my 406 1.8 16 v

[tonytw34]

ok here is my 406 bear with me its not finished by a long shot
ok as you can see by the last pic NO ALLOYS YET LONG STORY i got some but the buggers did not fit the front ones where rubbing on my front calipers how pissed off was i but they where only temp wheels as they are a bit scuffed but was 17" multi spoke wheels which did look nice so now i have to sell them the wheels are pictured last
any way it is chipped and has a induction kit on it and is now lowered 55mm but sitting on origanal wheels not for long beleive me
i am keeping the colour as i like the diablo red




pic 1 before



the exhaust
scorpian twin dtm



and here is it lowered i lowered it 55mm
oh and with the new spoiler which i like on it dont care what other peolpe think its what i wanted






the wheels that did not fit
if any on wants to buy them 2 of them are scuffed BUT 2 of the tyres are new and the other 2 will do another 2000 miles
looking for £150 worth it just for the tyres



oh and here is my sound system so far
sony head unit sony explod front speakers and sony 6x9's
also jbl 1000watt sub and a jbl 800 watt amp

sorry just not my cup of tea at all

Hi Tony and welcome to the 406oc,

I like the color, diablo red is so quality....

Nice and low, where did you get your springs from and have you used shortened body dampers with them, or was it just the spring kit?

Hurry up and get them wheels on chap, then re-post some pics !

[tonytw34]

the springs are spax springs 55mm drop and it was just springs i put on as i have sports shocks on it already i will get some wheels on it asap and take some new pics

Hi chap, can I ask:

What does the rear spoiler do? I have seen them on touring cars at last years BTCC but wondered what they do, I assume it is something to do with cornering or stability but not sure exactly.

Also, if you have springs fitted which are 55mm lower, don't you need to change the dampers and drop links for shorter items, and have the cars geometry set up?

How do you get on with the chip fitted, these tend to make the car run rich all the time, do you remove it for the MOT test? I suppose the induction kit and free flow exhaust counteract the rich running with an increased air flow to suit the fueling?

Set up properly, it reduces rear end lift at speed to make the car more stable, less lift = more grip. Some cars like the Skyline and Escort Cosworth are set up to actually create downforce at speed, meaning you can generate more cornering grip at higher speeds. A Formula 1 car actually produces so much downforce that at over 100mph you could drive it on the ceiling.

A Formula 1 car actually produces so much downforce that at over 100mph you could drive it on the ceiling.

So, for it to be affective you have to be travelling at high speed, say over 80MPH, around long sweeping corners.

Forgive my ignorance here, but if a road car was designed to have a large downforce spoiler on the boot should this not be complementary to other aerodynamic features of the car so that it works with them, as a package? Afterall if you found you were generating alot of downforce on the back of, say, a 406 this could be like having a loaded boot, which in my experience makes the front go light.

But how would it actually affect a FWD car knocking out not much more than 100bhp?

Agreed, hence the need for a balanced approach to aerodynamics. Generally if you want to increase front end downforce you fit a lower front apron and a splitter, which is a flat plate designed to seperate the airflow above and below the car cleanly. The lower apron makes more air flow over the car than under it, reducing the lift effects at speed. Then you would usually compliment this effect by using a rear spoiler with a more pronounced angle of attack, as just altering one end of the car and not the other could produce instability. Using a venturi plate at the bottom of the rear bumper can also help, again it cleans up the airflow leaving the underside of the car making less turbulence and therefore less drag.

It is a proven effect, my RS Turbo used to suffer from vague steering at speeds exceeding 140mph. Fitting a Laguna splitter reduced the ground effect height by about two or three inches, diverting more air over the car, making the front end much less vague at speed.

But how would it actually affect a FWD car knocking out not much more than 100bhp?

Honestly? Hardly any effect at all. Aerodynamics don't affect a car very much until speeds of about 80mph are reached, so unless you're regularly ragging the arse off it at silly speeds there's very little point other than for cosmetic reasons.

........fit a lower front apron and a splitter......

Yes, I have seen this fitted to a Citroen Saxo, a local lad was showing me. He said......''dat fing meks da car ded fast lyke a formerla wun carz''..... I was sceptical but pleased for the lad, after all his car did sound fast with the sports exhaust system fitted.

[Davva2004]

Sorry but that lad is an idiot.

EVERYONE knows the only way to make a Saxo perform like an F1 car is to add the stage 3 blue LED washer jets!

[tonytw34]

lmao any way got some wheels for my car now some wolfrace ones will post them soon when i take some pics of it

[niz406]

Cool I expect them pics on the site tomorrow !

[neildavies]

Looking smart. I'll be honest, the spoiler's not my cup of tea, but if we were all the same, then it'd be a boring place. Alloys will really set that car off though, can't wait for the new pics.

All looks well done though, credit where it's due.

[tux2006]

Looking good! not a fan of the spoiler but thats what modifying is all about different tastes you probably wouldn't like mine but thats fair enough

Where you get the springs? and do you reckon u'd get any problems with rubbing once you've fitted bigger alloys?

I have mine down 35/40mm with 18's fitted it seems to rub on the inside of the rear right wheel arch no problems with the front rubbing just the back! especailly when some chunky buggas are in the back

Let me know if you get any problems I fancy a set of those springs
