You don't want IF347-138 in the front.
For the fronts you want IF347-128.
Then you want IF346-03 for shock membranes.
With that you can run Losi 40 to 45 front and 35 to 40 rear, depending on temperature.
Or in CST, of which Kyosho shock oil is spot on exactly correct (other brands are not), 550 to 700 front, 450 to 600 rear.
(If very warm you need the thick oil.)

Just because a bunch of people make the same mistake of running the 1.3x8 up front, when they should be running 1.2x8, doesn't make it the right thing to do.

If you're talking about the bushings that go in the hub carries, they don't have dots. Looking at the bushing from the front (the side that faces the front of the car) you have to look carefully to see see if the hole is exactly centered (0 degree bushing) or slightly off center (1 degree bushing). It's easier to see if you slide the hinge pin through it and you view the angle of the hinge pin.

I did some testing with the 1.2x8's a while back. What I noticed is that they get the front of the car turning in faster than the 1.3x8's in the hairpins, but the trade off was that they seemed to push a little after the apex. Just throwing them in on a pros set up might not be ideal, but if you get them to work with the rest of your set up on the right track they probably would work. As the JQ Guide says.. one change might be worse, two changes might be better. I gave up on those pistons mostly because I was too lazy to redevelop my setup around them. I might have a second look another time. A pro driver at our track does use Kyosho 1.2x8 front / 1.3x8 rear, but in a different car.

However, in this case, yogii is looking for some sound advice on how to get his initial setup on his car with proven, time-tested settings that will work well on almost every type of track. Once he establishes that, then it may be a better time to assist him with refinements such as your suggestions above.
I'd also like to add, the reason I came to Kyosho in the first place, was due to watching Sean Gaffney wheel his MP9 back in 2012. His car always looks like it's the best on the track by far, granted he could probably make a Traxxas look good too. That being said, you can definitely have faith in any setup he is endorsing.

I've tried the 1.2x8 pistons in the front, they're ok and can certainly be tuned to produce different handling characteristics on certain tracks that you may prefer over the 1.3x8s. It's not a matter of one being better than the other, it's whatever suits your feel and I'm fine with that. I do think the tuning window with the 1.3x8s is larger than the 1.2x8s, meaning they are less sensitive to oil/temp changes than the 1.2x8s. Which is also what makes the 1.3x8s so good - you can drop an MP9 with Codys 2010 worlds setup on basically any track and provided you choose the right tires you'll be on-pace or at least very close to it.

HH hit the nail on the head. Just a matter of trying to guide a guy who hasn't had the car on the track yet to try the baseline setup that probably all of us tried at one point or another. And thanks for the kind words HH, I've worked hard to get my suspension to be butter.

I've had 2 front shock towers slightly bend on me, including the Hard Front Shock Stay [KYOIF477]
Can anyone tell me if the Fioroni Kyosho MP9 Ergal Front Shock Tower is any better?
Cheers

I had mine bend slightly too, I just straightened it out. Slightly bent isn't going to really affect performance that much, if any..

Yep i have bent it back as best as possible, but just wondering what the Fioroni towers are like.
