I see a lot of setups with shims, top and bottom of shocks. What does it do and why? |

Since joining Xray I have always used this, but recently we have tested it. You seem to get a little more roll/grip with less shims so its simply going to be a try it and see. I dont think it transforms car but does make a difference. Oj |

The main ones I play with are the ones at the top of the front shocks. Adding shims (up to 4mm max) makes the car more stable, reducing mid-exit steering. Removing them (down to 2mm minimum) adds mid-exit steering. Still need to test the rear shimming to understand it more. |

Definitely agree that adding shims behind the top of the front shock will make the car smoother in big/sweeping corners. This has always worked this way at my home track on the old CRC carpet and it is one of the changes I recently tried at Snowbirds on the new CRC carpet with the same effect. This was a small change I made at Snowbirds to make the car a little easier to drive and more consistent. For rear shimming, I have always felt that more shims under the bottom of the rear shock increases rotation. Though I pretty much always run the kit setting of 2mm behind the bottom but remove the shims from behind the top of the rear shock to achieve the same feeling. I did not get to test this on the new CRC carpet. |

Thanks for all the great replies. It's all good stuff. I generally try to run a very neutral setup, as it makes it easier to drive. At 65 I need easy...lol. But, I'm struggling to understand how the shock angle, in respect to shimming, has so much affect on how the car handles. Thanks Darryl |
