K1's but I have them on my car. When I was running it on street tires with the crappy tune I had estimated at 300 hp there is more than enough tire back there to do the job. It would take a ton of tire to get traction in 1st but that is any boosted car, and I am sure you do not want to run slicks and do hole shots.

I feel insulted, we used to be Myspace friends!

Anyway, let me break it down for you Barney-style. 225 on a 7 is not cramming, at all. 15x8 is not superior to a 15x7 (unless you are some turd track racer ) for a street car. It's all about side wall height and tire compound.

I had to be convinced of this, luckily I had a friend do it for me. He decided to show me what a two-step, death launch was like in his E30 (over 450wtq). The car hooked first on 14x6.5 wheel with a 235 tire and nearly broke my neck.

After I used a garden hose to clean out of my underwear I completely dropped my argument about why I needed 15x9 wheels for my car and he just laughed at me.

What viperormiata said is true. For straight lines.

I like turning too much to put 225's on a 7" wheel. Done it before.

Thanks for the input. I know 1st is pretty hard to get traction in, I just bought some new 205/50 Nitto NeoGen's so I'm hoping that will atleast give me full traction in 2nd. I know 1st will slip once the boost hits, but it is what it is. I'll worry about an LSD first, then once I can turn up the boost I'll look for something wider/stickier.

Right now I'm going to stick with 205/50's, I think that will get the job done until I get an LSD and turn up the boost. I know there is a lot of factors anyway instead of just a wider rim.

Sounds like you had a damn good time in your friend's E30. I need some friends that can walk on my Miata

I'll be doing a mix of both. But it is my DD after all.

Kosei's.

For lots of reasons but here's one most wouldn't consider - ease of cleaning! Kosei's are a breeze to wash compared to my 6uls.

The Kosei's are probably the best looking wheels on the NA - I'd refinish them from white to gunmetal or black though. That has to be a bitch to deal with everyday

I liked them best dirty after a trackday, covered in brakedust. I like the gunmetal finish produced by the XP8s.

Haha, I never thought about that until you said it, but yeah, these are a easy wheel to clean. I like the solid spokes, no need to get in any cracks

Yeah, they do get dirty pretty easily, but I love them white. I am thinkin' about filling in the curb rash and repainting them white as a matter of fact.

I couldn't be happier with them I'll be continuing the white scheme in a few other places as well.

Just a tid bit, TireRack now sell Kosei K1's with 25mm and 30mm offsets. This should push the wheels out further making them look even nicer. You can also get them in 12.4 pounds weight.

I'm thinking of painting mine white, they need a facelift anyway. A ton of wax should keep the cleanup to a minimum.

Spyder, how about some updated pictures ?
