I am quite sure that is 3 degrees anti squat. Stock (no spacers) is 2 degrees. Adding 0.5mm spacer on either end creates 1 degree of squat change.

Default stock diff vs mip diff

Ok, so I've been running the mip pucks in my stock rb6 and I'm chewing through the orange pucks . I'm thinking about going back to the stock diff and I'm curious if the weight savings is worth the money to keep replacing orange pucks. Also, is there any way to make the orange pucks last a little longer ?

Default pills

I'm sure this is up here already but can't find the info. I'm trying to get to 2.5 to 3 of toe in. Can someone please tell me what letters of pills to use, or a chart. Thanks

A common mistake on pucks is greasing them. I run them dry and they last me a really long time. Another question though is what are your track conditions? Loose dirt canchew them up pretty good too.

Mine last a long time too. I don't grease them because it attracts dirt. Oh also, because I'm lazy....
