If you are on about the bolts that secure the runners to the floor. They are just a T50 torx bolt IIRC

I've seen many posts that say that this is a T50 Torx head, and only one that said it was a Ribe head.

I have recently removed the seat runner retaining bolts from my drivers seat and after rounding off one of the bolts with a T50 Torx (it was very very tight), I bought a Ribe set from ebay for £13.95 link. I then used the 8mm Ribe bit to remove the other 3 bolts without incident. I'm certain my car has 8mm Ribe bolts fitted.

It seems to me that the T50 will work on bolts that are not as tight as those on my car - but I believe the 8mm Ribe is the correct bit to use. I would suggest that if you use a T50 make sure you have very good downward pressure whilst undoing the bolt.

Interesting. I've not looked at mine, but what's generally seen as a Torx socketted bolt may well be something else more suited to high torque applications. The seat bolts are always damned tight and it's not surprising that this may defeat a Torx drive, which are for lower torque use.
I've not come across a Ribe drive before and Wikipedia has no references to it. They are available on eBay and from there I put together this graphic showing the similarity between three hex-splined systems.



The Polydrive looks even closer to the Ribe than the Torx and it makes you wonder if they're the same system. The Polydrive has rounded spline roots whereas the Ribe is seemingly square. Both are for high torque applications.

The upshot is you need to examine the bolt head carefully to determine which drive system it uses. Using a Torx driver in a Polydrive bolt will almost certainly damage something.
