These will work won't they?
 

17*8 40 offset in front
17*9 40 offset in rear

If so, what size tires should I run?

Thanks.

They'll work -- 225/45 and 255/40 or 235/45 and 265/40.

You won't have anymore grip in the front than stock and your car will understeer a little with that setup.

What would be the "optimum" offset for -

8'' or 9'' in front

and

9'' or 9.5'' in back

I'm trying to get some new rims, but I want to make sure I won't comprimise anything.

Currently I am running with Tein springs, about a 1'' drop.

Well, the "optimum" would be +50, which is the stock offset. Unfortunately, very few wheels are made with an offset that high, so we make compromises.

Generally, acceptable offsets are:

front:
8-8.5": +40 to +50
9": +45 to +50
9.5-10": +50 (coilovers required for 10")

rear:
9": +38 to +50
9.5": +40 to +50
10": +45 to +50

I run 8.5/9.5" with +45 offset and I consider that as low an offset as I would want to run.

Excellent help! I just hope they make the RP03's with that offset. I think I can get 8.5 in front with a 40 and a 9.5 in the rear with a 40 offset as well. I'll have to be patient, they won't be in the US for a few months. Thanks again.
