I know you're concerned about tyre wear but just wanted to share my experience. When I switched tyres in the MSE I also had more aggressive geometry added: -1.3 negative camber and +0.5 positive toe on front, +1.6 positive toe on the rear (all per tyre). Significant and very noticeable difference, handling feels much improved, turn in is incredible now, and you really feel the difference going around roundabouts (i.e. turning circle). I can only imagine its kind of what what rear wheel steering feels like on modern supercars.
I really get where you’re coming from with this setup as I have similar with some of my cars including my dailies.
I don’t know what the exact specs are without reaching for my walking stick and going to the filling cabinet but I am aware that my tyre life isn’t even close to what some owners say they get and to make it worst, I also always fit very soft tyres.
I’m happy to get between 5,000 and 10,000 k’s for a set depending on the car and the wear is always uneven but I see it all as the price I’m more than willing to pay to have a car that feels very engaging and responsive even with street driving.
Every day I drive through a very tight bend near my home and it’s very rare to see anything follow me through it at the 60kph speed limit, most back off to about 35-40 and those that try are unusually in all wheel drive Audi’s or nicely setup Porsches.
That bend never ceases to thrill me.
I know some people wouldn’t do this as they see dollars as more important but I’d rather have the fun instead of the money and when you only clock up a couple of thousand k’s a year on a car, tyre wear doesn’t matter compared to having a car that truly handles.
