Ok i just went today to get my new 17inch 255/45 tyres fitted to my r34gtt rims, on my r33 gtst. i originally had 235/45 17 inch but decided to go bigger for more traction... The guy at the tyre place said that these are 2 big for the guards and i need to get them rolled... he says that the 255's will give me less traction than the 235's cause they will dement and go out of shape when on the roll? What should i do, are the 255's really to big for my r33 or should i go and get 255/40 profile to narrow them down a little?

Sounds like you need to find a new tyre shop. If you have high enough tyre pressures a 255 will always have more grip than a 235 of the same tyre.

With the correct offset in the wheels, people have fitted up to 275s. I had 265s on mine but did need to get the guards rolled. Also, its unlikely he can tell for sure that the tyres are too big unless he has actually fit them.

I can't really go any wider that 235 on the front, but it probably wouldn't be an issue if my car wasn't so low. I ran 255's on the rear wthout any trouble at all and will soon be going to a 275, which will probably require a bit of guard rolling. You really shouldn't try to go to a 255 on the GT-T rims though as they are not wide enough as blade stated.

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
