Fiesta R5 Carbon spoiler and carbon wrapped pieces

Yes the carbon spoiler is the exact replica used on the R5. It is produced by Cestra Racing based in Italy. I purchased the brackets that have to be welded to the tailgate directly from M-sport at approx. $50 a piece along with stainless steel nuts and bolts. The base spoiler I purchased on Ebay for $60 and had them paint to match the car. I took a big chance and invested a lot of money in this project but I'm happy with the results.

I think you did a great job with the wing. Looking at the way it's attached (and given the thing itself is an "exact" replica), I bet it actually does some real work at track speeds (thinking stability in very high speed sweepers and stand-on-it breaking situations at the end of long straight, heading into a slow-speed sequence). It looks a lot like the wing on one of the Team O'Neill rally cars.

A couple images of that application:





So, to me, this wing is more functional than cosmetic (hah, rare to be able to say that) which makes me wonder about the lip/splitter. Is there any under tray to that thing or is it like the Triple R piece -- purely cosmetic? I'd be wary myself of adding downforce to the back end without something on the nose to help balance/tune the aero effects.

Thanks for sharing. I think that wing is a good option (with your attachment setup) for someone wanting to tune out any rear-end instability.

My opinion: It's not really just a spoiler as it actually sits in the relatively clean air stream just above the tail of the car, and assuming it's "flying upside down," the wing provides real downforce at speed -- not so much for a daily driver. A spoiler is usually just a device that is flush to the hood (or maybe with a bit of a vertical lip) meant to break up the trailing edge vortex (reducing drag and lift).

I've seen those and wondered if there was more going on there in the front beyond the lip. I think 2JRacing added a tray behind that attached to the radiator support. My old car had something like that done to an adapted (now out of business) RoadRaceGear.com air dam. That car was heavily modified for track usage. It has an aluminum APR Performance wing bolted to that hatch as well.

Some pictures of my old setup:







Picture when the car was basically fully done (in 2010). Sold it in 2012 as it had become unruly for driving around town (custom tune on the Powerworks SC, super stiff suspension setup, etc.).



I sometimes wish I still had the car (sold it at huge discount vs. what was spent to get it to that point), but actually prefer the Fiesta ST by a wide margin (MUCH more midrange torque which should make on-track corner exits way more fun). The SC was so linear that it just felt like a bigger NA engine (although the whine let you know it was not). It was faster, but the TQ curve was not very exciting.

You can also see that this car has a cage, etc. The Fiesta ST's interior will remain (comparatively) unmolested.

I forgot about 2Jracing's setup. You're right I'm sure there is more to it than just the carbon spiltter. I love what you did to the 2 door Focus! I would love to have a dedicated track car as well. Like you said, what is great on the track usually doesn't go well for a street car, especially a daily driver. Do you have any pics of your current set up? I'm trying to fight the urge to go beyond my current Cobb stage 3 set up and focus more on figuring out a way to put more power to the ground. I don't know... at the rate I'm modding the FiST, it might end up as just a weekend fun car. My wife would kill me though as I promise that we'll get her a Mazda 3 as a daily since her Tacoma is such a gas hog.

Car is basically stock at this point (with the exception of the MP215, a mountune "induction hose," mountune FMIC, the Borla exhaust, and a teeny tiny "M" badge). I have 15x7 TD PR 1.2 summer/drive-to-track wheels (sans rubber so far) in the garage; plus another nearly identical (save color) set on the way (will get R-compounds). Awaiting installation: Quaife, BC Racing coilovers, turbo transformer, StopTech teflon brake lines (with Carbotech XP8 pad and Castrol SRF brake fluid going on before first event), camber bolts, and Cobb poly exhaust hangers. I'm seriously contemplating a Mocal oil cooler (with a sandwich plate thermostat) and some kind of brake cooling ducting/fin. On the maybe list: a fire suppression system (basically a fire extinguisher tied to a pull cable with nozzles in the cab and engine bay) and a PCV plumbing oil catch can. Less likely: battery relocation. Wish list: Seibon vented CF hood (which, if purchased, might get painted anyway). The hood is really the only cosmetic change on the horizon, although the coilovers are likely to drop the car a bit (shooting for close to stock ride height anyway) and the oil cooler/brake ducting are likely to force removal of the fog lamps. Otherwise, it's going to look mostly stock. The aero mods are nifty at the track, but I think I'll just drive to the car's handling limitations (with the Quaife and BC coilovers in mind) and call it a day.

This time around I need to be able to drive the car in town. It's not exactly my daily driver, but the other car became impossible around town (6-point cage, racing seats, etc.). Thus, it'll keep a mild tune, a suspension that can be set to soft for street driving, stock cat, etc.

When the car is done, I'll snap some pics at a track day. Sometime in the spring.

Edit: Forgot the tow hooks. My approach probably won't be cheap.

I can really appreciate a true sleeper! The Quaife and BBK is next on the list. i can't wait to see your finished project! I'm especially interested if you're going through with the foglight delete/cooling duct as that seems to be a genuinely good way to prevent the brakes from overheating plus blow out the brake dust. I have no regrets switching to Coilovers. I currently have the ST-XTAs which have adjustable damping to soften the ride. The ride height is about .5" lower than stock as well which is great! I had to raise it because the initial setting was way too low and now my front fender wells are torn up. Also doesn't help that my wheels are 18X8

My other car had "Porsche brake fins" that worked great. Their mounting brackets were welded to the LCA. I'd prefer to do something like that, but am not sure it's possible. We'll look. The stock Fiesta ST set-back airdam might need to be modified to let air to the fins. The fins might not have a proper mounting location. etc. Here's what it looked like on the other car:
