shipping from japan is just as long as ordering from Tower... I usually get my stuff in 4-5 day after order confirmation. I'm in CA.

hey i wanted to ask about the advantages and the disadvantages of the wheel spacers (what do they accually do?). i have just always used the fat 1mm spacer and have never tried anything else. but i was looking at the setups on HPI's webpage and i noticed that the drivers used the different sizes. what do the different ones do? what will i loose/gain by going to a thinner spacer or no spacer?
anyone?
anyone?

I tried it when I got home but by the time I had got the wheels to lift at the same time the shock collars where completely different, more than quite a few turns of the shock collars.
Is this right? Any thoughts? How do you guys (and girls) balance your cars? MIP tweak station?
Thanks

it works like this: if your droop is equal and your car is balanced (tweaked properly) the tires will lift off the ground equally when you pickup the center on either end (front or back).
so if one tire is unequally weighted when you pick up on the opposite center of the car it will then lift off unequally.
so while this method does work using a tweak station is significantly better.
here are the flaws with NOT using a tweak station:
-droop has to be perfect
-you should use setup wheels not rubber tires because its inaccurate as to when rubber tires lift off
-it doesnt take into account all 4 shocks at once. (this is a very long explanation as to why this matters, if you care lmk and i'll send it to you) this is basically the reason why you may end up with shocks on one end of the car WAY out of wack (simply because you have to adjust each end independantly, you cannot use front and rear shock adjustments to fix a front or rear only problem)
-must make sure you lift in center (this applies to tweak station, however centering car on tweak station is prolly easier)
basically its like this: if you cant afford or cant access a tweak station then check ur droop and use this method. otherwise USE A TWEAK STATION!

By the way I didn't realize the 2.0mm chassis was only $40 at Tower! I plan on running my Pro 4 on asphalt, is the difference between the 2.5 and the 2.0 noticeable? If so I may pick it up. Thanks for the assistance.

I will buy a mip tweak station as soon as possible.

Who do you buy Pro 4 parts from in the US? Tower has a good supply but they don't take Amex or PayPal (the 2 my wife don't see). I am looking for HPI and Tobee Craft parts which can be tricky to find in the states.
