As per Audi, the 1999.5 A4 will have: 1) re-tuned, low-friction gas-pressure shock absorbers and selective local reinforcement of the body, 2) fine optimization of the elastokinematic properties of the suspension, 3) separation of the spring and shock absorber mounts in the torsion-crank rear suspension, all of which are susposed to ensure a more sensitive response, extremely good acoustic characteristics, and a significant increase in comfort.<br> <br> If I get the SPORT SUSPENSION and/or QUATTRO, will any of the aforementioned changes be relevant<br>to my car?<p>Thanks.<p><br>
