TVR Cerbera - Production run mods

Early Cars	Later Cars

These new pictures were taken with a video camera so the quality is not up to usual standards.










	Waterproof covers over door entry buttons

	Strengthened Anti Roll Bar Mounts

	These 3 holes are drilled in each side of the boot floor when the 'double bubble' door seals are fitted
Under view of sump	Later cars have one large drain plug on the side of the sump where it is protected from danger. The strengthening brace is now also integral with the sump.

The first headlamp bezels were a bulbous plastic moulded affair. When TVR started making them for themselves out of glass fibre they lost their bulbousness & were glued on with the same adhesive used to bond the windscreen in. However, if a repair was required it was impossible to remove it without damage. The later bezels are fitted with 4 nuts onto studs bonded into the bezel its self.	Heated rear window & air-con switch now have a white printed legend on them. Screen vents have increased in diameter from 8 mm to x mm There is a modification on the way for the crank pulley.
The original system used a courtesy light switch from the VW range.	The modified door pin switch is now a magnetic proximity device with a magnet bonded into the cill. There is a retro fit kit available from your dealers.
Note the lack of the cubby hole	The top inner screen rail now has the interior light on the horizontal plane rather than vertical and is a little less deep, meaning that the view out of the windscreen is a little less letter box sized. The door seals are now deeper around where the window closes. They are about to make the rest of the seal into a figure 8 section rather than an O section. What Peter was saying to me at Croft has finally happened. The centre 'penny' air vents have now gone. There is an additional eyeball vent in the drivers footwell and both that & the centre face level vent only supply cold air. Hot air is now only available from the screen holes & the transmission tunnel 'pennies'.
Boot light switch on offside.	Now near petrol filler cap.
Air con pipes from compressor often fractured due to vibration.	Certainly > VIN 1777 the pipes have a piece of aluminium welded between the two pipes.
Air conditioning flaps were solenoid controlled. A much better idea in my mind which is why I got hold of some to retro fit to mine.	Now aluminium discs on a piece of piano hinge.
Door release, central locking and window buttons did not have LED warnings to indicate their position.	They do now. You can convert the door & central lock buttons yourself. The buttons are RS part no. 184 - 9165. Remember to use a 680 ohm resistor to drop the voltage to a safe level for the LED.
A-post covers and rear window hold-in strip were made from plain	They are now made from carbon fibre. They are a bugger to get off. I know, I've seen it but it is possible to retro fit. I had the A post covers upgraded at the factory before I took delivery but my rear window strip is still plain black Fibreglass.
Front hub carriers were machined alloy and had separate bolt on caliper mounting brackets.	Later cars now use a cast upright with an integral bracket.
Early cars had an extra centre silencer.	Long since removed along with a rubber bobbin which held it to the skid plate.
Early cars had a propshaft with rubber bushings but the torque proved too much and they began to rip.
Fan & fog lamp buttons were plain.	They now have legends printed on.
The air conditioning condenser was riveted to the radiator which meant that if the core needed replacing, as I found out, the air-con needs to be bled and re-filled which costs about �135.	Later cars ( certainly > 1229 ) the condenser is bolted to the body.
Chassis numbers were stamped on the front cross member	The can now be found inside the offside front wishbone mount

Miscellaneous notes I haven't found a category for yet

Post Jan 97 vehicles have Mk II windscreens - More return to A posts

Rubber finisher at the top too. Rear screen also has a rubber finisher at the top & sides.

The later car the better, as TVR are on Cerbera v1.09 at the moment apparently.

Can anyone confirm this?

Want to change the wheels ? PCD is 114.3mm. Offset or ET is 35mm.

Centre bore diameter is 71.5mm.

The chassis are now coated with a white powder finish not silver

Early 1997

Speedometers now read upto 210 mph plus a notch, which would be 220. Also 360 km/h marked on the inside scale.

Cill kick plates now a �62 option.

July 1997

Brake bleed nipples now have rubber covers.

Wheel nuts are of a different style.

July 1997

Boot light switch is now on the nearside.

July 1997

Early cars had a number of body items which were moulded separately and bolted or glued in place.

These included :

Separate fibreglass front number plate mounting spar
Separate indicator nacelles
Separate rear bumper overrider

Note the plastic headlamp bezels & the sealing rim around the lens

These are now moulded as part of the main body.

TVR have now started using Bridgestone SO2's with the rears changing to 245/45 x 16".

All Cerebra's will be fitted with a strengthened steering wheel mounting boss. It is not being classed as a recall and will probably be done at the vehicles next service. They need the old ones back at the factory to modify them and send back out as the modified version.

June 1997

The ECU code number is written in black marker pen on the ECU lid. This can be found behind the passenger toeboard carpet in the footwell.

Code	Problem Description
242	Bag of spanners when cold
271	Propensity to put up spurious fault codes
273	Much better when cold

Stereo system change from chassis number 1348

The system does away with the door mounted high frequency units, the rear midrange units and the large central full range speaker. It will be replaced with a more conventional four speaker system, with a full range speaker in each door and in each of the rear panels where the mids are currently located. The crossover is no longer required. Replacement panels and wiring looms are available should you wish to retrofit.
