I was at kiddy a few weeks ago. 10k/5k made car a bit loose on the back end and at times not enough steering on a few sandy corners. If I had the time I would have gone 7k/3kor2k. Loosen your slipper for this track even if its dry. In the wet it's a must. Also might try going up a tooth on the pinion to smooth out bottom end a bit. Astro is quite worn in areas and its s track that I call "slow is fast".
