Re: A few other questions (archive)

Your message is very interesting, since I got delivery of my 2001 740i sport (Cosmos Black/Sand) a week ago, this is my 2nd 740 (had a 1996 Jet Black/Sand il, some time ago and I have also owned 8 M3s, just traded-in my 1998 M3 Coupe to get this car. Anyway I have been researching about body kits/exhausts and springs myself. Here are my findings:

1. I have talked to the technical experts at Dinan and been talking to a salesperson/friend at Bavarian AutoSport. The figures you are quoting 1" front and rear drop are based on the standard i/il, since the 740i Sport already sits 3/4" lower than the standard i/il, with the Eibach pro kit or any other kit, you should only expect a drop of 1/4" or maybe 1/2" at the most. BMW will not honor warranty if anything other than factory or Dinan equipment is used on the car. Talking to the guys at Dinan they stongly recommend a spring/shock combination, they claim that it will reduce the roll by 50%, height drop is still going to be 1/4"-1/2" as with Eibach. If you have any other info about this, I will greatly appreciate.

2. How do you like the Dinan Chip and Cold Air Induction? Do you feel a noticable increase in HP/Torque? I know Bavarian AutoSport is developing a chip in colabration with Autothority, which maybe more aggressive, but the warranty issue may dictate getting a Dinan.

3. Have you considered Remus Exhaust? I am considering that, although I had a SuperSprint DTM tips on my 1998 M3, I liked it.

4. I am considering an Alpina front lip, I like it better than the AC Schnitzer or the Racing Dynamics lip, I think it is alot classier for the 740. Alpina does not sell the rear apron, so I may have to go with one of the other two. Any Comments.

Lets try to keep in touch, we are both trying to do the same thing and can benefit from each others findings.

Thanks.

Thanks for the info. I have a few other questions. I believe that your car is the silver 740i shown below on the forum, not the black one shown in the links. If correct, then your car uses the AC Schnitzer body kit and I assume that you have rectangular exhaust tips. Whose exhaust? If so, have you published a picture of the rear of your car.

I have a 2000 740i Sport Black on Black. I have already upgraded the car with a Dinan Chip and Cold Air Induction and clear lenses I am thinking about the other following changes and wonder what you think of them?

AC Schnitzer body skirts
Addition of a rear antisway bar
Addition of Eibach pro-set springs, lowering front and rear by 1 inch
Supersprint exhaust

I looked at a Supercharger kit, but I believe that the Dinan system is too expensive ($12k) and I don't know of anyone with any experience with the $5k ESS system, even on the 540 forum site, which is more high performance oriented.

You seem to know about body kits for the 7 series. Do you have a full list?

I saw from your E-mail address that you are at Ohio State. My brother is head of the Horticulture Department at OSU.
