night time...blacked out car.. I just wanna see how fast I can push it and see what mods I need.

 

you're kidding right?

 

I think there is something wrong with your front end. 150 km/hr isn't fast enough to cause those types of issues, the car was designed to run more than 50% higher than that speed and no one has noted floatiness as a trait of this car at speed. My car is perfectly solid at that speed and I'm running ap2 shocks and springs without issue on my ap1.

A bad tie rod end could do it for sure as mentioned above, or it could have a bad alignment. Spoilers and lips aren't going to cure your problem, I am pretty sure it is a mechanical issue.

 

If you really wanna learn the car take it to the track. To reduce lift and generate downforce you'll need to add a diffuser to the car essentially making the bottom of the car flat. If you want more downforce you can add canards and/or a spoiler.

 

I was kidding about the 1st part, but I do wanna to more about my car.

I'm going to get an alignment @ speedstar, hope they know what's wrong with it. Thanks

Canards (I'm sure the CR lip will act like canards right?), spoiler...I'm tempted on getting a J's spoiler locally and a spoon rear diffuser. That should do the trick, obviously after an alignment+mech check (tie rods etc as people stated above)

 

I got a question... new tires, new rims= new alignment? Should I do it now or after I get my suspension done as well? PSS9s are what I'm aiming for if my Apexi coilovers deal dont come through.
