Fix for rear knock and rattle in exhaust
 

For two years I have suffered with an exhaust rattle when de-throttling and knock in the drivers rear wheel area.

After many Porsche mechanics adivsing a complete suspension replacement a very cleaver ex-Aston martin mechanic found the problem.

The control arm link. I bought two for the left and right hand side from Pelican parts ($314 for two) and they arrived as scheduled. Once fitted both problems resolved. I to this day cannot work out how the control arm link affected the exhaust.

I now believe these should be replaced every 50,000 miles or so. The performance improvement in handling is incredible.

Are these the 'drop links'? (a part number would be great)
