best offset for R34GTT?

[n15m0]

hi guys,

Looking at purchasing some 18s for the R34GTT the offsets are:

F: 18x8 offset +22

R: 18x9 offset +40

I'm not really across how the offset figures work but would this be a suitable or respectable offset for an R34GTT?

Thanks all for any responses in advance.

Cheers

Jon

the optimum 18inch wheels and tyres combination for a GTT is

Front: 18x 8.5 (35 offset) 235/40R18

Rear: 18x 9.5 (38) 255/35R18

thanks for tht jake! awesome site!

this is the result I got...which I presume is fine

Your new wheel will have the following chracteristics:

The clearance from stut housing to the inside of the wheel will be 13mm MORE

The outside edge of the wheel will EXTEND an extra 13mm

I found that with 235 fronts I need to fit 265 rears as my 255's caused a TCS error explained below

235 = 79.8 inch rolling radius

255 = 78.6 inch rolling radius

The TCS can see this difference and , on my car, activated the TCS above 140kph (the rears were doing 2mph more than the rears at that speed and the TCS saw this as wheel-spin)

Fitting 265 tyres cured this as there is only 1/3rd of an inch difference so no wheelspin sensed (unless you really are wheelspinning!)

The Offsets are also good for 8" wide fronts and 9" rears (as on mine)
