ok. one of you suspension gurus please educate me. in a hard left curve with a slight uphill grade i managed to get the left front wheel light enough for PSM to kick in hard. what's the best way to stiffen the chassis? sway bars? strut braces? both? (and i know someone is going to say driving lessons. )

the stock dampers and springs on the C4S seem plenty firm. i just want to get rid of the flex. my initial thought was stiffer sway bars because they're already part of the suspension. strut braces seem like an afterthought, otherwise porsche would have designed them in. braces make sense geometrically though, because they form kind of a (sideways) four link with the rest of the suspension.

opinions?

 

In a 4S your chassis is plenty stiff. A stiffer front swaybar might help push the inside wheel down but it is limited by the travel of the suspension. In an off camber turn this is hard to address.

Driving lessons?

 

The front allready has a brace near the battery.Some of the TT guys like H&R sways,im leaning that way myself.

 

996 have a front strut brace as OEM, don't waste your money on this.

 

the sways will help a little, the front tower brace wont do anything since it is very close to the firewall. I have similar results from the same road conditions you describe, the car also detects the pitch of the car and wheel slip, so psm will quickly chime in...
