Yes but how much do those cars weigh compared to plastic and CF imports from today? They are different time periods, with different materials, with different car classes.

A 1960's Mustang weighed 2,900 pounds with the Hi-Po V8.

A new Eclipse weighs 3,500 pounds.

An S2000 weighs 2,800 pounds.

A new Miata weighs 2,500 pounds.

There's no a huge amount of weight difference between a 1960's "Muscle Car" and a brand new "lightweight" roadster. Unless you're driving a Lotus Elise/Exige you're not significantly lighter.

The simple fact is that most aerodynamic aids really only come into play at about 75 mph. Of course a well-deisgned and tested spoiler will help even a FWD car aerodynamically because most street cars are NOT built to have aerodynamics for stability, they're only built to have reasonably low drag and avoid dangerous levels of instability. The overall shape of most street cars is simply not optimized to balance the car aerodynamically and if you're building a race car out of one, then a properly-engineered spoiler can definitely help, even with a FWD car.

That said, the spoilers you can buy on eBay and most factory spoilers are for visual appeal only are are not engineered to provide stability.

An example of a functional factory spoiler would be the mk1 Audi TT. Pre spoiler and >120Mph = Flippy flip flip death. Post spoiler, less death.
 
I need pics of said car to really make a judgement. Like how low and any other mods?

Edit- Oh and I'd get 2-4 for a more understated look
1 to look like a ricer.
5-6 to stand out from the crowd and draw a lot of attention.
 
Depends on where the wind is coming from as well. On the wide open road even my 3000lb vehicle felt like it was afloat and constantly pushed sideways left and right.

Most oem spoilers are built for physical appeal and less function.

I chose to go without a spoiler as it looks more clean.

Question, would placing more weight, say 50-100lb, in the trunk of the vehicle achieve similar results of having a spoiler at high speeds? My guess is no, but just want to throw this out there.

I'm not fond of the Accord, but maybe go with #2

Oh I'm quite sure that a good deal of us have one 😛. What you should say is that posting a thread about borderline ricing on a tech forum, where people would most likely prefer tuning to ricing, is not a superb idea.

no bandwagon here. just general hatred for the recent trend in rice. however, I will take a fine Japanese girl in a good tuned import. such as a Skyline. No Honda's.
but as I said, I have a general hatred for tuning imports, I'd prefer adding muscle to a muscle car. I, however, would have to learn a lot of cars before I could ever touch the engine bay of a vehicle. 🙂
 
Get a trippe decker Boeing wing to plant that non-driving axle to the ground. And you picked an accord over a bmw? HA!

I don't mind rice as long as

1) they realize their car isn't the sh!t but sure looks like it to probably everyone else.
2) they know their car isn't any faster nor was it probably fast at all
3) they also tune the car

If the car is fast but looks riced up... ehh I put up with it, because at least they put some effort into something worthwhile. But I'll take a fine Japanese girl with or without a Skyline :laugh:... although I sure do love them Skylines. Although, I'm quite sure you'd drop the "No Honda" thing if they had an S2000 or a NSX.

Just find someone who knows a decent amount about cars and learn some things from them. They're really not that hard to work on. The hardest part I ever had when working on a car was organization... it's very easy to lose things if you don't have a nice system down ( that is if you just can't leave the bolts, etc right back in the holes ).

The whole "spoilers only help RWD cars" notion is BS. It doesn't make that much of a difference whether the car is FWD or RWD, any speed above 60 is going to see a slightly more stable ride due to directed airflow. Of course, this is only if the wing is correctly sized and placed... A large wing on a small low powered car will not help, it will hinder. The same goes for a large higher powered car with a dinky little wing.

Go with something conservative, especially on that car...

BS! Shifting weight distribution toward the rear, on a FWD is not the effect you want. When you apply downward force on the rear of a FWD car, you will change the handling characteristics.......for the worst.

I don't know about you, but I prefer having all four wheels planted firmly on the pavement regardless of which pair is being driven.

Google 'fulcrum' - if you're putting force down past the rear axle, it will lift the front up (over the rear axle).

Just have someone sit on your trunk see how the car moves.

It doesn't have significant effect on the front wheel traction. The spoiler is placed a lot closer to the rear axle than the length of the wheelbase.

In any case, one of those spoilers on an Accord will look dumb.

Unless you're in 3 digit on the speedo, I actualyl doubt that it will generate any significant downforce.

If you want to sit on my trunk at track speeds, be my guest - but things get a little tail-happy. Lift-throttle oversteer = 😕

I didn't know FWD can oversteer. 😀

Not rly, but it does a pretty good impression of the "Badonkadonk" thing with the ass end wiggling and hopping around. 😛

Real oversteer is controllable, loud, irresponsible, and fun. 😀

Lift-off oversteer is common in well set up FWD chassis.
