splitter

this turned up today.

after reading a bit about splitters in conjunction with undertrays i thought i would try it to see if it makes the front end more stable? its made from plastic and its quite flexable.... so how well it will work i dont know? probably more show then go

its going to be a bit of an experiment to get it to attach so its solid but allows the undertray to be removable, it can be made to stick out quite far but then its less securely attached i need to trim my bumper so the lump in the middle fits,also depending on how far you put it foward relates to how far the ends stick out in the arch's! i may need to trim them..... it would probably work better with le lips or zenda bumper.

general idea

roughly same shape as le kit

Is this one of these?

no, its lester but thats very similar apart from it would be straight across at the front with the std bumper.

where did you get yours from Jonone ?

i got mine from here but had a bit of a nightmare getting it partly because they have updated the website which does not show the coupe stuff at the moment.

cheers for the link

Mod's like this did'nt improve front or rear stability, simply because they can not create "diffuser" type of suction. Only gain is that it looks nice, and can add a bit of extra top speed......
Best thing to do is to flat your underfloor as much as possible, smooth the shape of everything that can create drag, especially on the rear of the car.

i see what you mean as i can't find it anywhere

your be better off ringing them.

this thread is quite interesting ferrarist, people who know more than me have commented.

Yes, had a look to it, thanks....
Stock Coupe stands too high from the ground to create real downforce via pressure difference(diffuser type of downforce), and if lowered, only drag can be reduced, additional downforce will be insignificant.
And a REAL diffuser, creating real downforce and less drag must be wind tunneled before really can do it's job, and this is way too complicated for a road car.
For me, all this splitter and undertray stuff only adds good look to the car, and keeps engine bay dry and clean from all puddle things on the road.

You maybe right regarding downforce and pressure difference but as stated by per and rich( the way i understand it), even if the spitter only produces a slight amount of measured down force the "up side" is it will reduce "lift" i.e. stop the nose raising at high speed resulting in stability.
As for the undertray, having a slightly flat floor helps because it reduces pockets of air forming causing drag and lifting up the front , allowing the air to flow under the car quicker.....i believe fiat put it on the car for this reason also,.
i also think a splitter does not need to be tested to help stop "lift" as long as it is strong enough and sticks out far enough, it will help stop the front end lifting.

someone else's view not scientific mind!

Yes, interesting topic, splitter is combined with large front undertray.
Anyway, diffuser and undercar aerodynamic is very complicated science, and we can only follow few basic rules here......

This old chesnut. You have to reduce all lift before you get to downforce. A splitter regardless of size will usually cut lift to varying degrees, the one shown in this thread is very small and would only reduce lift by a small amount but at very high speeds 100+ It would have some effect, whether you'd notice anything at normal motorway speeds or on a track I'm not sure. what you can say about splitters that extend a decent amount lets say 6 inches out is they can create enough force to make true down force about that axle. Worth noting though force created about an axle line will have a leverage force making an oppsite moment at the opposite axle thus a big splitter levering the front of the car down can be lifting the rear of the car (assuming the splitter didnt create the side benefit of reducing rear lift by lowering the amount of air under the car). Anyway that real race car stuff, for a road car cutting drag is a useful thing to do especially for fuel economy - flat bottoms and reducing the air going under the car help this.

Reding the OP, if the splitter was to create a downward force in isolation (NB not overcoming the other lift forces created by the car to record a true downforce thus only a reduction in lift) consider what the force might be, say it was 30kg (It wont be you'd need a more convincing splitter for that for the speed we are talking about) then consider how strong the attachment would need to be to put up with that force if it flexes it proably wont help. Plenty of people I raced with, many with very expensive cars still had painted plywood splitters firmly attached - cheap to repair!!

thanks rich,
i realise how firmly attached the splitter needs to be, leading me to think about how firmly the bumper is attached as the force will effect the bumper fittings putting strain on them also.

on the car now, needs a bit of work as i need to get it fit with the undertray, but it looks like this, I doubt it does a lot...... but it looks nice!
another angle dangle

Thats really nice Jon and looks very factory.

i like it can i ask how much you paid for it

It was about £100, you might have trouble finding one though?

ye probs but i made one that looked the same for my old nissan primera gt le from another car

im just looking for something that makes the front bumber look abit better(imo)on the coupe. might save up and get an after market front and rear bumper

many years ago i had a delta HF turbo IE nice car but when you got to high speed it was like driving on ice so after reading yes reading a book on aerodynamics i made a MDF splitter a lot bigger than the one in the pics about 5 inches in front of the bottom part of the bumper about level with the front of the bumper lots of bolting and supports.... and what a difference to the car at high speed no more floating round the motorway it stuck to the road to the point were i could drive the car to the rev limiter in 5th and keep it there without it staining my underpants so a splitter is worth every penny you pay for it.... i know long story

its nice to hear someones real world experiences, I have read similar things on the net so it shows they really can work.

unfortunately my splitter is not big enough /strong enough to be moved forward further, so it will have less effect than yours did.

I was talking to barbz and i suggested to him to make a combined splitter and undertray out of a large sheet of alloy that extended away in front of the bumper.

It looks really good even if you think it does little in the way of aerodynamics.

I can't remember the name of the body kit that added an extra few inches to the bottom lip of the standard front bumper, I think JohnS had it on his coupe?

cada? like this?

No, it fastened to a standard coupe bumper and was just a lower lip extension that protruded a few extra inches.

Let me have a trawl and see if I can find it.

Low and behold a picture of JohnS coupe crops up in the search.




It doesn't look too dissimilar from yours looking at the picture now.

ah yes not seen that before, i thought it was a whole bumper.

Is it not called cadamuro? the auto ds bumper looks similar, maybe thats why its called CADAmuro?

It is Cadamuro, I believe its full name was front under bumper spoiler? It looks like a full front bumper on the Porto which I believe was Phils coupe because he'd had it smoothed in.

I actually bought one of these when I first bought the Vinci but decided against it and sold it to a guy near Barnsley who had a green coupe.

here is the cada front under bumper spoiler better pic this was the old L@M car

It protrudes much more than I recalled and certainly needs the side skirts to prevent it looking like Jimmy Hill with a huge chin!

I wonder if that would help with what you're trying to achieve?

I am sure it will give more downforce/stop lift but i am not sure i like the look of it and I think it will look silly on my car!
I will keep with what i have got for now.

I agree, I don't like the look either!

Would have been nice to see a picture of it showing the whole car. Looks very promising though.

From where can i get this cada front under bumper spoiler? i really like it..

Cadamuro Italian Site sells them I believe.

cheers mate!
