Hi, can anyone give me the correct tyre sizes for 19''s, there going on a 03 coupe and the new rims have arrived, front 19x8.5 [22 o/s]. rear 19x9.5 [30 o/s]. Ride hight is STD at the moment, will wait and see what it looks like first before I consider a drop, I will be wanting a moderate drop only, any idears on springs would be great! [Tein H/Techs or STD 350z springs] looking at about 15-20mm drop. In the US they talk about tyre sizes [for the above] either 245x35x19 or 245x40x19 front. and 275x35x19 or 255x40x19 also 265x35x19 rear. They say that these sizes are close to the correct rolling Dia, not shaw! Any idears guy's Thanks G.T. PS. Also any rec'os on tyre brands.

factory 19" optional rims have these tyre sizes I believe: Fr - 225/40R19, Rr - 245/40R19

Has the car been complied and registered (ie passed RWC and/or vicroads/RTA inspection) ?

If not yet best is to stick to that factory sizes above and make sure the compliance workshop have the 19" sizes on the tyre placard just to save you trouble.

if you're thinking to swap it, those tyre sizes above can fit onto the 8.5 & 9.5 wide rims but probably at the maximum limit. 225/40R19 is still good for front 8.5" rims as it's only 0.5" wider, but rear 245/40R19 might look a bit undersized as your new rims will be 1.5" wider at the back than std.

You can get either 235/35R19 or 245/35R19 for the front which is close to rolling diameter, and for the rear you'll need to get 265/35R19 or 275/35R19... but again if you wanna keep within the legal limit above the standard factory/dealer tyres, I'll suggest to take 235/35R19 & 265/35R19 as these are within 1" wider than the maximum tyre available/allowed on the vehicle. 245 front might work but I personally don't like the front to be too wide as it may make the steering a bit heavy on low speed and also the tramlining effect is increased on bumpy surface or in the rain.

PS: not much tyres available in those sizes, but I found probably Bridgestone RE050A is available in those sizes, also Yokohama V103 available as well in those sizes. Price is about $300-350 each...

      R32 Skyline Handbrake Question

      By GTSBoy · Posted

      That's f**ked up. I'd guess it's more likely that you have an entire S13 subframe in there. Does it still have HICAS mounting points? Seeing as it is quite possible that yours is the only such converted car in the world, you'll probably struggle to find someone who can tell you from direct experience. 'Twere I you, I'd be looking for 4 stud Skyline rear brakes and convert back. At a minimum. Preferably go find all the stuff you need to put it back to 5 stud (assuming you're happy to change wheels) and upgrade to some decent brakes. You don't even need much stock stuff. Don't need calipers or rotors, as you can go fully aftermarket. Just needs hubs and the other bits and bobs that are different to what you have now.

      R34 GTT idle problem

      By GTSBoy · Posted

      The engine has nothing to do with it. The physical space behind the headlight is the limiting factor. And the height. The height of the NS70 is the same as stock. So the clamp bar across the top goes on nice. The battery tray is big enough for it to sit on. The X is for extra capacity - it has even more lead in it than the non-X NS70. Heavy f**ker. But it's not a track car, so I will suffer a couple of extra kg. In the case of the R34, maybe the physical space there is not as deep (forward-backward, not up down). Hence why they say the 60 is the biggest. But I would never trust a catalogue to tell me what will fit. I have the car. I have the existing battery. I have the tape measure. I have the dimensions of all the available batteries. I find the biggest box that will go in. (With the right terminals in the right places, of course).

      R32 Skyline Handbrake Question

      By elinde · Posted

      Hello! I have been having a hard time finding the answer to this question… I have a R32 GTS-T Sedan than has been 4 lug swapped using S13 hubs, rotors, and brakes. The front has also been converted to S13 suspension.    When the swap was completed, the handbrake cables were never hooked up, as the S13 rear calipers are the “handbrake”, and not the typical drum on rotor that the R chassis are. Does anyone know handbrake cables that will work for this conversion? I’d like to not use a hydraulic handbrake and stick with the traditional cable style. My original thoughts were to go with S14 cables and try to make them work, since I’m pretty sure S13 cables will be too short.    Any help would be appreciated!

      I did some research, considering you have a neo engine, how is that battery compatible? I checked centuries website and super cheap and says it's not compatible. Only this full size one is. https://www.centurybatteries.com.au/products/ns60-mf

      No, lets be honest here. I went to Winton and did a track day, for all the mods and V8 power and craziness I posted up a time that a K24 stock motor Honda Accord can do on the same tyres (narrower, too) 250kw and learning how to drive the f**kin thing is the sweet spot.
