Bill Prawn Posted February 28, 2006 Share Posted February 28, 2006 Does it? Reading a couple of threads recently it seems there is a difference of opinion. Ok at up to 70 it won't make much difference but what about high speeds (on private land obviously)? Views from drivers who have removed it would be great.

Supra_Nish Posted February 28, 2006 Share Posted February 28, 2006 No diff noticed here Cornering etc at sensibleish speeds seems fine, no probs in straight line at 14.0+ either (not going round a bend at that speed!) Quote Link to comment Share on other sites More sharing options...
BURT Posted February 28, 2006 Share Posted February 28, 2006 surley it must be there for more than just looks,,, it creats down force to help traction etc.... but maybe you wouldnt notice it unless really pushing the car to its max while cornering... there is quite a big thread on this somewhere...

Supra_Nish Posted February 28, 2006 Share Posted February 28, 2006 Yep it was discussed before. In my opinion the vast majority of us aren't able enough drivers to push it soooo hard that the lack of spoiler becomes an issue. Quote Link to comment Share on other sites More sharing options...
VIL Posted February 28, 2006 Share Posted February 28, 2006 Why would you want to remove it? I want my sup to look like its doing 100mph standing still and dumbing down the looks just makes it look odd IMO! However i`m sure there are others out there who hate the rear spoilers!

Guest chiefvinso Posted February 28, 2006 Share Posted February 28, 2006 Visually it makes the supra look cack too (IMO).... soz to those offended, not intended Quote Link to comment Share on other sites More sharing options...
chilli Posted February 28, 2006 Share Posted February 28, 2006 I can't remember the exact figures, but at 70mph I think it creates something like 66lbs of downforce. Ok so that's not that much, but think where it is located, at the rear, right over the rear wheels. Also this force will go up proportional to the square (IIRC) of the speed (or is it cubed?). Anyway, the point being that for very high speed driving (100 - 120+mph) this is going to be producing considerable downforce which adds grip but also slows you down. So you are trading top speed for grip and handling/stability. This is especially important on a powerful rear wheel drive car, where the rear tyres struggle for grip anyway. Having said that, the rear spoiler is not the only source of downforce, so it's only part of the picture. I'd guess I'd feel nervous with very high speed cornering without a spoiler, but I guess you get used to the limits of the car, whatever they are. In any event, I think the rear of the car looks strange without a spoiler, too rear heavy and unbalanced - but that’s just a personal preferences thing though of course. If I were doing a top speed run (straight line of course) I'd remove it temporarily. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 28, 2006 Share Posted February 28, 2006 I doubt you will notice any difference below about 130, I can't. If I bought another MKIV the first thing I'd do is take the damned thing off, and sell / bin it. Looks dated and very boy racerish, IMO, and is far from being a good design from the reduction of lift point of view, it's just a styling gimmick. Purely a personal thing though.

RedM Posted February 28, 2006 Share Posted February 28, 2006 The one on the right looks great compared with the other two although the widebody kit probably helps. Quote Link to comment Share on other sites More sharing options...
peter richards Posted February 28, 2006 Share Posted February 28, 2006 i can feel another low spoiler thread coming on , surely someone ie the traders can source these from somewhere Quote Link to comment Share on other sites More sharing options...
lockys96 Posted February 28, 2006 Share Posted February 28, 2006 check out the calder racing supra CRD, over 1000hp and goes over 200mph, no spoiler there. the JUN 250mph supra had a small tail spoiler, it doesnt make much difference Quote Link to comment Share on other sites More sharing options...
Supra_Nish Posted February 28, 2006 Share Posted February 28, 2006 Before: After: I think it looks far better without Quote Link to comment Share on other sites More sharing options...
terribleturner Posted February 28, 2006 Share Posted February 28, 2006 I think it looks far better without Im the other way, i think it doesn't look as good When i was spoilerless for a few days i found it didn't actually feel the same going round bends at speed. But didn't Terry run at Elvington on Burnters without a spolier doing top speed or something?? Quote Link to comment Share on other sites More sharing options...
Guest chiefvinso Posted February 28, 2006 Share Posted February 28, 2006 There seems to be a bump in the middle of your bonnet..... remove that and put the wing back and and hey presto you have a proper soop Quote Link to comment Share on other sites More sharing options...
Ian W Posted February 28, 2006 Share Posted February 28, 2006 think you could be right mate. i reckon mine will be coming off this weekend!! what holds them on btw? Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 28, 2006 Share Posted February 28, 2006 Now there's an idea Taking it off makes the supra look like an overgrown Celica, which fits with my 'stealth' look philosophy. It may also make me think twice before pushing the loud pedal at silly speeds and get myself into trouble again. Is it easy to take it off then? It might be interesting to do acceleration tests with/without. I bet decent traction control will make far more difference than the wing.

letmeshowyou Posted February 28, 2006 Share Posted February 28, 2006 I remember watching Leon Green take his off at Pod to try and squeeze into the 9's (bear in mind his has that extra extension on the back) - he was convinced it would make the difference! (though think about the terminal speeds he's doing and maybe thats why) Quote Link to comment Share on other sites More sharing options...
Supra_Nish Posted February 28, 2006 Share Posted February 28, 2006 Very easy to take off, two bolts accessible from the plastic lining underneath. Its then held on by some glue and a plastic clip, just "wiggle" back and forth (the spoiler!) until it comes loose. I've only covered mine with grommets for the time being to see how it would look. The bonnet needs to be swapped back to a j spec, complete the smoother look. Quote Link to comment Share on other sites More sharing options...
chilli Posted February 28, 2006 Share Posted February 28, 2006 check out the calder racing supra CRD, over 1000hp and goes over 200mph, no spoiler there. the JUN 250mph supra had a small tail spoiler, it doesnt make much difference at 250mph even a small spoiler would make quite a large difference. no doubt they used it to aid high speed stability, not to improve cornering ability though! Of course if you are aiming for top speed you want to minimise the spoiler size without potentially making the car unstable. Conversly if you want maximal high speed handling you want to trade off some of that top speed for downforce (= grip) - it's a balance to be made. On the road I'd say grip is more important than top speed (how often do you max out you cars top speed anyway?). To say you generally don't notice the difference (between having a spoiler and not) is one thing, that doesn't mean the difference isn't there - you just need to reach the absolute limit under repeatable conditions to quantify it. A supe without a spoiler is like, erm? a roast dinner without the gravy? an icecream without a flake? etc you get the picture lol Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 28, 2006 Share Posted February 28, 2006 At the supra's natural top speed (180 according to Toyota), the rear spoiler creates 250-odd lbs of downforce, that's not chickenfeed. The question: Is it worth making it work for it's money and risk eating porridge and playing indoor games with the other inmates? This politically-correct country will make minced meat of anyone caught at such speeds. Quote Link to comment Share on other sites More sharing options...

monkey76364 Posted February 28, 2006 Share Posted February 28, 2006 Well mine is off at the moment as per my thread and i like it but i am putting a spoiler back on !!! does seem to be lighter on the rear but then i had the Veilside hug bugger on the back lol Quote Link to comment Share on other sites More sharing options...

Ian W Posted February 28, 2006 Share Posted February 28, 2006 yeah. well, where the bumper used to sit anyway...just so i can see what kinda mess will be left if i remove it and how much i'm looking at to get it smoothed off etc. Quote Link to comment Share on other sites More sharing options...

From memory it leaves 3 small holes either side, no other mess. No damage to paint etc. Think 2 holes are round and one square? Quote Link to comment Share on other sites More sharing options...
