I'm wondering if the programmed front-to-rear brake proportioning is non-adaptive, and is perhaps biased to expect larger tires at the back end.
What's got me wondering is that, thinking that more traction in front would be a good thing, I mounted my 205x50 on the front (Rota Slipstream w/ 5mm spacer) and the 195x50 at the back. Tires are at 37 lbs cold, about 40 when driving.
This seems fine for cornering and acceleration, but with rainy weather, I'm finding that the rear tires come loose well before the front under braking - today I even got a message on the display "Low Traction" - when the back came unstuck during some moderate braking. I'd have expected more balanced braking, with all four coming loose at about the same time.
I'm starting to think this reverse stagger might not be such a great idea on the Spark EV. Anyone got in-depth knowledge about the EV's brake management?
