Pneumatic Valve Spring

Hi Devs team,
I was thinking about some hi-end equipment that you can add to the game for racing car scenario or just for sandbox insanity
What do you think of Pneumatic Valve Springs ?
it allow a lot higher peak rpm, but on the other hand it is a very exclusive component (expensive)
and the fact it is a small piece save you a headache to artwork it !
