BRE Air dam

[geezer]

Thanks Arne. I'll post my evaluation of quality and fitment when I recieve it.

I think the better choice as far as period correct would be the ducted version. I've read, that to get around air dynamics rules BRE concieved the ducted version because brake cooling was allowed. The ducted version also must be more rigid in its construction adding strength. I took all this into consideration when making a choice. My Z will not be a daily driver, but only driven on occasion, when the urge arises, so wet brakes are not a concern so that didn't enter into my decision. I have an original BRE rear spoiler and I was more concerned with increasing the downforce on the front to balance the effect of the rear. As much as possible with period pieces anyhow. If I wasn't using the rear spoiler I would have went with the ducted spook. I'm a Z newb, reading & acting on what makes sense to me. Right or wrong, I'm not sure.

How's it going Ron? I have both ducted and non ducted from MSA. Both are perfect quality and fit, I like the ducted ones much better for looks and have bought another ducted spook for the 71 restoration. Guy

I only saw the MSA spook briefing so I can't say with absolute certainty, but it seems to me the BRE spook is a bit heavier and more rigid than the MSA spook. Frankly I don't think weight is an important concern for those that aren't racing. Rigidity of the structure is important to ensure proper function and mitigate cracking. Les gets many of his products made by the same companies as others, but that does not automatically mean that they are the same. I don't know how you can determine how the products are made unless you talk to Les and MSA.

Ron, your CZCC number is 12938. It's not obvious, but if you view your own profile the number is visible at the end of the URL.

Didn't realize we got a discount from MSA. How much is the club discount?

Well it would seem MSA's reason for wanting a club number has nothing to do with a club discount. They sent me a bill with the total amount including shipping and there was no mention of a discount.

[Arne]

I do get small club discounts from MSA on some items. But not on items which are already listed as "Sale" items. Which is frequently the case with their spook-copies.

This is the first time I've ever heard anyone mention a wet brake problem due to rain flowing through the ducts. Has anyone ever verified this? It's not like there isn't any water flying around under a Z without a spook and there is a shield. If this were a true safety issue, you think it would have been widely reported and the ducts discontinued years ago.

Probaby not a major concern for any of us. The BRE style vented spook available today is not a truly vented piece unless it is modified to be so. Earlier original BRE spooks were ducted and the airflow was aimed directly at the brakes. Logic dictates that if a wet air flow is directed to the brakes, braking performance will be affected. Maybe someone with a ducted spook will have first hand knowledge and has driven in heavy rain.

[Arne]

I think Ron is right. Since the modern spooks don't have the ducts completely finished, they don't aim the airflow directly at the brakes, but under the car instead. I have driven my car in the rain with my spook and did not notice any problems.

[Carl Beck]

Even with the original ducts - fully inclosed - you had to run duct tubing to the struts and aim it at the brakes... for brake cooling. No problem with the ducted spook in the rain...

FWIW,

My non-ducted BRE type spook from MSA was delivered today. I am more than happy with the quality layup of this part. Good value for the money in my opinion. Can't mock it up on the car yet, it's still on the rotisserie. Fast delivery too. Sometimes it takes more than a month to get something from the western US, but that is because of our Customs Inspections.
