Looking for recommendations on rear spoiler.

[Pitt Stang]

This was the first year I tracked my 12 boss and would like to get a little more down force in the rear. I’m thinking a winter project might be buy an old rear deck lid somewhere and mount a bigger spoiler to it. Any recommendations on rear spoilers? I could buy a Laguna Seca style spoiler but don’t know if it’s worth all the effort how much additional downforce I’d get vs the standard basic boss rear spoiler which I have now.

I’m not opposed to drilling holes in the new used decklid so any of the pedestal types I’m open to but I’m looking for recommendations.

Thanks.

I would definitely go with a bigger wing than the LS as not sure that created much more than what came stock on your Boss. I like the idea of getting a trunk deck lid and placing a World Challenge or Grand Am style wings. I may be biased , though , but getting another deck lid is the key - I am looking for one so I can convert my Boss over to a C Prepared car if I want to autocross ( I need to go with a big spoiler ).

Good luck.

By Wang, I mean this one.........

Holy Wang...That's a big one!!!...

Yup! I got mine replaced!! went from a little one, tooo a huge one, in one step. Just learning what to do with it........

The cheap Steeda wing is by far the best bang/buck and makes A LOT of downforce. We raced them in Grand-Am forever and they were extremely impressive and effective for their price.

Take a look at Phoenix Racing's setups. Do that.

Absolutely,
generally speaking the IMSA wing and splitter should be paired
or
The PWC wing and splitter should be paired, to do otherwise will cause you issues

Did someone say BIG WING??

 

[Bill Pemberton]

Dang, and I thought my wing side plates were big ---------- nice job SBY Boss !!

This. Don't go overboard on rear downforce if you can't balance it at the front.

For price and ease of home-building, I'd do something like an NASCAR/autocross spoiler. I've seen them attached with hinges to the deck for adjusting angle. Or you could build it with overlapping, sliding panels to allow for adjusting height.

S197 SCCA CAM-C spoiler?

hopefully this is the right forum for this. i have a 2007 Shelby gt(glorified gt i know) ive had for years and recently got into scca. im currently in the process of giving it a fairly substantial overhaul. im currently working my way through the aero on it...finishing up a 6 inch(from body...

Dave has a good idea on the spoiler , though I would likely consider building a two piece item as you need a ton of height on an autocross circuit whereas maybe half as much works on a road course ---- you don't want to get to the point of inducing a ton of drag if you run some really fast courses, imho.

If you are looking for a pretty decent kammback spoiler, here's some ideas, the adjustable wickerbill can be used on anything, if it doesn't come up, it's page 9

Any idea if this wing (#476, I assume) is complimentary (balance-wise) in a car with no front aero except maybe a Tiger Racing / Chicane heat extracting hood? The current rear spoiler is a Roush 420011.

Thanks for the recommendations, folks!

As I recall that was the "spec" rear wing for the Boss 302 IMSA cars, so all you need to do is pair it with the front splitter for the same class/car

It certainly would. I'm pretty sure that hood reduces a lot of front lift (if not making a good amount of front downforce) so the Steeda wing would be significantly better than the Boss spoiler with that hood.

Thanks for the info. Looks like another off season purchase.
