Aero recommendations for C5Z
I have a C5Z that is mostly HPDE driven and it is time to go for aero. Looking for any experience with different suppliers... wing, splitters, canards
Looking for a wing that does not extend past the body.
The car has full t1 kit with spherical bearings, 315 a7's square, ap brakes, and is driven hard well maybe too hard....
Thanks,
Bob

I built everything myself so I don't have experience with purchased stuff, but just wanted to to tell you to make sure you don't install a splitter before a wing for the track. I put my splitter on first and the car was awful on the track, very spooky to drive with the aero imbalance.

Agreed. You need to do both wing and splitter at the same time. Wings can be purchased but I have always found that making your own splitters is the best way to go. You can use plywood or Aluma-light but since a splitter is ultimately an expendable items, you are going to find that you want something that is strong enough to support you rocking the car with your foot while still breaking away easily in a bad off. There are a lot of threads here regarding the topic. Try searching "DYI Splitter"

I've installed 3 ACP front bumper/splitter assemblies and the fit has a lot to be desired of. The amount of extra time needed to sort things out isn't worth the cheaper pricing. If you just try to bolt the splitter to the fascia the splitter will be pointed the wrong way (uphill instead of downhill - front to back). On one car we were able to heat it and bend it down on another I had to make up my own spacers to get things to come out correctly.
I would highly recommend the Blackdog Racing fascia and splitter assembly IMO it's a much better design and there is minimal "extra work" needed to get it to fit, it's more expensive but worth it.
No matter what parts you go with you still need to come up with your own mounting solution, make sure that your mounting solution is adjustable - it will really help down the line to make sure the splitter is properly adjusted.
There are a lot of good wing set-ups out there some with frame mounts included. The Good Aero wing is the same one used by Danny Popp but it extends rearward past the bumper, but I would still check it out. Otherwise LG, Blackdog and ARP Performance all have decent options.

If you put an LS2, 3 or 7 in your C5 then the dry sump would become a necessity IMO.

If you're still running a LS6 then I really don't think a dry sump is necessary - there are a lot of really fast cars that ran/run there C5's with big time aero without issues. However it's never a bad idea, an accusump is really nice for pre-oiling but I really don't think it adds that much safety for starvation, the dry sump is really the only way to prevent starvation issues.

Check with RX-Ben to see what he's running in his C5 I believe he runs those tracks - he may be some help in the aero department as well.

Make your own splitter. For a Wong I chose kognition. You can make it any dimension you want. I kept mine at 70". I run slicks and a Ls3. No dry sump or accusump. It's a worked head/ motor car with drilled lifter trays. That's it.

Hard to believe no one has asked.....Why add aero for DE? It's going to cost a good deal of $ for a well designed wing, you'll either pay a good deal of $ or need to fab a splitter yourself, you're probably going to want to get adjustable shocks (and learn to adjust/tune them) for different tracks where you'll be adjusting aoa to take full advantage of the package. Plus, as others have mentioned, in your car now if you have an off you'll most-likely mow a little grass...pull through the pits for a quick check and be on your way. After Aero, you'll most likely be repairing something up front...more time and $ and probably a lost session or two while you at least clean up the mess of a front and pull the wing off so you can drive the rest of the day/weekend. It looks cool
and its a little faster but unless your chasing the clock (TT) or someone else (w2w), why bother? Please don't take this as a knock on what you want to do, and if it's what you want by all means take what others have suggested and go for it. But at least ask your self twice if it will be worth it for what you are wanting to do. 
If you do, certainly give AJ a call. Seems to be a hard-working, sincere guy that puts out quality products.

I've never heard anyone ask Scott why he sugar-coats everything.

I have a few points left in the class and need to catch a GTR (about 1 second to 1.5 faster most tracks), and figure the only way is to be MUCH faster in the corners cause he has me totaly out motored..... I have to fix crap all the time so a bit of areo repair not a big deal and offs have until very latly been few...

Alumalite is light and strong...but one F up and its toast.
