At our club (Colchester Scalex Club) we run analogue on Carrera track, I've got a Nissan R390 and all I've done to it is a Slot It wood track guide and P6 tyres, Carrera track is very flat, rigid and smooth so tyres are the thing to get right, the only tyres I've found that don't work well on Carrera track is silicones, which seem to be good for around a minute and then drastically go off, but Ortmanns or rubber tyres work well on Carrera.
Are you running with or without magnets, because if you're running with magnets (we don't) the Carrera track gives less magnetic attraction than other brands of track.
