Using the stock 219M rear wheel on the front actually should work. It's a 9.5 ET23. That means compared to the stock front wheel (8.5 ET29), your wheel will extend outboard another 16.7 mm and extend inboard another 8.7 mm. But considering that a 10 ET25 setup all around is pretty common for the track, which compared to stock would extend the wheel 23 mm outboard and 15 mm inboard, that should fit just fine.
Or you could save cash by getting a set of 18x10 ET25 APEX ARC-8s or EC-7s, which cost less than OEM, are proven at the track, and have the additional benefit of clearing BBK setups that the stock wheels won't.
