This is not entirely M5 related, but I hope I can get some suggestions from here. I recently picked up a 2001 M5 which needs to be repaired. I also have an earlier model E39 DINAN 5 which has Stage II suspension on it.
While the M5 is undergoing surgery and what not, I figured I can use the wheels off it since the tires are literally brand new Bridgestone Potenzas. The DINAN 5 already had OEM Style 65 M5 wheels on it with 265/35 rear Sumitomo tires.
I had always thought the DINAN looked like it was lower in the back.... almost like it was sagging a little. I asked the guys at DINAN about this and they said it all looked fine. I even went as far as replacing the front springs with H&Rs to hopefully drop the front a bit more.
Any-hoo. I put the M5 wheels & tires on the DINAN yesterday and now the rears will not stop rubbing.... every bump, every major undulation on the road, any 35 MPH+ turn, etc. It is worse on the Right Side. The rear tires are Bridgestone Potenza 275/35/18. I would not have considered them too big for the car. The DINAN 5 is a 1998 E39 540 and as I said, it has a Stage II DINAN suspension.
Any ideas or thoughts would be greatly appreciated. I have a set of DINAN M5 Struts & Springs kit that I was thinking of installing. Would these fit the 540 anybody know?
