Shock Pistons

[N7ELA]

On the TRF Racing website under the 201 and 511 'to complete the kit' section there are 3 different types of shock pistons.

1.3, 1.4 and blank.

Every setup i have seen have always used 1.3 and 1.4 mm pistons.

Are the blank ones only used to drill custom size holes in place of the other 2 or is there some other obscure reason why people use / buy them?

After all they are listed in the section to complete the kit and it kind of suggests you need them...

Just as an option, ready to be drilled 2 hole, 3 hole whatever might suit the track.

Have to agree Mike Pimlott, but you don´t need them to complete the kit, they should be an option not a necessary part to complete the kit. The 511 includes thw "W" parts which include more than one option. They are molded, not machined as the option ones. They are a bit more precise i guess but at the same time i doubt that you will notice a difference as these dampers are smooth either way.

Thanks guys,

So do people use 3 and 4 hole pistons then as opposed to the 2 hole ones?

Why?

And if so what size?

Is there some fancy Pie R squared calculation as 2 x 1.4 mm holes will give more restriction than 4 x 0.7 mm holes. wont they....?

I've been looking at the 1.3 and 1.4 ghea pistons, but not sure if they are worth it on the 511.

I currently use 2x1.3mm front and 2x1.4mm rear.

I drilled blank ones 3 hole 1.3 and 1.4mm but i didnt like it. I think the tamiya springs are very soft anyway and 3 hole piston didnt work for me.

Might try it again on real bumpy tracks but with blue rear springs and black fronts

So if i had 2 x 1.3 mm holes with 25 weight oil

and 4 1.3 mm holes with 50 weight oil,

what would be the difference?

Alot I bet but do people really use the blank pistons for extra holes?

Or do they stick to 2 holes and just drill them to 1.1mm or 1.5mm etc????

i use the 1.3 2 hole with blue springs and 30/35w oils works fine for me

Im not sure about this, but have a read through the suspension part of this:

I drilled them to 3 hole because i wanted less pack on a bumpy track, this made the shock react quicker. It worked on the bumpy section but rolled too much in corners, wasnt quicker!

An interesting read,

Has anybody else used more than 2 holes and did they drill smaller, or has anyone just tried using 2 holes and drilling smaller or bigger ?????????????????????????????????????????????????? ???????????

Out of interest, what pistons fit the Tamiya dampers? Cheers.
