It does change the steering somewhat. I'm running 20mm front and 25mm rear, HR Springs. I don't know how to describe it exactly, but steering feel is definitely different. Stiffer, almost.

Thanks for everyone's advice!
I may just go with 20mm all around to keep things even lol (My OCD)
So which brand is the best in quality? (Don't mind spending a little more for a longer lasting part)

I used to have 20mm all around with my stock wheels and swift springs and wish that i had gotten the 20/25 setup. The rears IMO need the 25 to match how the front looks as far as wheel poke. I also had the H&R Springs brand without stud replacements.

By moving the wheel 20mm to the outside of the car you are changing a few things:

(1) Scrub radius: Under braking, the front wheels will tend to react stronger to any grooves in the pavement and you will need to make more corrections to brake straight.
(2) Wheel rate (spring rate at the wheel) is reduced a little (softer). Since the tire is extended 20mm out, it has a little more leverage on the suspension.
(3) It is harder on the front hub bearings, but will take a while to show up.

I think it is a high price to pay for your tires to be more flush with the fender, but I am old.

I have Volks TE37sl 19x10.5 +22 with 25mm H&R Trak spacers in the rears.
Car is lowered on Swift springs and im also running 305 / 30 / 19 tires with no rubbing at all.

Fronts are 19x9.5 +22 with 20mm H&R Trak Spacers with 255 / 35 / 19.
no issues at all.

Spacers will change the scrub radius. That's the difference between where the king pin axis and the tire center touch the ground. The closer the better. I don't know if the Z tire point is inboard or outboard of the king pin axis point.

And I wish I had read the entire thread before posting this...
