Rebuilding SSR Agle Premiums

[Creation]

I'm not sure if aftermarket lips will work. Thanks for the calculator.

Any input would be appreciated.

Do aftermarket(Triangle) lips work?

[Creation]

Hey SW,

I've got a set of SSR Agle Premiums I picked up a few months ago and am ready to rebuild them for my very strange fitment needs and of course more wide and more lip!

Currently they are:
19x8.5 et38 (1.5 inch lip) (includes ~15mm of backpad) - also running a 32mm spacer
19x9.5 et43 (2.5 inch lip) - also running a 38mm spacer.

With spacers, I'm close to my ideal fitment the only thing i'd like is a bit more poke and then I'll work on the dialing in of suspension etc.

So if my math serves me correct, I'd need the following to pull this off.

I'm looking to build the fronts for 9.5. Which should be easy. Move the front faces to the 9.5 lip/barrel. By doing so this should bring me to ~9.5 et 20?

For the rears, I'd like to go 11 1/2 with a 4.5 inch lip rather than the 2.5 inch and keep the current barrel. The end result should put me right at 19x11.5 et 18?

Mainly my question is, where can I source the replacement lips? They are 40 hole step lips.

Also, does my math seem correct?

I've done all the test fitting needed to ensure these new spec wheels will fit and without spacers, the barrels do not rub on any part of the suspension.
Thanks in advance for the help, I'm just trying to better suit myself and avoid any surprises.
I've read through all the tutorials and this is where it got me.
