Hi Mikko,
thanks for the pics and the advice

You seem to be a "hardcore" guy

) I am not aiming to race with the car. I want to make it street eligable. So such dramatic actions will not be in. Over and above i want to keep the car as opelish as possible. So i will be using original oel parts as far as I can. I want the IRS for its squat properties I like it when a ca squats everytime you apply the power
Why I am aiming at the V6 Opel engine/ Tansmission? because you get parts for those around each corner here. Even my dealer has promsed to service the car and fix it as normal. I do drive though an Insignia OPC with 325 bhp so I have my fair share of power and do race with the car on the Nürburgring
I will keep you posted about the developments. Merry Christmas and happy new Year for th tim being.
Cheers
Walid
