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...

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
