I have just purchased a cobra evolution seat and alloy side mounts after having a cramped thigh from bracing myself my last track day. I am now shopping for a base with slider. I have had the sparco base and slider and was not impressed. The nagisa auto ones look nice and low which is great in these cars. But let me know which ones you guys are using, how much they cost, and pro's and cons. Also for tech fia approved or whatever they need to be.

 

I have the Nagisa rails on my Ultra Shield seat. Works great, and yes it sits low.
