But the biggest thing, and the thing I need help from you guys with is that I think I am getting bad pad knockback. There is a very fast left hander (110mph apex) straight into a braking zone (bus stop) where I went off twice because when I pushed the pedal it went ⅔ to the floor and the car didn't stop. Car stopped just fine every other corner, though I was consistently getting freaked out and adjusting my brake zones back, only to have to accelerate back to the apex. Urgh. Learning for me there is to either tap the brakes (but honestly, that's hard to do as I need the weight on the rear to keep it planted around that corner), or to push the pedal until it stops, as what I was doing is pushing the brake down the same distance. Beginner driver move right there.

Took me 2 offs to realize what the shit was happening. So, I'll start another thread on knock back I think. I imagine the carbon brakes won't help. Maybe need new wheel bearings? Surely I'm not the only one hitting this issue..
 

 

I see the stock brakes still on the car.

 

The RacingBrake brakes are more resistant to knock back I found.

 

But wheel bearings could be part of the issue.  I did new ones as preventative maintenance.

Hey Shawn,

Good to know! It took me quite a while to save up for the replacement front rotors for your brakes. They're on the way to my house, or there, will check when I get back from traveling, and get them on the car!

Any other advice? Did you ever have to pump the pedal on track with the RBs?

Never had to pump them.   Ever.  The pistons stay where they are unless the rotors are pushing back.

Sounds like an awesome day, Dave! I love Peter’s car - very very jelly!!

As for the mental focus, yes - you have to always always always be thinking around the next corner, the optimal line, and force your vision to stay glued to that line. DO NOT ever look towards a wall, a sand trap, the back of the car ahead, etc. It’s very very hard to do, but learn to ignore the noise and focus on the result, it’s a key to going fast.

There are two quotes I’ve heard that explain this very well.

From one of the Nismo Academy directors “ If you think you are going off just look for hope, not reality”. He means literally LOOK with your eyes for the safest thing to hit, the best possible outcome.

From the book Racing in the Rain - “The car goes where the eyes go”

Anyways, you have to push the limits in order to get faster - keep on doing what you’re doing buddy!

Cheers!

Thanks Wes. :D  Always fun.

 

Both those quotes are money, and the ignoring the noise piece are money, but man, so hard to do.  Need more seat time.

 

Car is gunna head back to Nissan for wheel bearings and a bit of trim replacement next week, will give me time to swap the hats over for the new fronts and then on with the first major upgrade on the thing.  Super excited!
