Carbon Fibre Hit or Miss

Haha kiwi I like that I really do, but if you want to bitch slap someone bitch slap Rocket as it's his fault.

I saw his handy work with some rattle cans and have to say I was impressed buddy. You can get quite decent results these days .

Worst case scenario I spend 20 quid on paint it doesn't work out, I rub them down and give them to someone who knows what there doing. But for a 20 quid chance it has to be worth a go ????

Let's be honest it's me I'm not going to pay BMW 125 quid a mirror without having a go myself first

[Blade]

Can I just say the car was filthy in those pictures so I spent 3 hours today washing and polishing it .............Not D6 standards of gleam but not far off

Cheers Rossgo always a man of good style and taste

Just remember that his favourite car is a Ford Escort Cosworth, with a whale tail spoiler

Ignore the commoners Rossgo we know what style is

[D41]

Never did get the whole 'spoiler on a front-drive car' thing?? It totally works against the intended purpose.

[Monty]

You sure about that?

[D41]

Well....if you've got a front-driver, why would you want the back end of the car pushed down?? It's just going to unload the front end.

The perils of having stepsons into the street-racing scene, I guess.....everyone thinks they know how to make the vehicle work better than the people who designed it.

D41, I'll try to be as polite as possible. As you know my background is in aircraft, so I have plenty of training and experience in aerodynamics.

Have a FULL read of this http://oppositelock.kinja.com/wings-spo ... 1665312667

If you can't be bothered which I suspect you can't, it's this basic. Regardless of the end the car drives from, the shape of the majority of cars causes a low pressure over the rear of the vehicle which increases in severity the faster you go. Even in a front wheel drive car you want your rear wheels to have the correct weight load for traction and handling. A correctly designed and sized rear wing will counter that lift from the low pressure area with down force and maintain the car with the correct weight bias over its front and rear.

There are a lot of ill designed wings, especially in amateur arenas and older factory race cars as the dynamics weren't properly understood till wind tunnels and smoke trails where utilised.

Aircraft are designed to fly. Spoilers on a vehicle are intended to prevent that from happening.
A vehicle is in contact with the road surface, has a suspension. tyres, etc.

"Even in a front wheel drive car you want your rear wheels to have the correct weight load for traction and handling". Fairly ambiguous at best....could mean anything.

Read the link he posted, it explains it for you,even a summary section at the end if you don't want to read it all.

[quote="It's a "Porch-uh""]To summarize:

Both wings and spoilers reduce up-lift at the tail of the vehicle, but use different mechanisms.

Wings are airfoils designed to directly deflect air upwards and thus push the rear of the vehicle down. They generally add quite a bit of drag.

Spoilers are barricades to undesirable flows, and thus are able to reshape airflow streams around the vehicle. This can help keep the rear of the vehicle down and decrease drag by changing the effective vehicle shape.

You need computational fluid dynamics and/or wind tunnel testing to quantify spoiler/wing performance.

Neither have any positive impact whatsoever on straight-line low-speed acceleration. Both are primarily intended to improve stability and cornering at high speeds.

Got it? Good. I'm tired of the internet being so consistently wrong about this.[/quote]

Thanks Reaper

And D41, the fact you are calling it a wing then a spoiler shows you don't understand the basics. They are completely different devices regards of general public interchanging their names incorrectly. A wing produces lift (up or down dependant on orientation) by reaction forces where a spoiler destroys lift and increases drag by impulse/impingement forces.

And for the record I knew you wouldn't read the article. Why be educated when you can rant with little knowledge.

You are but the pupil.

[D41]

I did read it before I posted.

Although I don't know why you posted it either if you suspected I wouldn't??

But I did. Sorry. I promise not to read it anymore.

Your comments lead me to believe you hadn't, as has been the situation in the past.

If you did read it do you now understand and agree a wing (not a spoiler) is useful on a performance front wheel drive? and correctly fitted and designed it won't cause the front to unload as you claimed?

[D41]

No, I don't understand it.

I should be thrashed.

[Kwacky]

So yeah, silver for me...............

[D6]

I'd like D41 thrashed too.

Oh is that not the Poll?

[Monty]

Silver what?

[Blade]

I m going to get a carbon wrapped Alfa with a front wing and rear spoiler

[Monty]

with silver mirrors?

[Blade]

Can't decide tbh. I need to start a pole to get some opinions.
