The SLS rear spoiler...
is actually functional, because there is 8kg of downforce in the back. The front end is where is the lift is happening (all 41kg lift @ 124mph). Getting actual front downforce is very difficult because that's where the wind hits the car first. It's always tricky to balance between usability (ie. having a front nose that isn't too low so that it would scrape everything) vs. reducing front lift.
On most mid-engine cars, getting a reasonable rear downforce isn't too difficult because most of them have flat underside with ground effect. This, combined with a well engineered rear diffuser + spoiler, will generate a good amount of downforce in the back. On the 458 and Aventador, they both produced front lift as well. It's only the Mclaren that has a small front downforce (2kg front downforce) and the Porsche GT3RS isn't too bad either (at 2kg front lift).
Downforce (or lack of it)
So here is an interesting topic for all you car fans.......what is downforce and how much of it do you have on your car? This topic came across when I was reading the Sports Auto Supertest on the Ferrari 458. In Sports Auto Supertest, one of the testing c...
Good to know! Good research!
Any Porsche 911 driver who has driven the car at high speed will notice that the car feels a little light in the front, especially through the steering. This is a common problem that Porsche needs to adjust and reduce. The Mclaren's numbers are impressive...
I wonder if MB has jumped the shark in regard to its exotic car development
Thanks UNOTAZ for your real world experiences and research in regard to SLS and MP4 driving experiences. If I understand the stats correctly, the SLS has more lift than downforce which implies to me that the retractable spoiler if more a "gizmo" than prac...

Thanks for clarification for the neophyte
Although I misinterpreted the implications of your prior post, my comment was intended to be tongue-in-cheek about marketing hyperbole, i.e., unlikely barrel roll commercial, and performance claims that remind me of over-inflated claims of monitor size ba...
Thanks, Unotaz, for the specs. Interesting note on the GT3RS...
the WanderingPurist told me he specifically didn't want the front end lift because 1. long term reliability concerns 2. the added weight on the front end. Yet, an acquaintance, once national karting champion (and so, in his mind, qualifies him as a very g...
LOL!
No worries, your GT3RS is still one badass car! It's interesting though to see new sports cars that are coming out with "active aerodynamics" like the 991 Turbo. Of course, the Mclaren P1 and the Ferrari "LaFerrari" will introduce a new breed of active ae...
PuristS perspectives...
Hi, AV, Thanks for being a supporter over all these years. Something that I find to be fairly unique (is that an oxymoron?) on ThePuristS and PuristSPro is that while we are fans of the brands and their products, we are not blinded fan-BOYS who can see no...
