Wheel/Offset calculator and simulator

So after getting a ton of headaches trying to calculate the spacer needed for the rims I'd like so a guy over on Hybrid Z linked me to this great site. So I had to share since it is a great help and definately alot easier check it out.

bump for greatness lol

What kind of rear axle setup are you planning to run?

Nissan 300zxTT rear diff (R230 think like 4.3 gearing) running to some inner Infinity Q45 shafts and a adapter made to mate with the stock wheel hubs.

Bumping my head against a wall trying to find the widest tire I can run on a 16x9 rim (yup found some two step rims i like better then the other ones lol) but dont know how wide I can go on a Z with the ZG Flares without going too overboard on camber to keep max contact for traction.

Correction 3.69 gearing i think ....

16" tires cost a good bit more than 17 or 15. That rear should be good for what you're doing. I was concerned about the stock one. Thought about a 4 link and a solid axle? That's how the KP61 comes.

Yeah some guys have been running solid or ford 9" but the R230 should give me the strength i need and decent gearing

Oh and finally decided on a Miro STP1 rim 16x9 on 255/50/zr16 tires on all corners.
