custom steering Knuckles and getting max lock

[Robo86]

I feel we need out own place to talk smack about steering knuckles.

Ok, i bent a power steering arm last week, and since i have to replace it i thought i might try something new.

There are a fair few different ones floating around now:
Techno Toy Tuning (T3):

Garage Clear V3:Vid

3Up: Expensive! but nice

Hibino's (not sure on name sorry, but JESUS he has some lock):



"With perfect Ackermann, at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point. Note that this may be difficult to arrange in practice with simple linkages, and designers are advised to draw or analyze their steering systems over the full range of steering angles."

Ive found it pretty hard to get feedback about the whole Ackermann thing, mainly because theres just about no one in Australia with modded knuckles in AE86s (hi ken ).

The silvia guys have been playing a fair bit in Aus, with reports of "improved corner speed, front grip and an overall gain in "snappy-ness".

Theres also the safety/legality side of things, they are welded after all .

I already have bucket loads of lock (ps arms, extra lock rack ends and long tie rod ends to support) but i think if i go for a knuckle like the ones above, the inside wheel will hit the castor rod? (i have about 2mm clearance on lock now). I know the solution is less wheel offset/ spacers but its not do-able for me atm (5-0 fail).

i wanna type more, but i cant think of what atm/ in a rush. will add later!

Lets have a discussion....... GO!
HIBINO!!!!!

yeah a bloke round my way modifies knucles to improve the ackermann, i've heard good feedback, don't run em personally but if mine fuck up it's what's next

[driftke70]

ill probably machine some up if i can be bothered otherwise just get something stupid like hibinos

Recently got Garage Clear Vol.3. In car and steering around the street at slow speed and did some crazy turns and such. Obviously made my steering heavier but It felt ALOT heavier.

Need to try it at speed/when sliding.

Did you try those knuckles I did for you.???

[Robo86]

I modded my knuckles in my R31/HR31... pretty crazy angle for a 31. Also had ikeya formula rack spacers in there too.



I did have P/S arms with a AJPS lock spacer in the 86, but have since removed them for a new setup...



I was simply going to replace them with the T3 setup, but I think after looking at hibino's car on lock... i wanna make my own el-retardo hyper-mega-super-lock knuckles and tub the front end at the same time

P.s Arm VS Redworks modified Arm, Ackermann change but same length as ps arm (as i requested)

[ae86]

what about pics of hey-man knuckles, see alot of cut and shuts on yaj

i have custom 86 knuckles in my ae71. they have ackerman correction for drifting and are slightly shorter than PS arms. i dont have any rack spacers though... yet
i havnt had a good skid session with them but seem to hold big angles and feel a big heavy at low speeds but that doesnt concern me. i will give better feed back once i get a proper drift session in.
