Kris' AW

[Statek]

With the house nearing completion (weeeeeeeeell… it's liveable, so close enough) I managed to squeeze in some time in the garage.

Last year I grabbed a facelift brake booster, a new 1” master cylinder from a hilux and ST185 twin piston calipers for the front. The twin pots were actually installed in November last year, but I forgot to mention that earlier.

Noticeable difference? Yes.
Pedal was slightly softer straight away (due to the increased volume of the calipers) but no biggie, and I didn’t get any brake fade during the track sessions at Toyota Festival 2015.

So now, with all this spare time (yeah, right) I decided to install the larger booster and master cylinder. My thinking went like this: if I already have to bleed my brake system because replacing the master cylinder, why not install braided brake lines? So I bought some Goodridge braided lines from RacePro in Wellington (omg, their website is pure race car porn!) and some high-temp race fluid from BNT.

Result = harder brake pedal.
Looking forward to testing out the new suspension and braking hardware this coming trackday!

Yesterday's trackday went very well.
I managed to cut down my lap times - averaging 1:27 to 1:28s (I was running consistent 1:29 around Hampton Downs prior), this isn't spot-on precise as I'm only using GoPro footage to measure. Guess I'll have to investigate a good timing app.
My best time was actually 1:25, and this was a sort of cooldown lap after I beat a V8 BA Falcon over the course of 2 laps. This just goes to show that smooth and gentle can work better than aggressive full-on attack.

Brake fade still reared it's ugly head, which now definitely means a brake pad upgrade to some race pads. Any recommendations? I'm using ST185 twin pots and this car is now mostly for the track...
I'm also on the lookout for Mk2 22V calipers for the rear

I'll upload some footage after I get a chance to do some editing.

I did manage to find this thread relating to Android lap timers: http://mr2.org.nz/phpbb3/viewtopic.php?f=19&t=11567
I'll have a browse through those apps.

I also found this post about 'occasional track day brake pads': http://mr2.org.nz/phpbb3/viewtopic.php?f=19&t=12833
Looks like EBC Yellows seems to be most recommended. I also recall Simon (85AW20v) uses Remsa pads on his factory (facelift?) brakes - they had really good stopping power and he doesn't get fade.
Any comments?

In-car footage from Uncles Club - straight footage, no editing.

The first session was fairly tame, used it to familiarise myself with the new setup.
Session 1: https://www.youtube.com/watch?v=XET3ciqtDas

I got stuck behind an Altezza who was hogging the track - nearly ran me off on to the grass, so I backed off..
Session 2: https://www.youtube.com/watch?v=LyJR2uFZ5jo

2KCup Bluebird and BA Falcon V8
Session 3: https://www.youtube.com/watch?v=ZqToTKDZ3Ts

Relaxed cool down session, this one was shorter then the rest as it was the last of the day, and it ran until 7pm.
Session 4: https://www.youtube.com/watch?v=8LsNN5OMF4Q

Enjoy!
Constructive criticism is appreciated

Part of the reason for me running the ae111 twin pots over the celtics singles is after a lengthy conversation with the guy at race brakes.
With the 2K cup being a huge hit and the ae101 and ae111 rollas being hugely popular as a winner it's brought about a wide selection of tested pad compound options for that pad backing plate shape.
I'll be running endless maxis pads all round.
As they also come for celica rears (popular in rally)
That and racebrakes fluid
The pad size is actually bigger then the woolwood 4pot pad, only benefit to the woolwood set up is less unsprung weight and better heat distribution due to larger disk area

Nice posts, looking good out there

Tried Znoelli 500 series pads with TRD fluid Kris? Both available from North Shore Toyota.

I'll look into these, thanks Charlie!

Hmm, brake pad size not a direct contributor to performance in my understanding.
A quick search reveals a Wilwood page to answer a thought about this:

Q: Will larger brake pads improve my stopping distances ?

A: Not necessarily. A larger pad of the same compound in the same location as a smaller pad will not yield shorter stopping distances. The amount of pressure applied, the pad friction coefficient, and the diameter of the rotor at which that pressure is applied, determine the torque reaction, or stopping force. A larger pad does not apply more pressure, only the same pressure over a bigger area.

The size of the pad does matter in terms of heat capacity and wear rate. A larger pad will absorb more initial heat, hence less thermal shock, and have better wear characteristics resulting in longer pad life.

Rotor diameter in mind is a bigger contributor to effect than pad size.
I'm certainly VERY happy with my wilwoods, having run: prefacelift, facelift, st18* celica big single pots, st185 twin pots. All for reasonable amounts of time to get a good feel for them. Wilwood street pads still take some light driving to warm up but blow the rest away in comparison to how they pullup.

Got around to clearing out the garage. Now there's finally room for two cars!

[flying_wedge]

Since when did you own an SW
Adub's looking good though. Any further thoughts on a repower?

Since when did you own an SW

haha, about a week? It's a fix up I'm hoping to use for a bit. Just a NA auto t-top - nice for the summer. Since coilovers went in the AW, my wife doesn't like using it for long drives

Adub's looking good though. Any further thoughts on a repower?

Still thinking down the same path. Trying to squirrel as much money as I can away from Christmas
Last time I had it out for a spin, it smoked a bit, so a re-power is gonna happen sooner than later. Fingers crossed soon™

A weird squeak has developed in my AW when just driving normally. Went through the whole interior trying to identify it, and found that it must be coming from outside the car. Checked my whole suspension and couldn't pinpoint it. The cat walked over the engine lid one day while I was doing other stuff and I heard the squeak again, so I re-adjusted the rubber bungs thinking "Sweet!". Test drive proved otherwise. Bugger.
Not being able to climb under the car properly while it's on jack-stands, I drove to my old workshop. During the drive there the squeak was horrible and something started slapping on deceleration. I now had a funny feeling I knew what it was...
As soon as it was on the hoist I removed the under-tray covers and took the front engine mount off to find the cause of my trouble

Being a Saturday, the boys wanted to go home, so a quick weld to get me going.
Need to look into those strenghtening plates which are welded to the chassis. I've been talking to Alex about them for a while, now is the time to investigate and make some up (yes, they can be purchased from TechnoToy Tuning).

In the meantime I also fixed up the SW in my garage - cooling issues, oil leaks, fuel leaks, idle problems and smoking from exhaust all sorted. Even gave it a vacuum and wash. Just need to replace a rack-end and take it in for a WOF.

Finishing off the thread, for the sake of completeness...

Late November, I finally got around to installing the 22V rear brakes I had lying around.
You can read more about it in this thread: http://mr2.org.nz/phpbb3/viewtopic.php?f=12&t=13883

Around the same time, I addressed my front engine mount which I had suspected had perished. The plan was to replace it with a urethane type mount, but needed something quick to stop wear and tear on other parts in the meantime, so got a second hand one.

..and the sad day came, when I finally decided that it wasn't worth keeping the car garaged and unused.
I didn't use it daily, as Auckland traffic is bad enough to make you not want to drive a manual (I have to travel INTO the city in the mornings which takes around 1 hour in bumper to bumper traffic) and didn't take it out on the weekend often enough as my wife's back couldn't handle a) the suspension, and b) my driving.
You guys can blame Speedhog for letting me drive his car on dirt, which pushed me over the edge into wanting something usable on gravel, and something which I wouldn't mind thrashing and the occasional accident wouldn't make me feel sad.

After serious debate, and some mad photoshop skills:

...I had decided that the yellow car will remain in it's current guise, and someone else will be able to finish it by finally doing an engine swap and making it go faster than it's ever gone

The car has now sold to a forum member (who I hope will keep his thread updated with future upgrades and mods). Who knows... maybe I'll buy it back one day
