Thanks in advance.
If you want to use standard springs from your current selection you could try the 1mm drop down collars for the shock bottoms. For asphalt you don't want to drop down too much anyways- not as much as carpet I mean. You could use the new springs of coarse since they seem about 3mm shorter but there isn't much tuning selection compared to other regular springs.

The new package of all white springs is the same as the tuned hard spring set. The whites are a special set done for Japan only until now. At least that is the way I hear it............


I`m using the standard on road yellows and I run 6mm rear height and 5.5mm in the front with no problems on asphalt.

Sorry guys, just a bit off topic, but it's for my TA05.

I was in the market for 64p spur and I was told that the standard ratio calculation found in the manual can't be used to calculate when using 64p gearing.

Can anyone enlighten me on this

Thanks!
Roy

Spur divided by pinion times the variable 2.25 = final gear ratio!
The variable should never change!
I hope that is what you wanted to know!

The internal ratio is always 2.25 to 1 no matter what spur gear you use. Click on the link in my Signature that says gear chart and print one out for your car............

So it's the same calculation then.

Any spur/pinion combo for stock and 19T?

Thanks man.

I think the biggest 64 pitch spur that will fit is 104 teeth!
Other than that, NO PROBLEM!!

comparison between silver, yellow and blue springs:

coil diameter: 1.4mm

blue - 6.3 approx.
silver - 6

moreover, the silver springs are slightly narrower in terms of spring width, averaging 15.8mm compared to 16mm of the yellow and blue. and we all know a narrower spring=less coils=stiffer

disclaimer: this is just my observation!! tamiya may have used a different metal in the kit springs for all i know!
The kit silver spring has the same coil count and same diameter as the Tamiya White spring (not yellow). The only difference is the ground ends on the Tamiya white. The lack of ground ends makes the silver spring a hair stiffer than white. I prefer not to use the silver springs since the non-gound ends tend to get caught up on the lower spring perch slot - as you turn the spring, it moves up/down - which is not ideal. The actual measurements are:

Purple 22.72
Gray 20.91
White Short 17.54
Silver 16.13
Blue Short 15.69
White 15.27
Blue 14.08
Yellow Short 13.99
Yellow 13.33
Red Short 12.35
Red 11.86

The biggest i have tried is a 106 and that was just barely inside the chassis. The 105 is probably the safest bet. Tamiya makes a 105 for the TA05 which at 0.4 module size is slightly smaller than a 106 only.

Remember spring "rate" is load increase over a given distance. so a 10lb spring might equal 1" movement and the load increase is 10lb over that given 1". Simple explanation but you get the idea.

So how all that relates would be that initial tension on the silver might be lighter but as the car rolls the spring ramp would be quicker.
Hey Dan!
All the tamyia springs measure pretty friggin linear. The initial 0-0.2 lb worth of travel is non-linear due to the ground ends and the different coil pitch at the ends. But other than that, all the tamiya springs are completely linear when compressed up to half their original free length. They all follow the general F-Kx equation very well.

It's a rubber/carpet track
