Yeah, you're gonna have to make them yourself. I would look into it but there doesn't seem to be much interest for the fd. Also from an engineering standpoint the cut weld spindles scare me. It puts the welds in shear rather than tension/compression like mine do. It appears people have had good luck with them though, we will have to see how mine hold up.

J.T.P. 10-29-08 10:58 PM

as long as it's cut/welded properly there shouldn't be a problem.. i've dirty dropped each front tire pretty hard at willow, slammed into tanner during tandem, and neither have broken.

i'm looking forward to trying yours out though, it's definitely an easier attempt at what seems to be the same thing.

chwkrx7 10-30-08 09:42 PM

maybe this is a stupid question, but i'm trying to wrap my head around a few things here.

This would throw toe out and require a re-alignment wouldn't it?

I'm N/A, so i won't be doing any spindle modifying. I want to put spacers on my inner tie rods, so am I going to need a re-alignment afterwards? Something tells me this is a retarded question, but my brain is dead. Lol.

What i don't understand is how does this give you more angle? Wouldn't you just have to adjust the tie rods to compensate for the spacer, and then you're back to square one again? Someone please explain this?

Oh and btw I'm running 16x7 +16 wheels up front with a 205/45 tire :)

Turbo II Rotor 10-30-08 10:48 PM

The inner tie rods bottom out on the rack to stop movement. By adding the spacer you're moving the bump stop out and allowing more lateral rack movement. Yes you will need an alignment after and you may have to cut a couple threads off the inner tie rods.

chwkrx7 10-31-08 12:18 AM

oh ok, that makes sense. thanks man! :)

RussTII 11-03-08 04:39 AM

we can soon have S-chassis-like angle

Oun 11-03-08 08:02 PM

you would get more swaybar clearance by running lower offset wheels right?

Turbo II Rotor 11-03-08 08:13 PM

Yeah but I have 16x8 0 offset wheels now. The wheel is just barely touching the swaybar. I'll remove the swaybar and throw in the steering rack spacers I have and maybe add a slip on spacer for a couple extra degrees.

Oun 11-03-08 08:18 PM

wow that sounds beast. your gonna have to post pics when you get all that stuff put in too :)

Wezzmo 11-03-08 11:51 PM

if you hit the swaybar one way, you'll hit the lca when you turn the other way..

i had 17x9 -7, and it hit the lca and swaybar badly

dkwasherexd 11-04-08 12:12 AM

remember every 25mm is about one inch. t2 rotor has 16x8 0 offset, wezzmo has 17x9 -7 the extra inch is another 25mm wider making it hit the lca and swaybar easier. Minus the -7 offset. I would just find some 1" spacers and add abit of camber..
The wider wheels you run the more Neg. offset youll need to clear the lca and swaybar, especialy if you have mad steering angle. Then you will also have to take the front fenders into consideration to make the fitment and angle functional.
I wish the front LCA was longer.... Its pretty short..
Numbers numbers lol

Turbo II Rotor 11-04-08 03:12 PM

I have about an inch and a half of clearance between the tire and LCA. Sway bar is coming out asap.

i found that if you go much wider than 17x9 -5 with 215/45s you start getting issues with the wheels hitting on the kit/guards, as it has such a wide scrub radius. (think thats right?)

really need 40 profile tyres..

dkwasherexd 11-05-08 01:16 AM

well, to give a close idea, this is my 215/35 on a 9.5wide .The smaller sidewall gives it more stretch, plenty of clearance from rubbing! :) can actualy have the rims come out of the body while the tires inside the fender. Running at 70psi, need alot of psi to hold air.Running stretch lets you have more NEg. offset=more angle. Im guna have this pair in the front when I find another wider pair of wheels for the back. Attachment 705154
Im might try out t2 rotors spindle mod when If I can haz money..Il also need to get the mazdatrix angle kit to work with the t2 rotors mod am I correct?.. damn angle aintt cheap.. For now im just stuck at tierod spacers...

chwkrx7 11-05-08 10:09 PM

^^ those must be a HUGE pita to get onto those wheels.

dkwasherexd 11-06-08 01:29 AM

Most shops use a cheetah....some backyard home garage guys use the starter fluid method..

J.T.P. 11-06-08 01:13 PM

cut a piece of hose, wrap it around the wheel in between the lip and bead of the tire, cut to size, the spray a little tire lube, and fill.. easy and safe.

on my ame wheels i had at sema last year, i had a 215/35/18 on a 10, suprisingly they didn't even need the hose method.

dkwasherexd 11-06-08 02:10 PM

damn i never knew about that method,its alot safer than cheeta and starter fluid method for sure, Ill have try it next time

7syawedis 11-06-08 09:19 PM

the only wheels that ever gave me troubles were my rpf1s, i even went up to a 245 but it didnt help much. i filled in the gaps with tire lube goo, about 4 handfuls total and it sealed it enough to pop the bead. it makes a huge mess though when it pops :lol: it shoots everywhere, its pretty funny really. but most of it you can put back in the can and reuse.

anyway good work at least thinking of doing this with the fds. now i should actually read this thread and see whats going on.

Here is what the stock knuckle on the FD looks like. I have a few ideas to make it better for more angle.

1st option: the same as the FC mod.

Attachment 705159

2nd option: Welding a drop piece of metal to the spindle and drilling to hole thru it. One for super angle and the other slap YO mama max angle. It would also correct bumpsteer on hella dropped FD's.
Attachment 705160

3rd option: Drilling the spindle and re enforcing it with 1/4 plates on each side. May not work because of the drop angle the OEM mounting point is at.
Attachment 705161

Let me know what you guys think. I have an extra set of knuckles I want to mod.

Turbo II Rotor 11-07-08 06:09 PM

2nd option, the arm is on too much of an angle to properly gusset, and drilling a hole through the arm would significantly weaken it. I would have the stock tie rod hold drilled out to remove the taper and get an appropriate sized bolt and DOM tube. Put the bolt through the tie rod hole and put the tubing over the bolt and weld it all up to the arm. Get a 1/4in plate and drill it for the OD of the tubing and weld that and figure out something for the other side upright brace.

ballinnmiami240sx 11-07-08 08:10 PM

This is what I was thinking on option#2

http://www.gtfactory.jp/cms/e107_fil...4_p1030221.jpg

this would give you an option for how much angle and would correct bumpsteer.

Turbo II Rotor 11-08-08 02:51 PM

They look as though they have been machined out of a solid block. I say pick up some 1/2" .250 wall DOM and a hole saw to notch it and a tap.

I didn't weld them, I don't have a tig. The guy who taught Jeff from Fullrace how to weld did those. It's amazing what that guy knows and can do.

What's the point of moving the tie rod mount in? Doesn't that mess with your ackerman?

J.T.P. 12-09-08 07:19 PM

depending on where u move it, it may... but ackerman isn't always that good for drifting.. well the amount from the factory anyway.. but that's all personal preference.

after months of waiting i finally got my modified hubs from turbo 2 rotor. they look great and ill post pics when i get them on my car. i suggest everyone get a set. jtp is rocking these as well.

the long wait wasnt t2r's fault and i was not in a hurry to get them so dont let that scare you away from doing business. great workmanship and a great deal

Oun 01-21-09 07:08 PM

very interested in knuckles for the FD. please pm me or a kitten dies!

true.

i haven't had a chance to throw them on though, since the car JUST got out of paint.. i'll be putting them on when i get back from michigan along with a couple other little things i need to do to the green car. then i'll get it aligned and test em out.

These should be a real good setup for those who like drift AND grip, since the original pickup point is retained it would just be a matter of switching out the through bolt with the taper bolt and re-alignment.

when in action i'll get some pics, and report back.

btw, thanks again Scott!

the whole point of making that much angle is so you CAN hold it there... adding angle allows you to add more throttle, since you can slow the car with angle, this allows you to add throttle to create SMOKETOWN!!!

RE TurboII 01-22-09 11:48 PM

your car reminds me of kermit the frog in a weird but hilarious way

ElysianD 01-23-09 05:56 PM

Are FD and FC tie-rod ball joints the same? or same taper at least?

J.T.P. 01-23-09 06:27 PM

i think the FD ones are a hair smaller... anyone correct me on this?

USS CJ 01-23-09 06:48 PM

Just jumping my old car from 225 and my new car to 325, there is no way in hell I could hold that unless I was running more power. Maybe I'm just not used to them yet, but I'm going to redo my old ones and change the mounting point angle for the tie rod and start running them there maxxis tires, or maybe some 595rs.

I am worried more about hooking up and losing the drift than blasting into the wall backwards :lol:


Yeah,

The biggest thing id think about is that youve never driven a drift car before.

I wouldnt worry about angle until you even drive.:hahaha:

No they are different, the taper is ever so fractionally larger on the FD, but enough that you cannot interchange the two.

USS CJ 01-26-09 12:51 PM

Thats cool dude. I guess I just missed seeing you at every event for like 3 years lol.

lol gotta love those china men wannabeezzz that knock stuff off here in the states :scratch: about the whole what and measurements i have no idea. i used to tig weld for Neukin Motor development so the welding part isnt my issue its the geometry of it that puts me in fail mode.:Wconfused


the only person who i talk to that drifts subarus is running fc spindles lol so it is no help. then there is a guy in russia that did his sti spindles but i cant get anything out of him. Obviously there are more people that have done it i just cant find jack right now.

pretty much just need more angle and lots more caster and camber
