Any reason why this isn't a good idea for quick toe adjustments ???

I think it is a good idea personally.

That's a fairly common mod. Patrick sells it. From what I understand, it's very effective.

having welded a bunch of the patrick ones id bet they are lighter.
the dont use rod end adapters which are really heavy.

quick camber is wishful thinking unfortunately.

these setups are only really useful or necessary on race/track cars. for any street car they are totally unnecessary.

i wouldn't say that... it would depend on how much torque the engine makes. that would be a good for a v8 mod. i would think it would add some support to the outter suspension mount.

that looks like a stainless bar
ours is aluminum and a bit lighter
5 years of on track time with 2 drivers
works really well for a track car

I've been thinking of adding something like this to my 914.

I assume your comment is in reference to holding the swingarm in place during heavy acceleration/braking/cornering.

I would like to install this only for setting the toe. Every time I try to set the toe & loosen the bolts, the swingarm shifts and I lose my adjustment.

Patrick wants $320 for their system. I want to know how I can do this job for $20.

I think for big HP and big torque engines matched with fat soft tires that this mod is worthy of doing. In addition, it's MUCH easier to set the toe. You can scale the weight down a little by using aluminum rods and smaller attaching points as I did.

When you set the toe, I would suggest cranking the rod and leaving the system loaded against the load direction of the suspension. If the rods are not loaded, the adjustment can jump around in the slop of the threads. Once the camber is right, I like to gently snug the suspension bolts and then crank the rods under slight load until I get the desired toe. If you miss it, wind it back and approach it again rather than just cranking backwards. Hope this makes sense.

Hmm. I'm not thinking of what can be purchased and bolted/welded on. I'm thinking of what can be manufactured at home with very little cost.

I had a few ideas on how to inexpensively manufacture this. My latest thought involves the old tie rods I took off the car a while back and are sitting in the attic. If I can work out the mounting, the tie rods would give me the adjustment necessary to perform toe alignment.

For me, it doesn't have to be pretty, it just needs to work.

I personally believe it's a good idea whether racing or not. First off, as everyone mentioned, it makes toe adjustments very straight forward. On mine, I have a short hex section mid-tube so that I can use a wrench to make the adjustment (my heims are right and left hand threaded pairs). The other nice feature is if you need to partially drop the swing arm, it will retain the original toe avoiding the need to re-align it again. In my particular case, I have to drop my swing arm to get the inside CV to clear my engine cradle when I drop the motor/trans (V8 conversion), so this is very necessary for me.

dug out one of the pictures from my "vintage race car" thread
we removed the jack point to save weight (not rusty), and then welded in a small reinforcement on the long for strenght

here is a pic:

Carroll Smith would observe that you have critical fasteners in single-shear, which he would regard as a crime against nature...

But I don't see much of an alternative, especially for the forward welded pickup.

For extra credit, it'd be nice to use fasteners with enough shoulder near the head so you don't have threads working on the inner race of the monoball, but if it's torqued tight there shouldn't be any motion there anyway.

I did the mod on my six conversion. Maybe a hinged rocker panel for quick adjustments???

Why not? Evidently some of the factory GT's had hinged panels for easier access to the suspension adjustments...
