Title: Can the MR2 fly?!
Post by: Anonymous on March 27, 2006, 23:25
Im sure Im not the only one but when my MR2 gets to about 100mph it feels like your driving on ice! Maybe a rear spoiler would help. It feels like any faster and it may leave the ground!    s:shock: :shock: s:shock:

thats the front getting lite not the rear

a rear spoiler will just make it worse

Yeah, it can fly no problem, but you will need to Mod.
I suggest starting with the TTE wing mod and the TRD rear flaps - plus you'll probably need a couple of jet engines, or you could just drive off a cliff - depends on what sort of flying experience you are after really.

HTH   s:wink: :wink: s:wink:

In all seriousness - yours doesnt sound right. Mine is fine at speeds over 1.0 leptons - when I've had the chance to reach these on a private runway of course.

Maybe I'll try a bag of cement in the spare wheel storage in the front!

My previous car was a Seat Ibiza Cupra (the 1.8 turbo one) and this felt solid even up to about 125mph, I guess the MR2 being so light makes it feel less stable. Was quite a shock the first time I drove it on the motorway on a windy day!

I'm betting you have an early model ?

Post by: ninjinski on March 27, 2006, 23:46
Sounds like an early model alright - I'd add xtra bracing undercar but check your tyre pressures and tracking first.

26psi front
32psi rear

Ex-Cupranet user by any chance?
I moved from an Ibiza to the MR2 too. I do know what you mean about it feeling lighter.
I put this 1/3 down to the crap tyres fitted, 1/3 down to the height, weight and different sensation of driving the car, defo not as insulated as VAG products, as well built but not as solid feeling, sort of more in touch with the car - which in time you will get used to, and 1/3 down to technique - the level of smoothness required is so much greater, but this does make the car more rewarding to drive.

I reckon with a tyre change all traces of this will be gone. Certainly adapted to the car and am much smoother with power application at speed now.   s:wink: :wink: s:wink:

Quote from: "markiii"if it's a 99 I'll tell you several bits that will be missing

1. look under the bumper, there should be a rubber airdam that runs most of the width of the bumper. it's about an inch thick and sits about 6-8 inches under the car

2. Bet you don't have the plastic spats that sit in front of the rear wheels?

3. Might not have the plastic spats that sit in front of the front wheels?

thess were added sometime before 2001 and weren't even on my 2001 car

cost is very low to fit them, and they transformed my highspeed handling

Cheers Mark

1) This is going to sound incredibly dumb, but its late! Im assuming you mean under front bumper? - Cant recall seeing this.

2) Cant recall seeing these

3) Have these.

Is it possible to have some and not others?! Mine is a 2000W car.

Cheers

Roo.

Its possible, nay probable, that you're in the same (flying) boat as me Roo, as per the thread Markiii refers to above.

I've not corrected with these overpriced placcy and rubber thingies yet, so can't comment. But strangely enough, just shifting the toolkit and a few other odds and sods into the frunk has helped quite a bit.

Would anyone with the spats and front rubber air dam be able to take photos when they have a chance please.

I've been down to the car to have a look. Seems my 00 is missing the rubber air dam and the rear spats - but have the front.

Thanks

Roo.

I can do that for you on Thursday if no ones done it before then.

Cars gone to mates garage for the bodykit to be fitted

YIPPEEEEEEE !!!!!!!

Going to collect it thursday evening after work, will do it then  :-) :-) :-)

Just realised, thats a bit strange mines a 2000 plate too ( although mine is actually near enough a 2001 on the registration date ) unless owner before me had these added on - cant see it myself though, as the car was 100% standard when I first got it.

Post by: Anonymous on March 28, 2006, 22:38
Rear Spats - could be a MY01 thing.
Bet mine is a MY00 and yours is a MY01 car - if so, that would explain the absence of these.

As I said - I have the front spats.

Either my front bumper has been messed with, or  the front air dam and rear spats were introduced to from MY01 cars on.

Indeed:
Quote from: "markiii in the other thread"thess were added sometime before 2001 and weren't even on my 2001 car

Yeah I'm an ex seatcupra.net member.
Mine is a 2001 model and think it has everything thats on that list, certainly got those plastic things in front of the wheels anyway. Just had 4 new Toyo tyres fitted 2 weeks ago and the tracking done, to be honest it felt exactly the same with the old tyres which were 4 different makes (not sure why the previous owener did this!). Nothing bad's ever happened at high speeds but just makes me feel a little nervous at times! Nevermind encourages me to drive a little slower!

Post by: edward.carter on March 29, 2006, 09:17
I think i have got the big plastic strip across the front but i dont think i have got the four in front of the wheels, be interesting to see the pics to see if i am missing anything as the front certainly feels light at "im late for work speed!"   s:lol: :lol: s:lol:

The two screw-bolts in the wheel arch fasten through the plastic into a meccano-type metal bracket on the other side, so you'll need a couple of those too.

right pretty sure i dont have those, presume the front are similar?  so on my very late 2000 i only have the strip under the front bumper!

can anyone explain how the rear ones work? i see if you have those in front of the front wheels how this may stop it going light, at speed. but how do rear ones affect it?
Title:
Post by: spit on March 30, 2006, 09:55
Confused me too Edward, but I assume the rears use the same principle to help keep the rear planted.

Any aerodynamic gurus here?

ps the S'chat article also posts a virtual wind tunnel pressure image without spats.... no idea what it means, but here y'go  s:wink: :wink: s:wink:

Has anyone got a photo of the front air dam as I know I aint got the spats, but not sure about the airdam, when I look under my bumper it is completely smooth, no rubber running the full width or anything.

Mine's a 2000 X Reg.

Cheers

No photos as yet but I'll get some from my local showroom when I've got a moment (unless someone else does it first)....

..... but from your description (and car age) you're without.

The rubber is set back about 3 inches from the front edge of the bumper and protrudes downwards about an inch (in old money!) so you'd certainly know if it was there.

Having just got out from under the Porker after changing my inner wheel arch liner (the old one disintergrated last week after an argument with a speed hump) I have discovered that the spats are missing from the front of my car, I wondered why it had been feeling wandery, I remembered this thread and it could explain why. The wheel arch liner that arrived has very handy screw holes for the spats to go in, but no spats.  After spending £91 on an expensive large bit of plastic I am a bit annoyed about  now having to pay out for these...  Boxa.net would of told me to go to the local Porsche garage   s:roll: :roll: s:roll:
Title:
Post by: spit on April 8, 2006, 16:12
Liz, It just shows that they do make a difference eh? Amazing what an inoffensive piece of plastic can add to the handling  s:lol: :lol: s:lol:  Looks like more spending for you....ahhh the joys of Porker ownership  s:lol: :lol: s:lol:  

Back to the '2 (  s:wink: :wink: s:wink:  ), and thanks to Gazz for letting me crawl around on his driveway in the pelting rain, here's the picture of the front lip as promised. Top arrow is the plastic lip, bottom arrow is one of the wheel spats.
(http://img445.imageshack.us/img445/4391/spats2xn.jpg)

Gazz was gracious enough to let me drive his car. In relation to handling, his car is incredibly sure-footed compared to mine. A lot of reasons for this, but I reckon the lip contributes by helping to root the front end.

As for the back end, I'll pick that up in the TTET buyers' poll thread. I've pledged not to swear, so give me a moment to search for the appropriate superlatives  s:wink: :wink: s:wink:    s:lol: :lol: s:lol:  "Wow" is probably a good place to start.

pass, if you've got about 50K lyeing around we could always do a bit of research in a wind tunnel and find out, even a bolt head can make a difference, hence why all rivets on planes are countersunk

Thanks for posting the picture. I took a look at mine today and i have the front wheel spats but don't have the central spoiler strip or any spats at the back. Mine is a late 01 car on 51 plate (euro import)

I do try and keep the front storage bin fully loaded up though. I have a full size spare wheel in there and all the other related bits and bobs as well and it seems pretty stable even in a headwind.

Anyone got a part number for the under spoiler piece?

EDIT - Sorry i should have read the other thread. They were listed there.

rubber front splitter 76851-17070
nuts for above 90179-06286
bolts for above 90119-06827

Anyone who's put on a body kit got a spare one lying around?

Hi Guys,

Thanks for the photos everyone, I'm missing all of these on my 2000 model. Really would like to get them on as I notice it getting a bit 'light' on the motorway so anything that could improve matters would be great.

Can anyone tell me how easy they are to fit? Does the front splitter require the bumper off or the frunk lining to be taken out to gain access to the other side of the nuts? Or is it possible to somehow reach around under?

Same applies to the spats front and rear, how simple a job is this?

Rich
Title:
Post by: kanujunkie on April 9, 2006, 22:03
they all bolt on from underneath, but i'm not sure if youll hve the bolt holes, although it should be a simple job to put them in yourself
Title:
Post by: markiii on April 9, 2006, 22:48
all bolt holes already exist,

easy to fit
Title:
Post by: Anonymous on April 9, 2006, 23:15
Thanks, is it tricky to get on the other side of the bolt holes to put the nuts on then? That's what I was getting at. Or are the holes pre-threaded so it's literally just a case of offering up the splitter, spat etc.... and doing a bolt up?
Title:
Post by: spit on April 9, 2006, 23:29
You can fit it in situ. I'm looking at the exploded diagram that MrT printed off for me. It doesn't show the fixings, but if you look back to Jaso's post it lists the nut and bolt part numbers. If you want to save a few bob, any decent hardware n's&b's and maybe washers will do. The bumper already has slots to receive these.

Just ordered my front air dam and rear spats plus associated nuts and bolts.

Got a quote of "around €80" for the air dam and the two spats not counting the mounting hardware.  My car already has the front wheel spats.

What's the procedure for mounting the rear spats (or is it obvious)?
Title:
Post by: markiii on April 10, 2006, 11:39
if memory serves there are 2 existing plastic bolts that hold teh arch liner on.

these then screw into teh hollow centre of those.
Title:
Post by: spit on April 10, 2006, 11:40
Its pretty obvious although I haven't done it to testify.

Spats have two screwbolts that go through the liner and fasten into the overpriced piece of meccano that you should have ordered with 'em (x2)(58747-17020). There's also a Placcy fastening to hold it to the sill underneath.

(edit - looking at Mark's post followed by mine, perhaps best if you do it and let the rest of us know   s:wink: :wink: s:wink:  )

Is this a problem?

Sorry if I'm being thick about this.
Title:
Post by: spit on April 10, 2006, 18:02
Looks like you'll need to offer-up, mark and drill?

I think thats why the rears need the metal bracket for the screw-bolts to grab into....there aren't any threaded holes behind the lining, and therefore no pre-drilled holes.

.....but I'm in guessing territory now.
Title:
Post by: Ernie Ball on April 20, 2006, 16:37
Well, got the front air dam + fixing hardware and the rear spats.  But they forgot the brackets for the latter.  Even without those, it still cost me €109.
