Staggered Wheel Diameters

Does anyone know whether running 18" wheels at the rear and 17" wheels at the front car work. Obviously i may need to tweak ride heights a little. But was thinking i might try to park 255 x 18s out back and keep the fronts to 235 x 17. Fir what i am trying to achieve it looks like hte overall gearing would be about right, i just dont want to run 18s all round for dollars and front guard clearance which may struggle if i try to get a 18 x 8.5 wheel up there

Manufacturers are doing it OEM these days, so there's nothing inherently wrong with it.

As long as your tyre circumference on the rear is correct, for the speedo, and the circumference ratio between front and rear is unchanged (for ABS and traction control, assuming you have them) then the electronics shouldn't know any different either.

There are valid arguments for puting the wider and lower profile tyres on the front, not the rear.

Wider - R32/33/34's have heavy front weight bias, in the case of 4wd over 60% on the front wheels. As a result they understeer, so why would you want to make that worse by using narrower tyres on the front?

Lower Profile - a lower profile tyre has less sidewall to absorb the torque hit, so a decent horsepower RWD should have a higher profile tyre on the rear, take a look at a top level Sports Sedan as an example of that logic. Lower profile is good for steering response, so they should be on the front.

Hence my argument would be to use the 18's on the front and the 17's on the rear. :dry:

Not that this has anything to do with performance, but optically on a vehicle the rear wheels always look smaller than the front, hence why a lot of cars run something like 18's on the front and 19's on the rear so the rear doesnt look smaller than the front. Especially on something like a skyline which has a big ass (compared to like a S15). Have a look next time you look at your car from a bit of a distance, the rear wheels look smaller then the front.

Hey Garry, the only reason I wanted to go the 18's on the rear is because RE55's only come in a 255 in a 17, and I'd like to run the 285's available in the 18's.

Do you think it would have an adverse affect on handling, considering I run 17's on my 180SX at the moment?

can i run 18s on the front and 17s on the back for occasional drift day and daily.

i was thinking of running 235/40/18 on the front and 235/45/17 on the rears?

i guess to fit the 235s on the 17 i would need the rims to be width 8-9?

A 180SX is not an R32/33/34, they don't have the weight of an RB. Unless you have done the RB conversion, in which case the rule applies (they understeer if you put smaller tyres on the front).

yup :down:

8 is fine.. and fits perfect

Many people in japan have 17s front, 18s rear. I dont see why not.

I had 16s front, 18s rear when i was at wakefield track day. Car handled fine

Just try it out and test the car for yourself.

If you have a RWD drive car..

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
