Starting average: 8.00

Starting average: 7.25
Panthers beat off fierce competition from Premier League rivals to snap up one of the hottest properties in the sport. Lambert, who also races for King’s Lynn in the Elite League, competes at this level for the first time in 2015.
Starting average: 6.30
A city-born and county-based racer making up for lost time after being a late starter in the sport. Enjoyed a terrific debut season for Panthers until it was cut short by injury and sure to challenge for a heat-leader berth this season. Also rides for Wolverhampton in the Elite League after being the star reserve at that level for Eastbourne in 2014.
Starting average: 4.78
A fine talent whose career has been badly affected by a catalogue of serious injuries. His curse continued when being hurt in a crash in the opening race of the season last Sunday, but he will return to the Panthers team once fit. A Premier League winner with Rye House back in 2007.
Starting average: 3.73
A former Great Britain Under 21 international who from Gosberton Risegate, near Spalding. Three-time winner of the National League Pairs who also has extensive Premier League experience and could be a shrewd signing.
Starting average: 3.40
The reigning British Under 19 champion was a surprise addition to the Panthers team after initially signing for Premier League rivals Somerset only for work commitments to prevent him from taking up the Rebels post. Returns for a second successive season after riding for Panthers in the early part of 2014.
