I have a set of M&H Racemasters 24.5x9.2x15 that I run and they are awesome. As Steve said you will need to run coilovers to do it right. I ran 1/4" wheel spacers and it worked alright but running spacers is not the best option.
I'd be willing to let these slicks go for a fair price as I'm going to go bigger when my car is back up and running this season.
