i just got wide front fenders on my gtr,

i need to run 30mm wide spacers to make my 17x9+21off wheels to fit the gap

my question is

what are the disadvantage of running such a huge spacers in the front ?

i'll be running one with a longer stud.

will the hub wear out? will i get slow steering responds ?

This moves the tyre contact patch outwards 30 mm, which means;

Tramlining, pretty bad I would say

Premature wheel bearing wear

Heavy steering

Hence steering linkage wear

And steering rack wear

Premature tyre wear

Increased loading on the radius rods due to the increased leverage

Leading to increase radius rod bush wear

Or if you have spherical bearings with adjustable radius rods, perhaps bearing failure

Premature wear of the upper inner and outer conrol arm bushes

Premature wear of the lower inner control arm bush

Premature wear of the lower outer ball joint

That's about it for a start.

:D cheers :yes:

PS; with the power output your engine is going to have, the tramlining will be extreme

how would these things not happen if the offset of the wheels were 0 and stuck out further? Or would then happen regardless in puttng a wider wheel with lower offset on the front

sydneykid, that's quite interesting what you said above. I was just wondering whether the same applies to using a different offset wheel too?

e.g. stock r32 gtr wheels are 16x8 +30. If I ran a 16x8 0 offset, that effectively brings the wheels out 3 cm right?

Will this have the same effect?

The car might tramline, but at least it won't look like a Tram with wheels hidden under the guards :)

As for the other questions, are you guys seriously asking if a wheel with a certain offset is different to

a wheel spacer combo with the same offset?

If one person is 6 foot in high heels and one is six feet with bare feet will they both hit their head on a 5'10 doorway?

It is the same thing. Adding wheel spacers effectively changes the wheel offset.

Legend has it that GT-R's don't really like having this sort of thing done to them...

Spacers aren't the answer, skinny front wheels hanging out side the rear track looks almost as bad.

A better answer is 10.5" wide wheels with 0 offset, making them 21 mm further out and 17 mm further in.

That will give a barely discernable increase in tramlining.

You will need to do a little inner guard tweaking, nothing major.

Obviously that's all round, so will need to match the rear guards with the front.

:O cheers :O

I got mine custom for $70 :nyaanyaa:

I think I got a catalogue at work that has them in there from some Victorian Company that makes them and other car accessories. and they are in there for about $130 for a pair ($65 each) Might have to check that price again though..

yeh the trusty SK tramline setup can be hard to drive..

i better not drift this wkend on my 18 by 9/10 neg 17s

suspension might explode on impact with tarmac

:D Cheers :P

*shrug* you can believe whatever you want mate, but personally, i'm with SK on this one... its sheer physics... and basic (i.e. year 9 level) physics at that.

    • The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow 
    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
