That's my point, while it my not be a "IRS", it would solve the reliability issues assiocated with BIG HP Z's and the "Datsun IRS". This NASCAR type suspension, also refered to as a "truck arm" or "3-bar suspension" offers a reasonable solution dollar wise. Not to mention, bigger gear selection, wheel lug patterns, brakes, and the ability to run BIG/WIDE meats on the rear, without having to flair the fenders! Making huge amounts of power is useless if you can put it to the ground!
This is good folks, keep it coming!!!
