Considering a 968/944 S2 as a daily car limited mileage

The 245/45/16 sidewall is 2.3% smaller than the 225/50/16

There is approx. 6 more revolutions per mile which is very small
but will have a very slight effect on your speedo reading and will also put more weight bias on the rear axle compared to the front.

If there was any Porsche than wears all 4 tyres equal it would be from the early 924 transaxle range.

I've messed about a lot (25+) different wheel diameters, rim widths and tyre sizes and find when fitting a wider (than recommended) tyre
on a too narrow rim the ride comfort is good but the handling not as sharp as there is too much flex and slop, and tyre wear can be more because the carcass heats up more and the rubber wears quicker.

For example your front rim width is 7" (177.8mm) and with a 225mm wide tyre this leaves 47.2mm nearly an inch each side.
And the rear 8J @ 203.20mm with a 245mm tyre is not as severe @ 41.8mm (20.9 per side)

The other point is any tyre's first 3 numbers do not correspond directly to the section width (sw) but are always wider.
Eg a 205/55/16 is actually 215mm wide, so the above calculations are even more far apart (Rim width v tyre width)

Porsche did use the 245/45/16 size but on 9" Wide rims (228.6mm) for the 944 turbo and they did also use a 225/50/16
on a 7J for the more comfort orientated cruiseship 928.

Thanks Tony, I've only ever run my 968's on 16's and 205/55 front 225/50 rears, the one time I test drove a cab on something different - 18" rims and IIRC 245/45 front and 265/40 rear, although it may have been 225/50 front and 245/45 rear - it was horrific, very hash ride, heavy steering and tramlined like crazy. First cab I test drove when cab hunting, I walked away from that one even though it was GR and tip, just what I wanted (but not owned by an enthusiast, he did not even know there was a drain in the filler cap area!).
 
If I can afford it what is the better car a 968 Sport or a 968 Coupe or is it best to go on condition/service history and mileage. I'm torn between a very nice looking low mileage Coupe in red and a black Coupe Sport with about 50k more miles.
 
Condition/service history first, mileage second. For example, if belts/rollers have not been done in the past 4 years, you're looking at about £400 for those, maybe heading for £1k if water pump needs changing and cams need checking. Also ride comfort - chances are the coupe is on 16's and the Sport should be on 17's and firmer suspension so may not be as comfortable. Front/rear PU and oversill seals is another possible bugbear as they shrink, all can be DIY replaced but rear is a bit of a mission. A link to the ads for the 2 cars would help us advise you. Personally, I've always loved the FE Porsches in Guards Red (I've had 3!!) and am not that keen on black.
 
Darren, that's a hell of an optimistic price for a coupe even at 71k miles. I like the full leather interior and sports seats, but I wonder if it's had a respray as the oversill seals appear red instead of black and the side repeaters are clear rather than standard orange. Also the belts and rollers were done in 2013, accepted wisdom these days is they need changing - at least the belts, and any rollers found wanting - every 4 years. Admittedly with low annual mileage you can get away with longer gaps (please don't ask how long I let my coupe go through ignorance!!) but the result of a cam belt failure would mean at least a replacement 1/2 engine as pistons would meet valves! Although 16" rims were standard on the coupe, 17" were an optional extra, but those look like Boxster Twists rather than Cup 1's or 2's that a 93 car should have.

IMHO keep looking, that one is overpriced by quite a few thousand and will not sell.
 
Thanks Chris, the prices of the majority of Coupes/sports seem to be in the 20-25k bracket irrespective of mileage, being a novice I thought that the car looked "good value" given the mileage even though the guides I've seen seem to suggest £15k for a Concours/Dealer Coupe and nearly twice that for a Club Sport. There is a member selling a red sport with just over 60,000 miles but he wants more than £30k!

I will continue to look and try to get a drive of a Coupe and a Sport to see what I think of the differences and hopefully a sensibly priced Guard's Red car will come up soon. Prices or expectations are clearly on the up.


 
Hi guys and girls
I need help please , I have a 944s2 cab and need to get the roof down as the rocker switch isn't working , is there a way to take it down and up without power "manually", any help or advice would be greatly appreciated many thanks Gary.
 
In the interior rear quarter panels each side is a roughly 1 1/2" diammeter plastic cover, lever both out, behind are the nuts (IIRC takes the plug or wheel nut spanner) to manually raise or lower the roof.

https://drive.google.com/file/d/0B3FX3V_kb7JvZi1PNE8zQm5zYUU/view?usp=sharing is the manual for the roof, download it from the link.

First thing I'd check is the microswitches on the latches, have you pushed the roof up far enough before operating the switch? Are the microswitches working properly? If you do end up lowering it manually, do a little at a time each side evenly, 'cos if you damage the bows etc your wallet will take a big hit - and some parts are NLA. A friend a while back drove off with the roof not properly latched, it "opened" at about 70mph, repairing the damage was about £1k and took some time to obtain the required roof bows etc.
 
Hi thanks for the reply , do you need to take the bolts right out and then literally pull down and up by hand or just loosen the bolts a bit ?? ?? And can this be done as a alternative way of loweri and raising ?? Thanks Gary.
 
Gary, download and read the roof manual from the link. Personally I would not touch those bolts until I was sure I'd lifted the roof far enough to disengage the microswitches, tried the normal switch both ways a few times (mine sometimes needs a couple of tries before working) then checking the microswitches in the top of the windscreen.
 
Apologies if this sounds patronising, but you have got the key in the correct position in the ignition?
 
Thanks Chris, sadly I will be on holiday then. I am on the waiting list for full Goodwood Racing Club membership and it's about 1.5 hrs from me so not too bad a location to get to.
 
I've had my sport 7 Years and it now has 158,000 miles on it, it has got an excellent service record and runs superb, so mileage shouldn't be an issue if it's been looked after, you're not putting space miles on and they are for driving.
 
Had my coupe for 3 and a half years no a daily but I can get it out the garage after sitting there for 3 weeks and fill up with fuel and do a 400 mile round trip

there are just great cars when looked after
