Driving CarreraLightweightRacing's 996 'CLR' (briefly)

Is that a RHD issue - I have not driven a 996 in a long time, but don't remember anything untowards. Recently sat in a 996.1 GT3 in a showroom and felt very good. Might have to have another closer look before buying one - a crappy driving position would clearly not be ideal ....

[Diesel Meister]

1. compact, well balanced and responsive chassis
2. naturally aspirated, free-breathing and zingy engine
3. low hip-point / seating position (buckets!)
4. spanish box (positive but well-oiled and brief of throw)
5. unfiltered / assisted steering

I think there are a few cars that could fulfill this brief, mainly between the 986/996 and up to the 981 Cayman (987/997 in between possibly).

I'm salivating at the prospect. I honestly think that, unless you really want a newer and/or mid-engined car, you won't find a better base than 996 though. Attainable at present and ripe for a bit of CLR-type treatment

ah got it, thanks. yes, the normal seats are not great

Richard/ CLR is an absolute gent, gave him a ring earlier this week and aired my idea of a similar approach with a 996 Turbo.

Hopefully it will become a reality, Ive already sorted a donor car

Can I ask you how much of a pain it was to 'eintragen' all these things?

Especially the steering wheel interests me, as I am 6'7" tall and am toying with the idea of a 986/996, and I'd love it if the steering wheel could be moved a lot closer to me (for leg room).

Hi NAS, it is a major faff getting all of this TUV approved. Very expensive, but once done, having these CLR's meet TUV approval will at least show the engineering integrity of the project meets very stringent guidelines. I can consulted with the inspector every step of the way so that when finished, I shouldn't have any issues getting it approved.

On your other point, try a dash delete first, many tall drivers say it really helps. The CUP steering wheel also comes with an additional spacer ring to bring it even closer to the driver. I never fitted this though as it would be a bit of a stretch to indicate

Thanks for the info.

I'd be very happy with that steering set up. The whole car appreals but think i'd prefer a different spring damper set up, lots of camber everywhere, super sharp and it sitting as low as i could get it without scraping the floor off of it on B roads.

Absolutely spiffing! Thats the joy of a car bit to this spec. it's a lovely light blank canvass that you can easily set up to your own specific requirements. Absolute hoot on the road at any speed. A propper driving tool without the need to achieve warp speeds to enjoy it.

Cmoose bangs on about Posche producing a car like this regularly and I agree completely. No need for the frankly rediculous 991R. Just make a cooking C2, take all of the weight out of it and throw away the active systems (after killing the team that designed them of course). Give everyone a chance to drive a car that feels like it has a little bit of humanity built into it..

Fully with you Steve and absolutely understand where you are coming from. The difference here is this car is designed as 'fast road' rather than out and out track. There is enough adjustability with the Ohlins R&T to suit most situations though. But perhaps something you may not have considered is that the car will be about 17.8% lighter than stock so this will have a similar effect in terms of how the dampers behave; effectively about 18% stiffer. I have spoken to BG-Motorsport in Silverstone and they have said that the R&T designed, for a car 250kg heavier than my CLR, should make for an excellent handling package. Ohlins headquarters over at the Nurburgring also mentioned than a 15% increase in stiffness for the R&T would make the car far more suitable for track; so again, effectively bang on target for what I have in mind.
So my feelings are that Ohlins R&T in the CLR, should provide a perfect balance. When I have finished building the car, you'll have to pop over and try it in it's natural environment; can also throw in an evening session at the NBR GP circuit just to see it you also think it performs adequately on track; it may surprise you
I'll also be picking your brain with regards to geo settings nearer the time; so don't say I didn't warn you

Many thanks for the kind words Axel, I look forward to working on both of the cars you want me to ruin for you

A proper bucket seat in a 986 makes a huge difference - really makes it feel much more of a sports car.

I thought the question was appropriate and framed fairly tactfully TBH.

[CarreraLightweightRacing]

Need a little favour guys; had these arrive this week but want to get a set of adjustable pillow ball top mounts made for them. The company doing this need a stock rear top mount for a 996. Does anyone have one lying around that I could use. Condition pretty irrelevant as it will only be used for taking measurements:

[Diesel Meister]

I cannot help sadly but I felt compelled to post purely to underline the drool-worthy nature of those struts!

What's the spec?

[CarreraLightweightRacing]

They have 20 click settings on the rebound for driving ranges:
- 0-7 clicks for Track
- 5-10 clicks Fast road
- 10-20 clicks Road

Ride hide is 20mm lower than stock with +/-15mm adjustment range.
They also come with DFV (Dual Flow Valve) which really helps on the compliance front to smooth out rough road surfaces.
Spring preload can be adjusted...

I don't intend on the car being a track car, so having the scope to dial in some road manners at the turn of a knob made me go for these. Also with the car expected to be around 250kg lighter than stock when finished, these should be just about the perfect match as I've been informed the R&T are around 15% softer than optimum.

[Orangecurry]

I think I love them.

[CarreraLightweightRacing]

Orangecurry I suffer the same sad affliction as yourself regarding inanimate objects

As per my last post has anyone managed to find an old rear Top mount for a 996?

How do you make 981 steering manual?

Any update on the CLR project.

Any update on the CLR project.

Hi G, a bit manic right now as the last phase of this project is all go. On target for a 1086kg final weight (dry). In the process of redesigning all the suspension parts, all the carbon panels are in production; in fact some are due to arrive today (Ducktail, front wings and bonnet). Carbon doors, door cards & mirrors another 3 weeks or so. Throttle being re-bored... But here are a few pics of some bit and pieces since the last update:

Suspension all fitted (I am currently redesigning the lower wishbone though so will change this soon):










Inconel625 exhaust with Carbon tips (20.6kg reduction for this):





T6061 forged wheels:




Carbon/leather seats (Custom made seat rails which also allow access to the rear) and some titanium wheel bolts:

As I removed the pax airbag this leaves a useful sized space behind this panel being wasted:



After a bit of work with the Dremel making the opening a bit more user friendly, I now have a glovebox. Still early stages and needs a little tidying up but you get the idea:


And closed again.


Still a lot more to come and am aiming to finish by April

thank you for the update - looking great
one of the most entertaining threads on here nowadays

Can't see how you'll get that in Rich ? But what's more, it hardly fits in with the whole lightweight ethos you're chasing. Worse still that magnolia will clash horrendously.....

Would be interested to hear about your "custom made seat rails which also allow access to the rear". Quite surprised someone hasn't come up with a good solution to make buckets tilt or slide allowing enough access for rear seat passengers.

Main concern would be how much space these would allow rear seat passengers if they had to get out in a hurry after an accident.

Carbon Ducktail, Bonnet and Wings turned up today:

Good call H maybe I got a bit carried away going down the Singer route with the leather quilted chaise-lounge with deep shag polar bear carpet combo

Seats were a major faff to get right. I had a few issues and had certain key objectives:

1. I needed rear access for a few reasons: to make rear suspension adjustments, to retain the practicality of having 4 seats.
2. Due to fitting a CUP steering wheel the gauges were obscured. I needed to fit the seats in such a way as to alleviate this problem.
3. Keep weight to a minimum. I managed to remove 24.6kg with the seats.

I also made them taking my own anthropometric measurements into consideration. I'm 5'10" and around 80kg, so I basically made the rails in such a way to maximise the forward travel. If someone was 6'5" I would basically have to accept that only the passenger side seat would allow in/egress of an adult. Children under 12 would still be fine on either side. A few pics of the fabrication process including the little jig I made to get the correct fitment:
