Looking at updating my C2 with a new front PU, Sills and a Rear Spoiler and have a few in mind from Design911.com

I am aware that its not recommended to get a rear spoiler without a new front PU otherwise it would upset the handling.

I was told that once you get a new front PU with increased downforce it would be OK with most rear spoilers.

I am looking at a GTR front spoiler with a GT2 rear. has anyone got positive or negative experiences mixing and matching parts?

Thanks,

Rob
 
Looks like a nice combination - I particularly like the 'GTR' front end. However, it's fibreglass, which I personally definitely don't like. Have you seen them in the flesh?

If it were my money, I'd go for the aerokit with genuine front PU and side sills, which doesn't seem a bad price at £1695. If you decide to go the fibreglass route, I would keep the original front PU and rear spoiler if I were you, to put back on when you sell the car.

Can't comment on the aerodynamics, but surely Design 911 can give you advice on the combo.
 
Fibreglass is an expensive option in terms of repairs. Catch it on a kerb ever so slightly and it'll splinter instantly.
 
Hmm.... was thinking of a new front PU for mine. What other options than fibreglass are there?
What's the Porsche OEM one ade of?

I guess I should know by now but been out of it for a while
 
haha.haha all these years and I just learned what PU meant. Always wondered. Thanks for that mate ;)
 
Hi Richard (and everyone else) for your comments.

Design 911 seem well informed but I am also aware they are selling so I was looking for a 2nd opinion, not that they have given me any reason to doubt.

I was told that you should have a new front PU to add downforce if your going for a rear spoiler. I was also told that the additional downforce only makes a difference after 120 mph (which, personally, I think is a little high). I was told that they should be fairly interchangeable once I have more on the front to balance the rear etc. I am sure their is of course a science to this but how much would it matter in the real world?

Wasn't aware (or considered) of the difference between OU and Fibreglass in terms of light damage etc. - worth considering.

I have seen it in the flesh, unpainted, and looks good. I dont want to be to much Too Fast Too Furious but I want it different as I was looking to upgrade the car but unless I go for a facelift there is no real difference in the car and I would potentially inherit other peoples problems.

For fear of being Chavvy I was going to get my wheels re-furbed and painted anthracite, the top of the spoiler matching but not the struts, and probably a Carerra graphics along the side in a matching colour. Shoot me down if thats going to look crap but I would like it a little different and it would at least look and feel different to me!

Not a great fan of the Aerokit rear spoiler so maybe an aerokit front/side & GT2 rear spoiler would be better?

Only concern about the GTR front is it has air vents in the side (as a turbo/c4s) and I wouldnt have any at the rear. Would it look unbalanced like that?

The other alternative is a 'Turbo Look' front end? And maybe a matching carbon GT3 RS top with would definately be a but ronnie racer?

Objective and personal comments welcome!

Thanks,

Rob

ps.. Good point about keeping the existing parts.
 
Rob, have you had a read of this thread?
Rodney & I have the Carrera rear spoiler & a tiny little lip spoiler seems to be a requirement at the front for that. With a GT2 spoiler I'd have thought you'd need something a little more substantial than that to balance things out... (think cross-winds at speed)
 
Hi Nick,

Thanks for that. I did read the article some time ago and it was before I was thinking of the changes. Good thread and agrees with my thoughts.

It would appear that most people had the lip and it makes a difference as one would expect, however, if I read it right it says the Carerra rear spoiler is OK without a front lip at some point?

The GTR front spoiler definately 'looks' like it would produce more downforce on the front but I am not an engineer. The GT2 front end would no doubt produce loads of additional downforce but looks a bit square and blocky on the pre-facelift 996 where I have seen it on the post-facelift and it looks good.

Out of interest, at 120+ with 3 up (on the a/b's of course!) mine was starting to float a bit.

Thanks,

Rob

That is only valid pre 7/01 cars as the TSB that this quote comes from dates to 2000.
Post 07/01 cars need to have the front lip spoiler if they have the Carrera rear spoiler.

So Beershark is right - the cutoff date was for cars built before 07/01 which don't need a front lip spoiler when specifying the Carrera spoiler.

Rodney is correct - I should have qualified that. Just another benefit of driving a pre-facelift - more downforce! [;)][;)] Maybe that's why I don't get that floaty feeling at high speed.

Hi Rob

The point I was really trying to make is that there's a world of difference between plastering a Saxo with addon plastic tat where the top speed isn't high enough for any of it to matter a jot, and changing a high performance car's aerodynamics in an ad-hoc (& dare I say, unscientific) way. Manufacturers such as Porsche spend millions to ensure their bits work together properly; with the best will in the world, Design911 can't hope to do even 1% of the testing Porsche do. If you want to modify your car for "pose value" that's one thing, but if you want to use the performance, be aware that very bad things can happen with the wrong combination of addons & that your insurance company might well use the mods to try to wriggle out of a claim.

But Rodney & I don't get floaty at high speed because we've got the little lip spoiler [:D]

PS
Anyone else noticed how people are qualifying mentions of high speed by saying it was on the a/b after this appeared?[;)]
 
Nick, what are you trying to infer here, no-one's mentioned MPH anywhere? [:D]

Rich, I'm surprised about the lip spoiler not being necessary on the pre-facelift cars. The Cd of both cars is suposed to be the same, but the facelift cars are supposed to have less lift.
 
Apart from the aerodynamic issues, any thought on the Boy Racer look. Happy for it to look a little different but not like a kit-car.

Also, not really a fan of the Aerokit rear spoiler.

Cheers,

Rob
 
Rob,

IMO the 996 GT2 rear spoiler is stunning, but the GT2R front is a bit OTT, won't it also be a bit low for daily use?

p.s Good luck with the sale on Ebay.
