JJ - PNphpBB2 implementation

We started talking about this in another thread earlier, but I've got a little point to make.

It seems to be pretty universal that the EVO has the harsher suspension of the two, right? People have commented on it lack of body roll and so on, right?

WTF is this?????



That looks like a butt load of body roll to me!!!!

Is it just me or is the back left tire off the ground. It is more than body roll, it is just to the point of rolling over entirely. Just kidding. It does look like more roll than everyone has claimed.

Well you see this EVO also has the sunroof which raises the center of gravity causing the added body roll. :p

Hmm yeah I think there is some body roll there.

I believe from the text that accompanied the photo at evolutionm.net, this car was being driven quite aggresively. Here's a picture I took of an Evo at the local test and tune, being taken around by someone else to let the driver get a feel for what his car can do:



Not the sharpest picture, but it will do. I'm sure the car had a lot more in it, but the driver doesn't normally drive AWD cars. He's awfully good in just about everything though. Hopefully one will show up at an autocross and I'll be able to watch it while working a corner. I'm sure it has more roll than a Z06, for instance, but probably less than many other cars.

Re: add-ons

Maybe it's just me, but I don't want any of my wheels thinking of leaving the ground at an autocross or during "spirited" driving...

I was told that I got my Miata with stock suspension and swaybars (absolutely stock, with (relatively) lots of body roll) to lift a wheel. That was pretty cool. We have a 911 in our region that lifts a front all the time, and a VW that lifts the inside rear all the time. It's not that uncommon. If you watch the rotor spin closely you can see that a lot of cars have lifted a wheel enough that it mostly stops spinning. In some you can see lots of pavement below.

Now the station wagon that lifted the inside front and rear in a corner -- that is bad. I'm still kicking myself for not getting a picture of it. For some reason the driver refused to do it again so I could get some good photos. :) I was clear that I wanted two wheels -- not door or roof.

Yeah I had a friend that I used to go with to autoxing sessions... he had some kind of hatchback hyundia that he could easily get on 2 wheels. He had to be careful. The thing was completely stock, other than tires. He always placed in the top 3 cause there were usually only 2 or 3 people in his class.

...and this makes the then worry what the sti will do if it has the "lesser" suspension? body roll blows and we might have more. :(

Body roll is when the car leans in a hard corner, like in the pic. Understeer is when it does not turn enough and kind of plows straight even when you turn the wheel to turn. Like trying to turn on ice but the car keeps going straight.

Lifting an inside wheel is common on FWD cars and is a sign of a chassis with minimal flex and some suspension travel. With AWD it is not preferred (obviously) but happens under extremely aggressive turn in.

The WRX has considerable body roll compared with other performance cars because of the suspension travel designed to lessen impacts on gravel rally stages. This however does not doom the handling (as we all know the WRX handles damn well with its considerable roll). This is because the suspension geometry is engineered to maintain good tire contact patch with the road through the limits of suspension compression and droop resulting in a car that rolls, but still sticks the corners.
Since the STi is setup for tarmac, the body roll should be less than the WRX, the suspension travel is less and handling will be improved. The basic geometry is the same as the WRX (as far as I know), so the improved springs/struts, bushings bars, etc will make all the difference.

The body roll in those EVO pics is NOT very significant for a factory stock car (especially a rally car which has to tolerate rough surfaces)

All very well said.....but for a car that people are saying it beating kidneys and is hard-core.....it sure doesn't look that way. I consider the suspension I have to be at the edge of the comfort-sport line, and it has no where near that amount of body roll.

My only concern is that what people (mag editors specifically) still call "stiff factory suspension" is stiff when considered only by the general population and car journalists that split time between Cadillacs and Foci, not those of us that race/tune our vehicles.
