Very happy to get down to 1:13.89 after not doing a track day in 2 years. The bug has bitten though and will definitely be back for more!
BTW anyone know if brown Davis roll bar and sparco sprint seat on stock rails need to be engineered? Got defected on the way down to Goulburn

Mate, just been looking through some RTA or whatever they are called and found this so called technical area contact details.

This is all I have found.
Seats
Owners should ensure that the seat and its anchorages comply with any applicable ADR requirements (possibly by certification from the seat manufacturer or by an engineering signatory) and the appropriate seat belts are fitted to all seating positions.
Vehicle Standards Bulletin No. 5 issued by DOTARS covers requirements for the manufacture of additional seats.
However that standard bulletin only talks about additional seats.
So maybe contact Sparco to see what they say, as I'm sure they would want to defend their product.
I am pretty sure if you use standard rails, that keeps you compliant with ADR's there, same for the seat belt. Just get Sparco to confirm that the Sprint V is ADR compliant.
I think you will be out of luck though as I am sure they are FIA approved but not ADR approved which is a bit of a joke considering some of the crap seats out there that are ADR approved. However the older sprint was ADR approved and V is pretty much the same which leaves question marks.
http://www.mx5cartalk.com/forum/viewtop ... 28&t=35664From my understanding you need an engineering cert, regardless whether a seat is ADR approved or not, so any seat change is deflectable without a certificate anyway.
As for the roll bar, I can't find anything other than things on forums that you do need a certificate for a roll bar, but not a style bar.
What defines roll and style however is debatable.
Does MX-5 Mania do Eng Certs for Bars anyone?
Personally I would just remove the Seat and put the standard one back, same for the Bar, and put them back in after the inspection.
