991 Technical Forum
 I want to know about the new 991 RSR front suspension. The official description says it has a "double wishbone" design. Can someone tell us all about it? So far I have seen no tech articles on it. Len

 Anyone know about this front suspension??? Seems like quite a change brought about by wide front tires requiring a limited camber change. Len

Len,
The 991 front suspension still uses a McPherson strut with a lower control arm, wheel hub carrier, and trailing arm. The latter is connected to the lower control arm by a hydraulic mount to dampen high frequency vibrations and control wheel movements (toe changes).

Yes, the street 991 is still McPherson strut, but I read where the 991 RSR now has "A Arms" at the front because of the wide tires. Just trying to verify this and learn about it. Len

Found this on the Porsche UK website for the 991RSR under the "Technology" section......... "Featuring a double-wishbone suspension at the front and multi-link rear axle, adjustable shock absorbers and anti-roll bars, the chassis superbly handles any manoeuvre – on straights as well as chicanes". Guess this means no more McPherson struts for their ultimate GT car. Len
