Another thing to consider is unless you have a cage these seats are less safe then your OEM ones (especially if used with a harness) since it doesn't allow you body to slide to the side if the roof gets crushed in an accident. Probably not a huge deal for what you plan to do (although if you're going to Porkeys you may be out there to do some "spirited late night driving" as well).

One other note that the guy from Apex Performance noted when a friend and I were looking at seats is that you can't reuse these seats after an accident. Something about deforming or the structure being compromised. Which both me and my friend got a kick out of because the last thing I'd be worried about in an accident would be having to replace the seat. But I guess if you're a serious racer that could be a factor.
