96' 240sx front knuckle mod questions.

Crazy Drift

Driver
So I'm tired of stock steering angle. I'm always full lock when I slide and i need more steering angle for several reasons.

I'm looking at the PBM kit and I know I'm gonna get it, but while I'm saving up money for it is it worth it to have Harry from Ter-Tech cut and mod my OEM knuckles? I know it will give me the same effect I'm just a little hesistant as to if the moded knuckle may fail at an event at the weld point. I'm not saying Harry doesnt do a great job cuz I know he does cuz I know several ppl who have had him do it. So how reliable is it? And how much did he charge?

Also what other parts do I need to get(tie rods etc...) to make the moded knuckle work right so I can get more angle.

Any info or tips are more than welcome. Thanks:bigthumbu
 
Unless you want to go crazy low I wouldn't waste the money on pbm. The only thing better about theirs over Harri is the roll center correction. They are just cut and welded like Harri so just as likely to break (unless you are going to wait for their forged single piece ones to come out).
Other mods are going to depend on a few things I would get tie rod spacers at least. It is advised to get stronger tie rods since yet will be threaded out further so easier to break or bend. But you don't need them. also extended lower control arms complement nicely so you an run more camber to balance the positive camber gains at that kind of steering angle. Also you might have a problem with over centering depending on other factors with your car. If you do you can get offset tie rod spacers,eccentric rack bushings or mod the crossmember to move the rack forward but again none of this is needed just helps.

If I were on a budget I would go Harri knuckles, tien inners (or Pbms new ones) spl ends (roll center correction) and pbm spacers.
 
I have harri's knuckles and i love them. Ive only had them since curacao and but no sign of problems i know of a few other people who has had them for longer and no problem has well. honestly i woulndt. waste my money on pbm.btw i have meagan inner and outter tierods but i just bought the new pbm inner tierods for $80. i would def spend the money and get some decent inners and outters

I run MA motorsports awesometron 5000 spindles. My wheels turn like really really far. All that drift works and pbm and whatever else crap, is crap. Majority of people are goin back to traditional style modded knuckles, cause all that fancy crap, was just a gimmick.
 
only 5 things you should consider when choosing knuckles
-weight
-ackerman
-over centering
-bump steer
-safety

so as long as your not super low and they are welded properly and not going to go over center then they are pretty much all the same save for overall steering angle and ackerman!
 
and also, you dont want zero ackerman.
zero ackerman will cause very poor self steering and you'll be chasing your steering wheel around like crazy.

If your rack isnt moved and you have more than like 50* of angle, its going to overcenter.

Dont be fooled by those offset rack spacers or tie rod spacer things. Those are just like begging to have things break. rack, tie rods, that kinda stuff.
 
That's not true at all you won't have over centering problems at over 50* depending on caster.
As for zero Ackerman thats not true either most people do like zero ackerman or very close to it. Most of self steer is do to caster not Ackerman
Also how is offset rack spacers asking for things to break. Yes offset tie rod spacers are and most company's selling them will even tell you they cause problems and should only be used if absolutely needed
 
Ackerman does affect steering feel and the problem with the offset rack spacers is it introduces a bending force on the rack shaft where as before most of the force was along the shaft. Is this enough to break the rack is what the question is.

The PBM offset rack bushing looks like a good idea though.

modifying knuckles to only get 50* of angle would be stupid.....so therefore, you're gonna overcenter with normal knuckles. I run 8* of caster....still overcenters. Granted I get a lot more than 50* of angle, its still true. If you dont move your rack or use sketchy offset rack spacers, you're gonna have overcentering issues with any decent knuckle.

Idk, ask the people that have broken racks do to offset rack spacers. You ever seen a rack cracked/broken in half from not wrecking. I have from offset rack spacers.

Zero ackerman will cause poor self steer. This is a proven fact. Thats why every FD car has ackerman.

I wasnt just making things up when I posted that. Its proven facts.
 
ter-tech is his shop was in lake worth recently moved not sure exactly where anymore though you would think i would since my car is over at his shop right now.:ugh:
