pretty certain no one has ever even thought of lowering a punto!
depends what you mean by benefit? potentially you could increase your cars handling and looks, however also you could ruin the handling/ride if inappropiate springs/dampers are used.
search pretty much any website of lowering springs etc will turn up several kits for puntos or seach ebay.
not entirely sure why this is in the bodyshop section, a mod will be along to move it to punto section soon enough though.
How have you never seen one lowered? Nearly all the people i know with one has lowered it at least 30mm. Maybe you can't tell because it's not scraping the ground .
I lowered mine just 35mm. looks better and handles better but ride does get a bit more harsh. That's why I won't go any lower.
Even at 35mm I'v caught my sills and god knows what else on high kerbs and dips
i haven't touched the suspension on mine but lowering it would improve the looks of the car and increase the handling capabilities.you don't don't want to go over the top though and have it slammed.a nice set of alloys and lowered suspension would set it right off
