Been having this issue for a long time.
Car will not track straight when I let go of the steering wheel, it feels like it always wants to pull to one side almost immediately, also sometimes more pronounced when I hit the brakes.
Cannot do hard launches because it almost instantly wants to fly into another direction off the line! Even with only a small amount of hard throttle it can feel like it wants to do that.
This problem only seems to happen randomly, some days the car feel like it will travel straight at cruise speeds and launch straight, some days I have no hope at all.
I have had 2 alighnments done from 2 different alignments centre in the past 6 months. The 2nd one they also installed brand new MCA street Ultimate coilover and set the softest setting on the back before they did the alignment. After I picked the car up from them, everything felt perfect and stable, but only for a few hours of driving which after it went back to crap again. They said they will look at the car again next week.
Just trying to get any opinions if anyone knows what the hell is going on before I take the car back to them.
Could it be something to do with any of my parts not functioning well?
I have added these parts all at the same time:
Z1 urethane motor and trans mounts
Whiteline diff bushin kit
Quaife LSD
Z1 Premium SS brake lines
Could it be that a long time ago my aggressive offset Meister S13P wheels on the front 19x9.5 +17 scraped the Akebono calipers for a little while, could that have done some damage to cause my current issue? Brakes pushing the wheel or something?
I have uploaded the latest alignment sheet.
