yepp tracking shoulb be checked out every year or so, well thats what i do.

it would be creat to have a coop like nigels but we have to go bit by bit , if only parts where cheaper...hahah but i will get a perfect setup( dont now when jhahah) hope soon!!

cheers

ive been tolled by a friend that i should put a rear wing on the coop, but i dont think it would do much downforce would it? and second dont really like how wings look on the coop unless its like a DTM style wing that would probably look much better i think

Nooooooooooo!

Wings on road cars do nothing for downforce, maybe a tiny bit for fuel consumption (they reduce the vacuum to the rear of the car by upsetting the airflow)

However, they totally destroy the looks of the Coupe.

If you fit one, you WILL be ridiculed - you have been warned

don't. coupé rear looks best as it is.

Wings are for aircraft, end of!

hum i think it depends on the car!
rwd car do lay down the power with them better
on the coop it will look stupid and have little efect at all

yepp guys I agree that coops with rear wing looks like cr...
a lowered coop and 17"or 18" rims is the only think that i would do to my coop, maybe front LE lips but nothing else.

I remember clarkson talking about the difference the front splitter made to their 330d 24hr car on that Avantime article the other day. I wonder if there might be some significant gains by using one of these in conjunction with a decent diffuser?

Was it Freddan who had a rear diffuser, made by a chap at Volvo?

EDIT - Nope it was Per

Proper aero kits for production cars cost alot of money and time to perfect, although if you drive a car with additional downforce the difference is staggering.

This is a Fiat Coupe we are talking. A Car design that dates 15 years. There were no proper aero Kits back then for regular production cars. Proper aero kit on modern cars cost a lot of money because they go thru extensive Wind Tunnel testing.

What have you driven then Ruben?

jumeirah, u'd be surprised how much aero work there is on the coupe. for one thing, all the heat exchangers - rad, oil cooler, intercooler - are ducted. and this includes front splitters incorporated into the ducting design. this allows the coop to run smaller frontal openings to reduce drag and at the same time improve performance of the heat exchangers. even the latest japanese performance cars dont come with ducted heat exchangers and you pay a lot of money to fit aftermarket ducting that doesnt even work half as well as our stock design.

so pls guys, the coop doesnt need any more holes in the front, thank you very much. and if ur thinking of changing the front bumper/bodykit, make sure it doesnt obstruct the ducting. some guys have overheating problems with aftermarket front bumpers.

secondly, the coop has a front engine undertray that cleans up airflow under the front of the car. this is also matched to a working rear diffuser. yes, the 15 yr old coop has rear diffuser, something that is absent on all but the very latest japanese performance models. ever follow behind a coop and wonder why a FWD would kick up so much dust/dirt? that's the rear diffuser doing its work.

not to mention the coupe's superior shape which doesn't really need vortex generators, rear wings, etc. so don't sell the coop short aerodynamically even tho it's a 15 yr old design.

let's look at the other things the coop did 15 yrs ago which are still mainstream today - 2L high pressure turbo lump, starter button, brembo brakes, recaro seats, 6-speed gearbox, etc. there's a lot going for the coop even today. its no slouch.

Redd you have totaly diverted this thread to something else. Your emphasising on 15 years and comparing small things like start button (outdated…today mainstream is engine on/off keylesss system), Brembo brakes (its a brand not technology), recaro seats (It’s a brand again, you probably meant Recaro look), 6 speed gear box (been there for 30 years)

Talking what is mainstream in todays regular sports cars well we would have to start a diff thread for that…pract everything is diffrent,Advanced clutch systems, transmission, suspension, powerfull yet eco friendly engines, Ball Bearing & Twin Turbos, high end ICE, lighting, electronics etc..
I own my 20vt for 8 years now. Love every thing about it. Nobody has said it is slouch. We were just inputing about the handling aspect.
End of the day whether you like it or not it is no modern machine but a Modern Classic period.

cheers,
Rui

sorry i thought we were talking about aerodynamics? my apologies if i digressed on the cosmetic aspects of the car...

Chill Dude...Our Fiat Coupe rocks

With the crisis at the moment and all new car prices hiked guess we coupsters have the best deal.

Sorry to go on bout diffusors/downforce, but here's my diffusor. There are JPEG's for anyone to download for free.. Would really like to see somebody else making one too.

The Coupe was way ahead of it's time aerodynamically (with Bangle what would you expect??) and this would enhance the rear downforce (where most cars have lift, not sure about the Coupe) at high speed a little extra. See it like this; you could throw away that sack of potatoes from the trunk!

Together with the LE/Plus-kit (which gives more downforce at the front with the splitters, and keeps the flow under the car better with the skirts) this is particularly ok.

that looks nice!!

I heard a rumour that Andreas Zaptinas redesigned the rear of the Coupe, as the original Bangle design produced too much lift.

The splitter does look good BTW.

Per your diffusor look gud

Do you have any evidence to back this up? If the front splitters were actually designed with aerodynamic testing, then I could be persuaded to invest in a pair. As for side skirts, I'd be very surprised if they were designed with air flow in mind, especially some of the aftermarket jobs...

I do like some of your ideas though Per, I will definitely do get my sills painted the way you have at some point

I agree with symonh2000 as Bangle designed the coupe but was never really around to put the aero on test. Because he joined as chief of design at BMW in 1991. The Fiat Coupe only rolled into production in 94 and the 20vt in late 96.

All this talk of diffusors - I've no idea if the coupe would benefit from one or not!

However, you can see vorticies behind the coupe when driving...

Next time you find yourself on a wet, empty motorway, take a close look through the rear view mirror - you can see twin vorticies coming from out the back of the car in the spray

next time it rain ill check that out.

I for one would be up for a set, anyone else?. I'm sure we maybe able to convince per to make a few sets???. Obviously I'd be happy to pay for them.

Cheers Tim

diffusor GB. Good ideal

i would be interested to.

I wouldn't be so sure... People have been trying for years but he won't have it

Yeah I'm sorry! I just don't have the time or energy to do several sets.

Still - you can print those JPEG's out in a fitting scale.
1. Print out http://sfk.ibk.se/depa/showfile.php?carpic_no=2196&type=picture 300% size and http://sfk.ibk.se/depa/showfile.php?carpic_no=2197&type=picture 200% size.
2. Check the scale on the print, it has to match the same distance on a ruler, etc.
3. Change the print scale setting until it matches that distance on the JPEG!

Cut out, and apply to either aluminium or plastic sheets (which I used, ca 2mm thick).

4. It's a little trial/error thing, but with some persistance you'll get a good picture where they should be.

# The cutout in the bumper is 643mm wide (exactly centered).
# Distance between the middle plates (at the rears): 210mm
# Distance between the outer plates (at the rears): 650mm

See pic: http://sfk.ibk.se/forum/attachment.php?s=fd2a0b15148e7764a378dbdc2537ee80&postid=82226

Left plate can be bolted at the front with a 10mm bolt/nut thru the heatshield (as shown in pic).
Right plate must be glued (I used hot glue gun) to the tank. (Easy to remove with a hairdryer if you like)
Rest is just small steelscrews.

A little loose guide there but I hope it helps!

Right then all, As long as it's ok with per. I'm going to make some of these up. Anybody interested?

Cheers Tim
