Does it work on pre-lci? I'm trying to stiffen the rear of my car.

 

Trust me I have tried reinforment bars on my previous cars that I tracked and I felt minimal difference. To say it makes that much of a difference is basically stating that BMW E60 chassis flex way too much and I find that very hard to believe. There are a lot more points that account for more flex than what these bars provide. For instance, replacing rubber bushings for polyurethane makes a huge improvement and eliminates a lot of flex in the suspension.

Hey, if you guys felt a difference thats awesome and that's all that matters. And for the price its really good considering a typical strut bar goes for $200+

 

were can I get the polyurethane to upgrade the rubber for our cars?
I what to do this mod.
I am a handing mod guy and less on power mods

 

If you really don't believe it, if you are ever near El Paso, we should meet and swap cars for a ride. There are some nice scenic drives not too far from here. And if you are near in the warmer season we can go to New Mexico for some Fishin!

 

I do believe you that is why I asked, I always whated to change these.

 

Not you bro I was talking to socale39 LOL.

 

o sorry

well to add our e60 dose flex too much, after all it is a big car unlike the small sports car or the 3er

 

Actually, the 5 series has been known to have a rather stiff chassis. Check the page below for further details:

Tony, I appreciate the offer, really I do. If you believe it changed the car I cant agrue with that as I cant speak from personal experience with this particular mod.

 

Sorry Pingy, no one makes replacement poly bushings for our cars currently. I contacted a few companies that can do it but interest was limited so I dropped it.

 

here the prove that our E60 chassis flex way too much.
ricky in our HK e60 club has installed the M5 bars, if BMW design these bars then the chassis is not that stiff.
