2013 gt500 wobble

[Shelbanator]

so just recently was out for a drive, seeing it was such a nice day i decided to pick it up to 145mph my car decides to start wobbling very drastically so i let off the gas thought maybe it was the road, so i did it again on a well paved road and still wobbled like crazy any ideas on what this might be? Can tires cause such a drastic wobble ?

Did it feel like it was in the steering wheel/front of the car, or in the seat of your pants/rear of the car?

Did you seriously admit to going 145 mph on a public road?

Oh brother.


OP, answer the first question, not this one.

 

[03Sssnake]

Could possibly be tire/balance issue. Would check tire pressures, then have tire balance checked. If that doesn't resolve it, then it could be a suspension problem, blown bushing in front control arms, blown shock/strut etc...

I don't recycle.

What tire are you running? I kind of remember this being an issue a few years ago with several 13/14 owners. You might want to post in the 13/14 section.

Is it a "wobble" or more like floating? Once you get up to speed, do you get on the brakes fairly strong?

It felt like the wobble was from the rear end

That's your problem for sure I have the same tires and got the wobble real bad. Bought some 17x10 weld's mounted on MT et street r's for the rear and the wobble was completely gone. I'm still running stock wheels and mpss tires up front and haven't had a single problem after changing wheels and tires on the rear. Lots of people have had issues with those tires they are garbage and dangerous.

Ive been wanting to buy some of those wheels ,what is the tire size your running? Stock height?

 

[04whitesvtlight]

315x35x17 I'm lowered and they haven't rubbed at all. They hook great on the street not that great at the track.

How are MPSS tires garbage and dangerous? I only know 100 people that exclusively run these tires. Tracks days and DD. Zero issues running over 155mph, etc.
