Hi Todd, As Jack has shown you from our tech form, four point harnesses are not permitted under any circumstance. We derive our rules from PCA National which provides our insurance for these events. If attachment points are your concern using a five point harness, you could use a six point which may be easier to adapt to your car. Please send me a PM if you need further information or have particular questions you need answered on this subject.
