I've dropped the pressures on my
cupra to 2.1 bar (30.5 psi) and the ride has improved plus I get less wheelspin and wheel hop, also significantly less crashing over bumps.
Recently I read an article about Seat UK entering an ST
cupra in a hillclimb. The only modification being reducing front tyre pressures and increasing rears (to^increase grip^).
I havnt tried upping rear pressures yet but I may try dropping all pressures down to 2.0 bar.
Don't know why they have them so high in the first place.
