Just finished talking with my local tuner about installing H&R Stage II on my Sport. He says the drop (in inches) described on the H&R site is for ''normal'' i or il models and that installing them on a Sport will not decrease the ride height, anymore then it already is. Basically I'll be trading apples for apples. Comments anyone? Please discuss amongst yourselves.

Now....apparently (says him) Eibach as of May 5 has a new spring coming out that will lower my cars ride height an additional 1.5'' in the front and 1.3'' in the rear from it's current factory sport stance. Again, comments anyone.

Has anyone heard of this new product lunch.

Montreal7,

I have a 2001 740i Sport and I have installed the UUC springs, (lowering 1.5" front and 1.4" rear). The car is deffinately lower and the ride quality is just about the same, maybe a tad firmer.

Cheers,

Hey AMP01,

If the UUC springs ride quality is about the same or a tad firmer than Sport springs, than it is not as firm as H&R's. I did H&R I on my previous 97 740i, it was for sure firmer than our 01 stock Sport suspension. Dave Clement has said that he thought the front dropped by about 2" vs 1.4" advertised by UUC. I thought our Sport was already 1.3" lower in the front compare to non-Sport. So if you notice a drop in the front, I would assume it would be more than the 1.5" to be noticed. Got some Pics from the side of the car in its present form? I am about to buy springs, already have Bilstein HD's sitting in the garage.

2001 750iL

Installed UUC springs

Dropped 2" in front, .5" in the rear. I measured a million times. :)

Someone needs to get Rob Levinson to change the stats on his website. Question, could this be because Brett at KMS used 740's as test mule and gave those #'s to Rob. And the 750iL you and Dave have drop more in the front due to the heavier engine?

First of all, thank you. I don't know if it is optical illusion, but the rear looks to have dropped more than 0.5" vs. Bread car. Looks more like the 1.4" stated by UUC. The front looks like it dropped slightly more than our Sport.

JLe38,
That's no optical illusion, it is really at the height that is stated by UUC. I've never been more pleased with it's aggressive stance and the handling is much improved. Here is another comparison with TXDarth's sport:

Granted, the hardware in Baby's suspension is custom ProTrac DA shocks w/ coil overs, however the net drop is very close to the H&R set up you were speaking of.

I measured my distance before and after the drop without changing tires, air pressure, or anything. I checked the height immediately, the next day, the next week, etc. Still got the same numbers.

I think the front of the 750 is heavier which is why it dropped further than the 740. The rear should technically weigh more than the 740 as well due to the dual batteries and additional hardware in the rear interior, so I can't explain the rear only going down .5" on my car. I completely disabled the level-ride BTW so I know the car is resting entirely on the springs with no assist. Perhaps the 750's rear-end sit's lower to begin with than a 740i or 740iL, hence it had less to drop.

I'm going to have to meet up with Dave Clement sometime (I seem to bump into him all the time anyways) and compare our measurements to see if we both got the same results. We have different wheel setups, so we'll have to measure from the center of the wheel hub to the fender lip to get accurate measurements.


Just as a general statement, if UUC ever comes out with a rear spring to drop the car more I'll be all over it. I'd like to bury the top of the rear tire behind the fender and level out its stance a bit.

Montreal,

I can tell you that my car is noticeably lower that my buddy's Sport. Granted I started from a regular i but the drop is still more than the S. By the way, I went with Stage II H&Rs.

Good luck,

I just looked over the H&R site to see the specs for the Stage II springs (was considering a swap).

They list the 740iL as dropping 1.9" in front and 1.3" in the rear. They list the 750iL as dropping 2" in front and .5" in the rear. These numbers are consistant with the UUC springs I have installed. Perfectly.

This leads me to believe that the 750iL just simply sit's lower on the factory springs in the rear than the 740's do. The weight must bring them down a bit more. So there is less to drop. The UUC spring was considerably shorter than the factory one, but it must also be stiffer therefore giving less drop than one would guess by looking at it.

So, if all this is true. A 750 should sit lower in the rear than a 740 from the factory, and with the same set of aftermarket springs. .8" in either scenereo. I'd like to get measurments from 740iL owner sporting UUC springs to verify. Measure from the center of the wheel hub to the top of the fender to eliminate wheel variances.
