AST questions

[Mb21]

Doing some homework so hoping to get some smaller questions answered.
Car is a full track car running slicks or Yokohama AO50. Currently has Spax RSX suspension for those playing at home.


1) AST have a slotted mounting hole in the front strut. How much neg camber can you typically get (15” wheels) with this maxed out?
2) AST adjustable strut tops: how much additional neg camber (struts maxed out) do these add or if used for max caster how much extra caster can you typically add?



End game I’m hoping is I can get enough neg camber (2.5 per side) using the struts and then a good amount of caster.
A mate used to say caster makes you faster 😂

I run AST on the front although with Laguna hubs and some other mods so I can't tell you the difference to caster on there own.

I'm pretty confident you would have enough adjustment to go max caster and still exceed your desired camber.
I really don't get why people fit these mounts and then don't make use of the added caster.

Thanks, I was hoping my thoughts all work out but keen to hear real world numbers 👍🏻

If you can get -3 with BC coilovers, then you definitely will get your -2.5 with AST's.

I never measured the maximum camber angle available, but I can tell you on front I run 2.5° of camber and I use the top mounts to get as much caster as I can.
The slots would let me go way over so I guess 3° wont be a problem to reach

I was able to get around 4.4deg castor with the mounts

My AST’s are at 3 degrees neg camber just with the slots.
