Just found a 17x9 +22 set which brings me to my next question - is 9 waaay too wide for the front? No matter what tyre I wrap it it?

YEP!

track_mr2, so +35 is a no go if I'll be going for Teins? Or will I still be able to have +35 at the back and figure something out for the front?

Okay I'll give you a  bit of a run through. It's a combination of you suspension, rim size, width and tyre size.
So with coilovers (tein others will vary) at the front 17x8 +35 will basically touch the springs by a few millimetres, its a very small amount of space you have to deal with. With 17x9 +35 on the rear they will fit perfectly pretty much and you should be able to run a 255 wide tyre with rolled rear guards and no rubbing.
I have two sets of wheels. My front are 17x7.5 +35, they fit without hitting anything and my rears are 18x9 +35 and they fit perfect. On my other rims I have 17x8 +28 front and 17x9 +35 rear and they fit perfect also.
If you run 17x8 +35 on the front with standard suspension they will fit without hitting the strut from the side of the rim, however height of the tyre becomes an issue so it doesn't hit the spring perch so you end up being limited to a tyre that needs to be stretched unless you bend the spring perch upward. On a 17x8 rim ideally you want to run a 235/40/17 tyre, however you will probably find you need to run a 215/40/17 up front to stop it hitting the spring perch that sits over the top of the tyre. With coilovers you don't have that issue but with a +35 the rim will hit the inner suspension. Also you may find that when turning the wheel it rubs the inner guard plastic. Depends on the bodykit you have.
Trying the house a 8inch wide front with 235/40/17's is very tricky, you need the perfect offset otherwise it will hit something or rub, for me with teins, 17x8 +28 is the perfect offset, as my 235's don't rub or hit anything. Different coilovers have different widths so it could be better or worse for clearance as its only millimetres you have to play with.

^^ is that all with rpf1s?

They are an awesome rim....

Na this is with different rims. I don't have rpf1s.

I ordered RPF1s and just went 16x7 +35 up front and 16x8 +38 in the rear... meh play it safe, plus I prefer 16s over 17s. They only came in silver so I'll be powder coating them matt black.

They are awesome. I have no fitment issues with 17x8 +35 running teins. That's on a rays rim.

What teins do you have? also what size tyre are you using?

I'm currently about to abandon my GTST/GTR wheel combo purely because I cannot get a quality tire in 16" to fit those rims.

I think I'm getting the hang of it now.
Checked out your picture - the fitment is basically perfect! But that sizing limits me so much to what I can get! Been trying to find a nice 17x8 +28 rim but no luck so far...
I'm thinking of going with the +35 offset for now and hope for the best when I do get Teins (5SGTE is saying he has no problems with Teins and +35 offset wheels) and in the worst case scenario go with the BC Racing coilovers (are they as good as Teins?)

Where did you find a 17x8 +35 Rays rim?!
