FM2 clutch won’t hold past 18psi

So what next....ACT XT 6-puck? ZM2-XTG6 // Advanced Clutch Technology

 

where on that video does it start to slip?

 

3:22 & 8:21

it slips on 5th gear

 

 

Can cold rain do this on track?

 

Unless you're drowning them in liquid nitrogen after each session, I'm gonna say that's not healthy. TSE 11.75" kit?

 

Those cracks! Before this, did you get vibrations when you stepped on the brakes?

 

wow that looks scary

 

That's absolutely terrifying. Glad no accident happened as a result.

 

yes

Didn’t feel anything different. Only weird noise every time I was on brake

 

Wow that could have ended badly! Glad you spotted it before it was too late!

 

I drove 300km home from track before I noticed those cracks. Good thing we don’t have much traffic here

anyone know part no. for the TSE 11.75” BBK Wilwood ultralite rotor?

 

so what the hell

 

I bet thermal shock from being red hot and going through a puddle could easily do that.

 

do you Run an ABS system?

It's a standard 8x7" bolt pattern. I run the TSE kit on my personal car. We switched out the Wilwood rotors for a set of PFC rotors. The quality of the iron is substantially higher. the part number you need for the PFC is 299.20.0050.01/02 (01-drivers) (02- pass). We can get them for you. If you want to stick with the wilwood rotors you need a part# 160-12283

 

Yes.



Rotors that came with the TSE 11.75” kit are Wilwood Ultralite 32 Vane Rotor part.no. 160-0471. Maybe the cheapest ones you can get.

Local motorsport shop sells Ultralite HP rotors part.no.160-5841. To get the car running quickly again I probably gonna change that broken one with that

 

few photos

 

That cracking is caused by the ABS system. Your rotors are reaching thermal capacity and then the system hammers the brakes on/off/on/off/on/off. a OEM abs system can destroy some of the toughest rotors.

 

I think you are right! Just look at my front tires from that last brake disc picture. There’s hardly any surface left and it felt like that in track. ABS was kicking whole time

Thanks OGRacing! Now I can sleep again
