Im looking more toward Sparco's for the 911 and wanted to hear from any other 6speed members who use them and what is needed to complete the project (sliders, mounting brackets, etc).

 

SPARCO EVO 2 PLUS Seats, 6 Point SPARCO HARNESSES, Full Roll Cage.

 

I know you asked about Sparcos but figured I'd share...

I have 2 practically new OMP ARS seats w/brackets for sale that are similar in size to the Sparco Evos. I had them in my car for only a few weeks before I had to remove them to put the interior back to stock.

I LOVE these seats but family comes first. They were super comfortable and fit the car very well (with only some slight rubbing on the center console). They bolted right up to the OEM manual sliders with Brey Krause 9071/2 brackets.

I have the seats, bk brackets, and oem sub bar all for sale (all practically new). PM me if you are interested.

Here are some pics of them in the car.

 

A number of Cayman users have installed the Evos with good feedback.
