You're forgetting a key element in your calculations: your current offset.
What's the offset on your 7.5" wheels?

We also have no idea what "your style" is.

Probably between et30&25 front and 25&20 rear.

Nope, lots of work still yet to be done. Still don't have the tires nailed down and even after that gets settled the wheels still need to be torn down and refinished.

I'm going out on a limb here but if he's not well 'versed' in offsets then it probably wouldn't be the best idea to point him in an aggressive direction with low offsets. Perhaps something in the high 30's low 40's to keep him from having to run stretched tires or doubling up on negative camber.

Looking' forward to how your new wheels will sit, hope you get it sorted soon, Rev.

Agreed that hi 30s & mid 40s are the safest, Dark. Wheel/tire fitments need a lot of tweaking if 'aggressive' is desired. That's where the beauty, challenge & fun are!

Well with BC coilovers (I also have them) about the lowest you can go on an 8" wheel is et40. But he wouldn't need stretched tires or excessive camber until he got below et30. Since the OP has BCs camber could easily be set at -1.5 to -1.75, which isn't excessive, and offsets in the high 20s become a consideration.

That's probably what he needed to hear

Once he knows roughly what the 'limits' are he'll be able to find a suitable set from there.

The offset I have now is +45 and I'm running 5mm spacers in the front so the wheel doesn't rub the coils.
I'm looking to get something like steelies 16x8 et25. Would I need to run a large amount of camber so I don't rub and what tire size would best for a decent stretch
My ideal ride style is hellaflush without a lot of camber so I can get some life out of my tires

+45 mm with 5 mm spacers = 40 mm offset.
Going from 7.5 to 8 in. width translates to 1/4 in. less offset (6.35 mm)
so figure about 33.5 mm or less offset would clear the coils.

But would it also clear the fenders from excessive rubbing

What tire are you running with those wheels? The reason I am asking is because I am running a 17x7.5 wheel (+45 offset) with BFG 215/45-17 tires and I get no rubbing whatsoever on my 2009 MCS. That is also with a 1.4" drop.

No rubbing because it's not a 'hella' flush setup, you're running a (very) conservative setup.

Glad I saw this post because the whole offset thing confuses me. Let me see if I understand. My OEM 16" 6 spoke twin star wheels have a +48 offset, I believe. The ASA AR1 wheels I got from Tire Rack with my winter tires have a +38 offset. That means that the ASA wheels are 10mm (25/64" or about 3/8") closer to the street side of the car? I assume the further out the tire is, the more effect the camber has on the angle of the tire tread to the pavement? The tire size for both summer and winter tires is 195/55-16 and I have no suspension modifications. I haven't experienced any tire rub on the fender. Should I be okay or are there potential problems like significantly more tire wear, etc?

+1. For reference 205 tread with = about 8" so for any sort of aggressive stretching you'd have to go to a thinner tire than that. My R53 has a slight rub in the back over jarring bumps with the stock 17x7 et42 running 205/45/17s with about a 2" drop. The front cant go that low for me since I have to clear a few speed bumps to get to my apt. I'm guessing my front is around a 1.5" drop. I elimiated all rake at my current stance so if anyone knows what the stock rake is I would actually know what the difference between front and rear are. With with 16x8s I dont think any wheel rub would be an issue.

EDIT: I just realized this is in the 2nd generation MINIs section. Whoops.

My setup may be considered conservative, but it is totally functional for handling and streetable purposes. Should I ever desire to race it, there is nothing I need to do to it. If someone is choosing to defy the suspension dynamics of their car just so it can set on the ground, more power to them. For me, I believe in form and function.

You don't need to justify your purchase to me, the OP wants a 'hella' flush setup and I pointed out that yours is anything but. Anyone knowledgable of aggressive stances understands that they aren't always the best performance choices.

With a wing that big I sincerely hope you have a desire to race it.

And I'm lol'ing at your form over function comment when you're sporting ccfl angel-eyes

Most of what you have stated here is incorrect. However, the short answer is yes ASAs with a +38 offset and 195/55/16 tires will fit and wear fine.

Technically a 16x8 et30 will sit flush to the fender. Honestly I don't know if it will live up to your hellaflush standards. I can say that even at full drop on your BC coilovers you will likely still have some wheel gap with a 205/40/16 tire.

Actually he said form and function which to an extent he has some of both, depending on taste. As far as low life standards? Probably not. But his stance is way better than stock, which is what really matters to me. Wheel gap is my mortal enemy.

I'd agree. Minus the blacking out. IMHO blacking out is played out and looks tacky. Otherwise, I'd say its a purpose built machine that I would love to call my own.
