I have been working on the rear body of my GTT over the last few days.
The rear end represents the last BIG design concern I have on the car as I couldn't decide exactly how it should look.
Can't wait to be in Grabers position with finished moulds.

Very nice!

It is starting to look the part and will have the go to with that engine!

I love the front and sides looks so good! But the back end does need something, needs to be slightly taller to go with the flow of the roof line. Like the back of the Carrera GT, the 2 humps behind the sits but have them higher to flow with the roof!

But as it is it looks amazing!

Love the way the bodywork wraps round the wheels.

Nice work

Rich

You seem to be putting in three times more effort than me at the moment - looks great!

Is that a custom made screen? Car looks really menacing - i love the stance.

Looks stunning bud!

What's your day job??

Coming on nicely Andy

I can't help thinking that the air vents behind the doors are a little too straight and could do with moving the outer line back a little - a sort of slash cut?
Did you increase the angle of the screen, making it a little more upright?
As mentioned in a previous post, the body line behind the rollbar needs something - maybe raising to meet the roll bar and inserting a rear window?

Thanks for the feedback.

My intention for the bit above the engine is to have a side profile similar to the Porsche Gt (see my avatar). I have been resisting raising the panel to meet the top of the roll bar and adding a window as i think it takes away from the open air feel when the roof is off......

Your right I have raised the screen angle and the car looks better for it also adds to head room so its all good.
regarding the rear vent, I shaped it as it is to match the door and roll bar, although I would prefer a steeper curve. What I will try is to bring the lower part of it forward but I can't move the top back due to my rads and intercoolers.

Plenty still to do I think.

Gorgeous, stunning looks....

Lovely low stance and a show stopper... this is probably one of the best looking 'kit' cars I have ever seen!

I hope you get the engine cover nice as this will make/break the whole design.

Andy,

I'll pipe up here and let you know that for the most part I really, REALLY like the shapes you are working up. Nice. As commented above however , the rear does appear to drop away too much and would look better as you have determined with the GT humps, etc.

It looks like Andy added another page to his website.

Nice work Andy

Had not seen Andy's site till now, lots of great work going on there.

Andy - whats the wheelbase of that beast of yours?

Cheers

Fred W B

Thanks for all the possitivecomments and the advice on improvements.

More work done.... been having fun with carboard.

I have shown the first and latest iterations of the rear on my website and the latest has had some splashes of colour added in PSP.





The wheelbase is 2610mm and its 2000 wide.... I've actually managed to keep it quite short for its width at 4200.

Really, really like the prject Andy.

You got any more detail/websites about tuning that BMW v12?
I couldn't seem to find anything on your site.

I was thinking of using one in a dream future project of my own!

Cheers,
James

The cardboard looks great. Just brush on some resin and slap on some paint and you'll be done! LOL.

Resin on cardboard might work as a base for your plug work? Anyone ever tried that?

Not as daft as it sounds really - if you stretch some polyester material over the cardboard and then soak it in resin, it should make a very good basis for a plug.

A site I looked at for speaker enclosures uses that method. They stretch fleece material as used for jumpers and coats over the speaker and pin it into place then impregnate it with resin and hardener. When it's gone off cut a hole for the front of the speaker and finish it off with a smear of filler and paint. You can buy the fleece as blankets for not a lot.

I be liking that arse a lot

If it looks that good in cardboard how great will the finished article be

Cheers

Actually I intend to make it from thin MDF and then fibreglass the rear of it..... remove MDF and you have a fibreglass panel to work from.
This is how I have made a start for a few of the larger panels on the car as its easier to get nice smooth curves in MDF rather than with cardboard and thus less filler.

Been slowly working on the rear end..... I have a basic design that I am now mocking up with the actual lights.

Very nice.......

yes, that's looking great!

Superb. Vary sexy

Certainly floats my boat Andy

And here is the actual panels that I have made for the rear..... still some way to go but getting there.

I'm still torn about how to do the grill and exactly were to split the rear clip so that it can hinge... I'm thinking I may keep the rear end and spoiler in possition and have the rest hinge just in front of the spoiler at the vent.

It is worth remembering that the bodywork will be more rigid if kept as complete as possible. If you could hinge behind the numberplate area, keeping the diffuser part rigidly mounted, you could have the whole clip in one piece and lifted on gas struts. If split into two sections you will have more shut lines to worry about and rigidity will be compromised to a degree although there are obvious advantages to having the spoiler firmly mounted to the chassis.

Regarding the hinges themselves, have you thought about some heavyweight rose joints? I will be retrofitting these to my car when I get the chance. They will give a certain amount of in/out adjustment with a little design thought

Regarding body design, are you retaining the little 'spats' behind the rear wheels in the previous pic? I quite like the shape of them - practical too


[Edited on 28-11-06 by RazMan]

I know what you mean about the shut lines but at the moment I am thinking of splitting it there almost entirelly down to the rear spoiler mounting points.
I'm not yet convinced one way or the other, I prefer the look of the whole unit hinging like the Ultima but not sure its practical.

I am not sure what you mean by spats.

I think he means the bit that curves round to hide most of the rear face of the tyre. Oh, looking nice there!

Ok I think the splat behind the wheel must be refering to my attempt to show the rear panel curving to the wheel..... that is in the final design but there will not be anything else.

Here is me playing with the latest actual pic in PSP to see if I can come up with the final rear grill design..... but I am still not sure.

Looking nice. Questions: is the rear completely flat, or is there a curve to it? The interface to the side fender panels, will that be a sharp edge or radiused?

The rear has a curve in both planes and will be smoothed or radiused at the corners, I have kept the edges sharp so that I can get both sides the same easier.

Can you take any design cues from the Mosler, Alfa 8c or Elise Mk2. Granted, they have a flat top to the rear of the car but they are three very different cars with different approaches to a deep rear end (so to speak!)
