i was loking at a fiero at the junk yard yesterday and and was looking at the front end to steall the front disc and calipers or=ff it and was thinking why not just swap the whole cross member under and opel it has a fron mount rack and it uses coil springs in the front i will have to do some measurements but it looks like to will fit alright
i was really writing this to be curious if anyone has done this or has tried
also i was looking at an impulse rearend and i notice the torque tube on it was aluminum and two piece aswell as the pumpkin which i thought was odd because i thought it was steel like the the gt

Bob Dennard of TGSI Racing, alhtough he has not been around this site in some time, is an Opelholic, and according to his website, was looking into campaigning a Fiero for racing a few years ago. The SCCA nixed the ability to alter the programming in the Fiero's engine controller, so he nixed the project, but I am willing to bet that he still has a Fiero or two, and several GT's and could probably make a fair assesment as to viability of this mod.

The cars are closer related than you might think. 1984-1987 Fieros used a Chevy Chevette front suspension, mildly redesigned. The Chevette chassis is basically a Kadett C chassis, same as 1974-1978 Kadetts. So the front suspensions are quite similar.

Of the three Impulse rear ends that I have pulled they all had a steel torque tube. As for swapping out the Fiero front end I am not sure if they fit I have not checked them out. However I do know that the Isuzu Buick/Opel (Kadett C) front suspension will work on the GT Uwe in Germany has one installed on his GT, he said it handled and drove like a go-cart. The Impulse front suspension will also work under a GT, how it handles I can not say right now, it is still being worked on along with rebuilding my engine and rebuilding a five speed. I can say this, for front suspension conversions be it Kadett C or Impulse it is a lot of work and not for the average Joe to do.

HTH = Happy to help.

The fiero front springs may not be heavy enough since the engine weight is in the rear. You may want to check into the spring rates and possibly get some that are stiffer if you pursue the project.

Very true Dan, I once got a set of 'performance' Fiero front springs to rate and they were only 200 lbs/in.
