No, but I have the March aluminum UD 3 pulley set. Well worth a little more. It is the Power and Amp set for 88-91.

If someone installed these on their car, would they have problems if it were a daily driven car?

The March set actually speeds up the alternator. If you slow it down with underdrive pulleys you may get a red light flickering on the dash at idle due to a low charging rate.

Well yeah you'll have to use premium gas. I've had the March set on mine since not long after I bought it. They work well.

Aluminum is different from steel.

Thats horse****, they say that about certain mufflers (muffler elims) and exhaust systems that don't have catalytic converters in them.
