I had DC EX -1012 tips on the stock axleback for a while, then I had a Berk dual exit muffler delete for a little while then sold it.

I've had the WORKS AB-M axleback since April: http://www.ft86club.com/forums/showp...&postcount=326

...and I've had a JDL UEL header on order for 119 days so far

@ATL BRZ what catch can are you using? I was considering the investment in one.

It's a universal Moroso AOS from Amazon: http://www.ft86club.com/forums/showp...&postcount=219

This one, specifically: http://amzn.com/B004K9BIY4

It does its job well and features an easy drain valve with a rubber stopper.

Silver oil cooler core is going back to Perrin; no reason besides color preference...



Black core is getting installed with rest of kit.




Project Mu Club Racers arrived, will be bedding them in soon for track duty




Two new 5 gallon jugs for E85 transport to the track. Test fitted them; like a glove!

Cooling down on the lift in the air conditioned shop.

She's so spoiled.

After the garage got down to a cool 70 degrees, the first order of business today was the oil change over to Millers Nanodrive CFS 0w30 NT.



Installed Fumoto F-108S oil drain valve



Added some dive mesh to both of the brake cooling ducts to keep the bugs and debris out. Thanks again @smbstyle for the mesh.




Installed Perrin Oil Cooler kit with the new black core from Mocal







I installed the kit from below with the help of the lift so I didn't have to remove the bumper; way easier just pulling the under trays off. Everything went on according to the instructions and I used high temp thread sealer on all the fittings.

First test run around the block with the cooler installed I had small leaks from both fittings on the cooler. With the heat expansion and contraction after cooling back down I guess I didn't get them tight enough so I tightened them again and wiped everything clean and went on another test drive and ended up tightening them again another 1/4 turn from the fittings and I made it 25 miles home completely dry with no leaks. Advice to anyone installing this kit just make sure you get the fittings REALLY tight and then re-tighten them at least once after a short test drive and keep those two wrenches in your car for the first few drives.

Oil temps are significantly lower now! Cruising home the oil temp hung out right around 180F in the 95 degree ambient temps that we have today where before the cooler I would run 220-230F cruising around. Previously at the track I'm certain the oil was getting to 270F+ since I could feel the timing being pulled and the car began to lose power late into my sessions in the summer heat. I shouldn't have that issue anymore! Power will be consistent all the time which makes the cooler worth it.

Speaking of power, it might be placebo, but the car does feel a little better up top with the Nanodrive 0W-30 oil in it. Miller's did measure +6whp on a dyno with the same oil but 20 weight. It should make the most power after I thin it out a little more with some track time, which is conveniently only 20 days away!

Next up is a MUCH needed wash and vacuum. She's filthy!

1 hell of an enjoyable experience driving this car on and off track.

I slapped a quick and dirty video together to review my first year of BRZ ownership in photos.

It's hard to believe I've owned this car for a full year as of today. Here's to the next year and a few more mods and MORE TRACK TIME! :happy0180:

Getting clean



Love the sud gun.

I meant to ask you; how big of a difference did the RCE Yellows and swaybars make? Any downsides to that combo? Was the car just as neutral as it was stock, or did it make it more prone to oversteer or understeer?

I find the @Racecomp Engineering spring and sway combo to be excellent on a dual purpose build. The Yellows lower the car 20mm, are 250lbs/in equal rates front and rear, and they put the shocks in the 65% critically damped sweet spot as RCE measured on a dyno. I found them to preserve the neutral handling the car came with once I corrected the camber in the rear with adjustable LCAs.

With and without the RCE hollow sways the car is very neutral 95% of the time, and it will progressively oversteer if pushed beyond the limit of tire adhesion. The sways are a great match for the springs as they benefit the handling greatly by getting rid of nearly all body roll. With decent negative camber front and rear the turn-in is razor sharp and the car is very fun on the track with sticky street tires without being too low/stiff to daily drive around town.

If it were a dedicated track car with slicks or R-Compounds then I'd go with stiffer springs on a set of coilovers so I can set the ride height lower and run wider wheels/tires. For now though I'm very happy with the car the way it is. I have some track footage linked in the first post that may give some better perspective on how the car behaves at the limit around a couple different road courses.

Better shot showing how stealthy the black oil cooler core is

[chanomatik]

I still tear up in my eyes when I see your car, even though I have a similar car with plenty of mods. haha It's always so clean! I can't keep mine clean for anything. Honestly, that's one reason I like winters in Alaska, because it's cold and cars pretty much stay clean except when caked with snow, which is easier to wash than dirt. And I have a warehouse I can dry my car off in.

Oh my. Those rims are oh so pretty. Nice ride!
