How do you think the aerodynamic improvement of the GT-Racing spoiler compares to the bridge spoiler from Deutsche Nine? Both product pages tout increased downforce.

Reason: added GT-Racing spoiler picture

In reality, there's no spoiler that will give downforce. What they do is reduce lift at speed. Yes, they'll provide aero benefit, but only a wing will overcome lift and actually create some downforce. Also, keep in mind the importance of matching the aero improvement in front via a lower spoiler, or in the case of a wing a proper splitter. A car with unbalanced aero is a handful at speed, and is no fun at all.

Exactly! I'm sort of surprised the factory didn't seem to come up with much for the front end re downforce Michael? I think for most people expressing interest in this piece it probably won't make too much difference unless they're regularly going well over 100mph. One other thing to bear in mind is that unless the new custom piece is designed with drainage you'll collect a ton of water if in heavy rain when in traffic or parked.

This may sound like semantics, but I want to understand. It sounds like you are saying it the downforce a spoiler provides is less than the amount of lift our cars would have, so the net effect is the it only reduces lift. Downforce of a spoiler/wing would have to be greater than lift, to have net downforce. correct?
So back to the question at the top of the quote. Does anyone know or have a feel for how the Lemans/GT spoiler compares to the 968 Turbo S/Deutsche Nine bridge spoiler in reducing lift?

Yes, thanks for this. I've updated my n-a car with a turbo bumper and added a fiberglass lower lip spoiler. This improved the light feeling the car was getting at higher speeds, but now feels imbalanced.
This is a DE car. And we've got two spots at local tracks where I'm really noticing the aero imbalance. One is a pavement irregularity where the road course leaves the drag strip at Pacific Raceways, hitting that at 140+ mph can be exciting. The other is a 100 mph crest at Oregon Raceway Park where there's often a significant crosswind.

Okay! Maybe I'll get my order in with DeutscheNine and see how lucky I get with fulfillment...
