I'm sure you can get the car to work well enough with AE Pistons, ask Lee what he runs in his B44..... i know it'll be Associated Pistons but not sure which - His car was dialled round there last time.
Other thing to consider is that this track has literally no bumps, so shock set-up is not as important as a track such as Kiddy. It's all Tarmac underneath the Astro so there's nothing that will catch you out
