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

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
