What's the fastest you've taken a 90 degree turn?
 

My 8 doesn't have DSC so I'm mainly asking for people who don't have DSC or have done this with DSC turned off. What is the fastest you've successfully made a 90 degree turn? Did the backend slide out on you? I'm tempted to try it faster, but I want to know if I try it too fast will the car flip or will the backend just slide out?

And for those with DSC, feel free to respond for a comparison to those who don't have it. :)

2 mph like all the other a-holes in fl ;) I dont know how many people will want to answer here given that Mazda likes to look on here and brand people's warranties.

I hear abbid makes these turns backwards at 75mph all the time.

31 MPH and yes, the back end did slide out! Mazda cant void a warranty just because of my driving habits. Hell, thats why people drive sports cars!

i was told that the engineers werent able to make the car rollover due to the design and low centre of gravity, so a rollover shouldnt be your worry (i dont think)

i would be more worried about an uncontrolled spin-out...

Yeah, unfortunately, they can, and they will, and have done so to at least a few people on this board. It's called unusual wear and tear. And while I don't think this would count (I've done the same, at probably very close to the same speed) just be careful what you post.

Elara is smart. She covers her own ass by saying "probably". :D It could have happened...but then again it might not have. ;)

Ok, so what have you "seen your friend" take a corner at? ;)

Depends on the radius of the turn. A sweeping 90 degree turn on a highway is a bit different than a 90 degree turn at a street corner. ;)

I'm talking about a street corner 90 degree turn.

if you do it above a certiain speed, possibly 45ish then your DSC will cut power and your car will be essentially dead for a second or two.. so I hear

they wouldnt be able to void your warranty unless they could prove it...

an internet forum post is hardly proof, you could claim that you were 'boasting' and its not actually true...

I could probably do one at 35mph but then the neighbors will look at me like I am a fool for flying through the neighborhood. Could do it even faster but I would be scared that the one time I do do it there will be a cute little kid walking down the street holding their new little puppy and I would end up smearing them both.

they can do whatever they want and it's up to you to sue them.. they can draw it out and make it very expenive for you.

it's already being done so don't think they cant screw your warranty.

Is that a street corner 90 degree turn to the left or to the right? Are the exit and entry lanes the same width, and is that width standard, narrow or wide? I assume you're talking no brakes throughout the turn and measuring either entry speed or speed at the apex.

I find a 45mph right hand turn staying within a single standard lane hard to believe. But then the guy mentioned DSC cut in so that kinda proves my point. :)

Estoque

ive never heard of a company doing that before (not saying it cant happen though)

it surprises me to hear that mazda did/does it... they dont seem like the kind of company (the mazda people ive dealt with at least) to do something like that to clients....

PS - that sux for the people it has happened to :(

word!

I think there is a lot or paranoia on this board. Mazda banning warranties is just some urban myth created by jealous Honda S2000 owners.

148 mph. I turned the car sideways, slid 8 blocks and then drove down the side street.

Mazda knows how to tell a joke, right?

I have seen 40mph on a 90 degree right turn and the tires kinda chirped for a second. This is without the DSC and TCS installed at all. Who? Oh I don't know the person's name :)

That assumes you don't hit a curb.

You might be interested in joining SCCA or NASA and doing autocross. You don't even have to join, but they give you breaks on entrance fees. Philly SCCA autocrosses run $35 nonmember, $25 member, and they always welcome beginners and even have loaner helmets (the only required safety equipment, beyond seatbelts).

There's a site myautoevents.com where you can find appropriate events by location and date and sign up.

It's a blast and you'll learn a lot about how your car really handles.

Oh yeah, almost forgot: Cornering speed is going to be dependent on all sorts of things, such as tires, suspension, road condition and material and even tire pressure. Tonight, when I go home I'll try to keep an eye on the speedo, there's a pretty flat 90 degree turn.

One thing I've noticed with the 8, the speedometer is pretty easy to read until you try to use peripheral vision, that's why analogue gauges will always be superior for performance cars.

pcimino,

Yes, I realize it's dependant on a lot of variables, I was just curious what people have gotten it to do.

I've heard of autocross before, I just don't know much about it. I'll check out your link. Thanks!

Regarding Mazda voiding my warranty: Let's assume for a minute they actually read these forums and look for warranty breakers, which I doubt they do, but let's assume. 1. They are not a governmental institution, hence don't have the authority to request IPs, user information, etc. 2. I'm not breaking any federal laws, hence they don't have the power like RIAA does to request this information. 3. Even if they could decipher who I am and where I live, there is no proof, just hearsay. 4. Court time, lawyer fees, bad publicity, blah, blah, blah to go through all of this trouble would cost way more than the cost of just paying for any warrantied repairs I probably won't even incur over the 4 years of owning my car.

With the DSC engaged, I've taken a 90 degree turn at just over 40mph, I hear a grunt in the back and keep on driving.

With the DSC off, I've taken a 90 degree turn at ~35mph and lose the back end pretty hard, but I'm able to get it back in line with only 2 lanes' worth of room.

Very true. Unfortunately, for lots of people today analog equals crappy and innacurate. They don't realize the value of second-order information.

That's probably why they made the tach analog. On the other hand there are lots of complaints that the tach is inaccurate. If it was digital I'm sure they could count coil pulses and get the right answer. I don't know what that has to do with cornering. :p

I've seen a friend of a guy that I know take a corner in an MX-6 at about 30. . . No, that was me and the warranty is gone and I don't own that car any more. I think I've whipped around a corner at about 5 with the RX-8. Maybe 6.

going about 15 mph with DSC on around a sloped 90 deg turn, punched the gas a bit and lost the back end, and totally wasn't expecting to. let's just say my heart rate shot up about 50 beats.

Well after reading this thread I thought I would give it the old college try during lunch today.

Variables:
JIC suspension
strut bars
new Falken 615's 235f/275r
DSC OFF

90 degree right hand turn onto a double wide street.

I could easily do 37-40 and stay in one lane -- 50 using the wide lane. With my stock tires I would have probably been spinning like a top.

On a side note -- I think I will have to raise my suspension a tad bit if I want to keep doing that kind of corner -- I could feel her bump the fender on the faster turns.

Without losing tire grip, I'd say 30 max. I always make it a point to never cross lanes or chirp tires when driving around public streets. 1. For safety's sake of other cars and 2. I consider it a challenge to myself to do whatever I do while keeping it within my own lane.

They do read these boards(and have been since before the car came out), and they have voided warranties ( hint: listen to Abbid). No one's trying to scare you guys, just give you a heads up. We're trying to help you out here- not going to hurt us one way or another if mazda goes after you. Don't post stuff that could even possibly be linked back to you by any stretch that could be construed as undue war and tear on the car. Just not a good idea.

I have witnessed them being entered at 40/45 and exit at 30 to 38 on stock 18's. TSC and DSC equipped with noticeable under steer, DSC not allowing rear end to come around.

People give out a lot of information about themselves over time on a Forum. Most without realizing it.

You only have 14 posts, topaz88, so the information that's been 'leaked' is slim. But I can already tell you that you have a 2005 AT w/Spoiler that you purchased in Georgia on or about the 30th of April and that you financed through Chase on a 3-year lease. With that information anyone from Mazda could easily determine what your name was and the VIN of your vehicle.

Armed with that information and a Forum post regarding some "unusual wear and tear" and a car in for a warranty repair, Mazda could easily say they're not going to cover the damage and void your warranty. They don't need "proof", we're not talking a criminal case here. They only need to have a preponderance of evidence that you "mis-used" your car and only need to convince a judge that a "reasonable person" would agree that the person posting on the Forum is indeed you.

I've found that I can enter a corner in second gear at about 25-26 and exit close to 32-34 without dsc going off.

apparrently they dont feel that way. not only do they read forums there are 7-9 people employed by mazda to read them. they look for potential problems that crop up (several tsb's are the result of them reading of a growing issue here first)and have also used information against forum members. they do it because most people dont have the money to make an issue of it. it is also no the first time an auto company has done so.

but i am on record as saying the same as you - if they tried something like that based on something i said here then there would be terrible repercussions for them as far as publicity goes. I am quite out in the open about who i am and even have my forum name as a license plate. what is said here is not "proof" of anything. but they can use it to bully people who may not have the funds to do something about it

100mph with my base 6spd, while eating a big mac and chatting on the phone.

Stayed in one lane of course!

You can't convince me that autocrossing is going to void a warranty!

It really depends on how much room you have. I was driving down a state highway at between 45 and 55 with a shoulder wide enough to park a car and turned right onto another road wide enough to fit three lanes and didn't slow down at all! A porsche or stang (whatever) with a specialized paint job was behind me. I said "hold on", (I had two kids with me, yes I know it was stupid), and just turned and the car turned. I watched the car behind me go bye with a dropped jaw, he couldn't believe it. I just signaled and turned, no decrease in speed. But I do have dsc and it may have kicked in, I don't remember. And there was plenty of shoulder so it was not a real 90 degree turn.

"A friend of mine" has done it at 50 mph. Definitely not staying in your lane though. There is a very nice section of road where you can see oncoming traffic for about 2 miles after the turn out in some farm/industrial area.

DSC on, flat skid about 1/2 the way into the oncoming lane.
