What is everyone doing for suspension upgrades?
Curious what everyone is doing with their suspension in terms of upgrades? I've currently only done sways on my ZL1 and I'm having issues putting the power down for corner exit. I'm going to do front radius arm inserts and solid sub frame bushings. However, there's a ton of other bushings and I'm wondering what else I should upgrade, especially when I have the rear end out?
When it comes to Polyurethane vs. Delrin I see a lot of debates across the web. Some swear that Polyurethane is too soft and will give over time and the firmness of Delrin reduces wear. But then on the flip side people say the hardness and lack of give in Delrin takes a toll on your suspension components.

I haven't tracked yet ... But going on the car as follows
From Peagasus Camber plates, solid subframe bushing, delrin diff bushing, and outter rear trailing arm bushings From JDP I ordered their ZL1 Track Package minus the stuff that I got from Pegasus Detroit Speed Egineering Components DSS Aluminum 1 Piece DS Stock ZL1 Wheels with Toyo 888s |

Hopefully that takes care of any suspension issues...
Plan is to run Thunderhill on Feb 13 stock since it will be cutting time short to get everything on the car and then throw the stuff on it, run MRLS Sonoma and more thunderhill throughout the year |

Again, I don't know much about their sways, but some sway bars are indeed a bit too stiff. By the way, FYI, stiffer shocks/springs with softer sways is what the Z/28 package is all about.

Yep DSE sway bars ... JDP seems to have a ton of track experience in their shop car... Went with their recommendation...
See how it goes ... Be a while before I know the proper way around a track anyhow... |

Right now by biggest dilemma is to go with polyurethane or delrin on bushings.

The tips about at least the rear bar are still mostly valid with your response. I don't follow your car specifically what tires and alignment? Tire pressures and maybe some tire wear pics would be sweet as well. (There are some good ol boys here that can dissect that)
As per your bushing question each have pros and cons. Check the melt point for those materials and keep in mind your hobby of driving this heavy Chevy 90%!! Some bushing upgrades really can help with eliminating some wonky and or unpredictable deflections all going their own ways. They can makes the car easier to drive but much less forgiving with the loud peddle and good ol snap steering hehe. my car is a completely hodgepodge set up that works great for me I'm on stock sways and old geometries so specfic experience with your set up I lack.

I'm running a fairly simple setup for the moment
Rear cradle bushing inserts Front radius arm inserts Rear 32mm hollow bar Camber plates Alignment changes (this is still a work in progress) Other than that, stock 1le gear (at the track 10x20 rims on all corners) EDIT truetrac differential also

I've eventually come around to accept some moderate understeer in exchange for better power application on exit. If that's not acceptable, the ultimate fix is either to move the engine closer to the rear axle or to put some torque to the front wheels. Those are difficult modifications to perform on a budget

At this point and after talking with Pete @ JPSS I've decided to go with DSE solid sub frame bushings and adjustable toe rods with spherical bushings. Pete feels that the OEM bushings on the ZL1 are sufficient and unnecessary to change out. Quote:

Too much to list again... All on the first page of my build thread... -Don

Delrin is a Polymer that has to be CNC Machined to size. It is Solid. I like my Race Cars to be stiff, but as if you do that it adds stress to other components. Also if you run a car super stiff, there is less room for error in your driving! Now it depends on which Bushings you are looking to change. Some (like the Cradle Bushings) you can go as hard as you want without issues. Diff Bushings if you go Hard, it will transmit a lot of NVH, same with Motor Mounts. |
