My brother and I run 4 hole pistons. We've tried the two holes, and countless other setups. But came back to 1.3 x4 holes.

It seems like everyone is running the 4 holes. My issue with this is that we'd have to get a 1.3 drill bit and drill our own using the blanks that was provided...

Having said that, why can't we just use the 1.3 x 6 holes and use a thicker oil? Won't that make up the difference? The question is, what flavor of thicker oil? If we are using 40/30 wt with the 4 hole, do we use 50/40 wt with the 6 hole? Or even 60/50 wt front/rear?

Kudos to Durango for dumping the chassis and going to a +8mm plastic chassis.

In a word- pack. The 6 hole pistons simply do not offer enough pack on tracks that have anything more than small jumps, unless you perfectly downside them every lap. Cornering with 6 hole pistons can be dialed in very well, but chassis slapping and getting the car upset is what made guys go to 4 holes. That said, we're trying 2 holes in the buggy this weekend as they have been excellent in our ST and SC trucks.

I'm not sure if you read my post correctly. Using THICKER oil with the 6 hole piston, wouldn't that give you all the pack you need?

Im using the 6 hole with 60/50 and still get slap off small jumps

Plugging the holes is easy enough. I use JB Weld. Some glue them. Some melt the hole shut.

The number/size of the holes is what relates to pack, not the oil weight. So no, it won't. To achieve enough damping to simulate the needed pack, your oil weight would be so high that handling would suffer- unless, like I stated before, your track has very small jumps or you are able to precisely downside every lap so as to not slap and kick the chassis.

Read this for starters: http://users.telenet.be/elvo/. Particularly the suspension section that deals with damping.

And I highly suggest this: http://www.amainhobbies.com/product_...ston-Drill-Set

That tells me I need to try 70/60

That's a darn great point!!

Yup. Gary's (GMK) Drill bit set is a must for your Shock needs.

didnt find that site yet im always looking to learn more ,, doesnt the way the oil flows throught the holes affect all of this especially the number of holes not just the size and if the hole isnt perfectly circle

i use 4 hole 55s all the way around and it works awsome no bounce off the jumps.

I understand what u mean now. i will run 4 hole pistons and then go from there. And thanks for that link very helpful

Want to buy 210 but im being told not too. Doing sc now never owned a buggy the 210 being highly tunable i could mess it up. Indoor dirt clay track is where ill be running. 210 looks awesome will get one a some point but should i start with a b4.1 .. opinions. & thoughts greatly appreciated thanks.

M3Armand

If you're a newbie, you're probably better off with the B4.1. There's probably too many points of failure in assembly and maintenance for you.
