well if you have 19s on a 33 it can be defectable as 18s are the biggest you can go. im pretty sure different size rolling diameter is illegal too. whatever state you in, check the on the state roads website for the rules and regs.

my moneys on defect. but hey... every mods pretty much a defect nowadays. :)

There shouldn't be a big difference in rolling diameter if you're using the correct tyres.

I'd say that they're illegal. I remember someone saying something about if you've got 225mm tyres all round, you can't go larger in the rear and not the fronts. They must stay the same width (all four 235, 205, etc), but if they came with 255's in the rear and 235's in the front, then you can go what ever you like in the rear and front (doesn't matter if they're not the same). I would say that it's the same for rim diameter. If your car came with 16's in the rear and 15's in the front then it would be legal. I'm not saying that this is the law, it could be complete bullshit (I think it is), just thinking out loud.

you'd be dumb to put it on an AWD

there was a topic bout a ferrari with 20" front and 22" back a while ago

unless you got adjustable suspension your car'll look like it just got anal probed

he has a gts-t...

if he got the right tyre profiles should sit evenly i think.

not sure if it helps, but a chrysler crossfire has bigger rear wheels from factory,

I think 18" front and 19" rear

I think the rule in NSW is that you can't go 1" bigger than factory and something to do with the width of the rim

Why not just go 18's all round? or 19's all round. Would probably be cheaper aswell.

Most ppl only do the 'smaller at the back, bigger at the front' So they can lower the car heaps and still be able to turn the front wheels yet fill out the guards.

But ive yet to see anyone do it with 18's as its too small to fill out the guards to the extent of rubbing.

i was just pondering the idea, i saw a few pics of a s15 with 18's on the front and 19's on the back and it looked really good. also theres some mags i like, except the 18" one only come in 8" width, but the 19"'s come in 8" and 9.5". so i was thinking maybe 18" by 8" on the front and 19" by 9.5" on the rear. just checking out all my options before i buy :D

Most people get smaller wheels out back because of cheaper tyre costs and larger wheels at front to clear their massive brakes. Usually see 17's out back and 18's up front.

If you get the right profile tyres, nothing/not much should happen to the speedo. Having 19's at the back and 18's up the front is no different to having 19's all round or 18's all round if you've got the right profile tyres.

It will depend what state you are in. Check with the transport department & get it in writing if you can, so you can proove your innocence when you get pulled up.

thats my advice.

There was an MR2 with 19's on the rear and 18's on the front. I think it was in one of the Video Option dvd's... Looked pretty good.

I doubt it's a legal requirement to have all wheels the same including the spare. Think of all the cars with space savers.... including Skylines...

In saying that. check first.

I reckon you could easily get away with it, as only 1 inch difference would be hard to spot by the authorities. My R33 has been running around on 19x10's and 20's for around 2 years, and yet to have a problem with the coppers..but i guess as with most things these days its the risk you take..

If you want to go 19's in the rear and 18's up front, just do it. Chances are you'll probably get dicked for having tyres that are too wide or you increased your track by more than the legal limit anyway.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      After market rear camber arm adjustment

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
