Run flats, LSDs, and DSC
Two questions,
1. I've heard getting rid of run-flats makes an uber difference in ride quality. Does it affect the handling in a negative way? I know that the suspension is "designed to use run-flats," so I'm wondering if there would be a difference in handling. 2. Would putting an LSD on a 335i make DSC not function as it normally does? I've heard that an LSD makes an unbelievable difference in traction, but I don't know if it will affect DSC in a bad way. |

Sorry, I'm no expert so don't quote me on this.
1. The handling will depend mostly on what particular make/model of tires you get. In general, most people think non-RFTs improve the handling. 2. Check out this comprehensive review of the Quaife LSD by E92Fan in which he even talks about DTC/DSC: http://www.e90post.com/forums/showthread.php?t=100072 And another thread which might be useful: http://www.e90post.com/forums/showthread.php?t=262831 And one more: http://www.e90post.com/forums/showthread.php?p=4375576 |

Most people that have dumped the All Season RFTs usually have a very positive experience with their replacements.
I have the Summer Only Potenza RFTs with the sport package 18" wheels. I really don't mind them at all. Car feels very nimble with these tires. Only reason I may not get them again when time comes to replace is due to the cost. $300+ per tire is rediculous. |

Non-RFTs and Quaife LSD here
Either change was big improvement for me DTC/DSC is not affected, just now requires less intervention |

if you track your car, they say the rft's arent bad at all. its because of the extra stiff sidewalls in comparison with regular tires
