New to me 991.1 GT3, next steps

[Adrian-9iafn]

I will get a geo, detail and possibly ceramic coating and refinish the wheels in satin black. Also thinking about black PDLS, the lights are PDLS but not black. Any thoughts on geo for mostly road use and occasional trackday (probably one a year), I live in Bath so don't want to travel too far for the geo

[Flat0ut]

Congratulations on the new arrival - not sure on the geo but would interested to hear if you can change the lights to black without replacing the whole units? Where did you buy it from as a matter of interest?

[Porsche911R]

Why geo it, is there an issue with how it drives ?

I would also keep the wheels that colour also.

[Adrian-9iafn]

I always like a geo to get the corner weights set and dial in a little less front toe (close to zero) and a little more camber, just me. Oh and bring the ride heights down a fraction

The car was from Sutton Coldfield OPC. I think I will need to change the whole units to get black

Geo has nothing to do with corner weights.

Corner weight for 1 track day a year ! I have only ever corner weighted one car in 93 , my true track hack when I never took any one out in it ever.

I would do a track day and find out if you are better than the car already. Have you driven a PDK , e-diff, rws car yet ?

I like the satin platinum finish on the wheels, makes sense to get a geo check done, and get it to standard factory spec. Wasn't it done by the dealer when you bought it..?

Are you sure about that comment above Demon...? Having spent countless hours adjusting geometry and corner weighting, I can assure you the two are inseparable....when you adjust one, you alter the other, its a process of time consuming iteration to get to the settings you want.

If you want, go and wind the ride height of one corner of your car up or down by 5mm, and tell me the effect it's had on your geo, and then report back.....

[Adrian-9iafn]

I have set geometry up on many cars, 4-5 BMW M cars with adjustable dampers and several 911's. I ran a 964 RS for road an track for 10 years. I have done my fair share of track days in the past, UK and Europe. I have been to the ring and Spa on open pit many times. I am not professing to be a good driver but I can feel the difference in tracking, toe, ride heights, track etc. My current GTS was noticeably better after a geo set up. Not sure why some people feel that you should not bother with getting a car right if you only intend to do one of two or even no track days a year :eek

[Adrian-9iafn]

Ps yes I have driven a PDK, I have a 991.1 GTS with a geometry set up outside right now !

[Adrian-9iafn]

PPS, I have never owned a non RWS car apart from a golf GTI, since 1992 when I had a 911 SC, that had Bilsteins

Sounds good....I'd still suggest getting the settings back to standard, and driving it to see what you make of it before making any changes, at least then you'll know what you want the car to do differently, and be able to adjust it accordingly...

I know what it is and does, I just don't think it's worth corner weighting a road car.
So a geo is a geo and that’s that forget comer weighting for 1track day a year.

If you race and only ever go one up then yep corner weight helps in a number of ways, but running fuel to empty will screw up that £800 comer wight session, or taking some one out in your car !

Because you can have a geo without the expense of corner weighting !

We all know what a geo is , I am testing you :-)

I geo all my cars, but only ever corner weighted one from 93.

Any car that has adjustable spring platforms (like a 991 GT3) I would say needs corner weighting, particularly an older car which may have had some geometry adjustments in the past. A poorly corner weighted car will handle just as badly as a car with bad geo.

Fuel level drains reasonably evenly across the axle of the car, and its the side to side weight balance which is critical to a car's handling, not front to back (which will be affected by fuel level)

Not sure who charged you £800 for a corner weight session, but they saw you coming..!

Think he’s referring to RWDrive.... Not sure the 991.1 GT3 had RWSteer, but I may be wrong....

Nice car: congrats...!! Saw it at OPC Sutton today when mooching around.... Seriously considered it myself recently when looking for one— but have decided to be a sucker and pay overs on a Gen2..... It has an interesting spec: folding buckets but no “club sport pack”.... Otherwise, has a full on spec list (inc.PCCBs) and low miles..... A good buy for someone with a desire for the “Clubsport Feel”, without the full Roll Cage etc.... Nice choice....

[Adrian-9iafn]

Hi, yes the spec is great I drove a GT3 CS at Bristol in April, but decided against the CS for mostly road use. This was a nice specced white car with 6k miles, went quite quick. This car had black PDLS and I love the look on white, the car below

Oh yes sorry not owned a RWS car, I meant RWD

In this case a typo of RWD.

Regarding RWS, I know very little but I have read all the articles, collected them when the 991.1 was announced and read Elephant Racings useful review. I'm not a chassis expert, but love learning and do have a degree in automotive Engineering and did used to build F1 engines in the late 80's, including porting the heads on the DFZ's, so I'm not an idiot, well I don't think so.

It’s a very nice example..... Had a good nosey round it yesterday while I was there (and then red-lined it a few times.....!! JOKING.....!!).

If I could just have forced myself to like flappy paddle shifts (the Porsche PDK-S box is the best in the world, after all), it may well have been the car for me when I was looking at them last month.... Alas, I’m a die-hard manual guy, and nothing is gonna change my mind..... So paying stupid overs on a Gen2 GT3 it is for me....!! Coming from an F1 background, I imagine you have a different perspective on the PDK transmission....
