The ride height you see in my picture is original Stock springs and Stock Sach abs.
As for the tyres, i changed mine to GT Radial Champiro HPY. Its a Y rated tyre (rated up to 300km/h) and is GT Radial's top of the line tyres. The Potenzas that came with the car were wearing off and the 225/45/17s at the back were causing tram-lining and harshness.
The GT Radial Champiros are OEM to some Benz and BMW models in China, so i am quite confident in them. They also supply a lower range OEM to the new proton preve. Happy with them so far. Very quiet, and wet performance is excellent! Plus, its VERY comfortable. The best thing is the price is realy affordabel - just rm350 for the front (225/45/17) and rm450 for the rear (245/40/17). They are not as good as the Goodyears or Bridgestones, but i think bettert than Falkens.
Downside is that the soft compound causes a bit more body roll around corners. I was considering between Nexen N6000 and the HPYs. Settled for the HPYs because the quicksave boss said the N6000s could be too soft for our Bimmer set-ups.
No regrets so far.
