Hi,

I have one that's a bit of a work in progress so far, but is pretty good as a starting point hopefully...

I'm still playing with it, and have moved the rear camber link in to the middle hole since, and plan to raise it a little now to hopefully give a more progressive turn in. But that was for medium grip astro...quite sandy and dusty. For high grip the outer camber link could still be a good choice I would think...and lifted a little if it's really high grip at your track.

You might also go up a touch on oil weight all round...for the same reason.

Worked pretty well at WORM though...got a top 3 finish in the A final on it's first outing with this setup.

thanks for that
will proberbly got up oil in front as i like less steering.
and maybe to 27.5 rear to cope with the very high grip.

Michal Bok's astro setup

Tryed the car today in very dry conditions on High grip astro.
Straight outta the box. With 450cst front 350 cst rear.
Felt very very good. No grip roll, plenty of turn. Alot more forgiving on jumps and bumps than all my previous cars.
Car was a little nose down first on jumps, any thoughts on sorting this?

Good to hear!

How close to the setup I posted did you end up?

Typical things to look at for nose down on jumps...

Too much front weight balance.
Front ride height to low compared to rear
Springs/damping...front too soft or rear too hard.
Antisquat.

All of which could have detrimental effects elsewhere!

That setup of mine I've found to be good on the jumps so far, so maybe just a tweak/check of ride heights could help for starters?

I ran the car at WORM this Sunday just gone...it was flippin awesome to drive!

Only changes made since I posted that previous setup...AE Red front springs (which are slightly stiffer than the yellows, and a lot stiffer than the kit springs...so also help keep the nose up!), and I'm currently on the middle hole on the rear inner camber link, with about 2.5mm/3mm spacer under it...adjusting that height to suit traction levels on track, left it high due to nice dry pretty grippy (but still a little sandy) conditions this time out.

I also ran Ballistic Buggy Whites on the rear for the first time, and they were fantastic on our track! Loads of drive, but no edgy grip roll...awesome balance on the car!
