@ Fil,
the comp eliminator class is the not the easiest to explain - it would be much
more useful if you can post some random data of your car like weight, engine
size and so on. (i assume it`s a nitrous car?)
The svedish rulebook / index is now listing PM "style" cars for comp eliminator - either you can go that way or maybe choose AN/A if that is going to suit your car (needs).

So we are waiting for your info.

best regards

Björn
