Can anyone recommend a good quality sliding seat rail for aftermarket seats?

I have a Sparco Evo seat and I've been using the Science of Speed sliding seat rail for the past few track seasons. It broke recently and I would like to get something more durable and of course safer. Does anyone have a recommendation or do I need to mount the seat to the chassis and leave is stationary?

Hi Ryan,

I started this post recently asking the same thing, but have not had much response.

I am going through the same issue, my SOS ones have not broken, but I feel they will with the abuse they are getting they move around a lot at pace. There is nothing the matter with the quality of them and their new versions look better but for heavy track use I think fixed would be best.
Those Planted ones look ok but you still have to get some side mounts to fix the seat to, the NSX 'R' model has the passenger side fixed so would be good to get a look at how Honda did it and just do that which means finding someone who can get something fabricated
