I use Kyosho springs, and have been advised by those whom are very familiar with the brand at my local track to do so. That's not to say that I might not notice a difference if I used Losi or AE, but I figured I'd run brand specific.

The cheapest place I have found them is at www.losipartshouse.com

Yes I heard that the losi low freq springs work pretty well. I just already had a bunch of the tuning xgears so never bothered. I tend to replace them when I can no longer tell the colors haha. So next batch I will get some losis.

Ok.. so I'm switching my rear motor over to mid motor. I'm a little confused with the shims that go below and on top of the rear,rear suspension holder. There is supposed to be one below the suspension holder and one above. So my question is on the setup sheets which one are they referring to??? And what is the point of the shim thats above the suspension holder?? It seems like it just raises the shock tower.

You want to keep the same distance between the chassis and the tower,so if it calls for the .5 put that below the suspension mount and the 1.0 above and vice versa.
At least that's my understanding.

These hub carriers feature 0 of outboard rear toe in, and bearing inserts that allow you to use either a 5x13/5x11mm axle bearing configuration, or a 5x10/5x10 bearing configuration. Additionally, the use of bearing inserts helps to improve drive train efficiency and extend the life of the hubs.

From what I can remember, I would run the 5x10 inside and the 5x13 on the outside. I know that isn't a configuration I listed but the kit is 5x10 so you will have to get some 5x13's for the outside. I can't see myself buy a 5x11.

Pete you always want the total amount of shims equal 1mm. So if it calls for .5 then u put .5 under holder and the other .5 u under bulkhead. If it Calls for 1mm the 1mm under holder and 0 under bulkhead

The pistons come with a tuning guide that includes oil and track condition recommendations. Rule of thumb, use the same oils as:

1.6+1.1 is close to 2x1.7, use 30-32.5 wt in rear

1.5+1.1 is close to 2x1.6, use 27.5-30wt in rear; 30-32.5 in front

1.4+1.1 is close to 2 x 1.5, use in front with 32.5wt-35wt

The 4 hole pistons have less low speed damping= more traction and grip on small bumps, but they pack up on big jumps to prevent the car from bottoming.
