Ice mode solution?

thekinn

Can you make any recommendations for us HPDE, street tire guys? My first thought was the RS14 front and RS4-4 rear on a 4piston front, 2piston rear 350Z. A friend suggested RS19 front and rear.

this might be a fix, it mentions that with this BBK system, you do not have to worry about ABS Freezing "Ice Mode" ....ABS 誤動作. it says this brake system re-adjust brake bias to its optimal.....so i guess we can officially agree that ice mode is a result of brake bias?? (this is coming from NISMO official website) then if this is true, then playing around with different brake pads F and R should help determine what is best setup....but i still see lots of ice mode complaining even with numerous changes on brake pad setup.

I bought my 09 Z couple months ago planning to make it a dedicated track car, but obviously without much research.

1. 1st problem noticed was oil temp, i ran into limp mode while doing some mild spirited run on mountain roads (WHY does this happen on a NA car)

2. now, i've always know that Z33 had ABS Ice mode issue but was assuming Nissan had fixed that on Z34, but obviously i was wrong.

so, unless a race ABS system is used, it just can't be tracked safely. I have 10+ years track experience and uses my brake pretty damn hard.


i'm a guy coming from S2000, NSX, EVO, and Sti; never had to worry about ICE Mode as long as i changed out pad, fluid, brake duct, and SS line....worry free.

now with the issues 370Z is having, it is going to be a costly project to safely track as the track PIC has many slow turn and requires very hard braking in about 4 corners. 2012.11/25-OTGP

sorry guys, i'm not here to bash on 370z.... i like it otherwise would not have bought it.......i just think the people that track 370z knowing ice mode may bite you and catch you off guard are brave

welcome to the forum! don't you wish you came here first?

i'm skeptical the issue is "solved" with a new set of calipers and pads... one theory is that the abs computer looks for differential wheel spin rates as its trigger for ice mode... calipers and pads will help but never completely eliminate differential wheel spin rates - also requires suspension tuning and driver input changes... the real solution is going to be new ABS software or computer

fortunately I haven't had the issue in my last 5-6 track outings... maybe something about the tracks I am on... was worst for me on short technical tracks, esp where track surface had both turns and bumps in braking zones

would encourage you to read some of the track car build journals - mine's linked below
