Cool Opel GT Group 4 Race Car

Hi

I would like to transform my Rally-Prepared GT 1900 into a Group 4 RaceCar! (In order with Apendix K for Historic Racing in Europe). Due to the fact that I do not have much time to go Rallying because of to much Circuit Racing.
I am searching for Information on Period Group 4 OPEL-GT's as the Steinmetz, Irmscher, Conrero, ...) as well as for the Specialpart, as:

- Schwedenkopf (Crossflow)
- Limited Slip Diferential
- Sport's or Racing-Gearbox

The aim is to beat up some Porsches 911 in the European Championchip!

Thanks for any Help!

The Conrero GT's were built to FIA 'Group 4' specs. So Rionart's GT (formerly Kyle's) is what it would look like. 'Group 4' later morphed into 'Group B' in the early 1980's, and we all know what became of that!

Here are the FIA homologation papers for the Opel GT.

The homologation is simply the allowances for a particular make/model of vehicle. So if the homologation for the Group 4 Opel GT calls for either a factory 1.9 head casting OR an aluminum crossflow 8-valve head casting, then that is all that is allowed. Showing up with a 16-valve head would be bad....

For the general jist of the rules, check out the FIA website.

These are the currently homologated vehicles in the FIA's database BTW. This means that unless the car is run in a historic class, once the homologation is over the car cannot compete at an international level.

HTH,
Bob

Will this never die!!
Andreu...DO NOT BUY FROM SHOWCARS. (Sorry I have to shout).
All they have for the Conrero are some pictures stolen from the internet.
As the current owner of the car in question, I have tried to put these clowns right, but I am wasting my breath.
Rgds, Rob.

Politicians and diapers have one thing in common. They should both be changed regularly and for the same reason.

Hi Rionart,
Thanks for you reply and advice, I found the picture of GT Conrero from showcars website. Even they have prices of all the spare parts of GT Conrero.
But I can see they are not serious company!!!!!
Maybe somebody knows the owner of this beautiful GT Conrero of the picture, and can tell me where buy this special Conrero fiber parts and the brand of the rims.
I have a competition of European and Spanish Historic Rally in November and I must to finish the GT a soon as possible (is the first Opel GT in competition in these championships)

Best regards
Andreu

LOL, Andreu, Rionart IS the current owner of this beauty. Here's a pic from the Carlisle show, with Rionart himself:
