A local Dinan dealer said that the kit is for the

coupe and that the 650 convertible is probably not rigid enough for the shorter springs. Wish that the Dinan tech told me that. he just told me that there was no lowering kit for the 650.

Re: Need lowering kit for my 2007 650CIC

Taking a look at how the springs are installed, there is no additional "complexity" involved.

If you buy springs and it rides like crap, is too low or too high, what are your options?

Just spoke with a tech at Dinan and he said that

they do not have any springs/lowering kit for the 650. A local Dinan/BMW dealer told me the same thing.

Re: Need lowering kit for my 2007 650CIC

The Dinan website does not list a lowering kit or springs and several calls to them have produced nothing bu unanswered vm's for the only sales rep who can answer my simple question. I may try a local Dinan dealer, but wanted to get the facts from Dinan first. I do not want the expense and potential complexity of coilovers. Your comments are most helpful, as I do not want to change the dynamics of the car, just lower it a bit.

A very FESTive place where they discuss BIMMERS

Re: Need lowering kit for my 2007 650CIC

where are you selling at? always like KW.

Re: Need lowering kit for my 2007 650CIC

**Shameless plug warning** (I'm selling my set, but not here, I have them listed at a very FESTive place)

Now, the reality......

IMHO, the best setup is coil overs. I just took a set of KW Variant 3 coil overs off my 650i (I bought an M6)

Disadvantages of springs
- The lowering measurement is fixed, no height adjustment
- The ride quality is fixed, no dampening settings
- The rebound is fixed, no adjustment

The KW V3 coil overs solve all those issues. The only downside is that they are expensive, many times more than traditional springs.

Sorry, I really don't know the answer.

It would seem feasible, but doing this might weaken the structural integrity of the stop itself. Just a thought.

I'm sure some one on this Board will have an answer for you. Good luck.

Re: Need lowering kit for my 2007 650CIC

Thanks, Bob, Eibach springs will be 1.2" lower, but they don't come with bump stoppers like Dinan's, can I just cut OEM stoppers by 1.2"?

Re: Need lowering kit for my 2007 650CIC

I had the Dinan kit installed on my 2006 650i several months ago.
It lowered the car by approx 1" and did not change the ride quality in any way. I didn't notice a great deal of change in cornering either, perhaps a mite stiffer.

Personal opinion only, but I think lowering it any more than that would the corrupt the aesthetics of the car.

Need lowering kit for my 2007 650CIC

Just had my new 2007 650CIC Sport last week, changed to 20" wheels/tires, SSR GT3 20x8.5, 20X9.5, now need to lower it about 1", any advice? which brand? don't like too bumpy ride, H&R, Eibach, or Dinan? and any idea how much I can get from the stock RFT tires(less than 400 miles)? thanks.
