any advice from you track warriors on fixing braking too early and winding up lifting before corner entry? i think a big part of it is that I lost brakes the last few times on track, which has made me nervous in braking. the X brakes i have should be way better, but on track actually i didn't notice a TON of difference, and the pedal doesn't feel unbelievably firm or anything, which is what i was hoping for. i think it did improve on street, but maybe i already got used to it

rt615k+, which i hate, on 265/35-18 ce28n's, with st43 pads in from, girodisc s/s rear. running castrol srf, so i should be on a bulletproof no brake fade setup... but the pedal still feels like it'll go an extra quarter inch down than i'd like once they get some heat in them.

A few things/questions:
- The X stuff isn't going to be earth shatteringly better. Moving to a larger disc will help stopping power a bit but the bigger reason to do it is the thermal capacity.
- I'm surprised those tires are screeching like that. I've not driven on 615s but I'm not sure I want to either haha.
- Are you using titanium pad shims? If so you will lose a bit of firmness in the pedal.
- If all you've changed is the calipers and rotors it's not going to make the pedal any more firm than it was before.
- Were you experiencing any brake fade at ABCC?
- Were the calipers rebuilt recently? Be sure none of your pistons are seizing.
- Are you sure what you experienced was brake fade and not pad knockback?

yes i am using ti pad shims - i'm curious as to why that would make me lose firmness though - i had a big issue with a set in the past but that was when they weren't sitting flush against the back of the pad
no brake fade to speak of. calipers were rebuilt very recently, over the 2017-18 winter i rebuilt them, then earlier in march or so i believe because the high temp dust seals were leaking, switched to oem with no issue since. i'm not sure what i'm experiencing is not pad knockback, i assumed that would be something that i could feel distinctively through the pedal. this could all be nothing and i just need to man up and go hard on the brakes and see what happens. brake harder, deeper, and stop lifting before the corner

If you doubt that you're not braking hard enough, you're probably not lol. Pay attention to braking markers and try to push a tad deeper each lap.
As for the titanium shims losing pedal firmness, I'm not sure how true it is. I ran them on my stock calipers as well and never felt there was an issue with firmness but I also never ran without them. But as far as science goes, the metal will expand as it gets hot (and it does get hot, mine were heat colored) it will get compressed a bit as the cooler pistons push on them. It's only going to be a couple thou at most though so I wouldn't think that'd make for a huge impact on pedal feel.
If it's knockback it'll feel like you have no brakes for some of the initial pedal travel, kinda scary if you don't know it's coming. Often you'll see guys tap the brakes before going into a braking zone. The initial tap takes up all the slack in the caliper from the knockback and then when they go to use the brakes for the braking zone they won't lose any pedal travel to taking up that slack.

actually - i did notice the lower bolt on both my calipers was not very tight - not loose, but it did not take a lot of effort to loosen them. that maye have contributed a little. i'll consider the antiknockback springs the next time the calieprs get rebuilt, and i just had the rotors cut. going to rebed them in once everything is back together and it's not 20 degrees outside lol. again though, could all be nothing - i'll pay more attention the next time i'm out there.

Was going through some videos last night from previous years and decided to upload this one. Shows how fast crows is, I couldn't run this thing in 2nd gear because it was all over rev limiter. The back sweeper was just a bit under 90mph. This was also back on stock block, stock turbo in 2015 Crows Tour. I did get the win that weekend, so was certainly a good weekend.
