Hello everyone,

I’ve purchased 2020 Ftype P300 RWD Convertible recently. I have been experiencing weird issue for the past few week.


Front of the car feels like sliding if I over a small bump while cornering above 50KM/h.

I can reproduce it easily when I am cornering and there is a small imperfection on the road.


Car is definitely not sliding but it feels like it is.

Car is equipped with continental summer tires

• Front tire 245/45 R / 18 W
• Rear tire 275/40 R / 18W

Cars computer indicates that pressure is at 38psi (when it’s cold)





Wloukld that be related to suspension / control arms or bushings? Car is fairly new. I have 12k on the clock.

 

How much tread left on the tires? I have no idea how the F-Type performs on 18" wheels, but the P300 is the lightest F-Type at the front..

 

Scuttle shake?

 

This sounds like to me normal tire behavior. When you hit a bump, you're altering the traction characteristics of the tire. This could be due to sidewall deflection or that split second that wheel loses traction and also interrupting the weight transfer of the car. Not to state the obvious but I'm assuming it doesn't do that on a non bumpy turn?

 

Check the camber of the tires. Jaguar uses aggressive camber to enhance cornering but it causes the tires to wear prematurely. The prior owner may have corrected this, which would degrade the handling of the car. The car also could be out of alignment. Also, this aggressive camber caused wear on the inside of the tires and your tires may need to be replaced as well. Also, as others have pointed out, going over a bump while cornering does disrupt road contact and will begin a slide even if everything is correct. But start by looking at the inside of your front tires for wear, then move to have the alignment and camber checked to make sure it is in factory spec. Good luck!

 

Go with Mich. Sport 4s.. or be brave like me and run the Mich. Sport Cup 2’s.. Rain is tricky for Cup’s but the Traction is amazing.

 

I have Sport 4s on my car, thanks for the advice on Sport Cup 2s because on my last track day I pretty much toasted the Sport 4s.
