Default Lack of steering

I seem to be struggling with my steering on my mm,
The back end of the buggy seems well planted but when i turn in i have loads of under steer.
My setup is as per build except green ae springs, 450 oil. And rdrp shock seals.

hows steering setup,

have you got pivot on the shortest hole, then trim arm so that you space servo forward as far as possible, get servo linkage as straight as possible

I run the orion servo, and didnt actually need to trim off the back part of the linkage, guess its different case shape etc

certain carpet tracks my FM I had to run shortest possible wheelbase and then lighter diff oil to get it to turn

but on astro it turns up its own bum

Some things that I have done that made the car generate more steering on slippy floor, especially to combat on power push:

Run front shocks on the inner hole on the wishbone. This tends to be the go to position on most surfaces with the FM.

Shorten the rear link on the hub end, this made the biggest difference to me in freeing the car up.

If the short rear link doesn't give you enough try shortening the front link too at the hub end as this will theoretically make the car turn harder. It's how I like the car but a lot of the other team drivers prefer long. Give it a try.

On rear links run the outer ballstud higher than the inner. 2mm outer and 0-1mm inner helped the car rotate through the corner better.

Finally, on the front carbon steering plates on the front Hubs make sure you are running the outermost hole so the steering link is as long as it possibly can be. This is very important along with shimming the servo forward as far as possible to get the servo drag link as parallel (no angle) as possible. Shim the servo forward (usually 3-4mm so will need longer screws)until the servo horn almost catches the steering post. This is how everyone is running their MM and FM's

Done everything suggested in your post Chris and its transformed the buggy- its turning in alot better now.
Ive noticed in some of the setup sheets from some of the team drivers that they are running spacers inside the shocks under the pistons- what effect does it have on the buggy?

it reduces the droop, but then we have been unscrewing the shock bottoms to get the droop back. this makes it easier to adjust the droop without having to dismantle the shocks.
