To clarify, what model year is your PPV?xcidmigs wrote:Bill,
Are you saying the later style sub frame bushing is different on the PPV? I tried to use the BMR sub frame inserts on my 2011 and found out that the OEM PPV ones I have are not what is used in the camaro/G8 chassis at all, those have big empty spaces in them which the BMR insert cleverly goes into to tighten things up. The PPV ones have no such empty space so maybe that's what you refer to? Sounds like there would be little to improve short of having worn ones replaced with new or a complete poly replacement which I don't think most would be interested in.
The OE cradle bushing PN's are different between WM (2011-2013) and WN (2014-2017)....and what I'm going to determine is whether the later part will backfit to the "early" cars. I like and typically prefer OE solutions, unless there are provable improvements using something else. Not knocking any aftermarket supplier, BMR included--I've got some of their parts sitting on the shelf and how this works out may determine whether I use them.
I'm not sure what actual impact the bushing plays, but won't deny it's different from the sedan bushing, which is a service part, unlike on the Camaro arms. The arm kit wasn't about that bushing, rather it was about the bar mounting method for a 1LE conversion for an early (2010-2011) Camaro--they're the standard production control arm for all 2012-2015 Camaros, AFAIK, and are actually pretty inexpensive individually, but the kit with 2 arms is still best--especially compared to sedan rear control arms, which are much more costly.xcidmigs wrote:They have a different stiffer rubber bushing and also have a 2nd attachment point for the newer style rear anti roll bar but still also has the original style so you can reuse if you wish since the newer bar is much wider and interferes with the OEM PPV rear brake caliper. Oddly GM sells them new as a "kit" which comes with both and is way cheaper than buying a new single OEM one.cal30_sniper wrote: Whats the advantage to the 1LE control arms? Was the swap so you could run wider rims, or do they have some kind of improved suspension geometry?
That the control arms happen to fit the sedan chassis is almost an accident....the ONE thing yet to determine (Maurice is working on this) is to determine whether my eyeballs did not deceive me when I stated that the position of the lower shock mounting bolt holes is slightly higher on the Camaro arms (ie. raising the rear of the car slightly)--which CAN be an issue for a car that's already higher than many of us prefer it to be. If I wasn't so cheap, I would buy the 2015-2017 SS sedan rear lower control arms and not worry about it, but, as noted, the inner bushing is NOT like the setup used on the Camaro kit arms., if that matters.
Interesting book you linked.
