Car Shakes crazily when over 150mph.

[L1ONE]

I bought a Ferrari 458 Italia '09 and done some modifications to it.

After a few races it starts to shake like mad when going over 150mph like it's about to take off from the ground. It gets uncontrollable over 180.

Any tips for this?

Increase downforce on the front and rear spoilers?

put a wing on it and add downforce. When too much air gets under the car it wants to lift it and causes it to be unstable. A good wing, front lip and side spoilers will put that car super stable. You will loose a bit of top end speed and acceleration up to due to all the downforce, but you will have great grip and high speed stability.

Aero spoilers available in GT Shop (where you get the oil changed).

My ZZII had a high speed wobble until I purchased a spoiler. Wasn't as bad as yours sounds though.

Have you ever driven a real car over 150mph? Even in a fairly modern, comfortable sports car (my experience is in a 2002 M3), it gets pretty rough.

Did you purchase the 20k chassis ridgity (spelling lol) cause that should help in the high speed turns and I'm assuming high straightline speeds

Anybody have the latest Viper coupe ACR? It comes stock with an aero package that's good for 1000lbs of downforce at 150mph so I was curious how stable that car feels.

That's weird I bought mine and did mild mods without a wing and mine has never shook. I would put money on the chassis rebuild, he probably hit a wall to many times.

What camera view are you using? The cockpit view shakes like no other at higher speeds. (especially in corners) The Bumper cam shakes a lot less but it still shakes a bunch. The roof cam shakes very little (if any) and the third person cam doesn't shake at all (but I never use it).

The camera may have something to do with it but adjusting performance parts like suspension and such is a good idea too.

I have it, that thing is glued to the road. I have it fully modded now and it still hugs the road like crazy even though it has nearly 1000 HP and crazy torque.
