how much does rim size affect the cars performance? handling etc.

i have an r32 gtr and ive been looking at rims over the weekend and discovered a lack of options but other then that i just want to know all the good and bad to go with getting new rims for a gtr, because theres the talk of spacers, offset, diameter, etc.. i was originally just looking to go with 18s but i found the ones i want, and they are a 19inch x 9.5 comes with 275x30.. would look perfect but hesitant on the above?

Well my ten cents worth.

1: 19" rims are a waste of time on an R32 GT-R.

2: The heavier the rim the worse the ride/handling/grip/tyre wear of your car will be.

3: The larger the rim the heavier it will be.

4: The larger the rim the more expensive it will be - same goes for tyres. Unless you buy cheap rubbish in which case you will be punished with a heavy rim.

5: The right offset for an R32 rim is +22.

6: The right rim width is 9 inches or maybe 9.5 if you want to push it.

7. Tyre size should be 245 or 265 in 18's. Any larger than that & you get clearance issues at the rear. You may get them anyway if you lower the thing to any degree.

8: There are plenty of options if you are prepared to either wait (Ex Japan) or find something second hand.

9: GT-R's are too nice a car to put bad rims on.

My recommendation?

18*9 rim in a +22 offset with either 245/40/18 tyre or a 265/35/18 tyre.

    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
    • I thought the same to start with. But then I thought it was one of those LCAs where the end of the ARB goes through a bushing in the LCA itself, instead of having an end link.
