help me pick wheels/tires for track days

[nanotech9]

Owned my 318is for at least 10 years now... used to autocross it a lot as a daily driver.  Now, it mostly sits and takes up space.  About once a year I take it for a lapping day at a local track.  My friends go and have newer/faster cars, and I'm envious of the traction they get from wider/better tires.

I've already got reasonable suspension (H&R springs, Koni adjustable shocks, and RD oversized sway bars all around etc.


Looking to go with a 15 or 16" wheel, as wide as possible w/o rubbing.   I'm not against rolling the inner fender lip but don't want to really affect the outer appearance if I can.  

IT won't get used a ton, so not looking to get into a $1500 wheel set... something in the $500 range + tires.


So, what are my options on wheels, offsets, and wheres my best tire selection (15" vs 16")?

I'm thinking at least som 215 or maybe 225 wide tires?

Running Falken Azenis in a 195 width and they just don't cut it anymore.  I can throw into a corner and get the front and rear loose at the same time  Fun, but slow.

Are you going to run same width front and rear?

you can check http://www.e30.de there is lots of project pictures with wheels details. If you are not planing brakes upgrade you can stick with R15 and go 8" at least or wider. Also depends are you running coilovers in rear or springs are in stock place. With stock you can fit 9" wheel at rear and probably wider tire than 225, but also check what tires available for your selected rim width.
I am not sure what you can buy street tires R15 wider than 225, but racing tire it is possible to buy.

yes - stock suspension locations.
