Orthojoe's GT4 track thread and ramblings
#1112
I've been using Hankook RS3 and Advan AD08R's for as long as I can remember but with all the rave reviews of the RE71R i must try them.

I wanted to reiterate what orthojoe said... RE71R good to the last drop. He was still pulling 2:00 lap times on these guys. Stiffer springs... totally even wear.
I have the usual suspension bits. Camber in the front is -3.1... Rear is -2.7 I believe. Essentially the same as orthojoe
Also, I'm on Tarrett springs. No DSC

Hey everyone, 3 cars running 19" wheels recently came into this problem. If you have 19" wheels, check for this ASAP.
I was at the track last weekend, and suddenly 2 error messages popped up:
1) brake pad wear, check pads
2) Parking brake fault
My pad wear sensors are not installed on the pads and zip tied out of the way, and I knew my pads were not worn. The car drove just fine, but my parking brake would no longer engage. I finished out the day, thinking that probably one of the pad sensors got caught and destroyed. However, when I got home and took a look at the car, the pad sensors were fine. I took the car into fremont and they discovered this:
This is a wire cable that contains the wires for the brake pad wear sensors and the parking brake controls. It looks like the wheel rubbed through the cable. This is clearance with the oem 20" wheels. No rub and ok, but looks close:
This is what it looks like with my 19x11" OZ wheels:
The cause of the failure was the 19" wheels.
This occured on the REAR PASSENGER side of the car. For whatever reason, the driver side is not affected.
I had doborder take a look at his car because he has the same wheels and setup, and this was his rear passenger side cable:
Same thing. Only caught before the wires were cut through.
Things to consider:
1) These are 19x11 et50 wheels, which are OEM width and offset, but 1" small diameter
2) Car is running aggressive camber in the rear at -2.7 degrees
The cable is mounted to the bracket that you release when doing brake pad changes and have to remove the caliper. The solution is to simply bend the bracket back a bit to get the clearance you need. I had to splice in a wire to fix the completely cut wire and solder together the split wire. Everything is functional again. The wires are all wrapped up. This will do for now until I get around to replacing the entire harness with a new one.

I just replaced the right rear brake hard line. That thing routes through the body like a drunken snake. I screwed the fitting uo changing out the new Spiegler lines. Major PITA.
