In Reply to: Downforce?... Evo2 lip vs Evo3 splitter posted by C///MR on August 05, 2001 at 23:31:18:

My car has had both fitted by the previous owner.

In the pic you'll see the EVOII lip and what looks like a Sport Evo splitter. The splitter is infact 'non-genuine' as it is not adjustable and appears to be a merely a black fibreglass lip fixed in position.

I wonder whether this was a purchased product of whether someone just made it up? I have therefore wondered what it's effect might be. Good or bad?

Also my car has a Sport Evo gurney flap on the rear spoiler ( see other pic). This has a genuine BMW stamp on it....but I can't see any means of adjusting .... it has a row of 6 big screws underneath but I can't see how these can be moved in relation to the spoiler?

I have also wondered how much straightline speed these add-ons might be costing me?

Any input appreciated.
Does anyone have any windtunnel data on these two front end spoilers. I recall reading the splitter adds 66lbs downward force. If this is so what effect does the Evo2 have? What about a Evo2 lip with a splitter, does anyone do this??
Thanks for any info, Chris
