Offset help for F14s SDC

Hey folks,

I've decided to take the plunge on a set of Forgestar Super Deep Concaves for my E92 but I'm really struggling when it comes to the best offsets so if anyone has any experience id love to hear from you?

Requirements:
1) I have near new 265/30/19 and 295/30/19 Michelin PSS rubber I want to reuse on the new wheels
2) I'm about to fit a KW sleeve over kit for a decent drop
3) I can't use spacers (illegal) and I want to be pretty flush with the fender but not rub
4) I don't want a stretched tire (I like the rim protecting strip on the tires to be effective)

So.... these factors have lead me to think 9.5" front and 11" rear is the way to go but I'm open to suggestion on this?

As for offsets for such wheels... the floor is all yours folks...

I have F14s also
19x10+25 deep concave with 265/35
19x11+33 super deep concave with 305/30
I went with the two different concaves because I didn't like the super deep all the way around

Thanks! :-) Are you lowered and do you sit pretty flush? I don't suppose you have any pics?

I personally think it's the perfect fitment I'm on Stock ZCP suspension

Thanks for pics... I agree, that does indeed look pretty much perfect! :-)

Tell me, would you have needed to change the offset upfront if you went SDC rather than DC or would it stay the same (ie. Do the wheels fit differently for some reason)?

I am running 19X10ET20 all around with a 12MM spacer in the back. Et25 in the front may require a 5mm spacer to clear some Coilovers like KW.

Going SDC in the front will be different. Depending if you want/have a BBK you will be kinda of forced to do a low offset, which means a 265 tire won't fit well.

I just ordered SDC all around 19x9.5 et 13front (245/35/19) 19x11 et 26 (295/30/19) in the rear.

If you wanted to do a 265 tire you'll need to go to like a et 18 or 20 (not 100% sure), but then I dont think youll be able to clear the brakes if you had a BBK.

Thanks guys... that's great advice. I think I've landed on 11" ET 27 for the rear but the front is still undecided.

I'm not going to be going for a BBK as I'm primarily a street driver (with only occasional track time) so I'm thinking perhaps a 10" ET20

I'm running pretty much exactly the set up you're talking about- SDC F14s all around, 19x9.5 ET 18 with 265/30 and 19x11 ET 25 with 295/30 PSS, on KW sleeve. I wanted to do 275/30 on the front, but they were on backorder when I was looking. A couple points:

-the front offset is just about perfect to be flush, and I have no rubbing issues. But with a 265/30 on a 9.5, it doesn't give me a ton of rim protection (I scratched one of my fronts recently ) Again, I'd have preferred 275s.
-my rears do rub on large bumps occasionally (I'm pretty far down on the sleeves, less than a finger width gap). If I had to do it again, I'd go with something more like an ET 29.

These are the best pics I have right now to show the side profile.
