Today I bit the bullet and picked up a pair of Porsche GT3 "alien" seats to use for HPDE track days. I am going to install them tomorrow without any harnesses and use my factory seatbelts for 1 HPDE at the end of the month, but over the winter I will buy harnesses and a HANS device. The shop I use for safety equipment is recommending a custom harness bar they offer rather than attaching the shoulder harnesses to the horizontal section of the factory roll bar. I think all the street driven Boxsters I have seen at the track have the shoulder harnesses attached to the factory roll bar. I am between 6-2 and 6-3 on my best days. I think I understand that the harness bar would sit lower and therefore make the shoulder harnesses more secure. If you have 6 point harnesses in your street Boxster, are you using your factory roll bar or a harness bar for your shoulder harnesses?
