It definitely makes you think about whether a risky move is worth it coming out of turn 4. If you wreck, you lose most of a lap on the restart. I was skeptical initially about this method, but after 6 years of doing it, we like it. It isn't for everyone. Another thing we like about it is that if we only have 6 racers for a race, no one has to sit out to marshal. Everyone races.
These super mods are a lot of fun. We are finding that even on our small flat track, adjusting the wings has an effect on handling.
