I'm puzzled too. I did not notice any performance decrease, but I've only had 1 day of pushing these pads. If it happened in the last 2 weeks I won't know till my next track day.

I was wondering abut stone impingement, but it happened on both left and right caliper. Low probability I would say.

 

After being on a battery tender for a while with no issues my batt is its starting to give errors so i'm looking at replacements. What made you pick this battery?

 

Lightweight, good reviews, and I actually had one in my S4 years back. I wouldn't pick it for a daily driver but as a track car, no issues. I'll store it inside over the winter

 

Ordered my rear diff cooling setup today...
Pump
Cooler with fan
Fittings
Hose
Switch

I'll post some pics once I install

 

Did you do an accusump setup? If you did please post some details. I noticed I can barely make it a 20 minute session without pushing the red zone on oil. I'm not familiar with this though.

I know there's a way to publish Harry's videos as well. A buddy of mine uses it. I'm probably going to switch over to Harry's at some point because it helps by breaking down the track in segments which can help you figure out where you can improve.

How are the Nitto NT01's vs like RE71's?

Close to pulling the trigger on Watson as well.

Also looking forward to seeing details on this.

 

I replaced my stock battery this weekend with an Anti Gravity lithium unit mounted in a Morris Engineering machined aluminum tray. The Morris Engineering tray was well made and fit perfectly. The only issue I had was with the brass terminal adaptors to connect the battery to the clamps on my car. The screws supplied were a little long and bottomed out leaving the terminals spinning on the screws. I ran down to the local Ace Hardware and bought a couple shorter screws. This combination weighed 25.8 lbs less than the stock set up.

 

Nice! Matt makes good products and stands behind them. That is a great setup, super lightweight and good power. Lmk how you like it!

I have to install the diff cooler when I get home before 8/29! And make new canards... can't wait for some fun fall track days!

 

I know what you mean about trying to get time for installs. I have had the battery tray sitting in the garage for around a year. I bought it on the introductory pricing before they went into production and have been waiting for my battery to need replacing. The factory battery was still testing good, but at 6 years old I know it can't last forever. I bought the new battery during the fathers day sale a couple of months back and just got around to putting it in.

So far so good. The machining and finish on the Morris Engineering battery tray is top notch. It bolted in perfectly lining up with the factory mounting holes and holds the battery securely without any signs of movement. It is a real quality piece.

 

How many have upgraded their radiators? Any idea how much better something like the FRPP setup would be compared to a Mishimoto?

 

Dmicheals how did you solve the small battery issue (pc680)? How did you make it fit? I bought the odyssey pc680. I need your help Yoda :-)

 

I'm still using my stock track pack aka boss radiator. Need to upgrade soon though as my car runs hot

 

I'll have to take some pics when I get home. Away on vaca

 

Ok no worries, enjoy your vacation

 

My Hankooks rs4s 285/35-18 delivered today. Pretty impressed with looks but won't have it mounted till later. I won't be able to provide feedback till Dec (Daytona)

 

Nice! I've seen one person at the track use them so far. Their feedback when I asked them how they liked the tires so far was "These tires are the S&^T!"

Hope you enjoy them too!

 

If they are anything close to hankook z214's (c51 compound) then you'll enjoy them!

 

So I have 1 good thing to report about today's track day at Mid Ohio: I live to race another day.

I have been pretty happy with my Russel braided stainless steel brake hoses, until today. After the first session of the day this happened. Fluid gushing through the wheel, pedal to the floor. Needless to say it ended my day at 8:30 in the morning and I spent the rest of the day waiting for a part, someone to dive me to the store to get the part, and then covered in brake fluid.

Disappointing state of affairs. I got braided steel lines so I wouldn't have to worry about this. Now I need a new game plan for what to do next. I got it good enough to drive home with some no-name brake hoses.

 

Also, dmichaels, I found someone with a more outlandish wing than yours.

 

I really hope that car can back up those looks!

 

man sorry to hear that 5.monster, that sucks. Hope your next trackday is better
