Beyond extra lock

Just thought Id throw this up here again..............

I started looking into extra (extara extra) steering lock and on the DW site I found a load of stuff about it. It started off with people on about steering knuckle mods that were a DIY solution.............

It went along the lines of chopping the part of the hub where the steering rod attached to, taken an inch or so out and rewelding it as in the picture

Now the only thing that was wrong with this was that the ACHERMAN angle could and was getting messed up........like this

The trailing wheel and leading wheel angles are completly out

Now I had'nt a clue what acherman was either so this will help explain it

Now in japan they've been (D1 driver) developing hubs that have the steering knuckle position slightly altered. This works really well but they are pretty expensive.............so another bunch there developed the following kit that I reckon could be DIYed at home or even bought as they're cheap enough.

Static angle as measured on shop guage from center to lock :
MAX Super angle kit = 1.25 turns & 52 degrees
OEM = 1.5 turns and 36 degrees


This page has all the info on it, tests etc.....

S body's :rolleyes:

lol

Serious bit of kit there! £££ :eek:

Those kits are pretty cool, Ive been thinking of getting a set sent over. For $250 its not that much for the extra lock it gives.

Cutting and rewelding the knuckle looks the job but you really need to know your stuff welding something like that made from cast.

@ roco: how much would be it be to have a knuckle modified like that?

Re-welded knuckle vs. DW hub/max angle hub

Having the tierod bolt on at a point below its origional hole (like in the pics) has a big advantage.

When you lower your car, the car/steering rack goes down, compared to the hub, which stays put. This means your tierod is reaching up for its origional bolt hole,
so on the last half turn before you hit the lockstop the.........

Steering rack moves the same distance as it normaly would, but the tierod pushes up the way at an angle (opposed to out as it should)
Having the tierod go up at an angle also causes bumpsteer.

The Driftworks/max angle hubs get more lock with less steering by lowering the tierod/hub bolt point, which means the tierod comes out near straight and this also reduces/eliminates bumpsteer
