ALL,

So I just got my newish 1997, R33, RB26DETT fresh off the boat from Japan.

It has a drifter setup, 265-35r18 stretched out on 18x10.5" wheels Advan T-5.

I am looking to shoe it with 275-35r18, on 18x9.5 or 10" all around. I am looking for backspacing advice

I need to get rid of the 12kg springs placed on the NISMO cartridges it is 90mm off the ground and illegal here in NT, Australia, but made it by on compliance ??

I am going to roll the fenders in the rear if needed, but I need to know a rough idea for backspacing front and rear so I can begin choosing wheels.

Any tips would be greatly appreciated.

The car will have occasional track days, but primarily driven in a spirited manner to and from work, and all around the rest of the time.
