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...
