Hey guys I've been grinding on indy with the ZR1 like many of you and have finally got my tune where I like it. On Race medium tires I pull 44 seconds laps all day. Its a pretty neutral tune and only understeers if you totally miss the apex by a mile. good for 200mph through the corners on mediums if you hit it right.
Anyway I figure I would share it and maybe help someone out. Feel free to improve on the tune and post it up if you can work the bugs out.

Downforce
35 front 51 rear
Transmission
249 top speed
Differential
7
25
15

Suspension
Ride height

0 front 0 rear
Spring rate
12.3 front 13.3 rear
Dampeners extension
5 front 8 rear
Dampeners compression
5 front 7 rear
Anti Roll Bars
4 front 7 rear

Alignment
Camber

3.0 front 3.0 rear
Toe
-.20 front 0.00 rear

this tune works really well for me, i tried it on laguna seca as well and it proved to be very stable and easy to handle compared to some of the other zr1 rm tunes

I get a constant

48'xx opening lap
4x 42.520-42.550 lap

With everything stock settings when you get the RM + all mods. I've only adjusted the downforce settings.

Front = Full Down force
Rear = Minimum Down force

Driver Settings = Everything off except ABS on 1.
