Glad you feel that you can now go a little deeper into the topic and start testing different configurations. Remember that the clamp shim is the quickest and easiest to do.

@@CatalystReactionSBW i'll read up on clamp shim :)

Compression and rebound adjusters are dynamic by modulating flow via separate circuits so look at them as independent systems. Stock valving is generally set based on the spring installed (progressive), so with linear springs, rebound and compression are much more easily set. If you go up or down in spring rate, assess where you are in the total range available and that will guide you to the nature of a possible revalve.

Depends on your ability and use. If this is for the road, springs and oil for the front can make a profound different as and just a rear shock spring. Start there. Same would apply for a Novice track rider. At intermediate track you would need Andreanni etc for the fornt and a shock.

The doughnut stops the compression and rebound piston colliding with each other. Your call on retention as it will give you an extra 1/8th of an inch of travel.

@@CatalystReactionSBW thank you for your response… I suppose it’s not worth the risk if it’s only 1/8 of an inch .. doesn’t seem like much of a gain ..

The doughnut on the rod stops that happening and creates a gap between pistons. If that or other device on the rebound rod is removed, you cannot stop the collision happening so you add preload and compression to reduce travel used for safety to attempt to avoid parts hitting each other.

If there is a doughnut on the rebound rod - that has to be removed and you need a special vice holding tool from Race Tech to get hold the rod.

Thanks Dave!
