Hey everyone. I have taller and wider Michelin PSS tyres in the rear 285/35 and wider in the front 235.
I am trying to figure out if I have to alter my height as I want to shoot for ROW. 144f/127r..
even though tyres are taller do I still adjust height to these values from the measuring points or do I change these values a bit because of taller tyres?
when I set these values the front looks very high compared to the rear.
Thanks

A point of concern is the rotational differences between the front and rear compared to stock. This can cause issues with the ABS computer and especially on AWD versions Check sites like Tirerack for rotations per mile for your tire sizes.

You want the car as low as possible but the taller and wider the tire and the softer the suspension the higher that ride height will have to be
the tires you have chosen are a poor fit for a 993 because of the tire od, these incy high inertial and gearing costs.

245/35 & 285/30 on 8.5 & 10 are he 18" sizes to use w/o incurring ride height, inertial or gearing penalties
