i have a GTR rack in my GTST and compared to my other GTST it feels more responsive and lighter to steer i think, or it feels that way to me is there a difference between the GTR rack and GTST?

Also when i ajusted my Castor rods to about +7 degrees it made the car a lot more responsive and faster to steer with so mabe you could try getting a wheel aligment shop to try that?

Yeah castor definetely helps, I have mine set to maximum with the Whiteline bushes.

Not sure if the GTR one is any different?

A good example is watching JGTC interior video clips when they race. They barely ever go more than a 90 degree turn of the steering wheel.

Also keen to know this, the r33 ratio is pretty slouchy imho.

I had a v35 (basically a 350z lol) before the 33 and the ratio was much much better although strangely enough, i have better response in the r33 lol.

Will be keeping an eye out for info on this topic.

Wait up i'll go try and find the printout.

EDIT: Ok I think this was the last one I had done.

Castor I have set at +7.45 left and +7.14 right.

Front camber I have -1.52 left and -049 right.

Toe on front I have +0.04 left and right. So should I pull this in a bit?

Toe on rear I have -0.04 left and right.

Rear camber I have -1.37 left and -1.32 right.

what about modifying the knuckle where the tie rod bolts on.

maybe use an extended rack arms with longer tie rods and move the tie rod mount lower?

has something to do with ackerman angle????

have a read

i know this is all for s1x chasis but might be worth a read

maybe email nigel petrie about modifying a set for an r33

you want lock like this ?

Well I might try playing with the front toe and getting the right camber the same as the left (no idea why there was such a variance) and putting new bushes into the steering rack and see what that does.

I would love a smaller steering wheel but I want the factory airbag. I have looked into a few options and I will have to sort something out with it one day.

Thanks for the link Rob! Will do some reading, seems very interesting.

my advice if you want sharp steering and for the car to feel more 'pointy' you can get most of it with alignment. bushes will give you some castor but adjustable rods will give you a lot more. get some adjustable rods and run as much castor as you can whilst still being able to run 2-3 degrees neg camber. as for toe if you really want it to turn hard and fast you'll need to run some front toe out. keep trying a bit more at a time till you hit the sweet spot. with a decent amount of toe out at the front and a fair bit of caster you'll be amazed at how different it feels.

BB is right. If you want good turn in and a more direct feel, run more toe out on the front and more positive castor. If you want less steering input for more steering angle, you need to reduce the ackermann by modify the knuckles

FWIW here's my front end setup.

Camber: -4

Castor: +7

Toe out: 6mm out (total) 3mm each side.

Moddified knuckles. 3 turns from lock to lock.

Offset steering rack spacers.

Ikeya Formula tie rods and tie rod ends.

Cusco castor rods.

Cusco front upper camber arms (5mm shorter)

R33 LCA's with modified lock stops.

Whiteline 22mm S/bar set to soft.

Tein coilovers with dampening towards the softer side.

Pics for reference.

Yeah they're the rack bushings that hold the rack in place, I'll get some of those soon.

With alignment, if your car is track only then anything goes, if your car is street then too much toe/camber/caster absolutely eats tyres in a matter of weeks.

I did check out some steering quickeners, but they're all universal and difficult to install which requires cutting and welding, and cu/shut anything in suspension (or brakes) is a big no-no, and very hard to get engineered (IE be safe).

Any body know much about those?

yeah they are just replacement steering rack bushes. they hold the steering rack to the subframe. no point replacing them unless the current ones are stuffed. I have those nismo ones in my 32. they are stiffer than standard so I guess add some 'directness' to the steering feel. that also means they will transmit more vibration etc but it's not a big deal. won't do anything for how the car turns etc (unless the old bushes were so stuff that the rack was moving).

    • Are you suggesting that the kit did a cheap and nasty job of just jamming the wheel in between other things and caused the misalignment? I mean, we normally do this with an integrated crank trigger wheel, not something bodged on. It's not 1995 any more.
    • I mean, given the number of BMWs you own their tolerance for improper torque is rather low. The number of torque + angle spec bolts and non-reusable bolts in one is nuts.
    • Atmospheric vent requires something that doesn't use a MAF for load. You would need a standalone ECU for that.
    • Hey all,   I’ve got an RB25 with a trigger kit that includes a crank wheel, and I’ve hit a wall trying to sort a timing belt tracking issue. The belt either rides right on the edge of the cam/crank pulleys or walks slightly forward once the engine starts. It tracks okay-ish for a moment, then creeps right to the edge—and honestly, it’s stressing me out.   I’ve spent hours removing and reinstalling the belt, double-checking everything:   Tensioner setup is good, checked multiple times Idler pulley and washers are all in the correct places Followed the RB25 timing procedure step-by-step     The only thing I changed was the rear crank washer—I swapped the OEM one for a Neato version, and it made things worse. The belt now sits even more forward than before. I’m beginning to think the crank trigger wheel itself (from the trigger kit) is the issue—poor design or slightly off dimensions.   What’s strange is that with the previous belt setup, it actually ran fine for a couple of years—around 4,000 to 5,000 miles, even with hard driving and high RPMs. But even then, the belt was always riding right on the edge, and I know that’s not ideal or safe long term.   At this point, I’m debating whether to:   Machine a few mm off the crank trigger wheel to bring it back in line, or Replace it entirely with a better-designed unit     Only thing is, I already have the Cherry Hall sensors, bracket, etc.—I just want to replace the wheel only, not the entire kit. Anyone know a brand or supplier that sells just the crank trigger wheel on its own?   Would really appreciate any feedback—especially from anyone who’s run into this exact issue and found a reliable fix.   Thanks in advance.
    • Hi...a little refresh. Is Nistune gonna be enough to run BoV? Or do i need some proper ECU?
