look forward to seeing more pics.Pappagallo said:

For example the front bumper alone came in at 45kg (complete) the carbon one weighs 6kg and very similar for the rear.
Things like bumper reinforcements and brackets etc all add up (no longer required)
So, err, are you saying you've removed the front and rear bumper beams and other parts of your crash structure?Things like bumper reinforcements and brackets etc all add up (no longer required)
Audi don't make bumpers that weigh 45kg for fun. You can't just replace that with 6kg of carbon fibre. You can replace the Audi bumper SKIN, which probably weighs 6-10kg, with 6kg of carbon fibre, yes. But that other 35kg or so is NEEDED. You WILL find this out when somebody nudges you and, instead of dinging the removable crash bar, the monocoque itself gets tweaked.
Either you're drastically misunderstanding the weight that's been saved, or there's a game of russian roulette being played with your car here. And all to save less than the weight of a tank of fuel on a car that's still a ton and a half and - let's be honest - does not really NEED every last kilo to be shaved for power-to-weight reasons...

sorry , but that body kit cheapens the hell out of the R8
should probably rename the thread "How to make an R8 V10 look like a MR2
Almost everything you comment is negative and/or downgrading. Just because you don't like it, that doesn't mean it's true. I, for one, like that bodykit on the R8.should probably rename the thread "How to make an R8 V10 look like a MR2
OP, keep updating this thread, I'll be watching with interest

...wait, you shaved 275kg off of it without removing the interior and plan to get another 200kg out of it?...do you mean lbs not kg?
I cant believe there is that much fat in the car?!
If you have time I'd love to know how you shaved 275kg off of it.
The Spyder weighs in at 1.7t.I cant believe there is that much fat in the car?!

All sound deadening has been removed, splash guards, the standard bonnet also weighed more than 3 times what the Carbon one does, the exhaust saved 35kg alone.
The wheels are forged and weight in a 9kg lighter per corner.
The list goes on, pretty anything i could remove i have and i am still doing so.
However, like Tobylarohn has said above, I';m not too sure on those weight numbers
The standard wheels weigh in at 11.2kg's each, so not sure you'll get 9kgs out of that unless you fit the car on casters.
Likewise for the exhaust system. A standard R8V10 system weighs in at 42kgs, which admittedly is a heavy old lump for such a compact exhaust, but even a titanium Akrapovic system only shaves 16.2kgs from that.
Had you considered taking the roof mechanism and system off as if you're not using it as an everyday car, it's probably not needed and weighs in at a massive old lump very high up in the COGrav consideration ?
Love the body kit though and looking forward to seeing it done
Keep the posts coming
I’ve read all the good "constructive” posts so thanks guys.
As for the plain SILLY negatives.
Things like the bumper reinforcement bars etc will all be refitted(they are ALLOY) so weigh next to nothing.
Life would be a boring place if we are all the same, I have built plenty quick capable cars over the years so I am no idiot, I’m also a qualified panel beater (years gone by) so bodywork you could say is my thing.
For the comments about a “bodykit” don’t be silly, the work that has went into each and individual panel to lighten and make even stronger than factory has been a huge task.
What your seeing is work in progress pictures and so far we are talking 100s of hours have went into the car and purely on my own.
I move the goal posts daily and try and constantly improve and tweak, the proof will be in the pudding as I have some good lap times and also ¼ miles when the car was standard to compare against.
One thing that hasn’t been compromised is safety and that is also reflected in things like the new seat set up, plumped in fire extinguishers etc, bare I mind I drive this car every day too and covered 23k miles last year in it.
More pics soon.

Then I definitely call custard on your bumper weight saving. It sounds like all that's being replaced is the bumper skin. If you really ARE a "qualified"(?) panel beater, then you'll know how little the plastic skin weighs, and that all the weight is in the crash structure.TooMany2cvs said:

Are you actually being serious? The standard bumper/bumpers are made of "multiple" parts and most of it heavy plastic trims and so on and more brackets that you can imagine, i am fairly comfident you probbaly have never stripped an R8 front or rear end and actually seen just how much plastic crap is hidden (not needed or can be changed)
Without sounding pedantic, I am delighted with what I am saving and in my mind will help with my goals for the car.
The "Alloy" "crash Structure" is separate to the bumpers.
I am fitting a one piece carbon fibre bumpers which includes all mounts (also carbon), what’s more to explain?

This is going to be great! Think its awesome that you are able to modify/adapt/rebuild a car that many would not have the nerve to modify! Good luck and definitely keep us updated with progress!
Ignore the people who have nothing good to say, amazes me that they even bother posting, just go and look at another thread!!

I too am doubtful about the weight saving, no doubt it'll be much lighter but half a ton? That's a very tall order. Are you sure about the 9kg per corner weight saving from the wheel change? As far as I'm aware the stock wheels are 10/11kg as is.
Still, I think it looks great and I'm really interested to see how much weight you do end up saving!
