Hey guys!

I have an R32 GTS4 - Yes.. I know.. strange choice for drifter.. dont worry.. ATTESSA is going to be stripped out soon.

Now, I need more lock on the thing! I find myself hitting full lock very often and not getting that sideways.

I have a couple of questions,

1) Is the GTS4 and GTST steering rack different? I find that my GTS4 has the turning circle of a truck. Would it be worth tracking down a GTST steering rack?

2) What steering racks have poeple swapped with the R32 rack for more lock?

3) What products (steering rack spacers, tie rod ends, lower control arms etc.) have people used to gain more lock? Any feedback? Whats good? Whats crap? Prices? Where can I find them from?

Any other feedback on what people have done for more lock would be greatly appreciated!

Thanks guys! :)

it's nothing to do with rack. it's to do with the fact that your car is 4wd and as such has front driveshafts. imagine the driveshaft angles!! that is why you cannot get much steering lock on any awd car, front driveshafts.

the only way out is remove the drive shafts, weld up sump etc. but it's a shitload of hassle. would be far easier to just start with a 2wd car. plus with your current car you still ahve extra weight of transfer case and any other awd associated bits.

Thats all well and good.

ATTESSA will be stripped soon enough.. rip out the front diff and use a RWD sump.

But once thats happened.. what can i do for more lock?

well first it's good to know exactly what's restricting lock. the steering rack only moves so far, the knuckles have a stopper which corresponds with a little tab on the LCA which stops lock, the tyres can foul against the chassis rails, and the knuckles start binding past a certain amount of steering angle.

so first things first, u can put some steering rack spacers which allow the rack to move further. from here the knuckles will start to stop on the LCA's, so u will need to modify either the tab on the LCA, or the stopper on the knuckles. around the same time u will have issues with tyres fouling on the chassis rails depending on what tyres/wheels ur running. if the tyre is big enough and offset is high enough u will have issues. for example i scrub with 5mm rack spacers, 17x9 +24's with 235/45's. few things u can do to stop this, either go lower profile, thinner tyre, or lower offset. u can also go longer LCA's like R33 ones which push the wheel out a bit further.

from there u will start experiencing binding issues on the standard knuckles, so then the next step is new knuckles or cut and shut ones. this can change things like ackerman angle, length of the knuckle, shape etc etc, which not only provides more lock, it reduces binding and changes the feel in the steering, as well as the turn ratio.

Interesting that you scrub with that offset stewy?

I have installed the 5mm rack spacers in my 32 gtst and the increased lock is quite massive.

I am running R33 GTR wheels 17x9 +30 with 235/45/17 tyres and it doesnt scrub on the rails. I definitely couldn't get more lock as the wheels nearly hit the castor arms at the front. I have noticed that the tabs on the LCA are now doing their job and stopping it there. That's a good thing!

My only problem now is that my solid brake lines on the caliper are now pushed onto the rim at full lock. Not a good thing! I'm investigating braided lines now.

yeh, i should note however i had extra lock due to the tabs on my LCA's being dented in a good 4mm from hitting the lock stops drifting over time. i keep forgetting about that haha. when i put R33 LCA's in with undented tabs, they gave me a few cm of clearance from the rails. but they did pull the wheel out a bit due to being longer.

and it was very minor scrubbing, in fact i didnt even notice it drifting on full lock, it was only when doing a u-turn or something at full lock on uneven ground (up a curb or something) it was just touching the rails.

This is a stupid question..

But what are steering rack spacers?

What do they look like?

How do they work?

Are they similr to some sort of shim?

How do you install them?

I have wondered about installing steering rack spacers on my car. The thing that I am not sure about is that if these spacers allow your wheels to travel further, wouldnt you run into problems with the wheels rubbing on the front sway bar and castor rods? My wheels are already rubbing the sway bar and castor rods at full lock. I have 17" wheels with 235's, car has been lowered slightly.

Thanks for that Nisskid. I understand how spacers allow the wheels to travel further, but am I still right to be concerned about extra rubbing as a result? See my attached picture (I apologise in advance for how crap it is).

With the further travel of the wheel, wont it now rub on the castor rod + front sway bar (the pink bits on my pic)? As my wheels already do this when at lock I am wondering if spacers will even do anything for me. IE: having extra travel isnt go to do anything if the wheel is already stopped by other suspension bits.

Sorry for stealing thread a little but hopefully we can all benefit from this :D

My R32gtst has s14 rack (more lock) and spacers (more lock again) and does not rub on anything. 6.5 caster, 3 deg toe out, 2inch lower than standard ride height. I run standard wheels with 205/50 tyres. hope it helps a bit. :)

I noticed the GTR racks a re totally different to GTST. it was as if one side had a different knuckle geometry to the other. one tie rod was longer than the other..also you can buy AM tie rods with integrated spacer and comes with thinner spacers (washers) to give you max lock.

So as a temp measure for someone with 33GTR wheels and tie rod spacers whos wheels are hitting something on full lock, (235/45/17 KU36, sounds like rim hitting LCA or chassis), could I fit a spacer on the front until i can get knuckles? are knuckles a proper fix for this and more lock?

    • Anyone want to make me an offer to take my v36/g37 3.7l manual coupe in full? Off memory it was low 100k km but the battery is flat so can't tell right now. What's wrong. I had engine problem's that led to a nice clunk. It made it home but it wasn't pretty for the last few kms. Happened under revs. Sounds like bottom end.. never got around to fully checking or fixing it so the car has sat still and unregistered for a few years. Minor bump in front end set the pedestrian protection under bonnet airbag off and that was meant to be repaired, but while waiting for the repair (parts to come) I got the engine problem. The rest of the car is in decent condition. All drive line is good. All interior is good. Leather interior. Wheels in good condition and decent tyres although the ps4s are likely a little too old now it's sat still. Colour of the car is pewter off memory, the dark grey colour. In Camden NSW. Would need a tray back pickup.

    • I started with the above in my head too, and I might be reading / thinking about what they want wrong, which is why I complicated it a bit further. Purpose I'm seeing is for the corner indicator to be on with headlights, and then if the indicator turns on it can still flash. The relay part above I can see working as required, except in the case of headlight is on, and indicator is on. The change over relay you've wired in would get signal from the indicator, and as it flashes would give power to the globe from the indicator, but as it flashes off, power comes from the headlight, which would cause the indicator to be constantly on when headlight is on, even while indicator change over is flashing. That is unless we don't care if it flashes or not if the headlight is on? I guess that's an OP clarification.
    • HI, Ive got an r34 gtt sedan A/T. The instrument cluster went out and I replaced it with another A/T everything visually looks the same and all the gauges work now with the exception of the speedometer and odometer. The speedo will stay pinned at zero until I'm going about 55kmh and then it'll say Im going about 5kmh. my odometer seems to be tracking at about a 1/10 of what it should. If I go 1km it'll say I've only gone 0.01. Appreciate any and all help. Ive tried searching through the forums reddit and a local fb group. The only info I think I've found is that some cars didnt come equipped with TCS (mind is) and the clusters may be different between those? I've also installed a brand new VSS and no joy obviously. TIA. 
    • what speedo healer did you use?
