Brake / Suspension issues

T-Rex57 · 10-26-2016, 04:28 PM

Hey guys

I have a problem with my car where braking at speeds above 90km/h (55 mph) in a straight line causes the car to dive to one side and become unstable, and it will begin to fishtail (with no steering input, VDC on).

In general the car doesn't feel planted at all at any speed, but is very floaty and unstable at speeds over 90 (55mph) of late. The car has stock suspension, 38, 000kms, 2011 model. I've done basic things, checking wheel nuts are torqued correctly, pressures all set to 38PSI.

I have new(ish) tyres (2 months old on the rear and 5 months old on the front, with 2000km driven this year on the fronts) and newish brake pads (4 months old, Project Mu NS400) on the car.

So I'm not sure if it's a general suspension problem, alignment, joints or a combination of those. What should I be looking at/for under the car this weekend (Mechanical noob)?
