1LE Suspension track pack upgrade versus...

Strange, my stock 1LE is very comfortable and predictable at it's limit, extremely balanced and controllable. Perhaps give Pete of Pedders a call. He may be able to troubleshoot for you. The 1LE runs 285/35-20s front and rear, but with the funky mix of 20x10 F and 20x11s R. Perhaps wheel and tire choice has something to do with it.

Going with Pedders Pacecar package and bushes and sways myself. the 1LE stuff is nice but I want better.

Bingo. The secret of it's track success, wider wheels & stickier tires combo.
One who upgrade's Suspension will have to upgrade Wheel/Tires aswell.

I will probably get this pack installed along with 3.91 gears in the near future.

I'd appreciate our resident suspension experts telling me if this is a good deal or if the aftermarket (Pfadt, Pedders, etc.) is a better deal at this price point.

Here is the GM Bill of Materials:

PART # Description Qty
22812942 Front Stab Bar Asm (bar, links, bushing, clamp, nut) 1
22786260 Rear Stab Bar Asm (bar, bushing, clamp, bolt) 1
22761221 Rear Stab Bar Link 2
22812982 Front Strut Asm, LH (strut, spring, mount) 1
22812983 Front Strut Asm, RH (strut, spring, mount) 1
22981391 Rear Shock 2
22922445 Rear Shock Mount, LH 1
22922446 Rear Shock Mount, RH 1
22845487 Rear Toe Link 2
20941932 Rear Cradle Bushing, Front 2
20941933 Rear Cradle Bushing, Rear 2
23102312 Installation Instructions 4

Also will this lower my car?

Will I need to change my wheels to 20x10s on all 4 corners like the 1LE?

Did you just call up your local GM dealer and ask for the 1LE track package?

???

The BOM is from the GM Performance catalog.

If I end up buying it I'll probably buy it from Maureen @ Rodgers Chevrolet.

Hi guys just confirmed my 2013 FE4 SS has the 20941932 front cradle bushings. I can just see the part number from under the car on the exposed part of the bushing. I am thinking the rears are also the same as the track pack kit as well. The track pack must assume 2010-2011 FE3 as a starting point, which has the earlier bushing type. This makes sense as the shock mounts are not needed on the FE4 cars either...I am going to make a leap and say the FE6 front struts are the same "re-valved" FE4 units also.

I am just going to do the rear shocks and the sway bars on top of the FE4.

Edit: also did the rear toe links. These are definitely worth it for the improved spherical bearings at the joints instead of rubber. Made a surprising improvement in the handling. Zero defection. I used to be in the habit of timing a corner to allow for the rear end "to settle". Not needed now. I don't feel any rear end steer on hard acceleration anymore either.

They are not the same. My kit just came in and I went and held the new bushings. The new ones I can not squeeze or flex, the ones on my car I can easily push in with my hand. The ones on my car are just soft rubber.

Maybe the part number for the cradle bushing (20941932) is not correct(?). Regardless, that is the number stamped on my front rear cradle bushing.

The pic below is inverted to read the part number. The white part at the base of the picture is the car body and the number is stamped upside down into the rubber part of the bushing.

I was able to get a pretty good picture of my front cradle bushing (above). Could be that Chevy used up the first solid bushing model stock with some of the '12s/'13s before just using the 1LE version across the board. Or I just got lucky with this one.
