I'm planning on changing all the suspension bushes to Powerflex.
Only one problem...there are 2 partnumbers for the front bushes with the following comment :
On the front wishbones the later cars have a larger 45mm bush, in this case please use PFF3-501. For earlier cars with a 30mm bush please use PFF85-201.
How do I know which one I need? I have a 02 S3.
