If the absorber and tyre are bad in shape, autofoam the chasis will have negative effect. My experience is, after I autofoam the chasis, the previous tyre setting (33psi on front and 28psi on rear) can't handle the load. The car is easier to skid and behave in a weird manner at its grip limit, overall it is an understeer characteristic. Further fine tuning on tyre pressure (35psi F, 29psi rear) gives me positive results, and immediately the cornering ability increased while giving me better comfort compared to no autofoam + less air pressure tyre. Besides this, if anyone has a worned out absorber, you can feel more 'hitting the chasis' feel in most situation. In my opinion, this is because autofoam did its job well, making your chasis stiffer, so the road vibration, pot holes, curbs or whatever shit will stress your tyre and suspension more than before.

So now it’s the pros,

I feel the absorber can do its job better in absorbing the road gaps, and the tyre can stick better on the road (and my tyres are almost worned out). Cornering speed didn't increased due to tyre limitation, but at the same cornering speed, the horizontal G is less. I have Titan absorber tuned for street racing purposes, once the tyre pressure is set correctly, the whole cornering ability moves up at least 1 level. On the north south highway around the changkat jering terowong area, I am able to go uphill and downhill cornering at 110 / 130kph respectively with ease. The cornering G is as if 90 / 110kph before I have the autofoam. Road gap absorbsion is good too. Although the car still going up and down when travelling on wave alike road patches near to the Penang stretch, at least I won’t have that kind of ‘Perodua Kuda’ feel  I mean, instead of driving a kelisa, I feel like riding a horse.

The most impressive one is the braking G. The rear lift under braking is pretty much negligible, even under full braking (until wheel lock). This gives me a lot of stability before any corner entry. Once the front tyre clipped at the apex, the accel G under wide throttle open is less too. In short, there is less body movement after I have applied autofoam.

The best part is, I'm using the comfort package only. I wonder how good the track package can give me.
