hey so i track my car and i want to see what kind of body kits or what bumpers and stuff i could get that are nice + work. Any bumpers with a front splitter or canards or something like that? who makes diffusers or what. lookin for something nice. sorry its kind of late

 

The RX7 body was designed very well. The only reason you'd get a body kit for the RX7 is for looks, or if you needed to feed more air to the intercooler.

 

Or if you want to fit much bigger wheels....

 

or if you want better aero.

add a front splitter and rear diffuser and a nice gt wing and you will have huge improvements with aero grip

 

You should PM Chaotic FC

 

Canards can be fitted onto anything though. Diffusers - same thing.

Depending on how much you track your car, and what you're looking to gain - there's probably other ways to achieve the result.

 

Agreed

 

Vey, very few kit on the market have actually any ''areo'' benefits. It takes millions to do actual wind tunnel testing and most sport car have already undergone such testing from the factory.

If you want a kit that as some usefulness you will have to look at the big buck racing kits. RE-amemiya, AWR and the likes.

 

R-magic in japan they make aero for time attack fc3s

i think you will be happier by adding under diffusers to the stock body, rather than optioning for functional aero kits.

Everyone above has made very good points as far as gains for a track car.

What kind of racing does this vehicle enter in? or what kinda racing will the car enter in?

 

Here the kit setup I used. Gp sport front bumper and shine rear diffuser.

 

^
I am soooo doing the rear diffuser now.

What side skirts you running?

 

That is shines r-magic side skirts.
Thanks Robert

 

alot of guys in japan run kits simular to GP

and the RE kit



Supernow is probably one of the more recently popular tuners who is kicking *** right now..

I like the kits!!!!

 

I'm the one which bought the AIT bumper off you a while ago. Still just bumper. The rear looks sooo naked

 

I love how everyone looks to the japanese when it comes to cars and what they do. Assuming of course there are no idiots, shadetree mechanics, or ricers in japan. Saying, "ohhhhh - look at what the japanese are doing," in reality, has zero relevance. I got news for ya, there are shady trees on that side of the pacific too.

 

Unless you're running your car VERY low, have a smooth underbody, a good front spoiler and splitter and so on, a diffuser won't do much good at all. What's probably worth more time is if you cut away the lower part of the bumper to let the air out more easily to reduce the parachute effect.

Just because a part is used on a "time attack" car, doesn't automatically make it good. Most body kits are probably worse than stock for drag, maybe for lift too.

About the only thing I'd EVER count on ANY kit being better at is getting more air to the radiator, oil cooler(s), intercooler and so on. Most kits would do better without the side openings, or with a fairly small opening there for brake ducts. That is unless you do a custom dual oil cooler setup with them mounted on the sides to free up air for the radiator and intercooler (if applicable of course). On an NA, it's probably best to have the oil cooler in the middle and keep the sides small or non-existant. Openings in the front of the car are very bad for drag.

 

say whats the brand of that big tail wing? makes me what to get one of those

 

Not everything from Japan is "rice".. the ones I have posted are based around style and function... So whats wrong with looking at how these cars are being tuned in their native land? compared to whats going on in the US, its nice to look at those over their. The cars typically look different. more aggressive suspension and body mods than typically found on a US fc.

Provided those aftermarket companys wont spend the money to wind tunnel test their kits, hell no one would, the fc market is dead imo, bodykits get knocked off and copied left and right. Its not hard to test out what you like and see if it works out for you.

Tuning and styling of the Orient has always looked different, but it works over there. Big wheels low profile tires, stiff coilovers lowered cars, aero, spoilers, bolt in cages, bolt in performance parts+upgrades. Style + Performance together, and the parts selection aren't typically cheap. Might not be the "ideal" as some think. It all comes down to it being your car and doing whatever you want. The way you tune and modify it expresses your style.

 

My opinion of it is this, if you want style and function you'll probably end up paying a lot more. The higher end kits have a higher chance of actually being somewhat tested and working. With that said, knock offs, if made of good quality, I would imagine would provide some function. From the looks of the kits it seems like its more for getting air to intercoolers and such.

But then again I am talking out my butt on this one. If I were you I'd just get a kit that you like lol.

 

try origin .com

 

from my track experience... I have found tires to be the best MOD.

Aero wont help in at a track unless your doing atleast 70+mph in the corners. Still wont make to much diff.

I say Your best bet for track results is. WIDER tires and better rubber. ANd a good alignment

Don't discount what aero can do for you, but don't assume that a body kit will give you better aero.

By using a wing you can set the car up to have better handling at all speeds by setting up the suspension to be tail happy at low speeds and using the wing to calm it down at higher speeds. A simple air dam and splitter/undertray can add a bunch of front end downforce and a properly vented hood ducted to the radiator can add to that front end downforce as well. Vents in the rear portions of the fenders can help evacuate the air, reducing the high pressure stagnant air in there, reducing drag. Having the fenders fully cover the wider tires as viewed from the front will help reduce drag (note: most widebodies DON'T do this). A smooth underfloor can reduce drag as well and sideskirts can help reduce in-leakage to help generate underbody downforce. A diffuser, when combined with an airdam/splitter, proper sideskirts and a smooth floor can really help the underbody develop downforce, but it is only one piece of the puzzle. A diffuser alone will add little to no downforce and will not do much if anything good for drag. If you fully cover the underbody, you will almost certainly need to add coolers to the transmission and diff and will probably need to let some air flow in and out to cool the exhaust.

A well designed, tested full aero package can take seconds off a lap.
