Building a Gr4 replica

Peter, that's a great color. Enginebay looks great too. Is that color similar to the original?

I think that is the Ford "Poppy Red"? It looks really nice.

The Detomaso Pantera Red is somewhat orangey also.

It really jumps at you in the bright daylight and I like it a lot more than the Ferrari red.

Looks great. Nice job.

My car is 2003 Lamborghini red . If the sun hit it just right it can look orange too.

I guess it's time for an update on the progress on my gr4 car which, well, is close to none. The car still sits in the paintshop and not much has happened. Hopefully things will get going this month - atleast that's what he has promised.

Meanwhile a few parts have turned up. It took AP RACING 6 month to finish the rear calipers for the car. Again, these have to be homologated for them to be used in historic events here in europe.

I had the choice between the Girling 16/4s made by Bg Development and the AP Lockheeds of AP RACING historic range. I went with the APs (remember, I have AP 8-piston calipers for the fronts), as they are lighter than the Girlings and have a greater brake pad area. They are availible with different piston sizes, including the 41.3 mm homologated for the Gr4 Pantera. Also, a feature I liked was that they have blank lug mounts, meaning I can drill them to match the bolt pattern on the rear uprights and thus avoid using adapters.

Here's a Picture:

Another

The rotors are 304x28 mm, also from AP, Again size is dictated by what is allowed by the FIA

Another neat piece is this dual master pedal assemply kit that Scott (SACC restorations) put together for me. Pretty much his standard set-up, but with Girling masters instead of the Wilwoods. The kit includes a proportioning valve and a remote adjustable balance bar.

Very nice components. I just reviewed your entire build post. Terrific work all the way through!

Allthough progress is INCREDIBLE slow, there IS Progress at the paintshop. They finished prepping the body, and expect to start painting the car Next week!!

I'm pretty obsessed with getting the red color for this car right, i.e., getting it as close to the original red as possible.

So i did one further check of the color we came up with. The red was mixed from a scan from the original red on an early '71 headlight bucket BUT, is the early '71 red, the same as the red used on the later '72 euro GTS and Gr4??

So I send the paintsample to Chris Beck in Switzerland to compare it to his original GTS red.

I think it's pretty convincing, they compare really well. Good thing is, that the color is a modern paint from a Renault that can be mixed at any time.

Seems to me that the colour matches perfect

Hello Kristian
Did you build some hats for those rotors ?
I've got the same for my gr4 project, still not have the hats ...
Thanks
Philippe

Philippe,


I do have some set of hats, but I'm not sure they will be right. I'll be experimenting with rotor offset when I get the car back.

The hats for the AP rotors will likely need to be custom made. AP doesn't offer universal hats.

Wilwood offers a few hats with the AP 12X7 rotor circle and ford 5X4.5 bolt circle that may work.

Hello Push,

on your original post a long time ago now you mentioned the history of your car, sold by Claud etc etc.

I also own a 72 Euro GTS number 3840 and am interested in where you found out about the history of your car.
Santiago Detomaso I cannot contact for some reason

regards Peter

that was my idea

I always loved the rear view of a wide body car

Here's a $100 project for those wanting to shed some weight of their Pantera.

Building an aluminum skinned front lid.

This is of course for my Gr4 build, but it would be pretty cool on a street Pantera too.

I had an old accident bend front lid lying around that I wanted to experiment with. So I separated the outer skin from the inner structure.

While I had the inner structure media blasted I started working on the outer skin. Bought a 1 mm aluminum sheet. Using an intact lid as a template I cut the sheet into shape

Then, again using the intact lid as a form, I carefully bend the sheet around the lid and slowly shaped the edges with a hammer, while keeping track of measurements.

A couple of hours and the skin was almost finshed
