Hey guys, new to the forums here, just after some help in regards to a Corona. I've owned and moded a few AE71's and KE70's in the past and loved them. Haven't touched cars in a few years but keen to get back into something fun again. Really like the RT142 shape but need some help. Just want to know the easiest path to put coilovers & a locker in them & any other useful suspension mods (RCA's, Panhard, fresh bushings blah blah blah). I've had a look through a few members rides and some people are using RA60 gear and some using S13 gear so I'm a bit confused as to the best/easiest bolt in stuff to use? Any help and advice would be sick, cheers.
