Need a resistor upgrade myself & came across this thread whilst looking for info.
Yes it does seem a good idea to source the "kit" from Jules but I have a garage full of thing like nuts, bolts, crimp fitting etc so only need a resistor.
I know it needs to be 100w but what other specifications does it need to meet and would this do the job equally well
