Do you drive in the rain? Do you participate in track days or autocross?Is your car lowered?
I have multiple sets of Evo Enkeis. I have a set with Bridgestone Potenza RE760 tires that seem fine in everyday type of driving. I only have them because they were nearly new for $200. They perform well from spring to fall. They also perform well in the rain with little road noise.
My personal favorite for autocross and track days would be the Dunlop z2. An absolutely fantastic tire that meets the minimum tread wear for my classing. Excellent grip in a multitude of temperature ranges and decent in wet weather for a dry tire. They also have really good response when they are reaching their limit.
I run 235/45/17 for the Potenza (normal street driving), and 245/40/17 on the Dunlops. I have a stock ride height that needed a light fender roll in the rear to accommodate the 245 Dunlops for hard cornering.
Think of your budget and how long you want the tire to last. If I did not worry about costs, I would run the Dunlop on the street as well. They also have a rather good price point with superior performance to other tires in it's class. Keep in mind, the lower the tread wear (better grip), the less life they will have.
Feel free to check out the white 2g in my profile for pics. Any action shots (on pavement) are the 245 Dunlop, and stills are 235 Potenza.
Im currently running 215/45r17 with extenza hp. I was really lookin for an autocross tire for maximum grip I can get for wet and dry that looks good fitment wise
This thread has long been dead but I started working on this anyway. I think that it will be very beneficial to DSMers looking to get into autox and hopefully can also serve as a quick reference guide for current autoxers as well since most of us are only familiar with our own classes.
Please go through and let me know if anything is incorrect or should be changed or added. I don't care if it sounds nit-picky or minor, I want to make this article really good and useful. I am pretty new to the sport myself and am also no longer autoxing my DSM and am instead racing my Evo in STU, so that is what I am most familiar with.
I have a few clarifications to ask about right off the bat. What class would aftermarket cams move you into? Level 1 Prepared? Also what about stroker motors? if you know of any other common DSM mods that aren't covered let me know also and I will add them.
Without further adu (sp?), here is what I've got so far:

You must be logged in to view this image or video.
Below is a quick reference guide for selecting an SCCA SOLO Autocross class. For full rules, download the 2012 SCCA Rulebook. The following guide applies to the 1990-1999 Mitsubishi Eclipse, Eagle Talon, and Plymouth Laser models. Any modification in a lower class can also be used in a higher class. Any modification not specifically allowed is prohibited.
But first, what is Autocross? Autocross is a type of amateur racing event focusing both on driver skill and vehicle handling and performance. Most Autocross events take place in parking lots or abandoned airfields with cones laying out the course. Because of this they are found all over the country and are more affordable then road course racing events. They generally feature speeds no faster the what you would encounter on a public highway. Autocross events build driver skill, provide an safe outlet for performance driving, and invoke some serious competition!
SCCA Autocross, also called SOLO, is based on a PAX index, which is basically a handicap designed to equalize all cars and focus on the driver's skill. Cars are placed into classes based on the type of car and modifications done. Each class is assigned a PAX modifier which is multiplied to your raw lap time to equal your PAX time, which is what is scored. For instance, an all stock GSX in DS has a PAX of .821 while an all stock GS has a PAX of .799. If the GSX ran the course in 60 seconds, his PAX time would be 49.26 (60x.821=49.26). So, for the GS to beat him, he would only need to run faster then a 61.65 (49.26/.799=61.65).

Stock Class:
The stock class provides a nice way to be compete without spending a whole bunch of money on performance parts. However, since most DSM's are now 13-23 years old, they have at least a few modifications done that will bump them up in class. Even something as simple as a hacked air can, a downpipe, or a performance clutch will prevent you from being eligible to compete in the stock class. In the stock class you can run DOT legal R-comp tires such as the Hoosier A6, Goodyear Eagle RS, Hankook Z214, and Kumho V710.

Street Touring Class:
The street touring class is designed around using normal, every day street tires. It is for this reason that it has a nice low PAX and also allows for a large number of basic modifications to help turn your daily driver or street car into a well-rounded autox car. It is also generally a very affordable class to race in with basic mods most people do anyway and without the high cost of dedicated track wheels and tires. The tires of choice for street touring are the Dunlop Direzza Sport Z1 Star Spec and the Hankook R-S3, although any extreme/max performance summer tire will still work well.

Street Prepared Class:
The street prepared class is where you start to see some more power and are again allowed to race on DOT legal R-compound tires. You can up the boost and add in the supporting mods like fuel, clutch, and intercooler. However, the added power can often be more of a hindrance then a help to new drivers. If that is the case, focus on the skills and seat time instead of more performance parts.

Street Modified Class:
To be fully built in the street modified class takes a lot of time and money. It also pushes the border between street car and race car. Yet in spite of this, most DSMers wind up in this class due to previous mods. A carbon fiber hood, turbo upgrade, or atmospherically vented BOV by themselves will land you in this class. If you find yourself here, don't despair, it just means you have the ability to do more mods without jumping classes! The big thing here is upgraded turbos. Chose wisely and try to balance between quick spool and high power!

What would also be a good winter tire?
Id rather have it cut through snow and slush. If dunlops are in my budget then what ate the best for that
Most likely street prepaired class, maybe street modified class is what im goin for
