Suspension Questions
I recently had the Dinan Spring & Handling kit installed on my 335xi, handling is better but I'm still getting that bouncy/floaty feeling and have to hold my breathe if i see pothole. I've been recommended the KW V3 Coilovers Complete kit, which I think is on the high end of suspension systems. Does anyone have experience with this or other systems on a a 335xi? Bonus, do you live around central Jersey and can I see them in action?

If I understand this correctly, you have just swapped you springs with Dinan springs and bump stops but you kept the stock struts/shock absorbents? If so the bouncy ride is to be expected as those xdrive shocks are too soft for the Dinan springs. You need different shocks now (Bilstein B8) to match those stiffer springs.
You gonna need to change the RFT's also if you still have them. Not really cheap, I know, but unfortunately there is no other way at this point. |

Coilovers are a better option because springs and shocks are matched by design. Stiff springs and soft shocks will produce the symptoms you are describing. Bilstein B8 shocks may be the answer - can't comment, no experience with these shocks and Dinan springs. I suggest to research this further. There are many coilover options. Typical decision criteria: - Drop range - What is adjustable: rebound, dampening - Cost - Manufacturer: warranty, reputation KW Street Comfort coilovers provide the option of minimum drop and a significant improvement in handling at approximately $1600 plus installation. The debate of RFT vs non RFT tires is perhaps as old and as vocal as xDrive vs RWD models. RFT tires have stiffer sidewall, produce more noise, and weigh more. They will handle differently. My vehicle came with Bridgestone Potenza S001 tires which lasted 20K miles. I just replaced them with the same tires. My vehicle - a daily driver - has KW Street Comfort coilovers with minimum drop. I prefer tires with stiffer sidewall and the luxury of not having a spare tire in the trunk. |
