@Smith423 I don’t own a speedster YET!!! But i’ve Done some extensive research on this subject in particular. A/C takes about 10 horses off your power... 1600 about 90 hp... so 80 with A/C on. Depending on your location I hear some guys who have actually removed the A/C because with a car meant for top down driving... They never needed it. I drove a speedster in Hawaii and wouldn’t really see the need for A/C in such a climate... but LA, Or Arizona... I would want one especially if it’s a daily driver. Yes, the sun could be blocked by the top but with the top up it’s like an oven with that engine heating up the interior.
Vintage Air seems to be the go to for speedster A/C systems.
good luck! Hope it helps!
