My stock suspension 2003 has a lot of lightness in the front at speeds of 80+ ( i have not driven other evos, so i dont know what is normal)
I have the stock undetray.
I dont have unlimited funds so i am trying to decide on the best bang for the buck.

I dont think a front lip will be as effective as a Beatrush undertray for down force, or maybe some lowering springs?

What are your thoughts between those three peices?

 

I can't say that I've experienced what you are talking about in any evo... what suspension mods and bumper are you running?

 

Undertray, front wind splitter helps a ton (says topgear). And coil overs or good shock/spring setup should help. My A4 felt that way with blown struts at high speeds.

 

Front wind splitter could reduce MPG but you have unlimited funds =p

 

How many miles are on the car? Mine is tight with no lightness at all.

 

Hmm.. That's not normal. Even when it was stock I never had any "lightness" at speed. Even at top of 5th gear. :}

 

I would be looking at other issues, instead of trying to increase downforce with a splitter or front lip. I certainly have not felt this in my Evo.

 

I dont even run an undertray and i dont feel lightness in the front of the car

 

u might want to check your suspension and see if everything is tight. especially the ball joints. even on stock suspension u shouldnt feel any lightness, thats odd.
i've felt this before because of a loose ball joint so the hub was lifting freely over bumps or high speeds.

 

Splitter. Make one from alumalite.

 

I dont want to make it sound like its light as a feather, but it definitely does not stick more with higher speeds. I guess i am asking about whats the best thing to improve front down force.

Its a stock suspension with 70k miles.

 

i have a set of canards for sale.. that will help almost as much as a splitter for a fraction of the price. PM if interested

 

If I were the OP... I would inspect all my stock bushings to make sure they were still good and replace any worn ones with the whiteline urethane replacements. After that, see if it's still "light". If it is, then I would grab a set of swift springs. They will give you better handling and lower the car a bit. The lower stance will give you less turbulence under the car and therefore more grip at high speed.

The canards would help alleviate the problem... but what if there is something else wrong with the suspension in the first place?

 

inspect the suspension first. don't start adding bandaids to patch up a problem that's being caused by something else. you shouldn't be feeling the front end getting light at any speeds really unless your shocks are going bad, or you have something loose up front.

adding a splitter will affect the car a lot more than you might think. a splitter should be added if you're planning on racing the car and it should be apart of a larger plan on a way to set the car up. just adding a splitter to fix a lightness issue isn't a good idea at all.

 

Canards will help, but no where near the amount that a properly implemented splitter will.
