    XR1 Steel Block Help

    Hi,We run a 2020 XR1 with a wet sump Wissota engine (415lbs) and fire system and looking for some help with smash starting points.We are limited with rear percentage with the suggested starting fuel load and can’t get near 52% without adding 50 plus pounds there. The car lacks forward drive compared to the other combinations with over 54% rear weight but is loose in and through the center. We are close on 3” RF number and have been taking out LR static as such. Any advice is very appreciated
