Difference between 4.5 Lightweight vs 'Normal' 4.5 Cerbera
Discussion
what i meant was that the Light Weight cars most of them were fully loaded eg.red rose,4.5 full leather,heated screen etc. So 1079 i could really do with the first number before the 'B' but i will go with standard 4.5 Silver Stardust on line 17/03/2000 ????

Thanks for the info nemasis, fascinating stuff. Can you clarify what you mean by the bit in bold above? Any juicy gossip for my "LW", B001079?
I would be interested in a genuine discussion about what a red rose actually was.
There have been a great many threads on this over the years I have been on this forum.
There have been red roses taken apart for rebuilds where there has been obvious porting, and some where there has been no obvious differences to everyday 4.5s
There have been instances where people have said blueprinted, and others where subsequent blueprinting of the bottom end has shown no initial work done.
So apart from the obvious button and dual map, what actually was a red rose?
Strangely when I took a 4.5 apart there were a number blind end drill holes in the balance weights on the crankshaft. I assume that meant someone tried to balance the crank, Its a boggo 4.5.

Hi, the extenders were fitted to the chassis after we had problems with the standard shock absorbers, PW drove a car and was concerned about the car nose diving,the result were upgraded shock absorbers that were not the same size as the standard ones and at that time they didnt do uprated in the size we were using, so hey presto in true TVR manner knock up some extenders and the bigger shock absorbers fit.These were fitted until the shock manufacturers made some shocks to our spec and the chassis were changed to accomodate.

My cerb is a late '97 4.5. It had these suspension mounts...
I have now fitted a 2002 chassis and the damper mounts stick out further than the above. So another difference between the older cars and the newer 'LW' is revised suspension geometry.

Some more of the id is B12A3YB001079 but mine is a STD 4.5 silver stardust as described. I think it's full leather but hard to tell.FWIW I thought there were comparatively few red rose cars, ie no more than about 10% or 15% of the post-2000 run. Would be interesting to know how many are out there. I know some were done as a retrofit.

My RR has been apart and all the stuff listed etc was done to it as per the RR sales patter. Sadly it was done badly hence taking it apart and doing it properly. There have been a great many threads on this over the years I have been on this forum.

if i remember all the later 'T' cars were all vinylester or core mat,rather than GRP and i dont remember ever doing light weight versions of 'T' cars, i was looking through the paperwork and i have the original spec changes of what exactly went on 'Red Rose' cars from cerb,tusc,tam,T350 if i get time i will type it out.

Great thread - very interesting reading and I don't even own a Cerb ! Nemasis, do you have any nuggets of info regarding any other TVR's - for example did the red rose T350's truly have a lighter weight body - vinylester used on certain panels giving a reported 40kg saving ?
The 4.5 LW has a much lighter bonnet than my 4.5, met up with a new cerbera owner the other day to compare cars, lifted my bonnet as usual with a fair amount of force as its heavy, did the same with his bonnet and nearly ripped it off the car, it was atleast 2/3 lighter than my bonnet.

i have it down as 1402 silver stardust 4.5 thats it,on line 08/09/2000. Not Light Weight.

I've just sold B12A6YB001402, which was sold to me as a 4.5LW - i presume it's not really a true LW as it weighed in at 1185kg with about 20L of fuel in it.
Spot on, actually registered on 1/10/2000; i better get our weighbridge calibrated, as it does appear to be a bit light compared to others

Ours is an early GT car that I got excited about for 5mins too. Those spacers may have been put there just to fit a different shock, it sounds like TVR alright! But they apparently have a nice side effect. Mouting the coil over more upright changes the ratio of wheel travel to shock movement, giving I’m told better control from the shocks. markh1 said:

Another difference was outlined in sprint a few months ago, it said the front uprights were designed to work with two piece discs like the early GT cars had, these have very thick alloy centres, when TVR changed to the cheaper later single units the front wheel offset was messed up (reduced) The all steel discs were a lot thinner so the scrub radius was then wrong. You can buy now buy spacers to take the wheel out to the original offset, unsurprisingly the people selling them said they make a huge difference, but they weren’t too much to find out for your self. I didn’t pay much attention to who was selling as I’ve already got thick bells(!)
