I'm not sure if a VZ cradle will fit, apparently they have different shocker mounts and the tailshafts are different. but idk i thought it was anywhere from vx2 untill vy2. But you may have to see how you go.
Okay so when i did my cradle and put in super lows it was fine and drove it around for a night, because it hadnt been aligned the camber was tucking the rim under the guards so no bad rubbing. The next morning i got a wheel alignment and it fixed my toe completly and camber quite a bit, but this presented the problem of only having 5mm of clearance from my 245/35/19's
so i went back to fe2
this may be because of the gas tank but you may clear easy.
Anyways me and my mechanic mate did it in 2 days because we rounded a tailshaft bold and had to get a new one the next day. if you want i write up a little how to, dont have many pictures but can get some? If your know what your doing and dont mess up it's an all day easy job
