As the title says going to go with some new Ohlins on my E93. Really disappointed with stock suspension from BMW and Ohlins get great reviews. I can feel the squirly rear end on rough roads oand corners, but was wondering how much of this may go away with quality dampers on the car? I hope the rear isn't to soft when the top retracted also since Ohlins doesn't have a specific E93 kit.

Thanks, ML

Based on my research when putting on the TCKline DA suspension you don't have to but the spongy feeling could likely be made worse. I debated back and forth and spent the money on M3 bushings and M3 bits at the same time as suspension. It will also depend on the stiffness of the springs you use how bad the impact will be. Heavier springs will cause more of a pogo stick effect. Also tighter rear end helped with front end stability.

Others may have different opinions but this is what made me drop the extra cash.

^ true. The Ohlins rear springs are super soft at 400#, softer than oem rear springs. So, there will be less stress on the rear subframe bushings.

It also depends on how many miles are on the car. If you are getting up there in mileage, the bushings will become relatively squishy. I usually suggest replacing them, regardless, after about 40-50k. It is not mandatory because of the low spring rate, but I would suggest it be done at some point.

Thanks All.

Mike, the car is relatively new. Less than 10K and I don't want to live with the sucky suspension for 40-50K. I want to enjoy it!!May put Swifts 700 lb/in on the back, especially since its a convertible and heavy in the back.

The M3 rear subframe bushings virtually eliminate that floaty, disconnected feeling in the rear of the car. It becomes more noticeable when you install stiffer rear springs as they pry the rear subframe away from the chassis on compression. To save labor and money you could press poly inserts into your oem bushings, which will get you close to M3 bushings. Also consider Meyle or M3 front tension struts.

I did my Swift spring conversion on my V2s back in the day and ran 400/800 spring rate on stock rear subframe bushing. At first I didn't notice a big difference but those 800s really began to wear out my stock bushings. So if you are doing everything at once then I say go for it!
