Now oddly, the top photo looks much more like a Z3 than the others have done, IMHO!

well the doors and windscreen are still Z3... so i guess there is plenty of original DNA there.

I know - I just meant that that photo seemed to emphasise it more than the others you've done.

Didn't read the whole thread but has anyone asked how access to the engine bay is achieved? Does that whole front clam section hinge forward or are my eyes getting so bad that I cannot see a bonnet split line?

the whole front section lifts up on uprated gas rams... see the link above :-)

I wish you'd get some decent pictures taken! Every snap is a reflection of your business. MPV, garage doors and a wheely bin in shot really detract from your cars!
i take your point crack fox. I only posted that pic as people asked about the bonnet. im pretty happy with the recent photos that were taken for the three big kit car magazines that used their photographers.
They are on my web page and some are on this forum thread. These are my favourites:

these two are from the feature article in Total Kit Car magazine....

How did you go about the whole design and tooling process? Did you 3D scan the original panels, design the new parts around that geometry in a CAD package and then give the data to a supplier to kick off tooling?

Just had a great weekend at the Donington Kit Car show!
Complete Kit Car magazine purchased a Bertini Kit and built it during the two days of the show.
I have a few photos of the build at the show on the Bertini GT25 facebook site. But I thought I would share a link of a video I took of
the guys at Complete Kit Car Magazine celebrating finishing the kit on Sunday afternoon.
They managed to strip their Z3 2.8 and fit the kit + electrics, ready to paint over the two day show (just 12 working hours). The two builders had kit car construction experience. But had never stripped a Z3 or built a Bertini prior to the show!

Thank you Crack Fox!
It was a great show for me. lots of interest and I lost my voice on the second day.
I think i will be at the Kop Hill Climb next at the end on september. That might be worth a visit.

I know it'll more than likely get me shot, but I think the stance is wrong. I think the front end needs to come down a little to offset the the bonnets visual lift when viewed from the side.

Appreciate that in the flesh these cars are probably a lot lower than they appear in the pics.

Still great work. I prefer the front to the rear though.

The whole car is getting 30mm lowering all round. plus it had been on axle stands all day which would have pumped up the suspension a bit. They would have fitted the springs at the show, but they forgot their spring compressors.

I was a bit nervous before the build as it was a pretty public display, about 5000-6000 people over the two days saw it. But it went really well.

Had a great day at brands hatch with the Bertini GT25. It performed really well keeping up with most of the more track focused westfields etc. Very very wet and loads of tail happy fun!

Always nice to see an update to this thread, have any customer kits have left the 'shelves' so far?

Yep I have sold a few. Could always do with more. But the editor of the complete kit car magazine has purchased and built a kit. So that put a big smile on my face. Especially as he is doing a 5 month build feature on the car. I'm hoping things will take off at the stoneleigh kit car show next year. It a huge event and a great day out.

The Bertini bonnet even with the lamps fitted is much lighter than the BMW bonnet, bumper and crash bar that came off so that will also contribute to the high ride height. Ash has since cut down the outer edges of the crash structure and refitted it.

I was quite impressed by the design of the bonnet, it has an internal bonded section moulded from the BMW one so that it it pretty rigid for a grp item. It also seals onto the original rubbers so that the cabin air inlet remains isolated from the engine bay etc. It took about 10 minutes to fit once the original parts were removed, fitting the lamps took a lot longer, however it is possible to run the wiring behind the inner skin so you can make a pretty tidy job.

Fitting the kit was really very straight forward, we didn't even read the guide until we started, given that you would still need to sort out a silencer you could have a drive-able car pretty quickly. The real work is in the finishing, getting the panel gaps spot on, prepping for paint and re-trimming the interior, if that is what you want, will be where the time is really spent.
