Once you get their and run you will know if your car is in setup pretty close.

Help;
Too many boards have left me out of parts. I am in need of front suspension arms (or sets) for the Evo 4, or LW suspension. If anyone knows a shop or e store that has stock, or has spares to sell, please let me know.
Thanks;

Narrowing foams

I'm having trouble fitting foams on the car AND maintaining a 190mm width. I got the 30mm rears to fit by moving the shock mount to the innermost hole on the three hole side of the arm and I used a red 1mm spacer. the prob is I can't get the front tires (28mm) to fit without spacing them out and exceeding the 190mm width. I was thinking of cutting the front tires down to a 26mm width and the rears to a 28mm width (so i could use the middle hole on the arm). Anybody else have problems like this w/ foams?

To cut the wheels, just use an xacto and use the bar that the cutter rides on as a steady rest. then fire up the truer and rest the blade on top of the tire once you have it lined up. My cuts come out almost perfect every time using this technique. The general rules to follow are:
*Wear safety glasses
* Make sure the sharp part of the blade is addressing the thing you are cutting, not the tip.
* Make sure tire rotation is going AWAY from you when looking from the top.
* Use the transit bar as a steady rest for the tool. If you try to freestyle it in mid air, you will never get good results and possibly injure yourself.
* Apply constant pressure until the cut is all the way through (don't stop).
* Don't be afraid. If you usually chicken out with machine tools, maybe you shouldn't do this
You can cut about .5mm increments off of tires using this technique and I have been doing it for years and still have both eyes and all of my fingers

If you do not want to narrow your tires, you can run X-X suspension blocks, that brings you in to 187 mm. X-A works, but sweeps the pins back and induces toe. If you run X-X and add
1 mm spacers behind the wheel, you still have to trim the steering arm (knuckle). I run the square knuckle, (alum) and have clearanced it to clear the wheels. Does anyone have another way to skin this cat, please post it here.

There is another reason I think doing the narrow/shim technique is the wrong way to go about it. By narrowing the hinge pins you effect the roll moment and by widening the car at the same time with shims, you have really changed the suspension geometry quite a bit. I prefer to use suspension changes for what they are designed for unless I have no other options.
With that said, I would like to try X/X in the front on carpet instead of A/A that I normally run because I think it would help the car in the transition... but that's another story

Nifty Transponder Holder
Made this transponder holder for my evo 4 using an old TA-04 front bumper stay and scrap polycarbonate.
Works very well.
Works very well.

Well ran the car last night for the first time with Rubber tires and the silver acn Tamiya motor ( I know but thats the house class we have) and the car was realy quick. I had a pretty good setup on but I could use a little more steering which I will will work on next time I run that class in about 3 weeks. I have a good starting spot and will work from their. My Tamiya A's were about shot but still had great grip so I will just use them again next time I run.

Hi Guys,
My apologies if this question sounds silly. I have built the Evo 4 but found that the diff and the one way has some play when shimmed according to the manual. The same goes for the input shaft.
Anyone else has this issue? could you share your shim setup.
The bearings from the kit is one of those that requires the most work that i have ever seen. They are literally packed with grease. not sure if you guys have a similar problems.
Cheers

Evo 4 vs. pro 4
I have a Pro 4 right now that I love. But I want a Tamiya to be my main car for next season. I want to get it as dialed as my pro 4 so I can go to the TCS races next year.
Has anyone ran both cars? I would like to know how similar they are since they both have the same drive train and basic set up. And another thing is, will there be a new high end Tamiya car out by then? It will be at least 8 or 9 months before i get a Tamiya so its probably anyones guess huh? Anyway, I love the looks of the Evo 4 and plan to get one eventually. Even if its called the Evo 5 by then. lol

When it is done right, there will be no play and minimal "backlash". If you are unsure of this word, backlash is the "mesh" or play between two bevel gears like in a differential in a full sized car. You want just a tick of backlash. Too much and your gears will wear prematurely and be jerky on the throttle. Too little (i.e. too tight) and your drivetrain will not roll free and again, you will get premature gear wear.

Bearing shields
Am I blind or something? I cannot for the life of me figure out how to get the shields off of the 950 bearings. I cannot even see the clip. Any tips?
