25mm rim offset for R34 GTT?

Hey guys :)

I don't know much about rims. I'm looking to get new ones for my R34 GTT (coupe).

The wheels I want to get are Rota Grid 19x8.5 +25. http://www.rotawheels.com.au/wheels/rota-grid#!prettyPhoto

What's the maximum offset I can go? I have coil overs and stock guards, fenders. I currently have Lenso 19"x8.0 on all 4 wheels and I think the offset is around-about +42mm.

All my tyres are 245/35/R19.

I know there's a forum on people posting their wheel dimensions but I can't seem to find anyone with this setup on a R34 GTT.

Can anyone check if this will fit. I don't wanna spend heaps of money then find out it scrapes on something when turning...

You know you can work this out for yourself, yeah?  Work out the offset difference, so you know how much further out everything will poke, then take a look at the car and see if that much extra poke will make stuff hit other stuff.

This tool https://www.1010tires.com/Tools/Wheel-Offset-Calculator#

will tell you that you will move the outer edge of the wheel/tyre out by 23mm.  If you have close to an inch of free space, then you are gold.  if you do not, then you need to reconsider, or plan to bash guards, etc.

I run 18x9.5 +20 with 235/40/18 tires and they scrub the guards when driving over bumps; a guard roll (at a minimum) is highly recommended.
