Yes, the B44.1 is pretty much ready to go out the box.
This setup will be a damn good place to start for Area 51:

Just use Silver front springs and green rears (the ones that come in the kit
)
Only mods for carpet would be the AE or Rudebits weight for between the cells:

(can't link to the Rudebits version but easy enough to find on the site)
And an extra roll bar for the front that helps on carpet.

The Ghea #2s are a useful tuning aid for the rear

And there should be plenty of us at the Area 51 GP running the B44.1 so feel free to ask questions.
