Scary rear end feeling at high speeds!
 

Ok so i have A 2014 brz that i took to get an alignment after an acident they got the car within specs they said but whenever i exit a freeway offramp the rear end wants to slide in a violent fashion. We checked the rear end everyrhing seems solid and not loose.
The only thing that is not within specs even with a camber bolt they installed on the driver side front wheel is the front caster which is at 4.24 degrees. Any ideas?

This is interesting, I actually had the same exact issue, but it completely stopped once I got my 18x9.5 wheels and tires... Some of the things that could cause it are imbalanced wheels, bad tires, or cross threaded wheel studs, ALL of which I dealt with at once. Never take your car to cheap shops like Firestone or Midas. Anyways, I would check for these things first, if nothing in the rear is loose. I had that same frustration for weeks and it would be even worse in the rain, I would give my car 50% throttle in the rain in second gear and the TCS lights would come on! Very sketchy...

Check if your rims are bent. That happened to me when I smashed into a curb drifting. I thought the rim was ok, until I drove on the highway and the back end kept wanting to slide out.

Check your toe arms too, make sure they’re straight and not bent.

Just noticed the front and rear tire rotation arrow is off could this cause that

Yes, I believe if your tires are directional you can have some pulling happen on one end

Its my fronts that are not in the right direction not rears

Should definitely fix that, but I think your rear alignment specs could also be messed up, more specifically your toe in/out... not too sure what else it could be

Are all four of your tires directional ..??

Yep, like said, get them all spinning in the right direction for starters.

Besides the wrong direction tires what are the alignment specs?

I made them all directional and i swapped the fronts to the rears to rule out the rims but its still happening. Ive been trying to post a pic of the alignment print out but the size is too big
I can send the pic to someone maybe theyll have a better shot uploading it?

Send it to me via message if you can

Are you tires good? Size and condition?

most likely rear alignment, that is a textbook description for what it would be like to have a misaligned rear.

Get this car aligned somewhere else.

Directional Tires facing the wrong direction will give you the most issue in bad weather conditions.

Weirdly enough, I had a good alignment on the rear and still had these problems. It turned out to be I just bought some bad tires.
