wheel??? what year car? alll my mk2 style recaros have the plastic thinggies that clip on to the leg.. and they slide in the track.
If you still want to buy one of the plastic sliders I've seen them in the Parts Place catalog.
just did 800 miles in my burnt toast which has recaros.. went to philly yesterday to meet up with crazyandy for a 02a conversion... and escher (sp??) aka mk1madness orginizer... for a old abt body kit.. the road may suck.. and i may have pintched a ball or 2 with the stupid roads.. but they are better then other seats..
