So i have Heard 18 x 9.5 Are the perfect fitment if you do not want to scrape or roll your guards. Then ive heard 18x 10 & 10.5 fit with proper offset and you dont need to roll your guards can someone tell me once and for all what is the absolute limit without scraping and rolling guards?

It depends on ride height, I fitted 18x10+18 on mine lowered slightly without rolling any guards, then when I lowered it more with coil-overs it required one of the rear guards to be rolled. Guards sit about 1 mm above tire though

End of the day you will be able to run a 10 or a 10.5 without rolling but not with a very low ride height

I have 18x9.5 with an offset of +12 and had to lip the guards a little, plus I get some rubbing on the inner guard when turning. Also running 265/35 tyres, lees wide tyres would reduce the need to lip guards, as would offset of +15.

Here's some pics with some suspension bump applied, (and semis in 265/35)

I dont know how low my car exactly but its lower then factory... The front Oem lip sits about 10 cm from the ground, So no sure how low that is compare to factory but i want 18's do you think with that ride height i can fit 10inches?

R32 GTR, 19x10 +20, when lowered needed the guards rolled/cut a little due to running 275 tyres, a narrower tyre would have been fine.

    • Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate 
    • He means "as opposed to mechanical cable drive". Older cars (R32 for ex.) had cable drive. Later cars with essentially the same gearbox, ie R34 GT (NA RB25) used essentially the same box as the R32 GTSt, but instead of a cable drive, had an electronic speed sender plugged into the same hole in the box, running from the same little gear that would have run the cable. Some of the shittier later cars use a speed sender on the nose of the diff, or the ABS sensors.
    • Lower than engine, or lower than it should at the hubs? Either way, that is a nice power figure and I'm not surprised you say it rips now. What stopped you from turning it up any more? Injectors? Or did it just stop responding to boost?
    • Got my 34 gtt tuned last week. Car made 362 wheel horsepower at 19 psi. Turbo was the ATR43SS. Only other upgrades were haltech 2000 series. 650cc injectors, walbro 250, fmic. Pro hub dyno reads 6% lower than actual figure according to my tuner. Car is a real ripper now.  IMG_7261.mov
    • Hi everyone, I'm wondering if anyone in Melbourne (preferably West) has a non-S2 R34 front bar. If it's already off the car, even better!  Nothing too weird, I just need to get a cut-out of the hole that the front indicators clip into 🤣 (image attached for reference)   I've got a front bar from JSAI Aero, but those holes need to be cut myself, and I want to get it right so the indicators will clip securely. And my OEM bumper is a S2, so I have no reference. So looking for a member who might be able to spare me a few minutes to make a cardboard cut-out using your front bar.
