Herrafrush winter setup

[Atomic Rooster]

Help me find some winter wheels for my <very> lowered BRZ! There's some camber on it too since it's a track car. I have 2 questions about this.

My summer setup is 17x9 +35 wheels (245/40R17), and I'm hoping to find some stockish width wheels for winter tires that are match my current flushness.

-If I go with a 17x7 or 17x7.5 wheel (215/45R17), that means that I'll need an offset of about +10? Did I calculate that right?

-What websites can I find that allow for searches by offset that actually has a good selection of wheels?


Some backgroud info & details:
I had my eye on some Sparco Trofeo 5 17x7.5 +48, but it looks like I'd need one hell of a bolt on spacer (38mm).

Since these are for winter, I'm not all that interested in super expensive forged wheels. Cast stuff (Enkei) or equivalent is fine.

The car is Red. I'd prefer Bronze wheels. Silver would be ok too.

Camber is about -2.5 front, and about -2 rear. No, I don't care even slightly about winter tire wear. Rear fenders were slightly pulled to fit 255/40R17 via gentle rubbing

If you live in Canada, i guess that means that you'll actually see winter temps/ice/snow
, thus you may actually care about grip & ground clearance, at least during winter season.

For clearance .. if you are not against redoing alignment, i'd rise her back for winter. Yes, at expense of worse acceleration due much bigger diameter and much duller steering due very high profile sidewalls you can get some of your mentioned "<very> lowering" back, but it doesn't seem best possible choice, especially because staying low won't do anything with shortened shock travel. Better more "normal" tire sizes but not herra-low. Maximum diameter wise on stock wheels/suspension 225/55/17 rubs, 225/50/17 was fine. Of course that won't give you info even for starting point to think of clearance/flushness, due having non standard camber & lowering.

For actual grip, on snow/ice, imho better to go as narrow tire as possible, due our cars being relatively light. BTW, smaller wheel tires also cost less. So how about getting 16x7 Sparco Terra instead of those 17x7.5 Trofeos? Rally looks as free bonus.

And fit some very recently released hakkapeliitas 9 205/55/R16 on those if studded are allowed, or hakkas R2 / Blizzak WS80 / Michelin X-Ice Xi3, if studless?

I myself also have track-ish camber (-3F,-2.5R), but leaving it as is even in winter (though of course less camber would enhance contact patch in winter, due tire never having as much flex prior grip-loss, as on summer tarmac). But it's simpler for me ground clearance wise, as i'm still having suspension at stock height (but even then at some situations in winter i wished for a bit more clearance).

P.S.
Sorry about saying NOTHING in post about offset/flushness that you asked, but imho in winter one should rather care about grip to not crash, instead of looks, quickly covered with salted dirty snow at that.

Yes, your calculations correct for a 17x7. 17x7.5 would be +15ish. Not many wheels in those offsets, your best bet would be bolt on spacers.

Thanks guys!

I'll probably raise it up a bit, but I won't redo the alignment. I won't be putting on many km.
