Well, for the sake of the argument, I have seen setups detailing Associated red, purple, gold and silver springs. All in all, one would have to buy the Complete TC3 Spring Kit which is in fact a $30 experiment. Not the end of the world, but still $30.

The Complete TC3 Spring Kit lists the following springs:

Two green springs #3941 12.0 lbs/in
Two silver springs #3942 14.4 lbs/in
Two blue springs #3943 17.0 lbs/in
Two gold springs #3944 19.5 lbs/in
Two red springs #3945 22.0 lbs/in
Two copper springs #3946 25.0 lbs/in
Two purple springs #3952 30.0 lbs/in
Two yellow springs #3953 35.0 lbs/in
Two white springs #3954 40.0 lbs/in

Anyone know how to come up with the lbs/in measurement? Has anyone ever measured the Tamiya springs to compare? What would the equivalent metric measurement be?

Thanks.

Not sure yet I am going to Florida for the office I thought on the same weekend and am just finding out it's on a different weekend.
If it all works out I will be down, the Track won't be open Saturday though will it?
I am assuming the Tanks etc. will all affect that.
I have been all the way up to Copper on the car up here in 40d outdoor temps and Seattle sunshine(wet) and the car is good with even that stiff. It wasn't on purpose I had just come from the carpet track and felt to lazy to change the spring

TamiyaCon is the 19th correct?

You need a ruler and a scale(weight) to do it.
You have to take a measured ht and load then compress and re-check the difference is the rate. It is a pain without the equipment to do properly
I did the old springs at an old place of employment and had those but the new rates are different. I would think they start at 7-8lb for red and go up to 15 or so for white it seems to be between the Assoc Blue and Silver.

I have been using associated springs on my shocks and have found that yellow fronts and purple rears are a good combonation. Keep in mind that this is for foam tires on carpet. For outdoors on smooth ashpalt, with rubber tires I find that the tamiya springs work fine. Depending on the track I run whites on the front and blue's on the rear with 60 weight in the front and 40 weight in the rear. But for carpet and foam tires the stiffness of the associated spring is far better than the tamiya spring.

just my 2 cents

Hey Joven,

Good job on TQ'ing prostock (again) Including my TQ's I think that the Evo3's TQed prostock for the last month haha (j/k I think). How's the track layout on Saturday? I'll be there tomorrow running my BL414M2 and may try the AE springs on it. I wanna run my Evo3 but I wanna lay some smack in the BL class (so far I've been getting spanked) before returning to prostock.

Guys,
I measured the Tamiya springs and Associated springs on a Materials test system that I have at work. I'll post the tamiya and associated spring rates when I get home tonight.

would putting shorter A arms (TA04-SS) on the Evo III, produce better steering?

any help would be appreciated.

Thanks in advance!

I've got a race coming up in 4 days and I've lost a part( #53500 cross pins). This is the pin and little cylinder thats part of the universal drive shafts on the rear. I've got no braking and 3 wheel drive at the moment. Is there a replacement part from other manufacturers that will fit to take me through the race. The part is on order but may or may not get in on time. I've got a TC3 spare at the moment, would using the CVD's from that be a problem? I think it might fit but have not tried at the moment.

If I cant get it I guess I could drive 3 wheel drive and no brakes =)

ecenshu: did you lose the cross pins only? i think you can use a 1.5mm L-shaped allen wrench. these L-shaped things come free with tamiya pinions and you can just cut them to the right length to fit the cvd. i think this will hold until your parts arrive.

These springs were all measured on a materials test system [all units are in in/lbf]. Listed are actual measurements from stiffest to softest.

Associated White 40.4
Associated Yellow 33.8
Associated Purple 31.2
Associated Copper 24.6
Associated Red 23.2
Associated Gold 18.8
Tamiya White 16.5
Associated and Tamiya Blue 16.3
Associated Silver 14.5
Tamiya Yellow 13.0
Tamiya Red 11.8
Associated Green 11.5


Joven - the associated silver springs are inbetween the tamiya blue and yellow.

I lost the pin, the cylinder that holds the setscrew and the setscrew. So I need basically 1/2 of a whole CVD =)

I have the dogbone and the drive shaft(The aluminium drive hex held it on =) )

well i just got home from the nats, and i have to say that it went pretty well.

i ran well enough in 12th scale to put it in the show, which is really good since i haven't run 12th scale in about a year. (thanks to ralph burch jr., travis schreven, andrew carwright, and fernando gorhdino)

and i finished somewhere in the C-main of sedan ...

sadly none of the team had spent enough time with the car on foam tires before the nats, and so as the grip changed throughout qualifying, other teams such as losi and associated knew exactly what to change on their respective cars, whereas we did not.

but i had a really great time, and made alot of new friends.
