Haha yehhhhhh, I've got 235's on the front of mine which sit almost flush. Lowered the car a bit too much for a car show and they did an excellent job of rolling my guards :P

What kinda wheels u have on ur gtt.. offsets? Currently still shopping but not sure what will look good..

any pics of urs?

18x10 +20 will fit the rears, but its best if you get smaller tyres, something like what shinobi_s14 posted (235/40)

I'm running 18x10+22 with 245/40's and I had to get the guards rolled, to make them fit

As for the fronts, 18x10+20 gonna cause you a whole heap of trouble lol

edit: Here's an idea how they'll fit

I've got Wolf S36's. 18x8.5 (235 tyres) on the front, 18x9.5 (245 tyres) on the back. I forget the offsets though, Lachlan would probably be able to tell you; eh Hank? thumbsup.gif

I don't have any good pictures of current fitment, this is the best one I have:

Wow it was truck spec back then... I have since lowered it right down so the guard is almost tucking rim. At the moment the tyre sits about 2mm inside the guards with the lip rolled. And that's with the camber I'm running without adjustable arms. When I get adjustable arms, they will sit very flush. Plan is to get 235 tyres stretched on the back so I can fit them thumbsup.gif

Rule of thumb that helps me with nissan: the higher the offest the more tuck/further in the wheel will sit; the lower the offset the more dish/closer to the guard. That's why GTR's wide body cars need lower offsets to fill the guards

do a search mate, plenty of helpful diagrams and explanations around.

Whys everyone advising against 265 on the rear? I'm running 265/35/18 on. 10" +25 with rolled guards, no issues at all. If you like the stretched look then go smaller and be cool. If you want to utilize the benefits of wider tyre and get more traction then go wider.

Who advised against 265's on the rear? On the rear they will be fine depending on how low you want to go etc. It's the front where they have no chance.

Thanks for the feedback guys :) prob not Gona get them now..

Can someone please explain (in plan English) how to actually determine ur offsets and tyre sizes tho because you guys seems all have different :s

Offset is the measurement used to determine the position of the hub-mounting in relation to the outside of the wheel. So an offset of 0 will mean that the hub-mounting surface is in the centreline of the wheel, a negative offset means the hub mounting surface will be located more towards the inside of the wheel, and a positive offset means it will be located more towards the outside of the wheel. The +xx measurement you see is usually in mm's, so a +35 offset will be 35mm away from the wheel centreline towards the outside of the wheel.

Obviously this measurement means different things on a different sized wheel. So a 8" wheel with a +20 offset will not be the same as a 10" wheel with a +20 offset, as the measurement is taken from the centreline.

Um read the posts above they're saying to go for smaller tyre for stretch. I'd go 265 minimum on "10, stretch is cool and all but I'd rather better traction over coolness.

Yes, sorry, I missed a couple of posts there.

I would go 245's or 265's on a 10". You really won't notice the difference in traction between 245's or 265's unless you have quite a lot of power. I'd say it's better to spend the money you save on getting the smaller tyres on a better quality compound tyre. 245 semi-slicks will out-perform 265 street tyres any day...

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
