The E36 M3 is hard to beat for a practical street/track car. It handles great, has great aftermarket support and is relatively light. For years, the bread-and-butter E36 track set-up has been 245/40-17s on 17x8.5 40mm offset Kosei K1 Racing wheels. As drivers of this vehicle already know, the larger front size provides more neutral handling.
The K1 Racing has been a great wheel with one minor issue - no center caps. If your E36 M3 is purely a track car, this isn't a big deal. However, if you run your car mostly on the street and prefer more of a finished look, you may want to consider the new 17x8.5 40mm offset Kosei K4R.
With its nine-spoke design, the K4R has a different look compared to the K1 Racing. More spokes typically means more strength, which demonstrates the K4R only adds to Kosei's record of providing strength, value and durability. Also, the K4R weighs in at 15.4 lbs. compared to 16.8 lbs. for the K1 Racing.
For someone that does a mixture of street, track and autocross driving on a single set of tires, it's hard to beat the Dunlop Direzza Sport Z1 Star Spec. The tire provides a very sticky grip, is versatile and is available at an affordable price. Currently, 245/40-17 Z1 Star Specs mounted and balanced on a set of 17x8.5 40mm offset Kosei K4R wheels is available for only $1,512.**
