i was told that they give a little bit of power but limit the use of your accesories i do not know from experince and would like to i was also told i should not mix light flywheel and pulley kit, can any one tell me why besides the possibleity of a really low idle.

ive herd it puts a little more stress on your motor....not sure though but thats what ive been told.... and if you do the undrive pulely your light will dim, but a lot of people with pulleys said they could feel the differnce...

I have the uuc ones, i did them at the same time as the fan delete and cooling sys rehaul
so I definitly felt the increase in power. Easy to install, well made and the belts they provide are top notch.
The Eurosport ones are the same deal but just way more money. I certainly recommend the UUC ones

i wanted the eurosport ones cause of the look and the lightweightness but i went with the UUC ones and i didn't really feel a difference in power but i did notice faster revs. but i did the fan delete at the same time..

I was looking into buying the UUC ones but there have been on back order for a few months (for the 328)... no clue why...

combining UD pullies and a light flywheel can result in a broken crankshaft if you spend alot of time in the upper end of the rev range. The light flywheel by itself has been known to cause annoying rattles in the trans at idle as well.

UD pullies in cars with big sound systems aren't a good idea either if you spend alot of time stuck in traffic. Extra drain on battery and charging system. Other negatives include AC doesn't work as well, water temp goes up.

They do work, but there are trade-offs to consider... for regular driving they are fine, It's just when you get stuck in traffic for 2 hours on a 100 degree day that you may start reconsidering your choice.
