I have read a lot of this thread but haven’t quite found the info I need. I am in the process of ordering Work Meister S1 3P.

R disk front (2mm clearance from calipers)
O disk rear.
20x10 front and 20x11 rear.

I was thinking to use small spacer to give the calipers more clearance. But Work got back to me and said for the front I have a choice of +25 or +38 (my current work wheels offset) and +42 in the rear.

was hoping to run a 285/30/20 or 295 front with a 305/30/20 rear.

Would that aggressive offsets work with the desired rubber? +25 seems very aggressive, so could do the +38 with a 5mm spacer for more clearance and more
Offset. +42 is only 3mm more aggressive than what I have now. I want front and rear to look even in poke.

I am currently on stock Magneride but will do BMR lowering springs in the future.

I'm not gonna say anything about the disks cuz I don't entirely understand them and how to tell fitment there...or if you need me to say anything about it lol.

+25 is super common for the front. Think about the 11" wide wheels that are sold specifically for the Mustang - they're always +26ish.

I run 19x10.5 +45 square with 305/30 on my Mustang. 20mm spacer up front, so essentially +25. Lowered on Steeda ultralite with Bilstein B6 dampers. I have a bit of poke (not as much as the PP2) at 1.7* of camber. Your setup with be 6.3mm further away from the strut and further inset than mine, so should be minimal poke, if any, and easy to get rid of with camber. I'd be hesitant of hitting the strut with the +38.

Those tires are shorter than the PP1 stock setup, so should be fine imo.

Sounds like you're good on the rears.

Use willtheyfit.com and whatever you're running currently as a starting point. You can input your values and the new but the biggest help is you're able to go out and actually look/feel around or measure.

Awesome mate thanks for that.

Pretty settled on ordering:
20x10 +25
20x11 +44

with your tyre setup i reckon I could go a 295/30 front without any rub. And that should match the 305/30 in terms of visual “stretch”.

Just used that site, what a great tool!! This wheel game is both a nightmare and a lot of fun.

You'll have to post pics when they come in. I'd considered some S1s, but I think I'm still gonna pony up for TEs one of these days.

I'd bet money those hit strut. And are also in no way considered aggressive fitment lol

No, because they WILL hit the strut. ET 40 is extremely close to the strut and some people get rubbing. No way a 10” ET48 gonna fit unless you have a custom strut or are running some camber bolts to push it out.
