotta get me one of those. But screws maybe, or tacks never mind im thinking ice..
I have also used Kennex"Spelling" tires once to lift my micro off the ground. It looked pretty sweet, was about inch or so off the ground. Has alot of traction in the dirt to, was to fun until all the wheels spun out :) . Have Fun!

Bwahahaha, my favorite would probably be the Impala SS Zamboni... before they modded it.:( It is a pity because that was such a beautiful car.

Could you mount another front assembly on the back? Also put some hinge pins on the bottom arms so they can go up and down.
only with major mods to the assembly and the chassis

Honestly I think the car is too small to successfully negotiate large size bumps, etc. Unless you groom the dirt surface so it is in scale with the Micro it will have a hard time. 1/10 has larger wheels and tires, more suspension travel, and most importantly, more weight and a longer wheelbase. All of these make it more stable as a rally car. Good luck though :)

I'm currently out of a job :-( (and in school, which is the reason I quit the job, and the reason I don't have time)
And regarding that person's comment above, the idea is that you can have a mini SS circuit in your backyard or back lot that you could groom to make sort of a scale rally system. I've been trying to figgure out a way to work the rear for suspension, and the best idea i've heard yet is to use another front suspension in the rear...
... now to find someone to send me a front assembly, and i'll be set.

I knew someone had thought about this... Has there been any progress?
I'm getting a rtr rs4 this weekend and my thought was to make it a rally car, or at least look like one.

so far no news yet. im waiting for news on this micro rally. it suit better for my hometown's street road with uneven surface :)
have you guys check out the new kysho mini z land cruiser? it got a superb suspension set. maybe can get the idea from there.
from what ive heard/read the RS4 is basicly a rally car, with the only change needed being tires, i wouldnt know, i drove the engine off of mine :D even after the red locktite the four screws came out and the engine went one way, the car went the other lol

lol.... sound fun :)) but i think rs4 is not a rally car as you can see from the suspension set up. it is to short to be a rally car. need more ground clearence and longer suspension travel in order for rs4 to fly over bumps and etc... :)
i ve tried sticking a mini tamiya monster truck tyre onto my hpi med tyre and it manage to increase the height of my micro by double. with that set up i can easily travel up my feet. or any small obstacles. not only that i can drive on uneven road. but the tyre is rubbing agaisnt the front bumper when i turn either to left or right. guess have to do something about it :)

You need to put the longer arms and larger shocks on the RS4 to make it into a rally. Once you do that its basically the same as the RS4 Rally, aside from some other bits and pieces.

There seems to be some sort of misscommunication here...lol. Im talking about the REGULAR RS4/RS4 2 sport not the Micro. It was in response to j_wj's and rpnick's posts:p
Granted a Micro rally would be pretty sweet, but there would have to be MAJOR changes to it. It would almost be better to make an entirely new kit and maybe use some Micro parts.
im with you there Neo, but im pretty much out of racing, havent fired up either my storm, or my mt in a month atleast, and i still have to finish breaking them in

I have got micro rs4 tires for offroad use sitting on my workbench right now.
I'll have some pics up next week.
Oh and I have an idea for the front suspension. Yeah if you dremel out the lower arms and replace them with an extra pair of upper arms (with the ball cups dremeled off. the arm will stop a bit past the hole that has the hinge pin go through it.) with an extra pair of hinge pins going thru them, then it should work. All you would need to do after that is dremel the edges of the chassis down so the arms are able to go under the chassis, and preload the shocks (with fuel hose under the shocks), and you'd have some suspension travel! :D :)
Only problem is I can't try this out on my micro (don't wanna ruin my great car :) ), so I'd have to do this on some extra peices.
let me know how it goes!

I've done that front suspension mod. The only problem is the belt side lower a-arm will hit the front diff pulley. I tried to get around this and ended up modifying the a-arm so much that it ended up just breaking. I will need to use the left side upper a-arm as a pulley side lower a-arm for best results. The front diff had to be raised as much as possible so the arm could clear a little bit more. I am now trying to get this incorperated on the rear so I can keep 4wd, I have a pretty good idea on how im going to do this, just lack of funds keeps me from completing. I will post all pics once im completed my fully independent front and rear suspension.

cool tyres you got there hawk_196. mind to tell us where you got it? i ve been trying to look for 1/18 or 1/19 scale tyres or wheel to be fitted onto my micro. so far no luck :(

A little Nikko POS was the donor of those tyres. They suprisingly fit fairly well (back tires are perfect but the front tyres overlap the rim a little.)

reverse the current design. you would need a aluminum lower bulkhead. bend the lower arms up about 1/8-1/4 inch. take your car and flip it upside down. basically build the thing like that. on its back. granted you would need a pull type of spring for your suspention but atleast its a thought. the more you bend the lower arms up the greater your travel would be.
