I mounted the TE37s I purchased last month to check for fit. The specs are:
18x9.5 ET28: 265/35 BFG
18x10.5 ET30: 285/30 BFG
Suspension is stock for the time being. (I don't want coilovers on this car--at least not yet.)
I might run spacers in the back, but haven't decided what size...
Here are some pics, including the stock 19" wheels with PSCs on for comparison.
