Hi Rick.
DeltaV stuff is really good. Nothing better and its delivered in just a couple of days too.   Square bush is available from Toyota for bugger all and is well worth replacing also.  Don't forget to check the tightness of the cotter pin that secures the crank to the selector shaft.

I've got a square bush replacement bearing coming as part of the group buy... The genuine Toyota one isn't a great concept... They start wearing from day one... Obviously trying to keep costs down. I love the idea of a proper bearing replacement

IMO that square bush is the best design for the job, cheap and easy to replace too.
On my '90 model NA I simply loosened the starter (no need to remove it) to access the bolt underneath to loosen the assembly enough to pop the square bush out.
If it hasn't been done already, simply rotate it 90 degrees, grease it and put it back.
 
"a proper bearing replacement"
You can buy an enclosed ball race that is supposed to do the job.
However I tried to fit one to my car but found it useless.
With the NA OEM bell crank assembly design, there was too much slack for it to ever work properly .

I did rotate it when i did the Beams swap, but i think the bearing is a better idea, i'll see how it goes when it arrives...

Rick,
When you receive it, would you mind sending a pic thru.  Very interested in it.
 
Cheers.

I'll definetly post pics and share my thoughts. I can't afford most of the things i want, so I'm keeping myself happy doing the little upgrades atm. It's amazing how much better the gearshift feels with just the DeltaV bearing upgrade cosidering the original bushes weren't excessively worn. All the little things seem to really improve the driving experience.

I only have the bearing upgrade.... you may have talked me into buying the DeltaV ones.

After the last track day at Mallala my front pads were stuffed.
The inside pad still had plenty on it, but the outside left pad was down to the metal. Is this common?
I might have to check the calipers movement.
Nice new QFM A1RM pads are ready to go in, and the discs have been machined :)

Good to hear the DeltaV upgrade was a success mate.  Those brake pads should not wear like that.  Check the sliders for grease and smooth surface.  No pitting or wear.
Cheers.

Sounds like your sliding calliper isn't sliding as per what @falcon said

As suspected, the sliding calipers weren't... the top slide bolt was seized. The rubber boot seems ok, but wasn't seated correctly and allowed dirt and water in. I gave everything a good clean and reassembled it with new high temp brake grease as per the bgb. Installed new pads and machined disks, so should all be good now...

Good to see your still hitting it hard Rick! I also found out my caliper sliding mechanism wasn't working after MTC 2014, brake pedal always felt a bit off
