.............. a member put up a post a few months ago asking for help with the front of his car being very light to steer at speeds above 85 mph, turns out that he fitted a rear spoiler and not a front to match.

Steve - This was exactly the point I was trying to make earlier in the thread about going non-standard. The 'Knock-on Effect'.

each to their own, but i think that some people get upset / angry almost when you say you like to keep them more or less standard, also whats the point in having it chipped or the like to give more BHP and so on if all you do is drive on the roads, unless it makes it more drivable.

ok. i dont understand why it has it on here as its never worked.
also on here its got about send private message but i dont think that works either.

richard bernau,
if you read the post above , i said the younger guys mod them with roof spoilers and so on, porsche and a lot of other car maker's agree that it will unbalance the car if not done with the rest/other parts of the body. a lot of people fit a rear spoiler on a non sport 911 and not the front giving more down force on the rear but makes the front lighter, not a good thing. also some take of the rear spoiler for the more original/old look and leave the front on. a member put up a post a few months ago asking for help with the front of his car being very light to steer at speeds above 85 mph, turns out that he fitted a rear spoiler and not a front to match.

I guess I generally agree with you but just to keep things interesting I will respond.

The tat the younger guys buy from Halfords and nail to their bootlids (or whatever they do with it) will have no real effect on handling balance or downforce (IMHO). If it did, Halfords would be in a position of legal risk should someone have an accident while driving their POS with the Halfords tat nailed to it. I guarantee it is designed to be completely ineffectual. Hence, I wouldn't worry what they do with their Halfords tat [:D]

Now what about Porsche spoilers? You have to remember that any spoiler is part of a complex interaction of aerodynamic systems. For example, the ride height of your Porsche will have as great an effect, if not greater, on lift than any front or rear spoiler. The front spoiler simply keeps air out from under the car and accordingly, if you run your car about an inch lower than standard you have acheived approximately the same thing. So running a rear spoiler without a front spoiler is not necesarily a bad thing provided you have some understanding of the effect of the changes you make. So what if you just add a rear spoiler and neglect the front and keep all else standard? Still not the end of the world IMHO. Its not like a F1 car without a front wing. The spoilers on our cars reduce lift (no downforce unfortunately and even with the full spoiler package they still have positive lift) but the absolute amount of the reduction is not that great (IIRC). If someone can post the Paul Frere numbers you will see that they are measured at pretty high speeds (something like 120mph?) and that the reduction is something like 150kg. So I am a little surprised that the effect is even noticeable at 85mph. Regardless, my point (if there is one [:D]), is that the change you make to your car is not really the bad thing. It is the ignorance of the effect the change has that is bad. Provided you know your car is a tad lighter at the front then adding a rear spoiler without a front one is not a cardinal sin. You may have a car that tends to oversteer, in which case, the rear spoiler only package might be just the ticket.

BTW, if you (or anyone) is 100% happy with their car as it is then by all means don't touch it. I just don't think that leaving it standard for the benefit of someone else makes a lot of sense if there is something you think could be better - and believe me, there is a lot that can be improved on a 3.2. Great cars they may be, but they are just cars built to a price (I submit the fuse box, your honour), not the holy grail (2 religious analogies in one post!).

Just my $0.01 (not even $0.02 worth).
 
Richard Bernau,
Got to say I don't usually like Indian Red 3.2's but yours looks stunning with the grey wheels and carrera script (first noticed it in "The last of the evolution").

Can I ask what size wheels you run, do you have spacers etc, love the low squat look and would like to get a similar set up.

My general thoughts on customising are:

Better to keep it looking as though it's an original Porsche option, so:
- Fuchs alloys (but whatever size you like)
- Spoiler (sport or non-sport as long as it's standard)
- Steering wheel (Standard wheel with crest or RS version looks best in my opinion)
 
Just spotted this thread and would like to add that these cars are obviously close to all of our hearts and as such I feel a sense of duty to keep mine original - otherwise what will we be left with in another 20 years.

These are classic cars and in my opinion, customising them is like painting a moustache on the Mona Lisa.
 
Whatever takes your fancy, as a 'fun' car is very often an extension of the owners personbality etc.

I have loads that I want to do to my car, but time, space, cost and not least skill are all factors. I bought my car as a second car for me. My daily driver is my trusty Passat TDi estate that has done 140,000 miles in just seven years and does everything that I would not want the 911 to do.

I am not saving my car for anyone, nor do I consider it an investment. An interesting analagy is when one of my staff asked how I could afford to run a Porsche ? I replied "How can you afford to throw away £300 a month on your new Mondeo!". My 911 will pretty much always be worth what I paid for it, and therefore any money I put in to it is purely for the hobby / fun / interest of it.

I would like to track / hillclimb the car, but also want to use it for regular road trips. Therefore, sensible modifications to the brakes, suspension, steering, interior will achieve this, without changing the BHP or gearing in any way - that way it will be suitable for me. If the next owner wants to return it to standard (as Andy said earlier), or indeed tune it more, then good luck to them.

So I say, do your own thing, but most of all enjoy your car for how you want it.

Just my 2p worth.

And finally, so that RB doesn't wear out his copy of the picture, this is how I would like mine to look :-

I replied to Greg offline but here is a quick run down.

The wheels are Turbo 7/9x16 Fuchs with 225/45 and 245/45 tyres. Wheels are anodized/polished lips (not matching front to rear!) with centres painted in Halfords Silver wheel paint with clear lacquer over. They need repainting as the paint is cracked and stained.

The car is low - not sure of the measurements but its as low in the front as you can sensibly go. It has rack spacers to counteract some of the bumpsteer. Rear heights are set to get close to 0.5 degree nose down rake. I run just over 1.5 degrees negative camber in front and nearly 2.5 degrees negative rear. This means that even with the 245s on 9s I use 14mm of spacers with just enough clearance. Most people will use 9s with no spacers. I have 5mm of spacer on the front and clearance is very tight. On my second set of wheels - 7/8x16 Fuch - I use standard size 205/55 and 225/50 and there is ample clearance. Without the negative camber, clearance is tight even with this set-up. I had the front fender lips rolled some years ago.

I wouldn't go quite this low without the stiff suspension to go with it. I have 22/29mm hollow torsion bars and Bilstein dampers. I would in hindsight go for 21/29 or 22/30 next time as I like a bit more oversteer, however 22/28 is also a popular combo and may be ok for pre-G50 cars.

The side stripes came from one of the UK retailers (Porscheshop?) that I cannot recall, but you can get them a lot cheaper in the US.
