Hello all,
I bought a Cerbera 4,2 last year which is currently in for a rebuild.
Keeping it at 4,2 which is fine for an old fart like me BUT I'm wondering how stable they are at higher speeds.
I also have a Tuscan convertible which was pretty scary at around 120mph on the Autobahn. Having the small winglets fitted sorted that out very well.
I'm selling my CLS to pay for the rebuild and the Cerbera will, for a year or two, become my daily.
So, I'm now, in excited anticipation, wondering what my Cerb will be like on the Abahn?
Please share your opinions.
Apart from the engine job, the previous owner spent significantly on suspension, shocks etc and much other stuff (thank you).
I'm aching to get it out but am currently exercising my TVR patience.

Once I replaced all the suspension bushes the Cerb became perfectly stable at any speed.

A set of freshly balanced wheels makes a massive difference too.

With a decent suspension set up the worlds your oyster, I've had my Cerb up to 185 and been totally happy. I'll grant when I've had a previous subtle wheel balance issue it felt horrible above 70 too.

bottom line if it's set up properly then a Cerb is fine at high speed, I think some of the issues seen can just be you hanging onto the steering wheel too tight (white knuckles) as the quick speed rack can have you change two lanes in a sneeze, relax....

Mine felt perfectly stable at 140mph.. Make sure your suspension is all good and you still have the under chin spoiler.

my old 4.5 was rock solid at speed, in fact I saw just north of 180 on the clock (on a perfectly legal location of course......) and only lifted off as the bonnet started to flap wildly due to bad adjustment on the latches.

Great, thanks for the advice and thumbs up.
Under chin spoiler? scratchchin No idea, I'll have to check that.

My Tuscan is a 2006 with the slower rack.
front end used to go very light but with the winglets its fine.
My previous Mk1 was fine after geometry, new shocks and wheels were done.

Anyway, very excited to be close to getting to know my Cerb.

Thanks again.

I had 2 Mk 1 Tuscan's in past, both scarey as hell at high speed. I once did an indicated 174mph on an airfield track day, felt like it was about to go very wrong any minute. Front end felt like it was going to take off! I had the spacers fitted which made it less twitchy in general but it never filled me with confidence at any speed.

My 2004 4.2 Cerbera is totally different. Granted it has Nitrons and has been properly set up, but boy it's a totally different proposition. So solid at 'normal' speeds compared with the Tuscan. I've had it up to around 160 and it felt totally stable. I'd say you'll be fine if you have full geo set up and decent aftermarket shocks

Yes, I had my Mk1 done with geo set up, new shocks and SP12 alloys which dont need the spacers. With all that done it was great.
The Mk2 has had the shocks changed and has SP12 from my Mk1 (which I killed unfortunately). but its been the winglets that have kept the front wheels on the road.
Th Cerbera has got new Notrons on and I'll be discussing the geo after the engines sorted.

All very interesting and good to hear the good reports on the Cerbera stability. thumbup

Hi Tony,

The new Nitrons were fitted along side a new set of tyres (fully balanced) and a full geo. The wheels were also brand new. She was very stable at 120 but didn't go any higher. No chin spoiler fitted though so maybe that would be a good idea if you're going to have fun abroad!!

Oh and the air con system cost me a fortune to sort so that can be enjoyed whilst the sweat is dripping at 150+ cool

Very disappointing to hear it requires a rebuild. I felt it ran fantastic but it was the only Cerb I'd driven so hard to compare.

Catch up again soon

Steve

Hi Steve, please don't get me wrong, I'm not complaining about the rebuild at all.
I was aiming to use it to commute to Germany but Ian told me it needed a top end job and that should get that done first. I've decided to get the full rebuild.
You did a great job bringing the Cerb up to the great condition it's in.
I've got that fat file full of all the receipts and details of the work you did.
I'm itching to get it back.
Maybe I should buy that T350 off you when it's sorted laugh

Chin spoiler keeps the wind from getting into the engine bay from underneath and causing the steering to go light.
Other than that, with a well maintained car, it'll be fine.

(time for that pic again) biggrin

Always found mine sitting nicely at speed (solid at 140) however I always found that on the road long sweeping bends would make me nervous even on bumpy motorways.

Ive recently got hold of a very subtle rear lip spoiler... Im waiting to fit and run on the car before I give too much away but Im hoping that will add confidence and keep the rear pinned down.

Alistair, do you have a picture?
I always thought a spoiler that was integrated into the bootlid would be nice.

I've always liked the way the back slopes nicely down as it leaves the car. I've not found the aero to be that bad, and to be honest, even on trackdays/autobahn I've not found issues. My suspensions set quite soft as I like the comfy ride.

How about tyre pressures, ride height, etc
and some gratuitous photos of the rear end, just because

Pictures to come soon Aide, next time Im at Powers I'll offer it against the car as position will be key. To get your imagination working think like the tiny lip on the later Tuscans that were blended into the boot.
