I didn't find any info on that secondary helix & spring.
It may be OK with a stock primary, but i feel some performance will be lost.
3 options:
1. Put aftermarket primary parts in & hope the original "tuner" knew what he was doing. From the looks, i think he did
2. Put stock helix & spring in secondary cuz stock Apex clutching is perfect
3. Run as is & if it works ok with no issues then "se la vie"
Don't forget that the original belt took some abuse so if you think things are OK then change it.
It got smoked more then once.
P.s: Se La Vie means "that's life" or "such is life" although it's actually C'est La Vie or CosI e la Vita in Italian
