What changes are folks making when they change from 18's to 19's?

I have the PSS9 set-up on my car. Also any recommended alignment setting for a good street ride.

Thanks!

 

Just an 18 to 19 change does not need to mean anything else suspension related .... unless there'ss something else you are also trying to accomplish.
And many of us run change back to 18s on track days anyway (with possibly a bit more negative camber dialed in).

I have 17s on the car now ..... winter fitments.
As for align specs ... I usually recomend start with the OE range and depart from that as your taste & use dictates, but others have opins on that.
Always get a print-out for your file of where it is left.
Use that for you reference for possible changes on the next align.

 

Seconding what Gregg said, you can certainly upgrade the wheels without modifying the suspension. With that said, many do these in conjunction as when you increase the wheel size, it creates the illusion of a larger gap between the fender and wheel due to the smaller tire.

 

if you track your car, don't bother. i went to 19"s and regret it and will be selling my 19"s to go back to 18"s...

 

Thanks Greg for the input. I was looking to see what the suspension guru's do when seeting up a car for 19's vice 18's. If anything?

 

I have both. The 18's for the track the 19's to look pretty

 

G, the 19's will be marginally bigger, so your only issue may be clearance with your agressive setup.
