My 172 had a list of suspension mods which was as long as your arm.
My 1.2, over Dartmoor, was far quicker and more confident. I actually had people ask me when I'd done the F4R conversion, because they couldn't believe that it would outhandle a 172 in dem twisties. Usually someone who'd gone all out with coilovers and ARBs etc.
For driving on tracks and billiard tables, having a rock hard suspension is great. It feels like you're driving a go-kart. But in the real world with bumpy lanes you simply can't run suspension that hard without picking up wheels.
