Anyone out there running 235's on their concaves yet?

I've got 235 S-drives in the garage waiting to go on my concaves. Hopefully tomorrow!

Looks Perfect. Just got mine today and looking for different options of tire sizes. Do you mind telling me what tires are on your setup?

[jon volk]

There's plenty of material left. They're not gonna fall apart...

[dpmcdonald]

You'll need to grind quite a bit material if you don't use spacers. I still prefer this to spacers.

Oh wow... I'd be scared of the impact to the structural strength of those brackets. Last thing I would want is for my front brakes to go out on me.

Car looks great though!

Beware if running 5mm spacers. Whatever of the hub lip is left after you removed 5mm might not be enough to keep the wheel centered if it has a large bevel around its center bore. Say goodbye to hubcentricity. ;-) Some wheels have a smallish bevel. Some have a larger one...

I have the Ground Control kit with the Street Touring plates.

Thank you, I was really trying to determine what kind of drop you have in comparison to stock, but since my wheels will be here next week, I guess I can wait :p

[jon volk]

I was under the same impression but I don't mind the little baby spacer. I'm sure you can shave the bridge down a little bit to make it clear without really sacrificing the strength.

That is my plan after seeing the area affected. Id prefer that option to spacers.

What is your suspension setup? (If you don't mind me asking)

I don't want to steal anyone's thunder but I spoke with Matt regarding this.

I'm running a UUC BBK, and the concave version of these wheels.

I was told even with the UUC BBK I should only need a 5mm Spacer, however the first gentleman here (with the red car) also said he needed to run a 5mm spacer as well. If you wanted a set without the need for spacers and BBK clearance the flat faced were the ideal choice. Realistically a 5mm Spacer isn't a big deal imo. Personally I am more concerned if the tires will rub with the required spacer.

For the groups knowledge I haven't test fitted these wheels yet with my BBK.

Everything you said. When I was first deciding on concave or not, Matt and UUC did template tests with the flat face Arc-8. Flat face will clear the biggest BBK on the market for a 4 lug e30. Concave would not.

I'm sure you could grind down that portion of the bracket a hair on the OE brake caliper, but I can see why one wouldn't want to do that.

I see. Well, I don't want to run a spacer and bought these under the impression I wouldn't have to. I was told these wheels would even clear a BBK.

Matt, can you chime in here?

[dpmcdonald]

Yes, I had to use a 5mm spacer to clear my front brakes. A 3mm spacer might work, but i had a pair of 5mm already.
