On a daily driver that sees some canyon action will swaybars be a possitive move or a waste of $? What about strut tower bars?<p>Damon

<br>What is special about the A4, don't all Audis have the double firewall?<p>I believe in harder springs/shocks and stock swaybars in all applications, not just due to recent posts about A4 A/R bar problems.<p>Todd W

Well,<p> As a past owner of two Coupes (84, 86) and a 90 ('88 FWD), those particular models did not have a double firewall, just like my 16V and my G60 do not either. On the other hand, the A4 does have double firewall.<p>Regards,<p>Oscar<br>

Nah, look closely at the firewall, it is essentially a three-sided box. That is vastly stiffer than any cross bar could ever be.<p>The old bar argument is bandied about by P car owners. Most of the flex comes into play in the top bushing of the shock/strut assembly, and the top bearing. Until you go to urethane or metal it is just an incremental improvement (still needed in some other designs like my 240Z).<p>On our car, the bar will transfer energy in a side or diagonal impact exactly where you don't want it. I heard once of an insurance company that wouldn't pay for a repair beacuse the non-factory specified bar damaged the other side of the unitbody.<p>You can set up a suspension either way. Stiff spring/shock, soft sway or vice versa. Stiff sway is a good street compromise, no sway is a good rally setup for true independat suspension. SCCA rules don't allow spring changes in stock, so stiff shocks and one bar changed is the option there.
