Bit off topic, but....
Pete will correct me if incorrect, but the term “Gp 1.5” was adopted for cars running in the British championship after the regulations were relaxed a bit to allow manufacturers to modify beyond Gp1. Other countries adopted their own improvements for domestic championships, calling the category Gp1a or whatever they thought of....
To be absolutely correct, a Gp1.5 car now should be running exactly the same spec as it would have done in period, but there are organisers that simply use the term to class cars that are not running to correct Gp1 spec. For instance an RS2000 not running the correct pancake air cleaner, tubular exhaust, roller top strut mounts, small diameter front springs, etc etc......
