I don't understand why people give this kind of comments. If you can't see the effect with your own eyes, it doesn't mean the device(stabilizer) is doing fck all. They actually reduce electrical noise and distortions, and it will increase the lifespan of the battery and the charging system(alternator). These stabilizers won't help with high current dips(headlights, ac, windows etc.) as their capacity is quite small, normally 10000 - 20000µF(microfarads). If you want to reduce high current dips, you will need a big audio condencer with capacity of 1-5F(farads). Is there Starlet specific grounding kit available nowadays? groundingkits.co.uk or something like that was selling them back in the day..
