Custom wheels, build your own?

[KennyT]

If you want good performance you need to run 15" wheels period. Everything larger is more expensive, heavier, and a compromise. Buy the wheels you like to look at and good street tires, then pick up a set of 15x8 track wheels and tires.

Sounds like you were not really after functional then

1+ buy some proper K1's if you want to track or search for some nice borbet type T they are wide.

These are what you want for perfect track wheels:
(I know pick up only, just an example)

I got billy sports, IE Stage 3 springs, and H&R drop hats waiting to be installed :)

looks like you need more low, and less rims. save your money.

[Ryan...]

I've already got someone coming to buy them pretty soon :D

They aren't the worst options, but I have my heart set on a specific rim right now.

your 17" Kosei wheels will look just fine! i'm going up to 17 for 'functionality'. lots of sticky 215 or 235 options, and less sidewall so better response. also, yours are very light so that helps as well.

[einstein57]

I hear yah. I think 17's look to big and 15's look to small. Nothing wrong with throwing on some 225/45/16s and calling it good. But you only get like 2 sticky tires to choose from.

I've got 17" Kosei K1s on right now, running 20mm spacers to make them fit. I really dislike how 17s look on the e30. while I want the rims to be functional and sized properly to allow me to run nice sticky tires when I want, I also want them to look nice. My car is driven 95% of the time on the hwy, and it will see AutoX a couple times this spring/summer.

16x9" wheels are not functional because you have to run a narrow tire or pull the fenders in order to make them fit. Your better off with a 17" wheel beacause of the larger tire selection. But then there is the additional weight. So basically the only functional performance wheel tire combo you can get (for the auto-x enthusiast) is a 15x8" wheel with some 225/45/15's. So you should just grab a cheap set of tirerack C1 wheels and call it a day.

[Ryan...]

No, I want it to be functional, but what i'm reading more of is that they're also heavier than most 16" rims, and I'll need to make modifications to prevent them from rubbing on stuff. If an 8" rim was just as "functional" as a 9" rim, I'd take the 9" because it'd also look better IMO.

[Ryan...]

oooo ok, that kinda sucks, I was excited to see how wide one could really go w/o major modifications :(

Guess my search continues!

[White325is]

Its not really functional either. You would need to grind the shit out of your front caliper bracket too. You can get something better for the same money.

[Stephen]

its worth noting too that diamond doesnt do odd sizes, so 16x9 is out.

[8380 Labs]

if you're going for functionality, then an 8" wide wheel with some 225s, conservatively spaced will do the trick.

say et25 front and et15 rear.
