As to the quality of parts for Kit 1, looking at that proposed kit, I would suggest as follows:

One-Piece Forged Magnesium Wheels - to be desined and made by BBS Racing (the supplier of 918 magnesiujm wheels) and, as such, better than OE and lighter

Lightweight Alternator - better than OE and lighter

Lightweight Starter - at least equal to OE and lighter

DR-25 (M Spec) Wiring Harness - better wire and better connectors than OE and lighter

Lightweight Specialty Alloy Rear Axles with 10 Ceramic Ball CVs - better than OE and lighter

Carbon Fiber Retractable Rear Spoiler - better than OE and lighter

Carbon Fiber Induction System - at least equal to OE and lighter

Carbon Fiber Oil Tank - at least equal to OE and lighter

Lightweight Hoses - better than OE and lighter

Aluminum Metal Matrix Composite Engine Pulleys - at least equal to OE and lighter

Wire Electro-Discharge Machined Specialty Alloy Transmission Output Flanges - better than OE and lighter

Titanium Suspension Springs - better than OE and lighter

Carbon Fiber Anti Roll Bars - at least equal to OE and lighter

Full Titanium Exhaust - at least equal to OE and lighter

Titanium Front Hood and Engine Compartment Lid Hinges - better than OE and lighter

And, of course, much of the above will fit GT3 and GT3 RS.

Anyone know the weight of the Ruf SCR 4.2 that was shown at the Geneva show?

Robert Linton

Ruf website says 1190 kg = 2618 lbs. Not clear if that if wet or dry. In any event, I like the look of the 964 far better without the Ruf front and rear bumpers. Indeed, as a dream, I would like a 2000 lbs 964 with a 500 HP normally aspirated air cooled engine.

C.J. Ichiban

Well I have a few 964s that I would like to throw in your 500hp engine too!

+964

Nizer

+1928

Candidly, we will run the revised 2-valve engine in a few weeks. The 4-valve head is already in design.

Robert Linton

I have now received the alternator and the starter used in the R/RS and there is significant weight saving oppotunity there.

Robert Linton

This evening I spent some time looking at complete titanium exhaust systems for the R. In short, they are quite good, far better than I expected, and should save approximately 10kg. Additionally, I have asked if it was possible to make a thin wall version, which would save yet additional weight.

Robert Linton

No one has commented in some time, but I am confident that several hundred pounds can be taken off the car.

C.J. Ichiban

robert what do you think kit 1 will be worth weight wise? and will this be a DIY kit package?

Nizer

Don't worry, we're all waiting and watching intently....

Robert Linton

I estimate Kit 1 would save between 110 lbs and 125 lbs. Though I never thouight of it as DIY, below are the potential parts with the ones that could be, potentially, so marked:

One-Piece Forged Magnesium Wheels - DIY

Lightweight Alternator - possible DIY but better a shop

Lightweight Starter - possible DIY but better a shop

DR-25 (M Spec) Wiring Harness - shop

Lightweight Specialty Alloy Rear Axles with 10 Ceramic Ball CVs - possible DIY but better a shop

Carbon Fiber Retractable Rear Spoiler - shop

Carbon Fiber Induction System - possible DIY but better a shop

Carbon Fiber Oil Tank - possible DIY but better a shop

Lightweight Hoses - possible DIY but better a shop

Aluminum Metal Matrix Composite Engine Pulleys - possible DIY but better a shop

Wire Electro-Discharge Machined Specialty Alloy Transmission Output Flanges - possible DIY but better a shop

Titanium Suspension Springs - possible DIY but better a shop

Carbon Fiber Anti Roll Bars - possible DIY but better a shop

Full Titanium Exhaust - possible DIY but better a shop

Titanium Front Hood and Engine Compartment Lid Hinges - possible DIY but better a shop

Candidly, much depends upon how good a mechanic one is, the level of tools and access to such information as bolt torque you have. If it were me, I would have a porofessional do everything.

Finally, for Kit 1, I am looking into the possibility of a carbon clutch that might save another 10 or so pounds of rotating weight.

Robert Linton

The more I think of it, the more a carbon carbon clutch should be included with Kit 1.

Also, as I think about exhausts, perhaps, depending upon the component, titanium, inconel and/or 321 stainless could be be included in some combination.

Nizer

Any option for GT3/RS automatic?
