I would also recommend 1,7 tyre pressure on 4/4 with Contis. With 1,9 please try to break carefully when not in traffic in the wet. You could slip away. Plus you might get too much understeer in the wet. I drive 1.5 mm toe in and therefore have no wobbles, the car behaves nice in curves. Camber is zero and fine also.
I have added brake reaction bars at front and Avo shocks in the back. The adjustable Avos make the ride more stable and you get less roll of the back in curves. They also help to compensate the tendency that the rear springs at least on my car are too soft, and on normal bumbs the leaf spring touched the chassis without the Avos. Otherwise I tuned the shocks not becoming too hard, just so, that the spring does not touch the chassis.
No more changes and 15 000 happy Km driven.
I think in nearer future about the shorter 4.1 axle. The 3.73 (I need the last proof if it is really a 3,73, the plate on the diff is unfortunately unreadable) is too long in relation to the engine power.
My son drives a 1995 MX5 with 90 PS and a 4,1 diff ratio.. The ratios of the gearbox are the same as listet here in another thread with regards to the current 4/4. In addition the Mazda has 185/60/14 tyres. His car drives excellent, so I have no worries the the 4.1 diff could be too short when paired with the even bigger 185/80/15, which is a difference of ca. 10% in the direction of a longer ratio compared with his tyres.
Many happy miles for you. All changes should keep some time, just get familiar with her first. Only the issue with the tyre pressure should be solved before you get the first rain. I also will change the tyrs brand next spring.
P.S. today my son drove his MX5 with newish good normal road tyres, and I drove the 4/4. We paused somewhere, the surface oo the parking was a white sand. His tyres were white when parking, the tyres sticked it up. My Contis picked up nothing, almost dark and not sticky at all.
