Nordic Flyer

Hi all,

My first post on the forum, have been following for a long time though.

Live in Scandinavia and been through a number of 911's and lastly a GT4 that I liked very much but offered me restricted usage in terms of ground clerance as daily driver.

So, as mentioned I have a Turbo S incoming in February. Easy build in Carrera White with bucket seats, no sunroof and not much gadgets actually.
Rear sets to be removed and half roll cage to be installed by dealer. I will track the car extensively and have a set of Forgeline 20" GE1R on the way in Pearl Grey on which I will put Cup 2 tires.

The car will be used all year around, hence I will have winter tires.

I have no plans to do other mods at the moment, maybe later.

A question for you:
To take out some understeer, will 265 (Cup2) be OK in the front? Rims are 9x20F (12x20R btw).

Thanks!

They will fit, but the diameter is increased, so you will probably need to also change to 325/20 rear. Karl911 runs this setup.

My only concern, and why I've held out, is that the 265 will be much wider than the rim, so there will be more overhang of the tire beyond the edge of the rim, which may induce sidewall instability or flex, possibly negating any advantage at all. If you can find somebody to make you 9.5 inch wheels that will clear, that would be much better setup.

The other choice for more grip is Trofeo R in the OEM size. They do grip better, but don't last as long, meaning more expensive.

Are you also installing a 6-point harness? European cars come with seats to accept harnesses. In the US, we don't have the seatbelt pass throughs!!! I had to change to Cobra Misano seats.

Question for you Nordic Flyer, even with the 5" of ground clearance some chunks of ice will be encountered, especially where the plows cross streets and leave debris. Besides the obvious paint protection film, any insights on how to be sure to not bang up the front end?

I always planned to drive on cold clear days and leave the car home when the roads are salty or messy, but l'm finding myself driving the SUV everywhere while the car stays parked. The ice chunk concern is part of the reason.

Randy, yes 325 rear could be a choice, however, will understeer then be taken out somewhat? Rear grip will increase so I guess the balance in the car will remain as stock??

Trofeos in 245's is for sure a tire to consider, no experience with it so far. Did you try it? I heard durability and wet grip is less than Cups2's.

I will have the 6 point harness.

When heavy snow fall occur I leave my P-car in the garage and use my SUV. No reason to risk damage to the car. 911 is a wonderful winter drive though:

Dang, I was hoping for a pearl of wisdom from the north! Thanks!

I used to live out in Finland (puhuinkin suomen kieltä) - beautiful area of the world up there!

Nordic Flyer rocks! I've been threatening to a) track my TTS and b) put snows on it and drive it all year round...and after a whole bunch of 911's - never did either (except with my GT3 that went on the track)...and Nordic Flyer orders a car, puts a half cage and snow tires - awesome....damn the torpedos! I have to rethink why I buy these cars.

Nordic Flyer

Yes, why not
I want to get as much fun as possible out of this car no matter dry summer or cold winter.

I would try first changing suspension settings and experiment with tire pressures to reduce understeer, you can get rid of all of it most likely, that's a very economical option.

If nothing else works 265 front will help, but I would not go wider or taller in the rear, it will negate the balance impact again. The rolling radius change is not enough to worry about it for the diff.

Try maximizing camber in the front with the stock setup
Higher tire pressure Front or Lower rear

I assume you don't want wider tires on snow

I was in 6" recently without issue...

Great, what tires are you on?

This is great advice. Nordic - have you driven the 991.2 extensively yet? The reason I ask is because the rear wheel steering gets the car to rotate a lot better compared to previous gen models. For example I have a 2011 Turbo S that I track along with my 2015 Turbo S. The 2011 is the 997 chassis and it took a bit of tweaking including as much neg camber in the front to get the car to rotate and not push so much. Whereas with the 991 chassis with the rear wheel steering, I find that the car is much easier to rotate in corners. Now it does push a little but a look at the stance from the factory - the front wheels stand straight up (no camber at all). So a simple fix is to get a performance alignment to max out neg camber in front and combined with the rear wheel steering, you may find this suitable. Good luck.

Thanks for advise, this seems to be a reasonable way to start.
Never drove a RWS car, so this will be a new experience for me.

I still haven't got my car, will arrive end Feb.

One of the best pictures I have seen on Rennlist. Where is this taken?
