suprasam Posted April 13, 2005 Share Posted April 13, 2005 Seen a few Supras advertised with Active Front Spoiler - is this standard and how does it work?? Sounds cool i am guessing its like the Mitsubishi GTO one which deploys at a certain speed?? Was this standard across the range?? If not is it possible to refro fit one??

JohnA Posted April 13, 2005 Share Posted April 13, 2005 It's standard in UK models mate. It extends downwards at motorway speeds. Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 13, 2005 Share Posted April 13, 2005 Retro fitting one fo rthe look wouldnt be too tricky, getting all the electrics wired up etc would be a bit trickier I'd imagine. Quote Link to comment Share on other sites More sharing options...
suprasam Posted April 13, 2005 Author Share Posted April 13, 2005 Fair enough just so i know!!! Does it really make that much difference i know there a few cars that have such devices Boxster, Corrado, Mitsi GTO, Nissan 200SX????

Bobbeh Posted April 13, 2005 Share Posted April 13, 2005 Helps increase downforce at the front so it doesnt go light at speed. Quote Link to comment Share on other sites More sharing options...

suprasam Posted April 13, 2005 Author Share Posted April 13, 2005 I am sure the S15 Touring model has active front spolier??? Suprasam Quote Link to comment Share on other sites More sharing options...
Homer Posted April 13, 2005 Share Posted April 13, 2005 The front active spoiler makes a fairly big difference in front end downforce at 80mph+ speed. When mine was removed (after FMIC fitting) the steering felt light and the car unbalanced at high speed, particularly when at WOT. Quote Link to comment Share on other sites More sharing options...
michael Posted April 13, 2005 Share Posted April 13, 2005 Retro fitting one fo rthe look wouldnt be too tricky, getting all the electrics wired up etc would be a bit trickier I'd imagine. Would the wiring already be there on the models that don't have it? I know a lot of makers use the same loom for all the models but just blank the plugs off for the bits that aren't fitted. I have a spoiler, the aluminium frame, spoiler ECU, switch and brackets in the garage, what else would be needed to fit one? (Obviously not on my car, I already have one that's disabled thanks to the FMIC ) Quote Link to comment Share on other sites More sharing options...

hadyn Posted April 13, 2005 Share Posted April 13, 2005 200SXs/Silvias dont have active spoilers S13 and S14 definately dont S15 im 90% sure doesnt either Quote Link to comment Share on other sites More sharing options...

suprasam Posted April 13, 2005 Author Share Posted April 13, 2005 Yeah and if its not screwed on properly might deploy below the front bumper.......LOL Quote Link to comment Share on other sites More sharing options...
JohnA Posted April 14, 2005 Share Posted April 14, 2005 The front active spoiler makes a fairly big difference in front end downforce at 80mph+ speed. When mine was removed (after FMIC fitting) the steering felt light and the car unbalanced at high speed, particularly when at WOT. very true. The car's shape is like a wing (short path for the air below, longer on top) so it creates LIFT as it moves through the air. Not what you want during high-speed runs. The lower spoiler reduces the airflow beneath the car, so the 'lift' effect is also reduced and the car feels more planted down. The rear wing creates some downforce at high speeds, but only on the rear axle, so this has the effect of actually lightening the steering a bit (at the expense of better traction of the rear wheels) Quote Link to comment Share on other sites More sharing options...
dude Posted April 14, 2005 Share Posted April 14, 2005 I must say with my Bomex the car is rock steady even at 180+++ speeds Homer , have you tried a top speed run with the Do-Luck ??? Dude Quote Link to comment Share on other sites More sharing options...
dude Posted April 14, 2005 Share Posted April 14, 2005 There was a thread on SF about some guys making a complete carbon undertray for the whole car that had been aerodynamically designed . Dude Quote Link to comment Share on other sites More sharing options...
Aerotop Dave Posted April 14, 2005 Share Posted April 14, 2005 People have reported this difference and while I'm not disputing it I do wonder about all these aftermarket bumpers. I guess with the active spoiler you can make a direct on the spot comparison, whereas it's a bit more tricky to do this with the standard bumper and an aftermarket one. However, I just wonder how many of them are designed in the wind tunnel and how many are just designed purely for cosmetic looks. I would suspect the latter myself, but don't know for sure. The really interesting one would be the Veilside nose I imagine. That little 'lifty-up' bit in the middle must force air underneath the car, so surely that's gotta be bad for front end grip. If the active spoiler really does make such a difference, then I wonder why more people with aftermarket noses don't notice a wishy washy front end at speed...

attilauk Posted April 14, 2005 Share Posted April 14, 2005 If the active spoiler really does make such a difference, then I wonder why more people with aftermarket noses don't notice a wishy washy front end at speed... because most aftermarket noses are lower at the front end then the stock one?

Jake Posted April 14, 2005 Share Posted April 14, 2005 My stock-fronted RZS does not have an active front spoiler but it feels very stable at 160+ I'd like to fit an active spoiler to the car but purely for cosmetic reasons. Quote Link to comment Share on other sites More sharing options...
Homer Posted April 14, 2005 Share Posted April 14, 2005 Homer , have you tried a top speed run with the Do-Luck ??? The do-luck seems to have at least as much downforce as the stock with the active spoiler down, possibly more. Best I've been up to since getting it back is 150 and it was absolutely fine, not a trace of light steering. Quote Link to comment Share on other sites More sharing options...
Aerotop Dave Posted April 14, 2005 Share Posted April 14, 2005 because most aftermarket noses are lower at the front end then the stock one? That's a fair point. Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted April 14, 2005 Share Posted April 14, 2005 Its not just about how low the lip is. Its how the force is applied across and over the front of the car. Quote Link to comment Share on other sites More sharing options...

My Calibra felt pretty stable at 160+ the few times I took it that far. However, compared to the Supra, it was flimsy and unsettled at anything over 120. It's all relative. If you have a chance to drive a stock Supra with the spoiler down at those speeds, only then will you have something to compare it to (again assuming wheels and suspension are similar) Quote Link to comment Share on other sites More sharing options...
