Impact of removing spoiler

So two questions:

What is the impact on handling of removing the rear spoiler on an Evo VII. Mainly day-to-day driving, a few blasts here and there and maybe 6x300mile (x2) motorway trips a year? (at times topping 120 mph)

Also, what impact on handling would having lowering springs (eibach) on the front (bilstein B6) and standard springs (std shocks) on the rear?

Thanks

Well it generates a lot of downforce at evo speeds so it will affect it

What are you doing 120mph on the road for would be my first question? I wouldn't do that sustained on a motorway with other people on the road in ANY car.

Had mine up to nearly 150mph on a test track for nearly 8 miles with no-one else to hit and the concentration required was knackering!

Plus you have a GT-A which IF and when it all goes south all you have is brakes because the Auto box won't let you shift down at too high a speed for the revs if you REALLY needed to and give you engine braking. I know I've driven one.

I wouldn't have "mix and match" suspension components either.

(sorry but you did ask)

You'll need to be going pretty fast to start noticing a difference. A corner that you could take at 120 with the spoiler you'll only be able to take at 115.

If you don't know what you're doing, just leave the car alone.

Not really, it's more of a spoiler than a wing.

I must question thine sanity , rich coming from me
Going for the hunkered down front end look ? And we know of thine fondness of spoilerless boot .....i reckon it would be fine , but id just say that contemplating you meeting a fiery death
120kph you meant i know
Go forth and delve i say ( those Blitz suspenders not a viable keep ?? )
much digression ...

Mitsubishi invested £millions developing a stable platform and you want to undo all that R&D.

Leave the rear wing in place and if you are going to modify the suspension then do both ends.

Seems to be more and more complete tools owning Evos these days.

Wow, so much negativity. Fair play to you all.

It never ceases to amaze me that a person cannot simply ask a question without being labelled a "tool" or being told to step away from Evo ownership - to which I say fŻÁk you both.

Also fully aware Mitsubishi invested millions in r&d on the Evo platform - for rallying.

It's unlikely a spoiler like those found on Evos will create much in the way of downforce, but you will likely see more lift at high speed without one.
On top of that, a spoiler will normally improve airflow and drag coefficient, so mpg and high speed performance will be better with one.

This is all generally speaking however, I've never really seen air flow performance specific to Evos

Some interesting responses

WRT only lowering the front, would I be right to assume this is because of the front looking higher than the rear? If so, that's how it's meant to be- look at the skirts in relation the ground and you'll see that they're level. I believe someone quoted that the front should be at least 5mm higher (measured centre of wheel to arch lip) but ideally between 10 and 20mm for optimal front to rear balance as ride height(s) is a common issue when installing coilovers.

Mixing and matching springs isn't a good idea IMO. If you want to play with heights get coilovers and adjust away.

If you do lower it would be wise to have a 4 wheel alignment done. Also when refitting the fronts, be aware there are camber bolts that hold the shock to the wheel upright/ hub- make sure they're fitted the same on both sides.

As for the spoiler, one way to find out. If you want it off, take it off. But be aware at higher speeds it may cause problems.

It's your car so do what you want- and if you do it wrong there will likely be an expensive lesson learnt

I don't think removing the spoiler will spit you off the road bud, but your suspension suggestions will depending on how you drive it

Mitsubishi developed the E7 and it's suspension and aerodynamics for road and track use.

If you mess around with either without knowing what you're doing, you risk making the car slower and dangerous to drive.
