225/45/15 vs 255/40/17 RS for autox

CrazyB, what were your impressions after this change? I'm considering something similar.

[CrazyB]

Yeah looks like I will not get to test the setup this weekend, as I came down with damn strep throat.
I hope to test it out on 4/1
I was thinking of after the actua runs do some fun runs with 15x8 with rs in 225 and maybe run with data logger to see true difference.

had i seen this before i would have recommended you stay 15". I find my 5-lug m3 17" (granted i'm running DS1 and DSIIs @ 22-23lb/e of just rim alone) really heavy. If it wasn't for my car being pretty light with an s52 i would have converted back to 4-lug.

I think i could have found a 4-lug 15" brake setup to match the performance of my current brakes, which in itself is really heavy too.. but oh well, budget beater. can't beat the route i took.

Hey CrazyB, do u have any pics of the fenders without the flares on it? Curious to see how much was cut away...

[CrazyB]

I am running the Ground Control camber plates so the caster is adjusted JUST enough to clear the front valance. It was just a tiny amount and now I only get rubbing on the inside of the wheel well on almost full lock (which really is only an issue when in grid or the pits).

Ordered some spec e30 plates, hoe this helps with front wheel fitment.

Tire Rack is advertising a new Kosei, the K4R.

17X8 = 14.8-15.8 lbs.

$199 apiece!

Now if there's a proper 4X100 and offset for STX e30s ...

Yea ill post some pics when i get them! Im hoping to do accents on the car the same colour as the wheels. Been working on a widebody for the car:



Some obvious trimming and sanding still need to be done, but its coming together!

[CrazyB]

That color will look pretty cool with the black car. Any plans for fenders?

I am running 20mm spacers with hubcentric rings. Ordered them from Tulip City Wheels (http://www.tulipcitywheels.com/tcwstore/). Super nice quality!

Awesome! thanks for the link. Just ordered hubcentric rings from them. And of course, These guys to go with them:

Gotcha, sadly I am running the ground control touring plates so caster is not adjustable.
Will have to look into this.

Looks awesome man! Did you bother with hubcentric rings?

How much clearancing did you have to do in the front to not rub on the turn in?
I am currently running into the issue of catching the edge of the valance on turn in.

I love my xxr 527's with 255's! For the price, you can't get a better deal!

Y'know, 19 lbs for a 17x9 is really not bad at all. It looks badass, it will be interesting to see what you think of the combo after an event. How was wheeldude to deal with? Were the wheels special order?

Wheels were special order, wheeldude was great and super helpful guys. Also a big plus is they are 15 minute drive from my office so no shipping needed.
