My 09 R3 has a pull to the left. I've personally aligned this car 3 times trying to get my setup how I want. All readings are within spec but still it pulls to the left. I.E. Hold steering wheel straight. Vehicle drives straight. Let go of steering wheel, vehicle starts moving to the left. If I remember correctly the vehicle will pull to the side with the least amount of caster. Both caster reading are exactly the same. Also is there a re calibration of the eps to reset center point? Maybe the eps zero calibration is set to the left slightly and is constantly assisting to center? any help will be appreciated. Thanks.

 

Have somebody else do the alignment and report the results back.

 

Id prefer to do the alignment myself. Maybe the machine i was using was not calibrated. The hunter machine at my work doesn't have big enough adapters for 18" wheels. So I had to use another dealers machine. Perhaps I can swap my 17"s off my Acura and use the known goods machine. But there is no calibration for the steering angle / eps for after an alignment?

 

Cross rotate the front tires, see if your car pulls left.. If the pull switch sides, there is something up with one of the tires.

 

I thought that too. I just put new tires on the 19"s. Zero miles. I swapped them on Wednesday
and still no change. I really hope that something isn't bent. I wanna do another alignment with my 17"s so i can use the machine at work. I'll repost once I get around to that.

 

Does it do it on both the left and right side of a highway? The RX8 seems more sensitive to road camber than some cars.

 

road crown does not affect the pull. even though the roads suck here lol. I hope to have an alignment done by next week.

 

Rear alignment? Air Pressures?

 

If your alignment machine is of the vintage that it's heads cannot clamp any wheels beyond 17", I wouldn't put much stock in anything it has to say. Are you jacking up or doing a rolling compensation? You know you cannot do a jacking compensation on a car with multi-link suspension, right?

 

Yeah the machine I used was the hunter with clamp on adapters. It uses the laser mirrors/pickups. I do roll compensation and caster sweep. The machine I used I don't use on a regular basis since it's at another dealership of the same owner. Once I get my hub rings, I'm gonna swap my 17"s on and try at my dealerships machine which is also a hunter but much newer. Same style though.

 

Post your alignment specs.

The car will pull to the side with....

the most positive camber.
the least caster.

To get a car to pull left you usually have to have a decent cross between sides.

Or it could be related to tires, I've seen brand new tires cause a pull.
