I've know JG for quite some time! Before Dermot C's Ford days, I helped to build/run the cars through to the 5 GB1 titles
JG's GB1 title yesterday is his 6th, something he has been chasing since 2015
Car wise; Derek's an OMSE built WRX car. JG's is a 2004 build car running M-Sport WRC Escort transmission etc
I hope the Lydden Winter Series works? Entry fee of £145 and reg's compatible with both BTRDA and BRX car's should work "B" permitting
Something you may have missed is LHMC will be running the 2020 "MSA" championship
Hopefully it will be promoted . . .
