Kaamos Posted March 24, 2009 Share Posted March 24, 2009 Hi all.... I read somewhere that the rear wing was not only for cosmetics, it actually provides downforce..... now I'm wondering : what if you have the wing removed, doesn't it come at the cost of some grip-loss ? (I'm about to buy a wingless supe, the wings comes with it but is not fitted so I'm just wondering about having it re-fitted or not...). Link to comment Share on other sites More sharing options...
brettjones Posted March 24, 2009 Share Posted March 24, 2009 i would imagine its only at very top speeds not at 70 mph so i will be fine Link to comment Share on other sites More sharing options...
Kaamos Posted March 24, 2009 Author Share Posted March 24, 2009 Then what if I'm hanging around derestricted highways in germany ? Link to comment Share on other sites More sharing options...
AlanM Posted March 24, 2009 Share Posted March 24, 2009 If you are going to be 140mph + I believe it makes a difference (but I have never tried both options myself) Link to comment Share on other sites More sharing options...
Scott Posted March 24, 2009 Share Posted March 24, 2009 Spoilers are for downforce, removing them lowers the downforce. Thats the reason the veyron only gets its top speed once the spoiler is down. Less resistance. Might be a bit iffy for cornering though. Link to comment Share on other sites More sharing options...
Mike Posted March 24, 2009 Share Posted March 24, 2009 AFAIK it's purpose isn't to offer down force - it's there to provide stability when braking from speed. Lots of people run cars without the wing on here... I've never heard anyone mention it makes any difference. Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted March 24, 2009 Share Posted March 24, 2009 It must provide quite a bit of downforce as when i drive at night with the hid's on i dont get flashed, but when i'm doing over 70 I notice the cutoff is higher on roadsigns and people occasionally flash me. I've put this down to the spoiler pushing the arse down at speed, just like having a load in the boot. Link to comment Share on other sites More sharing options...

Chris Wilson Posted March 24, 2009 Share Posted March 24, 2009 I have driven loads both with and without the "wing". Whatever it does isn't very much, I am hard pressed to tell the difference. It probably kills SOME lift from the roof and tailgate shape, rather than actually creates downforce. If i had another MKIV I would remove the somewhat dating wing and not bother a jot about any potential "downforce" issues. Link to comment Share on other sites More sharing options...
merckx Posted March 24, 2009 Share Posted March 24, 2009 (edited) Spoilers are for downforce, removing them lowers the downforce. Thats the reason the veyron only gets its top speed once the spoiler is down. Less resistance. Might be a bit iffy for cornering though. The veyron is in a different league altogether.

little num Posted March 24, 2009 Share Posted March 24, 2009 (edited) well i had a sierra cosworth before my supra and i repainted the spoiler once then ran out of paint, so i went to get some more without it fitted, i went down the M5 and would you beleave the rear end felt all soft and crap, so i came back refitted it and went down the same bit, ahhh much better, so id say it does help at higher speeds.

Gaz6002 Posted March 24, 2009 Share Posted March 24, 2009 The veyron is in a different league altogether. Just a little. For a start the Veyron self-adjusts its ride-height for optimum downforce... well i had a sierra cosworth before my supra and i repainted it once then ran out of paint, so i went to get some more without it fitted, i went down the M5 and would you beleave the rear end felt all soft and crap, so i came back refitted it and went down the same bit, ahhh much better, so id say it does help at higher speeds. Do you mean a 3 door? Because the whale-tail is quite a lot bigger that the Supra spoiler so I'm not really surprised! Link to comment Share on other sites More sharing options...
Scott Posted March 24, 2009 Share Posted March 24, 2009 The veyron is in a different league altogether. I didn't say it wasn't, i just gave an example of an active spoiler, and the difference it makes, in a relative term that everyone can understand Do the really really fast supras run with spoilers? 230mph ones? I would be surprised if they did. Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 24, 2009 Share Posted March 24, 2009 The Sierra Cosworth RS500 had a rear wing that was optimised for group A saloon racing, so you'd expect it to do more than LOOK fast Link to comment Share on other sites More sharing options...
Nic Posted March 25, 2009 Share Posted March 25, 2009 Toyota claimed on some of their adverts for the Supra that it added downforce, can't remember off the top of my head how much and at what speed. Link to comment Share on other sites More sharing options...

Kaamos Posted March 25, 2009 Author Share Posted March 25, 2009 Thanks for all your replies mates, happy to learn I'm not going to do off-road as soon as I hit the throttle haha Plus I guess removing the wing gives a somewhat better sight from the inside rear view mirror. Removing your wing is good for health and safety ! Link to comment Share on other sites More sharing options...
Kirk Posted May 16, 2009 Share Posted May 16, 2009 sorry to revive thread BUT what if you added say a little boot tip spoiler after removing stock spoiler? would that make much difference at all ? Link to comment Share on other sites More sharing options...
