Anyone using the Timbren bump stop (suspension enhancement system)?

[snorkerelli]

I just purchased the Timbren bump stops. Wondering if anyone else is using them and what the recommended number of spacers to use on installation? It comes with two spacers but would like to know what works well before having to go the trial and error route. I can’t find any more info specifically for the LC 250 online. Thanks for any help.
