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.

JOHNRX8

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...

Elara

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.

moRotorMotor

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

topaz88

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

1.3L

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.

guy321

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

Frostee

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...

whenson417

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.

guy321

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.

PUR NRG

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.

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

Matt RX8

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.

Nubo

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?

Xyntax

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

pcimino

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.

pcimino

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.

topaz88

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.

DisneyDestroyer

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.

Nubo

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

MX6_2_RX8

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.
