You don;t have enough offset for the fronts ... ideally, @ 18 x 9.5 for the front, you want +45 (ET45) offset ... with only +15, the outer edge of the rim will be at least an inch outside the fender ... and the tyre will rub ...

Factory 19" wheels are 19 x 9 ET47 and rears are 19 x 10 ET30, so if you are going for 18 x 9.5 for the fronts, you will need something like ET45 but this would still need to be checked to make sure the tyre does not foul on the fender. 18 x 10.5 ET2 should be OK, but again, a trial fitment is required to make sure .....

Your choice of premium track-day tyres is much, much broader in 18" wheels - check the range of Bridgestone (RE055), Yokohama (A050, A048 and the new Neova AD-series), Dunlop (Direzza series) or even Hoosier if you want to support a US-based manufacturer.
