The tuning blocks and lowroll center blocks definitely look like speedtech hopups, the caster blocks could just be the red dynamite blocks with the anodizing removed and then polished to look like the others.
You're gonna like the threaded shocks, get the red collars too!

I find it odd that somebody took the time to copy Losi's packaging for those parts. The mounting stuff does look just like Speedtech's stuff, although if they took time to remove anodizing, they could also be the Trinity Matt Francis stuff.

as for a setup, the losi page has some good carpet setups for foams.

Hi everyone ...
What is the different between blue, purple and green springs?
How will the shock oil effect handling (40wt, 60wt) ?

Having different weights at the front and back is an option that many racers use to counteract a car's tendency to oversteer (spin out) or understeer (plow) because it allows the car's weight transfer (the key to handling) to shift more evenly and equally.
Again, it's only part of the puzzle; there's no magic oil weight combo for the XXXs (or any other car) as the selection is wholly dependent on the rest of the car's setup (springs, linkage points, kickup, tires,) as well as differences in race surface and the driver's driving style.
Hope this helps!

ok ...
so let us assume that I am racing on an asphalt track outdoors with ...
BLUE springs front/rear
and
60wt shock oil front/rear
Now if I am having a problem of UNDERSTEER, what will be the possible solution ?

Well, there's a couple things you could try.
The car is probably understeering because the front is providing more resistance to side forces than the rear is; meaning, to oversimplify, the front is too stiff (or the rear is too soft.)
Therefore, if the car is understeering/plowing, you need to "soften" the front or "stiffen" the rear. This could mean:[list=a][*]heavier weight oil in rear[*]lighter oil in the front[*]stiffer springs in rear (or more pre-load)[*]softer springs in front (or less pre-load)[*]"lay down" the shocks in the rear (making them more progressive/softer)[*]"stand up" the shocks in the front[/list=a]
Do only one of these things at a time - if you soften the rear and stiffen the front at the same time, you may overcompensate.
All of this assumes that your car is balanced well, both front to rear and side to side. If the car understeers going right but doesn't going left (or vice-versa), you probably should focus on balancing the car first.
Also - do your tires suck? That's where my biggest problem was. When I finally found the right combo (low-flex wheels with Losi Yellow Low Profile slicks) my car started to really hook up.

Do you really mean that if a car is UNDERSTEERING you should harden the front or soften the rear ?
I thought it was the opposite
If you soften the front, you should have more grip on the front, no?

Have a look at this site ...
http://teamrcv.com/article.php?sid=134
NOT ENOUGH STEERING
CURE :
Softer front springs
Reduce caster angle
Move wing forward/shorten spoiler
It practically says ... that if you have understeer, you need to soften front springs, thus increasing front traction and steering ...
I am confused (It seems to the contractrary what "sixandeightstri" said above ...
Any comments ...

Sorry, brain fart.
This is so much harder to explain in text over the internet - if you were in front of me, I could just show you...
