I presume this will be a two seater a) because this is a lightweight project and b) you have a Ti cage that will get fitted.
If so, why do the new CF panels have the rear seat moldings instead of a parcel shelf? Is it for strength or do you want the option to fit kids in the rear when there is no cage fitted?

More 911 K carbon fibre porn :














It’s been close on 15 years since I last visited Tuthills and met Richard.
What a transformation, a deeply impressive set up producing some stunning cars.
Of note was this ready for collection (it was at the BH Scramble yesterday) :





Tuthill are also producing a run of SCRS restomods based on the 993 platform.
Two cars were undergoing final shakedown/prep, a stunning dark purple metallic car and an equally stunning Mexico blue example.

Whilst I was there, a member of staff went to collect the owner of the Mexico blue car from Banbury station. His “taxi” was to be the gold 911K, which was fired up in the workshop before driving off. I have a 30 second clip, it’s quite something smile

Both the Mexico blue and dark metallic purple SCRS restomod builds were at Bicester Scramble yesterday, along with this Mint green example :



This is the engine bay of the Mexico blue car









Apologies for gently de-railing your thread Andrew, but it’s all Tuthill porn and shows just what they’re up to (and the quality of it) in their lair in Wardlington.
As others have said, looking forward to further updates on your build.

It is just how the bulkheads are, but no plans to use the spaces are seats - as you rightly point out, there will be a cage back there anyway. The area will be trimmed and there will be plenty of carbon poking through too.

As derailings go, that’s a good one Slippy thumbup

Did the gold 911K have the production exhaust, did they say?

I think (and I stress think) not Andrew. I’m pretty sure David said they were still developing the system further.
The current system was pleasingly loud smile especially in the confines of the workshop ...
But even once outside it sounded wonderful as it drove off (though not ridiculously strident)
It’s a shame the speed ramps on the driveway up to Tuthills are so vicious, as I’m sure there’d have been a good opportunity to demonstrate the sound of the exhaust admirably, though no doubt to the chagrin of the locals ... biggrin

Tuthill have done a phenomenal job in developing what should be an amazing and entertaining car to drive. It has all the makings of being a very special car indeed, I hope you enjoy it smile

Keen to hear the new exhaust and also drive the car again as a lot has been done to it in the meantime.

I’d love to know how much of the wheel and tyre spec on this car is looks rather than need. ST’s in period were 250 to 270 bhp and very light….so with modern compound ubber and more weight in the car I’d have thought if anything they could have narrower/lighter wheels than an ST ran. Less might be more.

Have you ever driven a st with 270bhp and lightweight,you need all the grip you can get,especially when wet or against a clock.Looks great also with the arches properly filled out.

No.If I had I might not have asked the question. I said above “how much of the wheel and tyres spec on this car is looks rather than need” ?
This car is probably 150 to 200kg more than an ST would have been in period with modern rubber. Yes it’ll have more power but the extra weight and rubber make a huge difference.

I'm glad someone asked this question, as I have a 246bhp rear engined car that weighs ~980kg, and I'm considering preferred tyre and wheel specs.

There's a good video here on whether wider tyres offer more grip

The upshot seems to be that in the dry wide = good, but in the wet you want narrower tyres. There's another good video there discussing profiles and driving performance of 17", 18" & 19" tyres.

AndrewD (or anyone else) - Do we know dimensions of the wheels and tyres proposed for the 911k?

Probably only a 205 and a 215/225 on the blue car… with far sidewalls. Not overtyred and a perfect figment.

Front 7 x 15 Rear 9x 15. They have carbon rims, so they’ll be as light as a feather, I imagine the 7 x 15 fronts will weigh no more than 4.5kg, and the 9 x 15 rears 5.25-5.75kg ...

Edit to add, the whole wheel set weighs 19.8kg according to Tuthill’s website. So the above was a reasonable guess smile

For comparison, one 12” x 19 997.1 GT3 rear wheel weighs 14.5kg ...

That blue ST rep is on historic racing rubber by the looks of it. How grippy are those these days compared to the past?

My guess would be that car is not overtyred.
