Front / Rear of car, and Fore(ward) / Aft within the end of the car?

For example, "place a shim under the rear foreward hinge pin mount".

You need to give in BTW chassis right now is not 2.5 it's 2.25 (2.5 is an option chassis)

Chi Chi I should have known that you would be sniffing around. I do want to run the non norm chassis. I like the Photon but now everyone is leaning to that chassis. So now it is the 416 and Xray for carpet season.

If you are running anti-dive, you will get more initial steering and less mid corner. Compared to the 416X kit setup, adding 0.5mm extra under all the suspension blocks will maintain a similar balance but the car will sit much flatter through corners. If the grip is high, more corner speed will be the result, if the grip is low the car will slide around.
I normally refer them as 1,2,3,4 or you may refer them as toe 1, toe 2, or t1, t2.

Hi guy would really appreciate an answer on the question below:

the new TRF Li-Po chassis comes with either a one way spool or without. What do you use a one way spool for? I'm driving on asphalt so not sure if I need one?

cheers

Thanks for the replies CraigM & DirtyDog

I would say not, but its up to you. In slower classes some people use one ways and they can be very fast but realistically a spool will always be better in a race. The reason they do an upgrade with the one way is because with the belts flipped the kit one way won't work

Default lipo chassis

There are 2 different kits available (lipo conversions - not whole kits). They are both the same, except one comes without the centre oneway pulley and front oneway diff unit.

The part numbers are:

42181 - comes with oneways
42182 - comes without oneways

All other chassis parts and mounting parts are the same. Both chassis (main deck) is 2.25mm with a 2.0mm top deck.

42181 is available now (I have had mine since Monday this week).
42182 is not yet available.

It is personal preference and track type what conversion kit to get. Most tracks and people do not use oneways (front or centre) anymore. (except racers in Japan - hence why the oneway version is available now).

HTH.

Erick was your testing with the high diffs on carpet or asphalt?
On asphalt only.
I dont think the high diffs are a good idea on carpet, but I will check with my source what the team ran this winter on carpet.

I'm losing a lot of time having to slow down way early so the car "set" for the corner. Right now I have no shims under any of the susp. mounts, what result would putting the .5mm shims under the rear mounts(fr/rr) get me?
This was my question.

To lower the roll center you would raise the inner camber link position and lower the front arm. You could also lower the outside camber link as well.
Lower
• More on-throttle steering.
• Car is less responsive.
• More weight transfer at front of car.
• Better on smooth, high grip tracks with long fast corners.

Higher
• Less on-throttle steering.
• Car is more responsive.
• Less weight transfer at front of car.
• Use in high grip conditions to avoid traction rolling.
• Use on tracks with quick direction changes (chicanes).
This was the reply that I got, but it was converse to the post that you, Craig M, made prior.

I was trying to figure out if putting the shims under the susp. blocks on the back of the car would get me the effect I am looking for. As for refering to the blocks I think it would easier to refer to them as f1,r2, f3, r4 going from front to rear on the car.

No, Tamiya does not make a gear diff.

Artworks discription is what I find as well. To put a shim under the suspension bridges front or back will loosen that end of the car, less grip.

How about calling them (from front to rear) front, mid front, mid rear, and rear, I think its pretty self explanitory.

Boy I hate this car, I have a worked over 416, not a WE or a X, I have shelved this car for about 4 months now, due to a disagreement, last week I took it out, put in a older speed control and a used up motor, proceded to turn more consistant laps and only a 10th off my best time with the car I have spent a lot more time on. They are both great cars, but my 416 is such a tease.

JCarr, what is it your trying to make the car do??
