Hi matey,
From stock kit in mid motor for Astro i would get:
5 deg Castor blocks,
Gurnell RC Tapered Pistons (see 'Nick's thread in Losi section)
Black/Blue/Green front springs
Pink Rear springs
I always run 80g under LiPo weight and if it gets damp/wet then the 50G TLR rear weight kit, also if track is very bumpy i've found the rear weight to settle the car too.
Would recommend Titanium turnbuckles, the kit ones do bend and can snap with hard knocks, but will be fine to get you started... they do take some punishment!
I run and love the gear diff, found it a vast improvement, on Astro would start at 5K oil... if not then definitely upgrade balls in kit diff to ceramics as kit ones don't last long before needing replacing anyways!
The Titanium threaded kingpins made the steering action smoother and you can adjust the slop/play with the nuts
Titanium threaded outer rear hingepins do the same, you can adjust the play in rear hub which is a good thing.
i run +1.5mm width rear hexes as it makes the car more stable in a straight line and gets rid of some of the turn in, the 22 has lots of steering compared to other 2WD's which will you'll notice on first run but soon get used to, can be dialled out if needed.
would recommend fitting longer threaded ballstuds for camber links all round as the kit shorter threaded ones can pull out and damage the mounting holes on mouldings as they do.
There is the Cream inner hinge pin bracket/weight which seems popular, a lot of people prefer HRC kit, i have one but prefer the stock 4 deg LRC mount.
hope this helps,
Mark
