I subscribe to the belief that the lightweight pulley has no ill effects on the engine. I did the Perrin pulley and Airaid intake at the same time and liked the result. I was running the stock exhaust at the time. It is an easy mod to do and I have no regrets.

...regarding the stoplight thing - BRZ (FR-S) is not my vehicle of choice for that type of activity! But, I totally understand where you are coming from!!!!
Haha. True that... Not my thing either, but every now and then it's fun to have a little 'under the radar fun'. Nothing to crazy...
I guess since there are no complains, I may go for it.
And yes... I was aware it doesn't add HP but rather helps with gear transition and take off. So... I may require tips once I get it!
