The best parson to answer would be Tony but I tell you how I feel about it. If you drive on billiard table smooth tracks then stick with the standard pistons. If your track if rough or you find the car to twitchy then try drilling to 1.2 mm. Use the same number of holes in each shock that you used previously, just increase the oil thickness by 10w all roundinitialy to compensate. To drill the holes you can get an RPM piston drill set. Not expensive but hard to find. It has a good selection of hand held drill bits specificaly designed for drilling shock pistons. |

The piston holes are 1mm. You can drill them to 1.2mm if you want. This makes the shocks a bit smoother and allows you to run thicker oil. I think the latter is the main benefit as the shocks will stay more consistent. Nowadays I run 1mm holes almost exclusively because the difference is to minor in my opinion. BTW, you can drill the keyed pistons up to 1.2mm too IF you use a hand drill.... |

thanks everyone,tony so it could be better if i drill only the rear schok's pistons? it should allow me to run the same oil at rear and in front using larger holes in the rear.........what you think thanks again |

I have never tried it myself but it seems worth it to try. Easiest would be if you have two sets of dampers. You can then build one set with 1mm holes and the other with 1.2mm holes and 5-10w heavier oil. This would allow you to try 1mm all round, 1mm front 1.2mm rear, 1.2mm front 1mm rear and 1.2mm all round without rebuilding... |

yes this could be great but i'm not a bank  just joking tony
but is not good (in theory) to have larger rear pistons? i think the chance are 2 basicly: - 1mm piston all around with a tickher oil in front (or 1-2 holes closed much more than rear) -1mm front pistons holes and 1,2mm rear pistons (three holes all round) same oil front and rear what you think? |
