Raz, did you ever test your shock package with a shorty?

BIGSKI15 02-13-2013 06:00 PM

I go mainly to two tracks, one with high traction where slicks are the only tire used and another that is very loose with little water. My high traction set up is pretty good but I'm trying to figure out what I need to do to the car for loose conditions. I have the AE's recommended big bore set up, black front spring 30wt, 1.6 piston and the rear has a white spring, 27.5wt, 1.6 piston. The only thing I change for the loose track is a green rear sping which helps. The rest of my set up is below.
2 washers under the front ball stud
1 washer under rear ball stud
Ballast weight
5 grams in rear and front triangles
Ride height 24mm

When I go from track to track, I normally only have to change tires and ball stud washers. Maybe springs is the difference is radical. Soften the springs and get the right tires, should be 95% of what you need. Then minor changes with washers. Tires might need softer foams also.

Would i remove or add washers for the loose track? I'm thinking I would remove washers to make the link shorter, correct?

I would think yes. Lowering link should raise the roll center

You could also shorten the wheelbase and lengthen the rear camber link by moving the hub ball studs out

Depends on what your starting point is, the tire/foam combo, and available traction.

If you remove washers, you'll stop the chassis from rolling as much, but that could result in over-rotation mid-exit corner.

If you add washers, it could be the opposite. The only real way to find out is to try it.

Hey dummy, the 0mm offset cups are for buggys.

b4.2 manual states 5mm offset for the buggy.

but with a stiffer spring you could use the 0mm offset cups, so i believe they are for the b44.2. 5mm for b4.2. 9mm for t4.2/sc10.

i have yet to put my car on the track, but im starting exactly where cav was with the battery... and tebo in his rb6. 2 silver in the farthest slots. leaving the battery at about 250g (close to a wolfpack)

as i said before i dont like how much "blow-by" ae pistons seem to have, but cannot find a true 2x 1.7 12mm piston from any company, short of buying blanks and making my own that is...

looking at losi 4x57 or 4x56 tho... or maybe avid 2+2 1.6/1.1 pistons...

anyone running anything non-ae in the big bores they have found they like in the buggy?

Do you know what the black grease and diff lube is? Not that we need it as we always get plenty of black grease and diff lube with kits and full diff kits, but still.

Molybdenum and clear silicone

I had kyosho 5 hole pistons in my ae shocks for awhile and they were by far the smoothest they've ever been. But even with 40/35 oil I needed a bit more pack for my local track conditions. Worth a try though

Wonder what size holes the other pistons are.
