Legal size for what?? As long as most of the tyre is cover by an arch of some sort then it can be as wide as you like!

not in NSW without and engineers report.

legally ypu can go 1 inch wider and 1 taller then the largest option in the placard.

so, non vspec, will be 17x9

vspec should be 18x10 (I think, cant recall width of bbs)

still has to be within guards, not foul aywhere on body or chassis, and not increase track by more then 1inch.

Are you planning on running staggered sizes? Because you'll have a bad time.

I run 18x10 +20 with 265/35/18. Guards have to be lipped and run some negative camber.

Would 18x10 +25 or +30 make things a little easier?

Not sure, I haven't measured the gap between wheel and struts. But it looks like there isn't much room left. +25 *might* hit the struts depending on what you're running.

Perhaps run a 9.5 +22? You can still slap 265/35/18 on them and it'll fit. Note that tyre design plays a part in fitment as well. The old Potenza tyres that came with the wheels had a more stretched design compared to the Falken FK452 on there at the moment. The Bridgestones fitted without rolling the guards, but the Falkens rubbed (bought a guard roller + heat gun and rolled the guards).

vspec should be 18x10 (I think, cant recall width of bbs)

I'm pretty sure R32 V-Spec BBS are 17x8 +30

I ended up getting 10.5 +25, trial fit of the wheels without tyres was fine. I now have 265/35s fitted but haven't had time to try them yet. I'm concerned about how the curve of the front upright comes in (toward where the tyre will be) where it mounts onto the upper arm. Might get tight there. I have already rolled my rear guards - i needed that for 255s on +20s on tyres with a generous treadwidth (IIRC the Falken RT-615 scrubbed but whatever was on there before didnt).

Well with my 19x9.5+25 i have sfa between the front upper arm and tyre. Im running stretched 245s pirelli p zeros.

Adam, your wheels have 13mm less clearance than my above setup but running 18s should help with smaller rolling diameter...hmmm

I've trial fitted a front +25 wheel with a 265 and there's ~9mm clearance to the curved upright. so that looks fine. I haven't tried a rear or driven it yet - need to fix an oil leak first...

My thinking was that since 255s on a +30 rim worked, 265s on a +25 would have the same clearance to the upright. Of course i then found that the Dunlop 265s were about 20mm wider at the tread than the Toyo 255s...

      Genuine nismo N1 rear pods - anyone got any?

      By Sleepergm · Posted

      I’m sure this has been discussed many times. But anyone have any or know someone that is selling genuine N1 rear pods? I’m still shocked no one replicates these yet. Looking to buy some. Added a photo of the part. 👍🏻

      Alcon TA6 Calipers on R33 GTST - Flexing

      By Nismo32 · Posted

      Hello, The dog bone wont have much to do with this - the calliper applies a load about the disc - the outside of the calliper is more flexible than the inside by virtue of it not haveing the big torqued down bolts, additional metal structure on the caliper itself, and mostly not being cantilevered. So the outside of the calliper is pushing away as its more bendy and brining the inside with it as an equal pressure on both sides of the caliper looks to cause more flex on the outside - which makes sense. I have done this same thing with the calliper unbolted from the dog bone - same thing happens. Although id have to watch more carefully to see how much more the outside moves than the inside in this case. Im guessing there is a point in the pedals travel where the pressure is not actually increasing in the system - its just volumne displacemnt - and because the outside of the calliper is more flexy, it receives that volume. Have gone back to Alcon again - but beyond a resolution there I would stay clear of this calliper and possibly any of the lighweight type of callipers - especially if you have the smaller 15/16" master cylinder. Cheers.

      Yes, you can very clearly see from more than one angle that it is the whole caliper moving left-right, not deformation of the caliper. The top moves, the bottom moves. Equally. It should be possible to see where the movement is occurring. Just need to look more closely.

      Water pump replacement - Sydney region

      By billyons · Posted

      Hi Folks, my 2009 Skyline 370GT “Crossover” wagon is losing water and has been diagnosed as needing a water pump replacement (it’s an internal timing-chain driven unit, not the usual electric type that seems to be used across many manufacturers). Am looking for any repairer recommendations in the Sydney /Wollongong region who can be trusted and are experienced in this sort of work on the VQ 36 engine. Many thanks….Bill

      While all of the above makes sense, we're not talking about some Ling Long calipers of AliExpress; Alcon would have to be one of the top 5 caliper suppliers in the world and these are not their budget units. If there were manufacturing defects in the caliper causing this issue I'd be very disappointed. Having re-watched the video a few times I think it's dog bone/mount related. The caliper moves independently to the rest of the suspension and brake assembly which suggests to me that it's not mounted rigidly. I know this sounds stupid, but have you got enough thread on the retaining bolts or are they a poofteenth too long and it's not super tight? For axial movement to be occurring without deforming the caliper that can be the only answer.
