Did some digging on a few open items on the main post this morning. Sorry if I'm addressing stuff that's already been covered between the first post and my post.

This one is interesting. Through google I see what's listed here for the specific PNs being housings only, but through the catalog I see those PNs listed as the entire DSSV strut assembly (top mount/damper, isolators, spring, dust boot, and housing all bolted together). Not sure which I believe more at this point, but I will say I find it odd that the google search sources show it as being the outer housing and spring isolators. Seems like a weird combo to me... I'm also trying to look into why there are 2 different sets of PNs for those. I have an idea of what it could be, but I want to confirm first haha.

Any idea what the reasoning is for the new part numbers for the rear control arms? I had to replace the right rear and ended up with the older number, just curious if there are any physical differences between the two.

I wouldn't stress about it. For example, I had the old and new part number FE4/FEA rear knuckles side-by-side and other than the casting numbers I was unable to discern a useful difference.

I just recently upgraded my FE3 to FE4 suspension. Here is my list of part numbers to include the TTY bolts and all the torque specs. I went with ZL1 springs due to having a supercharger.
Front suspension: -Sway bar – Part # 84052981 (Clamp nuts 16 ft lbs) -Links for sway bar SAME (FE3 and FE4) - part # 23240970 & 23240971 (Nuts 74 ft lbs) -"Ride" Links.

Thank you for this thread!
I put the GM 1LE (FE4) Suspension Kit Upgrade on my FE3 MRC SS with 1LE (FE4) upper and lower rear trailing arms last year and in reading through this thread, to convert the rest of my FE3 parts over to FE4 parts I would only need to buy: Front "Ride" Links. These are the diagonal front-front control arms – part # 84051641 & 84051642 ($204 total) and Rear Knuckles FE4 & FEA = 84258571 & 84258572 ($202 total) and Rear Cradle FE4 = 84053249 ($456 total) Am I missing anything else? I don't want to go full FEA since it's setup for the DSSV/sways. Thanks!

That sounds correct. That said, the rear cradle is a non-trivial swap. Consider the BMR BK063 rear cradle bushing inserts instead, as they're designed for the FE3 cradle bushings and are DIY with shadetree mechanic tools. If cost & labor is no-object, by all means go for the whole rear cradle.

Whole new FE4 cradle is $456 (rounded up) from ThatGMPartsGuy BMR rear cradle lockout kit (BK063) is $360 (rounded up list price). If the bushings in the cradle are the only difference, swapping to the FE4 cradle does not make sense for a non-1LE/ZL1 owner.

Fifty,
When I swapped out the rear knuckles I didn’t notice any physical difference between the two, maybe the bushing compound is different. They were a pain to swap out because you have to remove the rear brakes/e-brake setup and rear hub. |

I may just get the front links and rear cradle bushings and call it a day.

So what would it take to turn
A) FE3 into FE4? B) FE3 into FEA? C) FE4 into FEA? Trying to understand the differences in suspension between the SS and SS 1LE as well as the SS 1LE and the ZL1 LE Ideally my combination would be an SS with the ZL1 1LE suspension package but it might be cost prohibitive. This would also clarify whether I should hunt down a SS 1LE or take the cost savings and start with a base SS Thank you. |

The perfect combo for me for a daily driver with maybe a few track days a year is the SS 1LE, and upgrade the rear cradle bushings to the solid ZL1 1LE bushings. It gives you the rear-end stability of the ZL1 1LE, but with the benefit of having MRC. There is one member here who upgraded his ZL1 (same suspension set-up as the SS 1LE) to the DSSV ZL1 1LE suspension and was not impressed with the ride quality and his lap times did not improve.

My car would certainly see many track days a year and I would not be concerned with the ride quality at all. Im just trying to see what the exact differences are, mostly between the FEA and the FE4. does the FEA come with DSSV? |
