[1mGator]

Hi everyone. Yes, I have read and searched for hours and still have a question. I just turned 21,000 miles and my tires are shot. I have stock rims and the car is lowered on H&R springs. Like others that have "tunes" I am looking for some more grip on the rear while maintaining great handling.

Data;
Stock front 245/35/19, 25.8, 807 rpm
Stock rear. 265/35/19, 25.3, 790 rpm
.5 height diff and 20mm stagger

Candidates for replacement;

BMW safety car set-up
Front 255/35/19, 26, 799rpm
Rear 285/30/19, 25.8, 807rpm
.2 height diff and 30mm stagger

Option 2
Front 275/30/19, 25.6, 814rpm
Rear 295/30/19, 26, 799rpm
.4 height diff and 20mm stagger
I think this would require 6 mm spacer at front

Option 3
Front 265/30/19, 25.3, 822rpm
Rear 295/30/19, 26, 799rpm
.7 height diff and 30 mm stagger

Ok, all combos are within the 3% rpm that Turner site recommends. I have no idea what the impact of height and stagger will accomplish (20mm versus 30mm) but I saw it was suggested to not go more than 30mm. I am also confused by width (what will fit with rim offset) as the michelin site had the sizes I am interested on different rim widths. I am not a track or autocross fanatic but love a spirited back road adventure.

I am targeting the Michelin Pilot Sport tires (make argument for others) as I was happy with the PS2.

Please tell me what I should go with and why.

Thank you all!!!!!!
