Race Tracking Your Supra - Information exchange

[AHP]

I asked KNS about the ER-1s when I was shopping pads for a different car awhile back. About the only thing they had to say was there was almost never a re-order on them. So there's that...


Has anyone tried Cobalt pads? I have the Essex AP kit on my C7Z and recently switched to Cobalt XR1/XR2 from Ferodo DS3.12 and absolutely LOVED them at VIR -- by far the best pad I've run in terms of feel and ability to handle heat, etc... The only downside is they wore very quickly, but so far they seem to be really easy on the rotors, so an equitable trade.

After saying I didn't want to be a guinea pig...I'm going to be your guinea pig for the PFC-11 on the front of the car. I'm waiting on Bimmerworld to get back to me and confirm that they're in stock, but if they are, I'm getting a set.

They are expensive, but not CSG expensive. There is a large base of users in the Porsche and BMW track world (did some looking around on Rennlist and Bimmerforums yesterday). It's a newer compound, but it's still been out a few years.

I thought hard about the Hawk ER-1, as Tire Rack can have them on my doorstep on Monday. There's not a whole lot of feedback on them globally, and my experience with Hawk race pads on the street is very dusty, very loud. (That's with the ancient Blue compound and several sets of DTC-60s on my E36).

anxious to see what you think. What will you be running at the rear?

Well sh!t. Not surprisingly, there are no PFC-11s for the G29 chassis. Talked with Josh at Bimmerworld and he said that PFC makes runs of 20 sets of pads when they get enough orders, and there is no timeframe when they'll get to that threshold.

With the ER-1 feedback from @AHP (Ken at KNS is a good guy...done business with him before), I'll skip them.

The final option, and again...I think I'm doing the guinea pig thing again - Pagid RSL29. It's another enduro compound, they are near-CSG-priced, but Bimmerworld had 1 set left.

A friend ran them on his C8 this year - he loved the feel and the wear, but it wasn't quite enough pad for that car. I'm thinking the Supra (with me driving) will be goldilocks and be just about right.

@Rob_SER , I have the CSG-11 compound on the back of the car. They have plenty of life left, so I'm hoping the brake balance is still good with the a lower mu pad like the RSL29

Sucks about the PFC11, that was the feedback I received from local shops as well, PFC would only make the pads for a big volume customer...

Talked with numerous M2/M3 guys running RSL29 this summer, all very happy.

Friday was a good track day.

It was a hot day but my tires got unbelievably hot @ 158F...recorded by the car.

Not sure if it's a RT660 thing or a combination of the heat that day.

Hoping CRS will wear a bit better

pardon my ignorance.

The tire temperature measurements are done by the car?
Do you have some sort of sensors?

It shows temps on the same screen it shows PSI. Comes this way from the factory.

This is absolutely best screen for me and programed to #8 button.

I think I have mine set to #8 as well .

You lost me at c8 and “feel”, the electronic braking and lack of feel is the biggest complaint tracking owners have told me

Loved the 999s. If you find a place that has them, let us know!

I’ll get in touch with my contacts and find out. 999’s are a great pad, I’ve ran the H16-03 from their racing series and those are amazing.

Ehh.. It's fine, IMO. I get what they were going for but I can see how it may throw some people off. The feel is almost entirely simulated so as brake temps (and braking distances to an extent) increase the pedal feel remains consistent. I acclimated pretty quickly.

Appreciate it! They were definitely better for my long hot sessions at Sebring. Could get on them hard in the afternoons. Track temps well over 100, able to break later on the long straights, then mash em again next big corner, lap after lap. Mega impressed!!

BTW, the temps taking by the sensor are "core" an infrared reading at the surface will be higher.

The ambient was 95 at CMS yesterday. Track temps were actually 150s. My lap times were fastest on the outlap and 1 or 2 hot laps and dropped thereafter.
