common guys we all know that Indpendent rear is better than a friggin beam no matter how you bend it twist it or what ever you wana do to it .I really cant imagine more than one post for this thread .If a beam setup was better than IRS then why would most every race car , sports car made have IRS vets since the 50's ,vipers,300zx,supra's,NSX,s13,s14,indy car,the list goes on and on
the whole point of the IRS is to keep contact with the road and the name says it all it allows each corner of the car to move indpendent of the outher to keep contact with the road . now if you just want to hit 3 wheel motion over speed bumps and **** yea go for the beam ,coilovers and some teathers to limit sys travel .But if you want to handel no contest go with IRS
