Why did you choose 19's instead of 18's ?

I choose 19 rather than 18 because in my part of the world I cant source good tires, thus I have to order everytime so savings wouldnt be much. In tire selection yes there are more options but I'd rather stick to 19 which is the oem size and not to alter the handling of the car and imo I think 19's are the new 18's in the near future.

Update- Decided to cancel the bbs as I wanted to run them without spacers. I will be going with stock rims and will order the bbs e88 later.

The car is still at the dealer getting the brake pads, lines and fluid changed then suspension parts after that.
Will post pics of the suspension after they get installed and also the roll bar which is already installed. Then after that will give driving impressions on the street before taking it to the track.

I just came back from the dealer and all the suspension parts, brake pads, lines etc have been installed. They are in the middle of the alignment but I have a problem, Porsche measures toe in degress and I have them in mm. I searched but couldnt find how to convert mm to degrees or minutes. Can anyone help me in that matter please. Toe in mm to be converted is below;

Front : 2mm out (1mm per side)
Rear : 4mm in (2mm per side)

Thanks

So just to confirm for the front I should run 0.20 degrees per side, 0.4 total and the rear 0.25 degrees per side, 0.50 degrees total.

For me and other track alignments that much front toe is a little much. Most run either zero toe to around .5mm out per side.... 2mm in per side is the max toe that has been suggested to me for a 997 car.

2mm toe in the front per side would turn your car into an oversteer beast
