Does anyone actually have the Stillen UD Pulley? I don't have any aftermarket sound systems and I am running low on things I want to do with the car. I have researched and heard that this does add some HP and makes the car lighter. That's all fine and good, but will it ruin anything in the long run..or rather does it have any negatives? Do the Positives outweigh the Negatives or vice versa.

Additionally, are there any other new mods coming out soon?

Thanks guys!

There are a few members with this installed and seem happy with it.
If I had a car for track use I may invest in something like this. For Myself I really don't see the return on investment for a daily driver vehicle.
Just my two cents.

 

Thank you..that's what I wanted to know. Yes, the road is my track ..Soon it is time to get a second car. I am almost done modding this car..May get the new 370z, 8th gen, or be a d-bag an get a 335 bmw
