That's it. I'll take one. Now for the size questions....

Are the heights for the Camaro versions measured from the top of the hatch or the fenders? You can see what I'm getting at as the Camaro hatch slopes down about 3" below flush.

In short, I'm thinking about the 10" instead of the 7" since I'm in the process of addressing the front in a big way right now. Have any of your customers with the 7" on a Camaro had a really big splitter in front? When I'm done with the front I'm concerned about being able to balance out the rear. I'd rather have a spoiler that's a little too long and run it at a more layed back angle (even though that's slightly less efficient) than get everything built and find the car is tailhappy at high speed even with it vertical. If I'm going to err in one way or the other I'd rather err on having too much in the rear.

Is my reasoning on track here Alan? I'm not too concerned if I knock off an extra couple MPH at the end of the front straight...I'll be going too damn fast there anyway. Has anybody used larger than 7" on the track? Or do you think the 7" when set vertical will keep up with anything I can do to the front?

For those who haven't, check out Volume 15, numbers 2 and 3 HERE. Personally I didn't realize the angle of the spoiler made such a huge difference. The adjustable angle will be a hugely useful tool for those of us without wind tunnels. My current Freedom Design spoiler stands close to 8" off the rear hatch but it's layed back at around 30 degrees. Probably a good match for front breather/airdam front but there's no way it'll keep up with a splitter added to the front.



Jon -

I read those very same articles last year!

I think I can provide a bit of feedback on the effectiveness of the 7" spoiler. I ran that spoiler on the red car in both CMC and AI trim and I run it on the yellow car in CMC trim.

The red car in CMC trim didn't have any aero work up front, so I ran it at about 60 degrees. Anything more and I picked up a bit of a high speed push.

(IMG:http://gallery.noid.org/albums/album23/Picture_007.sized.jpg)

In AI trim without any aero work up front, we kept the spoiler in about the same location:

(IMG:http://gallery.noid.org/albums/album09/picture03.sized.jpg)

Once we added the front skirt tho, that made it a completely different animal. We stood the spoiler all the way up and then taped down the edges to prevent air spillage around the edges and that just about balanced things out (see the bpic below). I don't think we had a chance to run the car balls out with the radiator exhaust exiting over the hood, but we expected to have had more front end grip requiring more in the back (or less in the front).

(IMG:http://gallery.noid.org/albums/album09/picture02.jpg)

The yellow CMC car has the same wing, but I've added a front skirt around the radiator deflector. I think I'm running this car's spoiler a bit more upright than on the red car in CMC trim but I can't remember off hand.

So, in a nutshell, the 7" one seems to be Ok with the airdam up front, but I think once you start to get psychotic with it, you'll want a longer spoiler. You can always trim to fit if you needed to.

Hope that helps!

Alan, I think I like the idea of having some extra that can be trimmed. Will there be any problems with the lexan folding over if it extends too much higher than the brackets?


Jon - With a 3" span of Lexan pulled down by 36" of its width by 44#, I measured 3/8" deflection at the load point. Here's a pic of the setup:

I believe the deflection will be negligible even at 10" height. The Lexan is tough, and will not care about the loading.

Alan,

I have been thinking of replacing my LGM rear spoiler. It is more looks that effective at this point. But, you know me, looks is important to me (IMG:http://www.frrax.com/rrforum/style_emoticons/default/ph34r.gif) (just vain I guess). I don't like the look of the removed stock flat "spoiler" with the Lexan set up, but I do like the look on Julie's Trans-Am. What would the effectivness be do you think with your set up ON TOP of the stock flat spoiler sitting like the LGM sits now?

Thanks

Yes it did, very much! Thanks!

I guess it's a 10" for me then Alan. It looks more than strong enough--thanks for checking that out.

Randy - You would lose the weight savings from the loss of the OEM spoiler, but if you blocked the gap between the OEM spoiler and the decklid the BF spoiler should should work just fine - maybe better since it would be several inches higher into the airstream. I'd block the gap with an aluminum or CF sheet that blended the leading edge of the OEM spoiler into the decklid near the glass margin

I think the Z28 looks fine with the BF spoiler filling in the gap between the fender 'bat ears', but I agree the T/A looks great - like it came from the factory with the BF wing on it. The 3rd gens should look really good too since it's a straight shot across the decklid and fenders.

Yes, thanks a bunch, Nick! OK 10" it is for you Jon.

The stars must be aligning or something...it appears I've already sold my Freedom Design spoiler and I wasn't even trying yet! It's still on the car. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/biggrin.gif)

Yeah, but it would be lighter than my CURRENT LGM spoiler....and more effective....I DID think about it being higher after I typed that last one....which is good......however, sealing that slit would be a PITA!

Sealing the underwing could be as simple as duct taping a length of rollbar padding in there, but a blockoff panel would look better - I'd be glad to fab one for you that would pop rivet in place.

Thanks for the order, Cass - and welcome to FRRAX! A lot of us here own Ybods too - it's a bit of a natural progression ;-)

The GP is now at the 20% discount level, any other takers? I'll leave it open thru Sunday.

Thanks,
Alan

Here's one from yesterday at Thunderhill - the spoiler is covered with raindrops:

(IMG:http://members.cruzio.com/~ablaine/sTAwing.jpg)

And a closeup at the shop - I'll be supplying adhesive backed black rubber or plastic discs to seal the holes in the decklid left from OEM fasteners and harness passthru. I also supply a resistor to plug into the 3rd brake light harness to keep ABS happy:

OK - Here is where we are today - please review the model and height that I have you down for and correct me if it's not right. Jon A and Cass M please PM me with your ship to ZIP. Randy I realized you expressed interest but not commit yet so if you decide against it there will be one available. I will go with the 20% level pricing since I said I would, and I think the last one will get sold one way or the other and allow me to fully utilize the sheet of Lexan.

I'll calculate shipping cost and PM a request for payment today - please send payment ASAP. I should have the Lexan in house by next Monday and start shipping by the end of next week.

Andy J - got ZIP Z28 ORR 5"
Jon A Z28 RR 10"
Brad S - got ZIP Z28 RR 7.5"
John D - got ZIP Z28 RR 7.5"
Randy M - interested? Z28 RR 7.5" top of OEM wing
Cass M - C5 RR 5"

Regards,
Alan Blaine

Sorry - that model Pontiac has an OEM spoiler that is integrated into the hatch - no way to remove it cleanly, so I can't make one for this car, unless you pick up a T/A hatch for it.

Hey thanks for thinking of my Alan! However, the budget is getting squeezed again. I have some repair from the last weekend coming, and I STILL haven't paid for all the off season upgrades yet. I would like to get out and dial in Jason's new rear shock setup and see where we go from there. I will likely be looking for more rear wing later this year.

My stock spoiler with the Freedom Design spoiler attached weighs around 19 lbs as near as I can tell. The little trim piece that you need to take off to remove the spoiler weighs 3 lbs. Some easy weight savings.

No sweat, Boyce - in fact I do have one more spoiler available on the GP, so you got some much needed luck!
PM me with your ZIP and I'll send
