Looking for Alignment specs for the track
2004 305Z 6-speed manual Touring with 18” wheels
While getting new rear tires on Friday, I had the shop check the alignment on the car. They found that both the front and rears were both toed out at about -.15 and moved them in to factory spec of about .05.
This has drastically changed the handling of the car in a very bad way. I am starting to get a lot of understeer now at both low and high speeds. Corners I used to be able to glide around at 35mph are now tripping the VDC on the inside front tire at 28mph. On the interstate, the front feels real washy, and entrance and exit ramps are downright scary compared to what I was able to do.
I have done research after the fact and discovered that the toe-in is better for tire wear and helps keep the car straight on the highway, while toe-out tends to eat the inside edges of the tire and gives better handling going into the turns, which is exactly what I am looking for. I am really not worried about tire wear, and most of my street driving is to and from work, which is a short trip in mostly 30-45 mph streets.
On June 3, I have a SCCA Performance Driving Event and will be taking the car out to Gateway International Speedway for a day of high speed fun, and do not want to take the care there in its current condition.
I am looking for a set of alignments specs that people have found work well on the track for the 350Z with 18” wheels. I would like to get the car into the turn without losing the front end, and be able to push the car into and through the apex quickly without losing the back end. Before, I really did not have any trouble getting it into the turn, but had to measure how much throttle I gave it as I unspolled the steering wheel to keep the back in place.
If I cannot get answers here, could someone point me to a forum that might have someone able to provide performance alignment specs?
Here is how they changed the alignment:
Camber Before -.90 After -.94
Toe Before -.17 After .04
Camber Before -1.08 After -1.10
Toe Before -.14 After .05
Camber Before -1.72 After -1.75
Toe Before -.18 After .11
Camber Before -2.11 After -1.68
Toe Before -.07 After .11
Thanks for any help you can give.
