Floating feeling
For a while now I feel like I am floating alot through corners and it doesn't feel as precise as it once did or I am too used to how it feels and its not stiff enough.
Even when I am driving 60km(normal road speed limit) i can feel the car move about in my lane and always correcting where it is moving around. What would be the cause of this? I've have done 8000kms on the car and it is completely stock heaps of rubber left. I did have a puncture in my rear right tyre this as been fixed and it still feels floaty. I am not sure if I need new rubber or new suspension. What do you recommend? |
Did you check the air in all four tires?

so tyre pressures where fine all above 40 psi...
Which i was a little wierd since the plack on the door says 35psi... what should it be? |
What do you mean by floating feeling?
How large are the movements? and how are you correcting them? With a well tuned car suspension you will get some movement in the corners, part of this is perceptual, and part is real. The Perceptual part is that most turns in the real world have a bit of variation to them, rarely will you have any that run a perfect arc. You are also sitting much closer to the road and as you gain awareness of the vehicle you will notice movement that you didn't in say a pick-up truck (even if the movements are the same). Real movements result from a couple of factors. One of these is how you drive, in these cars even minor differences in power application can result in some movement, as well as how smoothly you turn in and exit the turn. Another thing that can cause real movement of the vehicle is the road surface; bumps, divots, and undulations all cause a vehicle to move. You are also at the mileage (kilometerage?) where stuff is broken in allowing it to move easier. Of course it could also be plenty of things out of whack as well, like your alignment, differing tire pressures, loose ball joints or rod ends, loose suspension pieces, loose nut behind the wheel, etc... |
cold around 34-35, warm 38-40, starts to fall off around 44

Happy to admit I am not the best of drivers and i might take the wrong line more often then not, but when turning i always aim for a smooth wheel motion not jaring motions. Alignments should be okay after the repairs tyre. Might have to get under the car and poke around for lose things as I did notice it after they "replaced my trans oil". What is around that area that could cause this effect? Might also book it in for its first service. |

The car is definitly very sensitive as far as steering goes, any little movement will results in a change of direction. If you get an alignment with more toe-in I think it might help as it makes the car more prone to head up straight ahead. Somebody might want to chime in about it...

The place to start is tread wear, and alignment, and a good inspection of all the suspension and steering mounting points. |

you wont have an issue with bump steering affecting the right and left wheels differently thus having every single bump force your car to change direction at different rates. :slap: |
IMO everyone should get the OEM camber bolts and have the car aligned once they get the car. Makes a huge difference and those bolts are dirt cheap. I don't trust factory alignments anyway.
I'm not convinced that's the problem here though...I think the FR-S is just really soft up front and the chassis moves around a bit. Super soft springs and squishy bushings. - Andrew |

Try rotating the tires. It is simple, free, and you would be surprised how much of a pattern your tires could have adopted in a short while. Ground Control |

unequal toe also affects how a car behaves in a turn, and how it turns. Toe is not static throughout a vehicles steering arc. Unequal toe also affects how a car behaves when it hits a bump. As these are cars with a steering rack, unequal toe results from the tie rods being unequal length, which will result in slightly different bump steer (yes the car has bump steer, and no, you can not ever get rid of it) characteristics. Though honestly the change will likely be so subtle not many would even notice it. |
I just posted in the BRZ section about the steering feeling loose and wondering if thats normal after some break-in. But reading your description it does sound like a floating feeling. The steering just moves so much easier then before. One week everything was great the next I was wondering what is with my steering.
I do a good 30-40minute drive on the turnpike every day to work. Straight line going 80 and constantly feel like i'am adjusting for movement the car is doing like it was windy outside pushing the car around a little. The resistance the steering had the last couple months just disappeared. Even shifting just casually was no issue before sometimes will pull the car to one side now. I've owned the Car since August 1st and has 3200 miles on it. All stock car and just had to put air in the tires today my back driver side tire was very low while the rest were fine. |

That is perfect to what it is like. :S |

And do you have the part number for that camber bolt again? Is it actually recommended by Subaru to use for that reason? Thanks. |

I'm at home (thanks hurricane sandy) so I don't have the part number for the OEM camber bolts but it's posted somewhere on the forums. We can get them for you if you need them and can bundle them with our RCE springs. I'm honestly not sure why Subaru/Scion didn't make them standard. There really aren't any drawbacks to them. - Andrew |
I have noticed that my steering is getting a lot loser.
As I can move the wheel <---&---> more before i can feel turn in... how do i fix this!? |
It could be tires, or alignment, or loose parts. My bet would be the alignment.
|
Did you ever figure out what the problem was?

Dump Prius tires

Strange feeling that maybe I'll get used to, but reading all the reviews about how balanced the car is, and planted, I was beginning to think something was wrong. I've also got the little bit of play in the steering wheel before the car actually moves left to right (as in I can do a little left right left right jerk to the steering wheel a few degrees, and the car will stay straight). Strange indeed. |
Problem with the steering rack bushing perhaps?

[/QUOTE] Why are you jerking the wheel left to right? Think about that real hard then realize that it's a good thing that the car is compensating for your silliness by not actually doing what you want to do. |

After 10k miles in 3 months of driving with approximately 16 track days, the car does float over certain corners. This car was built with sports in mind but it is extremely comfortable for what it is. Making sure cold tire pressure is at manufacture specs with proper alignment is nice, but I highly doubt you knocked your alignment out from just driving around town. That is, unless, you smacked your suspension into something.
Are you on stock suspension? All in all, I think you may have just gotten used to the ride quality of the car. Drive the car hard enough and you'll forget about it. |
I just had this after i put my stock wheels back on but forgot what tyre went where.. maybe its uneven wear on the tyres..
i was getting blown around on the freeway.. was very weird. |
My vote is on squishy bushings. I noticed this just a few weeks after I got my car. The really firm feeling was mostly gone. Yes, it could have just been getting used to the car, but I have driven a lot of cars and I think that it is not just my feelings. At least the bushings is the point I have chosen to attack to solve this problem. Something like these (although I may go with the offset ones):
http://www.perrinperformance.com/brz...esponse-system as well as other stiffer suspension and drivetrain bushings and braces. Just part of my upgrade program. This car is silly cheap for what it is, so it is necessary to expect to have to upgrade a few pieces. Also, it is brand new to the market, so Toyota and Subaru have no long term experience with the car. I'm sure there will be some changes to new production models in the future as they learn about customer's experiences. It was built for the masses, so if you want tighter long-term performance, you will likely need to go aftermarket. |
ill just wear down my stock tyres and see how it goes. i had no problem when i was on my other wheels.
|
Yeah still havne't figured out what the issue is.
I've had it aligned and I havn't notice a change. My brother had a drive of the car also and he pulled over because he though one of the wheels were lose just by how much it was moving around on him on the highway in a straight line :s Going to the dealership on Wed. |
find someone else with an 86 and drive them back to back? see how they compare on the same road

COuld it be the deadspot in the steering?
Think most electrically assisted steering have deadspots some larger than others. If there is a fuse for the steering, try pulling it and going for a short drive. |

I noticed mine moving about at speed the day after I got it but it was only on one stretch of road which I haven't been on since. I suspect the stock tyres are an insult to this car, they start complaining way before you expect them too. I'm tempted to replace them with 225 or 235/45-17 on the stock rims, which I like more in real life than I did in the pics. Perhaps something like Bridgestone Potenza RE-11? |
I'm willing to bet your rear toe is OUT! Get a Complete alignment.
|
i'm having this exact same problem too, feels like it's SUPER windy outside when i'm going down the highway. floaty and tons of corrections just to keep going straight.
i just assumed the winter tires i put on the car were really squirmy, i never drove the car on the stock Primacys. |
