Stiffer chassis no, unless the car has a weakness most people are not going to notice a stiffer chassis.puckaveli wrote:It's all pointless really, unless you have tons of other suspension upgrades and drive the car on the limits of traction, which no one does on public roads, you will NOT notice a slightly stiffer sway bar and chassis.
Sway bars, on the other hand, are VERY noticeable and subtle changes there make the car feel different. They're usually the last thing that gets decided on in suspension tuning. When they say suspension tuned at the Nürbergring, that's what's going on. The suspension engineers, NVH engineers, and some marketing types are at the track with a truck full of sway bars and shock absorbers trying to decide on the final tune of the car. The bean counters are sitting back at the office screaming "enough already, we need you to sign off on the car so we can start building them!"
You'd need to take a ride w/ me sometime then...I feel the stock rear sway bar giving up the ghost quite often on the back road twisties (can't say about any chasis issues). I throw it around hard and the car always remains between the lines 
....that's the beauty of owning and driving one of these things, it handles.
