Default Heading back to the track on 10/21

Doing the rear cable mod this weekend, and I have removed the rear spoiler.

The forecast predicts mid 50's.

Hoping for low 12's

Your telling me you don't have a set of spring blockers?

Have you gotten tuned for TFS heads yet?

And good luck!!

Cable mod works, but I don't trust it for safety. I ended up putting coil overs on rear and just crank them up at the track.

I 100% agree. I had spring blockers, but I sold them. I just might try some
ZL1 yellow blockers in the future. Doing the cable mod for now.

Get a kit that goes up to 150, but lets you start at 50 or 100. After 150 the kits get more expensive, at least from what I've seen.

Not that I know of, but it should work. You're looking at a custom application and a couple grand for the pump, plumbing, and air springs. Most of the controllers are set up for self leveling, not going to max for the track. So you'd likely need to hot-wire them or get an advanced controller. Plus, they are typically plumbed in parallel which leads to odd behavior in long sweeping corners.

sorry i meant the 45 dollar bags you through inside a coil spring then run a line and a valve to acceptable area and just fill them with air compressor.
basically you fill it to stiffen the spring, then you can let it out when your not racing.

$45? Got a link? I'll try 'em if they look half-way decent. Milan Dragway has free air and I've got a small compressor at home.

rear wheel drive guys use them all the time to help level out the launch. normally just have to put one in the right rear, but figured 2 back there would probably work well for front wheel drive.


granted they fit in the rear coil spring.
