not ness unstable, ( i do have 155/60/13’s on the back) but at 140 i never noticed on the track but my car isent sealed for shit, with the windows up it sounded like i dident have any windows in
to get my tires hot before i went i rolled on it 3 times in 2nd gear blowing the tires off…
its stupid it really is…i thought about a bigger turbo…not right now its just dumb
once u start gettin up over 130, things start gettin interesting. you notice the wind noise alot lol
my freind took his srt4 up over 140 and it was unstable. he put the factory wing back on and it was alot more stable at that speed. so a small wing could help stable things out
